Climate crisis: today's children face lives with tiny carbon footprints | Environment |... - 0 views

  • Children born today will have to live their lives with drastically smaller carbon footprints than their grandparents if climate change is to be controlled.
  • Fast, deep cuts in global emissions from energy, transport and food are needed to keep temperature rises in check and an analysis has shown this means the new generation will have lifetime carbon budgets almost 90% lower than someone born in 1950.
  • “Those in positions of power – from politicians to business leaders – that have benefited from a much higher lifetime carbon budget have a duty to act to ensure a liveable planet for current and future generations,”

  • t then calculates how much the average citizen on Earth can emit over their lifetime to keep temperature rises below 1.5C or 2C above pre-industrial levels, the goal of the world’s nations to avoid climate catastrophe.
  • The children and young people taking part in the youth strikes (born 1997-2012) will have carbon budgets just one sixth those of their baby boomer grandparents (1946-1964).
  • He said it is the first systematic use of emissions data to inform the debate about intergenerational responsibility for climate change and had produced some “uncomfortable numbers”.
  • There is a currently a wide gap between the average annual emissions of a US citizen (16.9 tonnes) and an Indian citizen (1.9 tonnes)
  • in a second analysis, Carbon Brief posited a future carbon budget that would be the same for every citizen on the planet. This would mean that the budget for a child born today in the US is even lower, 97% lower than that of that of their grandparents. For someone born today in Europe, their budget would be 94% lower

Wind and Solar Power Advance, but Carbon Refuses to Retreat - The New York Times - 0 views

  • carbon intensity of energy. Advertisement Continue reading the main story The term refers to a measure of the amount of CO2 spewed into the air for each unit of energy consumed. It offers some bad news: It has not budged since that chilly autumn day in Kyoto 20 years ago.
  • Even among the highly industrialized nations in the Organization for Economic Cooperation and Development, the carbon intensity of energy has declined by a paltry 4 percent since then
  • Perhaps renewables are not the answer.
  • ...10 more annotations...
  • Over the past 10 years, governments and private investors have collectively spent $2 trillion on infrastructure to draw electricity from the wind and the sun,
  • Capacity from renewable sources has grown by leaps and bounds, outpacing growth from all other sources — including coal, natural gas and nuclear power — in recent years. Solar and wind capacity installed in 2015 was more than 10 times what the International Energy Agency had forecast a decade before.
  • Still, except for very limited exceptions, all this wind and sun has not brought about much decarbonization. Indeed, it has not added much clean power to the grid.
  • Environmental Progress performed an analysis of the evolution of the carbon intensity of energy in 68 countries since 1965. It found no correlation between the additions of solar and wind power and the carbon intensity of energy: Despite additions of renewable capacity, carbon intensity remained flat.
  • Integrating renewable sources requires vast investments in electricity transmission — to move power from intermittently windy and sunny places to places where power is consumed. It requires maintaining a backstop of idle plants that burn fossil fuel, for the times when there is no wind or sun to be had. It requires investing in power-storage systems at a large scale.
  • These costs will ultimately be reflected in power prices. One concern is that by raising the retail cost of electricity they will discourage electrification, encouraging consumers to rely on alternative energy sources like gas — and pushing CO2 emissions up.
  • Another concern is that they will drive wholesale energy prices down too far. Because they produce the most energy when the sun is up and the wind is blowing, renewable generators can flood the grid at critical times of the day, slashing the price of power. This not only threatens the solvency of nuclear reactors, which cannot shut down on a dime and must therefore pay for the grid to accept their power, but also reduces the return on additional investment in renewables.
  • there is some evidence that among investors, at least, the excitement may be waning. After half a decade of sustained increases, investment in solar and wind energy has been fairly flat since 2010, at around $250 billion per year. While that is a lot of money, it is nowhere near enough.
  • “We will need twice as much investment over a sustained period of time to get anywhere close to achieving 2 degrees,”
  • I would suggest that the challenge is not just to raise more money. Building a zero-carbon energy system requires broader thinking about the technological mix.

History of the Light Bulb | Lighting Basics | Bulbs.com - 0 views

  • The electric light, one of the everyday conveniences that most affects our lives, was not “invented” in the traditional sense in 1879 by Thomas Alva Edison, although he could be said to have created the first commercially practical incandescent light.
  • Edison is often credited with the invention because his version was able to outstrip the earlier versions because of a combination of three factors: an effective incandescent material, a higher vacuum than others were able to achieve and a high resistance that made power distribution from a centralized source economically viable.
  • In 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the Electric Arc lamp.
  • ...8 more annotations...
  • However, he continued to test several types of material for metal filaments to improve upon his original design and by Nov 4, 1879, he filed another U.S. patent for an electric lamp using "a carbon filament or strip coiled and connected ... to platina contact wires."
  • They built their lamps with different sizes and shapes of carbon rods held between electrodes in glass cylinders filled with nitrogen. Woodward and Evans attempted to commercialize their lamp, but were unsuccessful.
  • In 1850 an English physicist named Joseph Wilson Swan created a “light bulb” by enclosing carbonized paper filaments in an evacuated glass bulb. And by 1860 he had a working prototype, but the lack of a good vacuum and an adequate supply of electricity resulted in a bulb whose lifetime was much too short to be considered an effective prodcer of light.
  • Although the patent described several ways of creating the carbon filament including using "cotton and linen thread, wood splints, papers coiled in various ways," it was not until several months after the patent was granted that Edison and his team discovered that a carbonized bamboo filament could last over 1200 hours.
  • 1906 - The General Electric Company were the first to patent a method of making tungsten filaments for use in incandescent lightbulbs. Edison himself had known tungsten would eventually prove to be the best choice for filaments in incandescent light bulbs, but in his day, the machinery needed to produce the wire in such a fine form was not available.
  • 1920s - The first frosted lightbulb is produced and adjustable power beam bulbs for car headlamps, and neon lighting.
  • Modern incandescent bulbs are not energy efficient – less than 10% of electrical power supplied to the bulb is converted into visible light. The remaining energy is lost as heat. However these inefficient light bulbs are still widely used today due to many advantages such as: wide, low-cost availability easy incorporation into electrical systems adaptable for small systems low voltage operation, such as in battery powered devices wide shape and size availability
  • with LED prices falling significantly, the future does seem to belong to the LED.

Opinion | Climate Change Is Real. Markets, Not Governments, Offer the Cure. - The New Y... - 0 views

  • For years, I saw myself not as a global-warming denier (a loaded term with its tendentious echo of Holocaust denial) but rather as an agnostic on the causes of climate change and a scoffer at the idea that it was a catastrophic threat to the future of humanity.
  • It’s not that I was unalterably opposed to the idea that, by pumping carbon dioxide into the atmosphere, modern civilization was contributing to the warming by 1 degree Celsius and the inches of sea-level rise the planet had experienced since the dawn of the industrial age. It’s that the severity of the threat seemed to me wildly exaggerated and that the proposed cures all smacked of old-fashioned statism mixed with new-age religion.
  • Hadn’t we repeatedly lived through previous alarms about other, allegedly imminent, environmental catastrophes that didn’t come to pass, like the belief, widespread in the 1970s, that overpopulation would inevitably lead to mass starvation? And if the Green Revolution had spared us from that Malthusian nightmare, why should we not have confidence that human ingenuity wouldn’t also prevent the parade of horribles that climate change was supposed to bring about?
  • ...63 more annotations...
  • I had other doubts, too. It seemed hubristic, or worse, to make multitrillion-dollar policy bets based on computer models trying to forecast climate patterns decades into the future. Climate activists kept promoting policies based on technologies that were either far from mature (solar energy) or sometimes actively harmful (biofuels).
  • Expensive efforts to curb greenhouse gas emissions in Europe and North America seemed particularly fruitless when China, India and other developing countries weren’t about to curb their own appetite for fossil fuels
  • just how fast is Greenland’s ice melting right now? Is this an emergency for our time, or is it a problem for the future?
  • His pitch was simple: The coastline we have taken for granted for thousands of years of human history changed rapidly in the past on account of natural forces — and would soon be changing rapidly and disastrously by man-made ones. A trip to Greenland, which holds one-eighth of the world’s ice on land (most of the rest is in Antarctica) would show me just how drastic those changes have been. Would I join him?
  • Greenland is about the size of Alaska and California combined and, except at its coasts, is covered by ice that in places is nearly two miles thick. Even that’s only a fraction of the ice in Antarctica, which is more than six times as large
  • Greenland’s ice also poses a nearer-term risk because it is melting faster. If all its ice were to melt, global sea levels would rise by some 24 feet. That would be more than enough to inundate hundreds of coastal cities in scores of nations, from Jakarta and Bangkok to Copenhagen and Amsterdam to Miami and New Orleans.
  • There was also a millenarian fervor that bothered me about climate activism, with its apocalyptic imagery (the Statue of Liberty underwater) and threats of doom unless we were willing to live far more frugally.
  • “We haven’t had a good positive mass balance year since the late 1990s,” he told me in a follow-on email when I asked him to explain the data for me. The losses can vary sharply by year. The annualized average over the past 30 years, he added, is 170 gigatons per year. That’s the equivalent of about 5,400 tons of ice loss per second. That “suggests that Greenland ice loss has been tracking the I.P.P.C. worse-case, highest-carbon-emission scenario.
  • The data shows unmistakably that Greenland’s ice is not in balance. It is losing far more than it is gaining.
  • scientists have been drilling ice-core samples from Greenland for decades, giving them a very good idea of climatic changes stretching back thousands of years. Better yet, a pair of satellites that detect anomalies in Earth’s gravity fields have been taking measurements of the sheet regularly for nearly 20 years, giving scientists a much more precise idea of what is happening.
  • it’s hard to forecast with any precision what that means. “Anyone who says they know what the sea level is going to be in 2100 is giving you an educated guess,” said NASA’s Willis. “The fact is, we’re seeing these big ice sheets melt for the first time in history, and we don’t really know how fast they can go.”
  • His own educated guess: “By 2100, we are probably looking at more than a foot or two and hopefully less than seven or eight feet. But we are struggling to figure out just how fast the ice sheets can melt. So the upper end of range is still not well known.”
  • On the face of it, that sounds manageable. Even if sea levels rise by eight feet, won’t the world have nearly 80 years to come to grips with the problem, during which technologies that help us mitigate the effects of climate change while adapting to its consequences are likely to make dramatic advances?
  • Won’t the world — including countries that today are poor — become far richer and thus more capable of weathering the floods, surges and superstorms?
  • The average rate at which sea level is rising around the world, he estimates, has more than tripled over the past three decades, to five millimeters a year from 1.5 millimeters. That may still seem minute, yet as the world learned during the pandemic, exponential increases have a way of hitting hard.
  • “When something is on a straight line or a smooth curve, you can plot its trajectory,” Englander said. “But sea level, like earthquakes and mudslides, is something that happens irregularly and can change rather quickly and surprise us. The point is, you can no longer predict the future by the recent past.”
  • In The Wall Street Journal’s editorial pages, where I used to work, the theoretical physicist Steven Koonin, a former under secretary for science in the Obama administration’s Energy Department, cast doubt on the threat from Thwaites in a voice that could have once been mine. He also thinks the risks associated with Greenland’s melting are less a product of human-induced global warming than of natural cycles in North Atlantic currents and temperatures, which over time have a way of regressing to the mean.
  • Even the poorest countries, while still unacceptably vulnerable, are suffering far fewer human and economic losses to climate-related disasters.
  • Another climate nonalarmist is Roger Pielke Jr., a professor of environmental studies at the University of Colorado Boulder. I call Pielke a nonalarmist rather than a skeptic because he readily acknowledges that the challenges associated with climate change, including sea-level rise, are real, serious and probably unstoppable, at least for many decades.
  • “If we have to have a problem,” he told me when I reached him by phone, “we probably want one with a slow onset that we can see coming. It’s not like an asteroid coming from space.”
  • “Since the 1940s, the impact of floods as a proportion of U.S. gross domestic product has dropped by 70 percent-plus,” Pielke said. “We see this around the world, across phenomena. The story is that fewer people are dying and we are having less damage proportional to G.D.P.”
  • “Much climate reporting today highlights short-term changes when they fit the narrative of a broken climate but then ignores or plays down changes when they don’t, often dismissing them as ‘just weather,’” he wrote in February.
  • Global warming is real and getting worse, Pielke said, yet still it’s possible that humanity will be able to adapt to, and compensate for, its effects.
  • A few years ago, I would have found voices like Koonin’s and Pielke’s persuasive. Now I’m less sure. What intervened was a pandemic.
  • That’s what I thought until the spring of 2020, when, along with everyone else, I experienced how swiftly and implacably nature can overwhelm even the richest and most technologically advanced societies. It was a lesson in the sort of intellectual humility I recommended for others
  • It was also a lesson in thinking about risk, especially those in the category known as high-impact, low-probability events that seem to be hitting us with such regularity in this century: the attacks of Sept. 11, 2001; the tsunamis of 2004 and 2011, the mass upheavals in the Arab world
  • What if the past does nothing to predict the future? What if climate risks do not evolve gradually and relatively predictably but instead suddenly soar uncontrollably? How much lead time is required to deal with something like sea-level rise? How do we weigh the risks of underreacting to climate change against the risks of overreacting to it?
  • I called Seth Klarman, one of the world’s most successful hedge-fund managers, to think through questions of risk. While he’s not an expert on climate change, he has spent decades thinking deeply about every manner of risk
  • And we will almost certainly have to do it from sources other than Russia, China, the Democratic Republic of Congo and other places that pose unacceptable strategic, environmental or humanitarian risks
  • “If you face something that is potentially existential,” he explained, “existential for nations, even for life as we know it, even if you thought the risk is, say, 5 percent, you’d want to hedge against it.”
  • “One thing we try to do,” he said, “is we buy protection when it’s really inexpensive, even when we think we may well not need it.” The forces contributing to climate change, he noted, echoing Englander, “might be irreversible sooner than the damage from climate change has become fully apparent. You can’t say it’s far off and wait when, if you had acted sooner, you might have dealt with it better and at less cost. We have to act now.”
  • In other words, an ounce of prevention is worth a pound of cure. That’s particularly true if climate change is akin to cancer — manageable or curable in its earlier stages, disastrous in its later ones.
  • As I’ve always believed, knowing there is grave risk to future generations — and expecting current ones to make immediate sacrifices for it — defies most of what we know about human nature. So I began to think more deeply about that challenge, and others.
  • For the world to achieve the net-zero goal for carbon dioxide emissions by 2050, according to the International Energy Agency, we will have to mine, by 2040, six times the current amounts of critical minerals — nickel, cobalt, copper, lithium, manganese, graphite, chromium, rare earths and other minerals and elements — needed for electric vehicles, wind turbines and solar panels.
  • The poster child for this kind of magical thinking is Germany, which undertook a historic Energiewende — “energy revolution” — only to come up short. At the turn of the century, Germany got about 85 percent of its primary energy from fossil fuels. Now it gets about 78 percent, a puny reduction, considering that the country has spent massive sums on renewables to increase the share of electricity it generates from them.
  • As in everything else in life, so too with the environment: There is no such thing as a free lunch. Whether it’s nuclear, biofuels, natural gas, hydroelectric or, yes, wind and solar, there will always be serious environmental downsides to any form of energy when used on a massive scale. A single industrial-size wind turbine, for instance, typically requires about a ton of rare earth metals as well as three metric tons of copper, which is notoriously destructive and dirty to mine.
  • no “clean energy” solution will easily liberate us from our overwhelming and, for now, inescapable dependence on fossil fuels.
  • Nobody brings the point home better than Vaclav Smil, the Canadian polymath whose most recent book, “How the World Really Works,” should be required reading for policymakers and anyone else interested in a serious discussion about potential climate solutions.
  • “I’ve talked to so many experts and seen so much evidence,” he told me over Zoom, “I’m convinced the climate is changing, and addressing climate change has become a philanthropic priority of mine.”
  • Things could turn a corner once scientists finally figure out a technical solution to the energy storage problem. Or when governments and local actors get over their NIMBYism when it comes to permitting and building a large energy grid to move electricity from Germany’s windy north to its energy-hungry south. Or when thoughtful environmental activists finally come to grips with the necessity of nuclear energy
  • Till then, even as I’ve come to accept the danger we face, I think it’s worth extending the cancer metaphor a little further: Just as cancer treatments, when they work at all, can have terrible side effects, much the same can be said of climate treatments: The gap between an accurate diagnosis and effective treatment remains dismayingly wide
  • Only when countries like Vietnam and China turned to a different model, of largely bottom-up, market-driven development, did hundreds of millions of people get lifted out of destitution.
  • the most important transformation has come in agriculture, which uses about 70 percent of the world’s freshwater supply.
  • Farmers gradually adopted sprinkler and drip irrigation systems, rather than more wasteful flood irrigation, not to conserve water but because the technology provided higher crop yields and larger profit margins.
  • Water shortages “will spur a revolutionary, aggressive approach to getting rid of flood irrigation,” said Seth Siegel, the chief sustainability officer of the Israeli AgTech company N-Drip. “Most of this innovation will be driven by free-market capitalism, with important incentives from government and NGOs.
  • meaningful environmental progress has been made through market forces. In this century, America’s carbon dioxide emissions across fuel types have fallen to well below 5,000 million metric tons per year, from a peak of about 6,000 million in 2007, even as our inflation-adjusted G.D.P. has grown by over 50 percent and total population by about 17 percent.
  • 1) Engagement with critics is vital. Insults and stridency are never good tools of persuasion, and trying to cow or censor climate skeptics into silence rarely works
  • the biggest single driver in emissions reductions from 2005 to 2017 was the switch from coal to natural gas for power generation, since gas produces roughly half the carbon dioxide as coal. This, in turn, was the result of a fracking revolution in the past decade, fiercely resisted by many environmental activists, that made the United States the world’s largest gas producer.
  • In the long run, we are likelier to make progress when we adopt partial solutions that work with the grain of human nature, not big ones that work against it
  • Renewables, particularly wind power, played a role. So did efficiency mandates.
  • The problem with our civilization isn’t overconfidence. It’s polarization, paralysis and a profound lack of trust in all institutions, including the scientific one
  • Devising effective climate policies begins with recognizing the reality of the social and political landscape in which all policy operates. Some thoughts on how we might do better:
  • They may not be directly related to climate change but can nonetheless have a positive impact on it. And they probably won’t come in the form of One Big Idea but in thousands of little ones whose cumulative impacts add up.
  • 2) Separate facts from predictions and predictions from policy. Global warming is a fact. So is the human contribution to it. So are observed increases in temperature and sea levels. So are continued increases if we continue to do more of the same. But the rate of those increases is difficult to predict even with the most sophisticated computer modeling
  • 3) Don’t allow climate to become a mainly left-of-center concern. One reason the topic of climate has become so anathema to many conservatives is that so many of the proposed solutions have the flavor, and often the price tag, of old-fashioned statism
  • 4) Be honest about the nature of the challenge. Talk of an imminent climate catastrophe is probably misleading, at least in the way most people understand “imminent.”
  • A more accurate description of the challenge might be a “potentially imminent tipping point,” meaning the worst consequences of climate change can still be far off but our ability to reverse them is drawing near. Again, the metaphor of cancer — never safe to ignore and always better to deal with at Stage 2 than at Stage 4 — can be helpful.
  • 5) Be humble about the nature of the solutions. The larger the political and financial investment in a “big fix” response to climate change on the scale of the Energiewende, the greater the loss in time, capital and (crucially) public trust when it doesn’t work as planned
  • 6) Begin solving problems our great-grandchildren will face. Start with sea-level rise
  • We can also stop providing incentives for building in flood-prone areas by raising the price of federal flood insurance to reflect the increased risk more accurately.
  • 7) Stop viewing economic growth as a problem. Industrialization may be the leading cause of climate change. But we cannot and will not reverse it through some form of deindustrialization, which would send the world into poverty and deprivation
  • 8) Get serious about the environmental trade-offs that come with clean energy. You cannot support wind farms but hinder the transmission lines needed to bring their power to the markets where they are needed.
  • 9) A problem for the future is, by its very nature, a moral one. A conservative movement that claims to care about what we owe the future has the twin responsibility of setting an example for its children and at the same time preparing for that future.

Once-Unpopular Carbon Credits Emerge as One of the World's Best Investments - WSJ - 0 views

  • The resurgence in carbon-credit prices began in mid-2017 when EU policy makers agreed to sharply reduce the number of available credits. That has pushed up prices and allowed the carbon market to help fulfill its purpose of punishing excess polluters.
  • The idea of a trading program was first enshrined in the 1997 Kyoto Protocols. The EU launched its program in 2005, granting credits to individual countries, who in turn pass out credits or auction them to carbon-producing companies, like steelmakers and power plants, which can either use or trade them. For every ton of carbon the polluters generate, regulators require them to possess a credit.
  • An excess in credits in recent years caused prices to plunge as industry suffered across the continent during the financial crisis, leaving unused credits in the system for years afterward
  • ...3 more annotations...
  • Prices have shot up since the reforms were agreed on. Fresh interest from speculators has also boosted prices, creating a “positive feedback loop,”
  • “The market as a whole and our customer base for sure is more interested. That’s industrial installations but also speculators,”
  • The higher prices mean that it now costs industrial polluters almost as much to use coal as it does to use cleaner natural gas. Putting the two markets on an equal footing means carbon prices are driven by factors similar to the ones that affect gas prices, such as high summer temperatures.

Natural Gas Companies Have Their Own Plans To Go Low-Carbon : NPR - 0 views

  • Fossil fuel companies face an existential threat as more governments and businesses tackle climate change and vow to zero-out carbon emissions. President Biden has a plan to do that in the U.S., and some gas companies are recognizing they need a survival plan for the future.
  • Dozens of cities have moved to restrict or ban natural gas in new buildings and use renewable electricity for heating and cooking instead. But gas companies, which have launched expensive public-relations campaigns in response, say that's not the only way to decarbonize.
  • Heiting says NW Natural could continue fueling home furnaces, appliances and industrial plants with a carbon-neutral mixture of renewable gas that would come from a variety of sources.
  • ...4 more annotations...
  • Heiting says burning that methane is a way of reducing the greenhouse gas emissions that are currently contributing to climate change. Methane released from dairy farms, for example, has far more global warming potential than the carbon dioxide released when that methane is burned.
  • So the company would then mix that lower-carbon gas with hydrogen gas, which has no carbon emissions when it's burned.
  • "This is not going to happen without policy support," she says. "We need production tax credits for renewable natural gas and hydrogen just like we put in place for wind and solar."
  • "Hydrogen is pretty well suited to solve a lot of problems at once and really be this unifier between renewable energy and our society's energy needs," Ramsey says. "This is a big opportunity for oil and gas companies, but also for electric utilities and renewable developers."

  • By the early 2000s, Japan had made substantial progress in curbing carbon dioxide emissions through the use of nuclear power. But the meltdown of a nuclear power plant in Fukushima after a devastating earthquake and tsunami in 2011 led to a widespread shutdown of the country’s energy-producing reactors, which had generated roughly a third of Japan’s total power supply. Only a handful of the plants have since restarted.
  • Short on energy sources, Japan decided to reinvest in coal.
  • Japan currently plans to reduce — but not eliminate — its dependence on coa
  • The country has also vowed to end contentious government subsidies for the export of coal-fired power technology to developing nations, where the use of coal for electricity continues to rise
  • Further efforts to decrease Japan’s domestic commitment to coal will likely meet powerful resistance from Japanese industry, which is still heavily dependent on the fuel
  • Japan is already considering a substantial increase in its supply of wind and solar power, and it is also looking at newer, less-established technologies, such as plants that burn ammonia or hydrogen.
  • Mr. Suga said that Japan would continue to develop nuclear power with “maximum priority on safety,”
  • Movement toward the new goal had already started on the local level, where 150 municipal governments have pledged to be carbon neutral by midcentury.

  • Preventing a climate catastrophe will require “a transformation of the energy system that has underwritten modern society,”
  • Japan will be carbon neutral by 2050, its prime minister said on Monday
  • The announcement came just weeks after China, Japan’s regional rival, said it would reduce its net carbon emissions to zero by 2060.

Obama's Ambitious Global Warming Action Plan - NYTimes.com - 0 views

New Studies of Permian Extinction Shed Light on the 'Great Dying' - NYTimes.com - 0 views

  • Dr. Clapham and his co-author, Jonathan L. Payne, a Stanford geochemist, concluded that animals with skeletons or shells made of calcium carbonate, or limestone, were more likely to die than those with skeletons of other substances. And animals that had few ways of protecting their internal chemistry were more apt to disappear. Being widely dispersed across the planet was little protection against extinction, and neither was being numerous. The deaths happened throughout the ocean. Nor was there any correlation between extinction and how a creature moved or what it ate. Instead, the authors concluded, the animals died from a lack of dissolved oxygen in the water, an excess of carbon dioxide, a reduced ability to make shells from calcium carbonate, altered ocean acidity and higher water temperatures. They also concluded that all these stresses happened rapidly and that each one amplified the effects of the others. That led to a wholesale change in the ocean’s dominant animals within just 200,000 years, or perhaps much less, Dr. Clapham said.
  • So what happened 252 million years ago to cause those physiological stresses in marine animals? Additional clues from carbon, calcium and nitrogen isotopes of the period, as well as from organic geochemistry, suggest a “perturbation of the global carbon cycle,” the scientists’ second paper concluded — a huge infusion of carbon into the atmosphere and the ocean.
  • scientists suspect that the answer lies in the biggest volcanic event of the past 500 million years — the eruptions that formed the Siberian Traps, the stairlike hilly region in northern Russia. The eruptions sent catastrophic amounts of carbon gas into the atmosphere and, ultimately, the oceans; that led to long-term ocean acidification, ocean warming and vast areas of oxygen-poor ocean water

Climate Change Threatens the World's Food Supply, United Nations Warns - The New York T... - 0 views

  • The world’s land and water resources are being exploited at “unprecedented rates,” a new United Nations report warns, which combined with climate change is putting dire pressure on the ability of humanity to feed itself.
  • A half-billion people already live in places turning into desert, and soil is being lost between 10 and 100 times faster than it is forming
  • “People’s lives will be affected by a massive pressure for migration,” said Pete Smith, a professor of plant and soil science at the University of Aberdeen and one of the report’s lead authors. “People don’t stay and die where they are. People migrate.”

  • Climate change will make those threats even worse, as floods, drought, storms and other types of extreme weather threaten to disrupt, and over time shrink, the global food supply
  • food shortages could lead to an increase in cross-border migration.
  • A particular danger is that food crises could develop on several continents at once
  • “The potential risk of multi-breadbasket failure is increasing,” she said. “All of these things are happening at the same time.”
  • The report also offered a measure of hope, laying out pathways to addressing the looming food crisis, though they would require a major re-evaluation of land use and agriculture worldwide as well as consumer behavior
  • Proposals include increasing the productivity of land, wasting less food and persuading more people to shift their diets away from cattle and other types of meat.
  • “One of the important findings of our work is that there are a lot of actions that we can take now. They’re available to us,” Dr. Rosenzweig said. “But what some of these solutions do require is attention, financial support, enabling environments.”
  • activities such as draining wetlands — as has happened in Indonesia and Malaysia to create palm oil plantations, for example — is particularly damaging. When drained, peatlands, which store between 530 and 694 billion tons of carbon dioxide globally, release that carbon dioxide back into the atmosphere.
  • Between 2010 and 2015 the number of migrants from El Salvador, Guatemala and Honduras showing up at the United States’ border with Mexico increased fivefold, coinciding with a dry period that left many with not enough food and was so unusual that scientists suggested it bears the signal of climate change
  • As a warming atmosphere intensifies the world’s droughts, flooding, heat waves, wildfires and other weather patterns, it is speeding up the rate of soil loss and land degradation, the report concludes.
  • Higher concentrations of carbon dioxide in the atmosphere
  • will also reduce food’s nutritional quality, even as rising temperatures cut crop yields and harm livestock
  • In some cases, the report says, a changing climate is boosting food production because, for example, warmer temperatures will mean greater yields of some crops at higher latitudes. But on the whole, the report finds that climate change is already hurting the availability of food because of decreased yields and lost land from erosion, desertification and rising seas
  • Overall if emissions of greenhouse gases continue to rise, so will food costs, according to the report, affecting people around the world.
  • “You’re sort of reaching a breaking point with land itself and its ability to grow food and sustain us,”
  • agriculture itself is also exacerbating climate change.
  • the window to address the threat is closing rapidly
  • Every 2.5 acres of peatlands release the carbon dioxide equivalent of burning 6,000 gallons of gasoline
  • And the emissions of carbon dioxide continues long after the peatlands are drained. Of the five gigatons of greenhouse gas emissions that are released each year from deforestation and other land-use changes, “One gigaton comes from the ongoing degradation of peatlands that are already drained,”
  • (By comparison, the fossil fuel industry emitted about 37 gigatons of carbon dioxide last year, according to the institute.)
  • cattle are significant producers of methane, another powerful greenhouse gas, and an increase in global demand for beef and other meats has fueled their numbers and increased deforestation in critical forest systems like the Amazon
  • each year, the amount of forested land that is cleared — much of that propelled by demand for pasture land for cattle — releases the emissions equivalent of driving 600 million cars
  • The authors urge changes in how food is produced and distributed, including better soil management, crop diversification and fewer restrictions on trade
  • They also call for shifts in consumer behavior, noting that at least one-quarter of all food worldwide is wasted
  • But protecting the food supply and cutting greenhouse emissions can also come into conflict with each other, forcing hard choices. For instance, the widespread use of strategies such as bioenergy — like growing corn to produce ethanol — could lead to the creation of new deserts or other land degradation
  • The report also calls for institutional changes, including better access to credit for farmers in developing countries and stronger property rights
  • The same is true for planting large numbers of trees (something often cited as a powerful strategy to pull carbon dioxide out of the atmosphere), which can push crops and livestock onto less productive land
  • But it would also increase food prices as much as 80 percent by 2050.
  • “We cannot plant trees to get ourselves out of the problem that we’re in,
  • “The trade-offs that would keep us below 1.5 degrees, we’re not talking about them. We’re not ready to confront them yet.”
  • Preventing global temperatures from rising more than 1.5 degrees Celsius is likely to require both the widespread planting of trees as well as “substantial” bioenergy to help reduce the use of fossil fuels
  • “Above 2 degrees of global warming there could be an increase of 100 million or more of the population at risk of hunger,” Edouard Davin, a researcher at ETH Zurich and an author of the report, said by email. “We need to act quickly
  • Planting as many trees as possible would reduce the amount of greenhouse gases in the atmosphere by about nine gigatons each year
  • “Agricultural practices that include indigenous and local knowledge can contribute to overcoming the combined challenges of climate change, food security, biodiversity conservation, and combating desertification and land degradation,”
  • an average of three people were killed per week defending their land in 2018, with more than half of them killed in Latin America.
  • the longer policymakers wait, the harder it will be to prevent a global crisis. “Acting now may avert or reduce risks and losses, and generate benefits to society,” the authors wrote. Waiting to cut emissions, on the other hand, risks “irreversible loss in land ecosystem functions and services required for food, health, habitable settlements and production.”

How the Fed Should Fight Climate Change - The Atlantic - 0 views

  • Mark Carney, a former Goldman Sachs director who now leads the Bank of England, sounded a warning. Global warming, he said, could send the world economy spiraling into another 2008-like crisis
  • He called for central banks to act aggressively and immediately to reduce the risk of climate-related catastrophe
  • the U.S. Federal Reserve was the pivotal American institution in stopping a second Great Depression. Its actions were “historically unprecedented, spectacular in scale,” he writes, and widely understood by experts to be the “decisive innovation of the crisis.”
  • ...45 more annotations...
  • “If the world is to cope with climate change, policymakers will need to pull every lever at their disposal,” he writes. “Faced with this threat, to indulge in the idea that central banks, as key agencies of the state, can limit themselves to worrying about financial stability … is its own form of denial.”
  • In England, by contrast, Carney has convened 33 central banks to investigate how to “green the financial system.” According to Axios, every powerful central bank is working with him—except for Banco do Brasil and the Fed.
  • Mark Carney, the governor of the Bank of England, in 2015, in a speech which has subsequently received massive coverage—and he is a man, after all, absolutely of the global financial establishment—coined the idea of a climate Minsky moment. [Editor’s note: A Minsky moment is when an asset’s price suddenly collapses after a long period of growth.]
  • We would need [fossil-fuel assets] to be on the balance sheet of actors who were under huge pressure in a fire-sale situation and who couldn’t deal with a sudden revaluation. We would need an entire network of causation to be there, which is what produced the unique crisis of 2007 to 2008.
  • So imagine that we stay on our current path, and we’re headed toward 3 or 4 degrees’ [Celsius] temperature change. And then imagine some of the nonlinearities kick in, which the climate scientists tell us about, and we face a Fukushima-style event.
  • What happens next? You then get nervous democratic politicians—and not necessarily those who are known for their populism, but just nervous democratic politicians—suddenly deciding that we have to stop doing one or another part of our carbon-based economy. It has to stop, and it has to stop immediately. And then you get big shocks. Then you get sudden revaluations.
  • In other words, the success of the delaying tactics of the carbon lobby create a situation in which we’re then faced with the possibility of a sudden regulatory shock
  • “One-third of equity and fixed income assets issued in global financial markets can be classified as belonging to the natural resource and extraction sectors, as well as carbon-intensive power utilities, chemicals, construction, and industrial goods firms.”
  • Whether that will, in fact, ease the formation of majorities in Congress is another question. Because, after all, it does somehow have to get through the Senate, you know.
  • Germany is far, far more exposed. A huge slice of their economy is basically all about internal combustion engines, and so that number includes all of those stocks, for sure.
  • If we saw a huge shock to, say, European equity [exchange-traded funds], which were heavily in German automotive, that’s the sort of trigger that we might be looking at.
  • This is not simply a zero-sum game; this is a structural transformation that has many very attractive properties. There’s loads of excellent jobs that could be created in this kind of transition.There’s no reason why, even by conventional GDP-type metrics, it need even be associated with the kind of feel-bad factor of slow GDP growth. Then [you could] also link it to a revival of social democracy for the United States. From a progressive political point of view, that’s obviously extremely attractive.
  • there’s also a deeper view: that climate change is the situation within which all other politics will happen for the next several generations, at least.
  • ever since the 1990s that’s been the logjam on any serious American commitment.
  • When you look at a third of securities tied up in the carbon economy and the evidence for decoupling GDP growth from carbon emissions maybe not being as strong as we’d like, do you think the change that needs to happen is realistic?
  • Tooze: Realistic? No. I mean, depends what you mean by realism. The scale of the challenge requires a boldness of action for which there is no precedent. That’s the only good purpose that the war analogies serve
  • Meyer: In your piece, you write: “Those in the United States who call for a Green New Deal or a Green Marshall Plan are, if anything, understating the scale of what is needed.”
  • Do you think climate action needs to be larger than, say, the U.S. mobilization for World War II?
  • Tooze: Well, less large in absolute terms. Because even the U.S. was spending almost 40 percent of GDP on World War II. And if you’re the Soviet Union, you’re spending 55 to 60 percent in 1940. We don’t need to do anything like that. It needs to be much bigger than the New Deal, which in fiscal-policy terms was really quite trivial.
  • Crucially, what makes it totally unlike the war is that there’s no happy end. There’s no moment where you win and then everything goes back to the way it was before, but just better. That’s a misunderstanding
  • This isn’t crash dieting; this is a permanent change in lifestyle, and we need to love that and we need to live it and we need to own it and we need to reconcile ourselves to the fact that this is for us and for all subsequent generations of humans.
  • It isn’t just the oil and gas majors, because they wouldn’t get you to 30 percent. Exxon isn’t big enough to get you to that kind of percentage. It’s Exxon, and [the major automakers] Daimler and BMW, and the entire carbon-exposed complex.
  • all the really hard choices need to be made by people like China and India and Pakistan and Bangladesh and Indonesia
  • You don’t have that very much in Germany. There isn’t anyone in Germany saying, “Which bit of mid-20th-century history is this most like?,” mercifully. The one analogy that has popped up in Germany is reunification, which I actually think is quite a good one, because that’s still an ongoing problem
  • in the American case, it would be civil rights and Reconstruction, which isn’t a particularly optimistic comparison to draw. It’s an ongoing problem, it’s a deep historic problem, it only happened once, we still haven’t fixed it, and we’re not at peace.
  • Meyer: There’s a kind of shallow view of climate change: that it is something we need to avert or stop. And that’s somewhat true
  • furthermore—and much more fundamentally than any of those things—this isn’t really about America. I mean, America can be an obstacle and get in the way, but none of the really hard choices needs to be made by Americ
  • like Reconstruction or the civil-rights movement, it needs to be something that people take on like a moral commitment, in the same way they take on genocide prevention as a moral commitment
  • problems that we thought we’d fixed, like the Green Revolution and the feeding of the world population, for instance—totally not obvious that those fixes cope with the next 20 years of what’s ahead of us. The food problem that was such an oppressive issue globally in the 1970s may resurge in an absolutely dramatic way.
  • Meyer: Given all that, if Jerome Powell decided that he wanted to intervene on the side of climate action, what could he do? What could the Fed do?
  • Tooze: What I think the Fed should announce is that it enthusiastically supports the idea of a bipartisan infrastructure push focused on the American electrical network, first and foremost, so that we can actually hook up the renewable-generating capacity—which is now eminently, you know, realistic in economic terms. Setting a backstop to a a fiscal-side-led investment push is the obvious thing.
  • It is indeed a highly appropriate response to an environment of extremely low interest rates, and [former Treasury Secretary] Larry Summers & Co. would argue that it might help, as it were, to suck us out of the state of secular stagnation that we’re in.
  • another avenue to go down—for the Fed to take a role in helping develop a classification of green bonds, of green financing, with a view also to rolling out comprehensive demands for disclosure on the part of American firms, for climate risks to be fully declared on balance sheets, and for due recognition to be given to firms that are in the business of proactively preparing themselves for decarbonization.
  • You could, for instance, declare that the Fed views with disfavor the role of several large American banks in continuing to fund coal investment. Some of the carbon-tracking NGOs have done very good work showing and exposing the way in which some of the largest, the most reputable American banks are still in the business of lending to Big Coal. Banking regulation could be tweaked in a way that would produce a tilt against that.
  • the classic role of the Fed is to support government-issued debt. Insofar as the Green New Deal is a government-issued business, the Fed has just an absolutely historical warrant for supporting fiscal action.
  • with regards to the broader economy, the entire federal-government apparatus essentially stood behind the spread of home ownership in the United States and the promotion of suburbanization through the credit system. And kind of what we need is a Fannie Mae and Freddie Mac for the energy transition.
  • if the question is, Is there historical warrant for the financial agencies of government in the United States biasing the property structure in the economy in a certain way?, the answer is emphatically yes—all the way down to the grotesque role of the New Deal financial apparatus in enshrining the racial segregation of the American urban space, with massive effects from the 1930s onward.
  • The idea of neutrality should not even be allowed in the room in this argument. It’s a question of where we want to be biased. If you look at QE, especially in the U.K. and the EU, it was effectively fossil-biased.
  • monetary policy is not neutral with regards to the environment. There’s no safe space here. The only question is whether you’re going to lead in the right way
  • Meyer: Last question. With any of this, is there a role for interested Americans to play if they are not particularly tied to the financial- or monetary-policy elite?
  • Tooze: Support your congressperson in doing exactly what AOC did in the hearings with Powell a couple of weeks ago
  • [Editor’s Note: Representative Alexandria Ocasio-Cortez asked Powell whether inflation and unemployment are still closely connected, as the Fed has long argued.]
  • Applaud, follow with interest, raise questions. That’s exactly what needs to be happening. The politicization of monetary policy is a fact.
  • If we don’t raise these questions, the de facto politics is, more often than not, conservative and status quo–oriented. So this, like any other area, is one where citizens—whether they’re educated and informed or not—need to wise up, get involved, and follow the arguments and develop positions.
  • So applaud your congresspeople when they do exactly what AOC was doing in that situation. In many ways, I thought it was one of the most hopeful scenes I’ve seen in that kind of hearing in a long time.

Germany Runs Up Against the Limits of Renewables - MIT Technology Review - 0 views

  • At one point this month renewable energy sources briefly supplied close to 90 percent of the power on Germany’s electric grid
  • Germany is giving the rest of the world a lesson in just how much can go wrong when you try to reduce carbon emissions solely by installing lots of wind and solar.
  • Germany’s carbon emissions rose slightly in 2015, largely because the country produces much more electricity than it needs.
  • ...9 more annotations...
  • even if there are times when renewables can supply nearly all of the electricity on the grid, the variability of those sources forces Germany to keep other power plants running. And in Germany, which is phasing out its nuclear plants, those other plants primarily burn dirty coal.
  • Now the government is about to reboot its energy strategy, known as the Energiewende. It was launched in 2010 in hopes of dramatically increasing the share of the country’s electricity that comes from renewable energy and slashing the country’s overall carbon emissions to 40 percent below 1990 levels by 2020 (see “The Great German Energy Experiment”
  • Because German law requires renewable energy to be used first on the German grid, when Germany exports excess electricity to its European neighbors it primarily comes from coal plants.
  • Some aspects of the Energiewende have been successful: renewable sources accounted for nearly one-third of the electricity consumed in Germany in 2015. The country is now the world’s largest solar market. Germany’s carbon emissions in 2014 were 27 percent lower than 1990 levels.
  • Instead of subsidizing any electricity produced by solar or wind power, the government will set up an auction system. Power producers will bid to build renewable energy projects up to a capacity level set by the government, and the resulting prices paid for power from those plants will be set by the market, rather than government fiat.
  • It might seem like an easy way to solve the oversupply issue would be to shut down excess power plants, especially ones that burn coal. But not only are the coal plants used to even out periods when wind and solar aren’t available, they’re also lucrative and thus politically hard to shut down.
  • Because fossil-fuel power plants cannot easily ramp down generation in response to excess supply on the grid, on sunny, windy days there is sometimes so much power in the system that the price goes negative—in other words, operators of large plants, most of which run on coal or natural gas, must pay commercial customers to consume electricity
  • Putting a steep price on carbon emissions would hasten the shutdown of German coal plants. But Europe’s Emissions Trading Scheme, designed to establish a continentwide market for trading permits for carbon emissions, has been a bust. Prices for the permits are so low that there is little incentive for power producers to shut down dirty plants.
  • Also helpful would be a Europewide “supergrid” that would enable renewable power to be easily transported across borders, reducing the need for reliable, always-on fossil fuel plants to supplement intermittent electricity from solar and wind.

Green Energy's Future Rests on Red State Buy-In - The Atlantic - 0 views

  • The states that are most deeply integrated into the existing fossil-fuel economy, either as producers or as consumers, tend also to be the places that are most resistant to, and separated from, the major demographic, cultural, and economic changes remaking 21st-century American life.
  • These fossil-fuel-reliant states are nearly all among those moving most aggressively to restrict voting, abortion, and LGBTQ rights; to ban books; and to censor what teachers and college professors can say about race, gender, and sexual orientation
  • Most of them have larger populations of white voters who identify as Christian and rely heavily on blue-collar work in the powerhouse industries of the 20th century: production of energy and other natural resources, manufacturing, and agriculture. Republicans dominate their electoral landscape, both in state and federal offices.
  • ...15 more annotations...
  • This convergence of fossil-fuel dependence, cultural conservatism, and isolation from the most dynamic modern industries captures how comprehensively the two parties are divided by their exposure to, and attitudes about, the changes reshaping America.
  • The irony is that the energy transition may represent the best chance for the states most reliant on fossil fuels to benefit from the new sources of economic growth.
  • Last year Walter co-wrote a detailed study on how a shift away from fossil fuels would affect the states. Replacing fossil fuels with lower-carbon energy sources, she said, will create “a tremendous amount of jobs in Republican states.”
  • The 19 states that top the EIA’s latest rankings—for the most carbon emitted per dollar of economic output in 2018—present a singular profile. They begin with Wyoming, West Virginia, Louisiana, North Dakota, and Alaska at the top of the list and then extend across the South (including Mississippi, Alabama, Arkansas, and Texas), the heartland (including Indiana, Iowa, Kentucky, Missouri, Ohio, Oklahoma, Kansas, and Nebraska), and the Mountain West (Montana, New Mexico)
  • The political leadership in these states has opposed most efforts to accelerate the transition away from fossil fuels to clean energy sources. Fourteen of these states, for instance, have joined in a lawsuit (led by West Virginia) now before the Supreme Court that could undercut the Environmental Protection Agency’s ability to regulate carbon emissions.
  • The Republican senators from these states have also uniformly opposed proposals to limit carbon emissions, such as a clean-electricity standard to phase out carbon-emitting electricity.
  • The most important exception to this pattern is that many congressional Republicans have backed tax credits to encourage deployment of wind and solar power.
  • all Senate Republicans are opposing the Build Back Better Act’s more sweeping incentives, which energy analysts agree could enormously accelerate the development of those sources.
  • Almost all of the states fighting the energy transition are expressing equally intense resistance to social change. In effect, they are fighting the future on both fronts.
  • The core problem for these states, Muro notes, is that most of them tend to lack the well-educated workers who are, in essence, the crucial raw material for not only internet, computing, and communications firms but also advanced manufacturing.
  • the torrent of culturally conservative legislation across the fossil-fuel-reliant states (and GOP-controlled states more broadly) adds another barrier to tech companies pursuing significant expansions in them. “They want to decentralize somewhat, but they are very concerned about how this plays with the people they are trying to hire,” Muro says. Companies, he adds, “need to make sure the talent is not put off” by these restrictive social policies.
  • Devashree Saha, a senior associate at the World Resources Institute, told me most economic models project that, overall, the transition from a fossil-fuel to a clean-energy economy will create more jobs than it destroys in energy-related sectors.
  • The bipartisan infrastructure bill that Biden signed last year included several provisions designed to channel jobs in the clean-energy economy toward places that would be hurt by diminished reliance on fossil fuels, such as coal communities. The now-stalled Build Back Better plan contains further incentives to steer that investment, though those haven’t been sufficient to overcome the opposition from Republicans representing the fossil-fuel states, or Manchin.
  • That resistance underscores the extent to which the energy transition has been woven into the larger struggle over the country’s direction between what I’ve called the Democrats’ “coalition of transformation” and the competing Republican “coalition of restoration.”
  • The loud demands for more domestic oil and gas drilling since Russia invaded Ukraine, and the fierce opposition to any regulation of carbon emissions, show how a low-carbon future has become just another count in the indictment Republicans use to convince their voters that Democrats want to uproot America from its deepest traditions and transform it into something unrecognizable

What Does Sustainable Living Look Like? Maybe Like Uruguay - The New York Times - 0 views

  • your carbon bill is world-historically anomalous but normal among your neighbors: 17 tons for transportation, 14 tons for housing, eight tons for food, six tons for services, five tons for goods.
  • That household total, 50 tons, represents a carbon footprint of about 25 tons per person. It’s a figure that eclipses the global median by a factor of five and is nowhere close to where it needs to be if you — we — want to stave off the worst of warming’s effects: around two tons per person.
  • This is the problem with any climate policy, big or small: It requires an imaginative leap. While the math of decarbonization and electric mobilization is clear, the future lifestyle it implies isn’t always
  • ...36 more annotations...
  • This isn’t an American crisis alone. All around the world, developed nations have locked themselves into unsustainable, energy-intensive lifestyles.
  • Among those with the largest footprints are wealthy oil-producing microstates with small populations, like Qatar or Trinidad and Tobago, where the per-capita footprint pushes 60 tons
  • In the next tier, with the United States, are other sprawling, continent-size countries that use a lot of heating or cooling and where people tend to drive long distances, such as Canada and Australia (around 20 tons)
  • By dint of their density and reliance on mass transit, nations in Western Europe (as well as Japan and South Korea) make up most of the next tier, which cleaves roughly into two groups: places like Germany, Norway and the Netherlands that rely more on fossil fuels (around 15 tons),
  • places like the United Kingdom, Denmark and France that use a higher percentage of nuclear and renewable power. Though it’s half the size of an American’s, the footprint of someone in the typical French household still remains unsustainably high: around nine tons.
  • This is the paradox at the heart of climate change: We’ve burned far too many fossil fuels to go on living as we have, but we’ve also never learned to live well without them
  • the problem of the future is how to create a 19th-century carbon footprint without backsliding into a 19th-century standard of living. N
  • The greatest crisis in human history may require imagining ways of living — not just of energy production but of daily habit — that we have never seen before. How do we begin to imagine such a household?
  • With a carbon footprint hovering around the global median of 4.5 tons per capita, it falls within a narrow tier of nearly developed countries within sight of two tons per capita — the estimated amount needed to limit the world to 1.5 degrees Celsius of warming.
  • There are countries more prosperous, and countries with a smaller carbon footprint, but perhaps in none do the overlapping possibilities of living well and living without ruin show as much promise as in Uruguay.
  • Mujica harbored another deeper belief too. For years, he had been arguing that the “blind obsession to achieve growth with consumption” was the real cause of the linked energy and ecological crises.
  • In speeches, he pushed his people to reject materialism and embrace Uruguay’s traditions of simplicity and humility. “The culture of the West is a lie,” he told me. “The engine is accumulation. But we can’t pretend that the whole world can embrace it. We would need two or three more planets.”
  • He shared his own experience in solitary confinement, and how years without books or conversation drew him closer to the fundamentals of being: nature, love, family. “I learned to give value to little things in life. I kept some frogs as pets in prison and bathed them with my drinking water,”
  • “The true revolution is a different culture: learning to live with less waste and more time to enjoy freedom.”
  • By 2016, an array of biomass, solar and some 50 wind parks had replaced the grid’s use of oil, helping slash more than half a billion dollars from the country’s annual budget. Today, Uruguay boasts one of the world’s greenest grids, powered by 98 percent renewable energy.
  • prevailing economic conditions and something in Uruguay’s character had afforded the transition more receptivity than anyone predicted. This was one way in which a career in theoretical physics prepared Méndez for the world of policymaking, he said: “You have to be open to the solutions being very narrow and technical, or very wide and human.”
  • as the energy sector shifted, the mind-set in the country began to shift with it, Méndez said, sometimes in surprising ways. Some bought air-conditioning units, but many kept to their formerly low-consumption habits, continuing to hang their laundry and take the bus, dozens of which in Montevideo were now electric. Others bought plug-in timers to automate their laundries to run at night or installed solar water heaters on their roof
  • for Méndez, the biggest shift was among leaders. In cabinet and business meetings the problems of the future — like how to eliminate industrial waste and phase out gas entirely — began to feel like just that, he said: problems, not crises.
  • there appeared to be fundamental tension in how to bring Uruguayans along in the energy transition. On the one hand, the infrastructure shift needed to happen in the background, so the public never lost confidence in the grid — that part had been surprisingly smooth. But on the other hand, it was important to keep people engaged so they would support the necessary changes to come
  • Emaldi and her colleagues focused their efforts on electrifying transportation and growing the green-energy sector. The government eliminated duties and taxes on electric cars and rebranded a tax on gas as a CO2 tax, with a portion funding green initiatives.
  • “What comes in the near future will change more lives,” Minister Paganini told me. “You have to get into sectors or areas that are much more difficult than just changing the generation of electricity.” You need to change human behavior.
  • fossil fuels gave humanity the ability to choose our food, to transform a rainforest or windblown desert into something fertile and constant, a biotic vending machine from which eaters can select whatever they want whenever they want it. This choice now drives about a third of all global emissions. Most of them stem from the growing process itself — clearing land, fertilizing crops — with the bulk of the rest coming indirectly from the vast web of manufacturing and delivery systems that bring it to us: packaging crackers, refrigerating drumsticks, airlifting avocados.
  • One reason the global cattle industry had become so damaging, Baethgen said, was that too many grasslands had been razed or degraded. In the short term, feedlots produced more food, often with lower emissions, since cows got fatter faster and burped less frequently, but over the long term, without the grasslands to recycle carbon, net emissions built up. From Baethgen’s perspective, every damaged field thus represented a huge opportunity: By restoring grasslands, he could not only pull more greenhouse gases into the ground, but also grow more beef. And since the 1990s, Uruguay has managed a remarkable feat: increasing its annual production of beef without any increase in greenhouse gases — and doing all of this on natural pasturelands.
  • He believed too much climate science relied on big-picture modeling to drive engagement. “Those science-fiction scenarios were great to increase awareness,” he said. “But if you give a minister of agriculture information for the year 2080, that doesn’t do anything.” He waved a hand over the landscape. “You’re providing information, far in the future, with no resolution and no certainty. That’s the best combination to ensure paralysis. Nobody does anything.”
  • In his 2016 book, “The Great Derangement,” the Indian writer Amitav Ghosh says it’s unwise to reduce climate denial to “only a function of money and manipulation.” The sheer level of paralysis, he writes, “suggests that the climate crisis threatens to unravel something deeper, without which large numbers of the people would be at a loss to find meaning.” Ghosh wonders if the modern consumer mind-set can ever change, collectively or otherwise: “In a world where the rewards of a carbon-intensive economy are regarded as wealth, this must be reckoned as a very significant material sacrifice.”
  • Esponda described his family as middle to upper middle class. Both he and Laroca were economists for the city and together made about $30,000 a year. “Everybody in Uruguay is middle class,” he said. I thought I knew what he meant. Unlike in the United States, I found it difficult in Uruguay to discern class differences.

In stark contrast to most American homes with two kids, their apartment wasn’t overflowing with toys. Two bikes leaned against the wall by a plastic slide. “Our choices don’t really have anything to do with the environment,” he said. “It’s about saving money, yes, but also being careful with what we buy.”

  • We often picture the future as a kind of growth, a set of possibilities to expand and realize, but maybe it could also be the opposite, a present to reconcile and safeguard.
  • Part of the reason America has become so paralyzed by climate change is precisely that we’ve failed to acknowledge the limits it imposes — on where we can live, the things we can have, the household we can envision.

ChatGPT AI Emits Metric Tons of Carbon, Stanford Report Says - 0 views

  • A new report released today by the Stanford Institute for Human-Centered Artificial Intelligence estimates the amount of energy needed to train AI models like OpenAI’s GPT-3, which powers the world-famous ChatGPT, could power an average American’s home for hundreds of years. Of the three AI models reviewed in the research, OpenAI’s system was by far the most energy-hungry.
  • OpenAI’s model reportedly released 502 metric tons of carbon during its training. To put that in perspective, that’s 1.4 times more carbon than Gopher and a whopping 20.1 times more than BLOOM. GPT-3 also required the most power consumption of the lot at 1,287 MWh.
  • “If we’re just scaling without any regard to the environmental impacts, we can get ourselves into a situation where we are doing more harm than good with machine learning models,” Stanford researcher ​​Peter Henderson said last year. “We really want to mitigate that as much as possible and bring net social good.”

  • If all of this sounds familiar, it’s because we basically saw this same environmental dynamic play out several years ago with tech’s last big obsession: Crypto and web3. In that case, Bitcoin emerged as the industry’s obvious environmental sore spot due to the vast amounts of energy needed to mine coins in its proof of work model. Some estimates suggest Bitocin alone requires more energy every year than Norway’s annual electricity consumption.
  • rs of criticism from environmental activists however led the crypto industry to make some changes. Ethereum, the second largest currency on the blockchain, officially switched last year to a proof of stake model which supporters claim could reduce its power usage by over 99%. Other smaller coins similarly were designed with energy efficiency in mind. In the grand scheme of things, large language models are still in their infancy and it’s far from certain how its environmental report card will play out.

At Ice Age End, a Smaller Gap in Warming and Carbon Dioxide - NYTimes.com - 0 views

  • Previous research had suggested that as the world began to emerge from the depths of the ice age more than 20,000 years ago, warming in Antarctica preceded changes in the global carbon dioxide level by something like 800 years.
  • Jeremy Shakun, a visiting scholar at Harvard, compiled a temperature record for the whole planet, not just Antarctica. He concluded that the carbon dioxide increase preceded the overall planetary warming.
  • A small gap poses no conceptual problems, scientists said. They have long known that the ice ages are caused by variations in the earth’s orbit around the sun. When an intensification of sunlight initiates the end of an ice age, they believe, carbon dioxide is somehow flushed out of the ocean, causing a big amplification of the initial warming.

Pilot Plant in the Works for Carbon Dioxide Cleansing - NYTimes.com - 0 views

  • “There is a lot of speculation of how much it will actually cost,” he said, with estimates from $20 a ton to as much as $2,000. “We won’t know for sure until someone builds a pilot plant.” (An average passenger vehicle generates about five tons of carbon dioxide a year.)
  • Dr. Keith says he thinks it may be possible to lower the cost of capture toward $100 a ton as the company grows.
  • Gas capture would be extremely important in developing a rational price for carbon emissions, said Dr. Fox of the British mechanical engineering society. “Whatever it costs to take it out of the air and store it away,” Dr. Fox said, “that’s the price polluters would pay if they want to put carbon into the air.”

Naomi Klein: How science is telling us all to revolt - 0 views

  • Serious scientific gatherings don’t usually feature calls for mass political resistance, much less direct action and sabotage. But then again, Werner wasn’t exactly calling for those things. He was merely observing that mass uprisings of people – along the lines of the abolition movement, the civil rights movement or Occupy Wall Street – represent the likeliest source of “friction” to slow down an economic machine that is careening out of control. We know that past social movements have “had tremendous influence on . . . how the dominant culture evolved”, he pointed out. So it stands to reason that, “if we’re thinking about the future of the earth, and the future of our coupling to the environment, we have to include resistance as part of that dynamics”. And that, Werner argued, is not a matter of opinion, but “really a geophysics problem”.
  • in November 2012, Nature published a commentary by the financier and environmental philanthropist Jeremy Grantham urging scientists to join this tradition and “be arrested if necessary”, because climate change “is not only the crisis of your lives – it is also the crisis of our species’ existence”.
  • what Werner is doing with his modelling is different. He isn’t saying that his research drove him to take action to stop a particular policy; he is saying that his research shows that our entire economic paradigm is a threat to ecological stability. And indeed that challenging this economic paradigm – through mass-movement counter-pressure – is humanity’s best shot at avoiding catastrophe.

  • for any closet revolutionary who has ever dreamed of overthrowing the present economic order in favour of one a little less likely to cause Italian pensioners to hang themselves in their homes, this work should be of particular interest. Because it makes the ditching of that cruel system in favour of something new (and perhaps, with lots of work, better) no longer a matter of mere ideological preference but rather one of species-wide existential necessity.
  • Anderson points out that we have lost so much time to political stalling and weak climate policies – all while global consumption (and emissions) ballooned – that we are now facing cuts so drastic that they challenge the fundamental logic of prioritising GDP growth above all else.
  • Anderson and Bows argue that, if the governments of developed countries are serious about hitting the agreed upon international target of keeping warming below 2° Celsius, and if reductions are to respect any kind of equity principle (basically that the countries that have been spewing carbon for the better part of two centuries need to cut before the countries where more than a billion people still don’t have electricity), then the reductions need to be a lot deeper, and they need to come a lot sooner.
  • To have even a 50/50 chance of hitting the 2° target (which, they and many others warn, already involves facing an array of hugely damaging climate impacts), the industrialised countries need to start cutting their greenhouse-gas emissions by something like 10 per cent a year – and they need to start right now.
  • a 10 per cent drop in emissions, year after year, is virtually unprecedented since we started powering our economies with coal. In fact, cuts above 1 per cent per year “have historically been associated only with economic recession or upheaval”, as the economist Nicholas Stern put it in his 2006 report for the British government.
  • Only in the immediate aftermath of the great market crash of 1929 did the United States, for instance, see emissions drop for several consecutive years by more than 10 per cent annually, according to historical data from the Carbon Dioxide Information Analysis Centre
  • If we are to avoid that kind of carnage while meeting our science-based emissions targets, carbon reduction must be managed carefully through what Anderson and Bows describe as “radical and immediate de-growth strategies in the US, EU and other wealthy nations”. Which is fine, except that we happen to have an economic system that fetishises GDP growth above all else, regardless of the human or ecological consequences, and in which the neoliberal political class has utterly abdicated its responsibility to manage anything (since the market is the invisible genius to which everything must be entrusted).
  • in order to appear reasonable within neoliberal economic circles, scientists have been dramatically soft-peddling the implications of their research. By August 2013, Anderson was willing to be even more blunt, writing that the boat had sailed on gradual change. “Perhaps at the time of the 1992 Earth Summit, or even at the turn of the millennium, 2°C levels of mitigation could have been achieved through significant evolutionary changes within the political and economic hegemony. But climate change is a cumulative issue! Now, in 2013, we in high-emitting (post-)industrial nations face a very different prospect. Our ongoing and collective carbon profligacy has squandered any opportunity for the ‘evolutionary change’ afforded by our earlier (and larger) 2°C carbon budget. Today, after two decades of bluff and lies, the remaining 2°C budget demands revolutionary change to the political and economic hegemony” (his emphasis).
  • there are many people who are well aware of the revolutionary nature of climate science. It’s why some of the governments that decided to chuck their climate commitments in favour of digging up more carbon have had to find ever more thuggish ways to silence and intimidate their nations’ scientists
  • If you want to know where this leads, check out what’s happening in Canada, where I live. The Conservative government of Stephen Harper has done such an effective job of gagging scientists and shutting down critical research projects that, in July 2012, a couple thousand scientists and supporters held a mock-funeral on Parliament Hill in Ottawa, mourning “the death of evidence”. Their placards said, “No Science, No Evidence, No Truth”.

  • Bubbles of ancient air trapped by glaciers and ice sheets have been tested, and they show that over the past 800,000 years, the amount of carbon dioxide in the air oscillated between roughly 200 and 300 parts per million. Just before the Industrial Revolution, the level was about 280 parts per million and had been there for several thousand years.
  • carbon dioxide as the master control knob of the earth’s climate. He said that because the wobbles in the earth’s orbit were not, by themselves, big enough to cause the large changes of the ice ages, the situation made sense only when the amplification from carbon dioxide was factored in.
  • ...6 more annotations...
  • The gas seemingly played a major role in amplifying the effects of the ice ages, which were caused by wobbles in the earth’s orbit. The geologic record suggests that as the earth began cooling, the amount of carbon dioxide fell, probably because much of it got locked up in the ocean, and that fall amplified the initial cooling. Conversely, when the orbital wobble caused the earth to begin warming, a great deal of carbon dioxide escaped from the ocean, amplifying the warming.
  • Their best estimate is that if the amount of carbon dioxide doubles, the temperature of the earth will rise about five or six degrees Fahrenheit. While that may sound small given the daily and seasonal variations in the weather, the number represents an annual global average, and therefore an immense addition of heat to the planet.
  • Moreover, scientists say that an increase of five or six degrees is a mildly optimistic outlook. They cannot rule out an increase as high as 18 degrees Fahrenheit, which would transform the planet.
  • Among the most prominent of these contrarians is Richard Lindzen of the Massachusetts Institute of Technology, who contends that as the earth initially warms, cloud patterns will shift in a way that should help to limit the heat buildup. Most climate scientists contend that little evidence supports this view,
  • China’s citizens, on average, still use less than a third of the energy per person as Americans. But with 1.3 billion people, four times as many as the United States, China is so large and is growing so quickly that it has surpassed the United States to become the world’s largest overall user of energy.
  • “When I go see things with my children, I let them know they might not be around when they’re older,” he said. “ ‘Go enjoy these beautiful forests before they disappear. Go enjoy the glaciers in these parks because they won’t be around.’ It’s basically taking note of what we have, and appreciating it, and saying goodbye to it.”

  • it is our great collective misfortune that the scientific community made its decisive diagnosis of the climate threat at the precise moment when those elites were enjoying more unfettered political, cultural, and intellectual power than at any point since the 1920s.
  • Very little, however, has been written about how market fundamentalism has, from the very first moments, systematically sabotaged our collective response to climate change.
  • The core problem was that the stranglehold that market logic secured over public life in this period made the most direct and obvious climate responses seem politically heretical
  • How, for instance, could societies invest massively in zero-carbon public services and infrastructure at a time when the public sphere was being systematically dismantled and auctioned off
  • How could governments heavily regulate, tax, and penalise fossil fuel companies when all such measures were being dismissed as relics of “command and control” communism?
  • And how could the renewable energy sector receive the supports and protections it needed to replace fossil fuels when “protectionism” had been made a dirty word?
  • With hindsight, it’s hard to see how it could have turned out otherwise. The twin signatures of this era have been the mass export of products across vast distances (relentlessly burning carbon all the way), and the import of a uniquely wasteful model of production, consumption, and agriculture to every corner of the world (also based on the profligate burning of fossil fuels)
  • Because of those decades of hardcore emitting, exactly when we were supposed to be cutting back, the things we must do to avoid catastrophic warming are no longer just in conflict with the particular strain of deregulated capitalism that triumphed in the 1980s. They are now in conflict with the fundamental imperative at the heart of our economic model: grow or die.
  • so much carbon has been allowed to accumulate in the atmosphere over the past two decades that now our only hope of keeping warming below the internationally agreed-upon target of 2C is for wealthy countries to cut their emissions by somewhere in the neighbourhood of eight to 10% a year. The “free” market simply cannot accomplish this task. Indeed, this level of emission reduction has happened only in the context of economic collapse or deep depressions.
  • our economy is at war with many forms of life on earth, including human life. What the climate needs to avoid collapse is a contraction in humanity’s use of resources; what our economic model demands to avoid collapse is unfettered expansion. Only one of these sets of rules can be changed, and it’s not the laws of nature.
  • , it is eminently possible to transform our economy so that it is less resource-intensive, and to do it in ways that are equitable, with the most vulnerable protected and the most responsible bearing the bulk of the burden. Low-carbon sectors of our economies can be encouraged to expand and create jobs, while high-carbon sectors are encouraged to contract. The problem, however, is that this scale of economic planning and management is entirely outside the boundaries of our reigning ideology. The only kind of contraction our current system can manage is a brutal crash, in which the most vulnerable will suffer most of all.
  • So we are left with a stark choice: allow climate disruption to change everything about our world, or change pretty much everything about our economy to avoid that fate. But we need to be very clear: because of our decades of collective denial, no gradual, incremental options are now available to us. Gentle tweaks to the status quo stopped being a climate option when we supersized the American Dream in the 1990s, and then proceeded to take it global

  • Climate change presents a profound challenge to this cautious centrism because half measures won’t cut it: “all of the above energy” program, as US president Barack Obama describes his approach, has about as much chance of success as an all-of-the-above diet, and the firm deadlines imposed by science require that we get very worked up indeed.
  • we need to think differently, radically differently, for those changes to be remotely possible. A worldview will need to rise to the fore that sees nature, other nations, and our own neighbours not as adversaries, but rather as partners in a grand project of mutual reinvention.
  • That’s a big ask. But it gets bigger. Because of our endless procrastination, we also have to pull off this massive transformation without delay. The International Energy Agency (IEA) warns that if we do not get our emissions under control by a rather terrifying 2017, our fossil fuel economy will “lock-in” extremely dangerous warming.
  • “The door to reach two degrees is about to close. In 2017 it will be closed forever.” In short, we have reached what some activists have started calling “Decade Zero” of the climate crisis: we either change now or we lose our chance
