In just a few hours, the plane’s instruments identified six sites with unusually high methane emissions

Methane is loosely regulated, difficult to detect and rising sharply

Operators of the sites identified by The Times are among the very companies that have lobbied the Trump administration,

either directly or through trade organizations, to weaken regulations on methane,

Next year, the administration could move forward with a plan that would effectively eliminate requirements

By the E.P.A.’s own calculations, the rollback would increase methane emissions by 370,000 tons through 2025, enough to power more than a million homes for a year.

“This site’s definitely leaking,”

The reporters drove to the sites armed with infrared video gear that revealed methane billowing from tanks, seeping from pipes and wafting from bright flares that are designed to burn off the gas,

The regulatory rollback sought by the energy industry is the latest chapter in the administration’s historic effort to weaken environmental and climate regulations while waging a broad-based attack on climate science.

The findings address the mystery behind rising levels of methane in the atmosphere. Methane levels have soared since 2007 for reasons that still aren’t fully understood.

Methane also contributes to ground-level ozone, which, if inhaled, can cause asthma and other health problems.

In the course of about four hours of flying, we found at least six sites with high methane-emissions readings, ranging from about 300 pounds to almost 1,100 pounds an hour, including at DCP Pegasus, which is part owned by the energy giant Phillips 66.

At the DCP Pegasus plant, south of Midland, the camera transformed a tranquil scene into a furnace. Hot columns of gas shot into the air. Fumes engulfed structures.

A worker went to check on the tank, climbing some stairs and walking into the plume.

The companies found an administration willing to listen.

Before his appointment to the post of assistant administrator at the E.P.A.

The largest previous assessment of methane emissions from oil and gas in the United States, published in 2018, reviewed studies covering about 1,000 well sites, a tiny fraction of the more than one million active wells in the country. The new study, by contrast, used aerial data to examine nearly 27,000 sites from above: more than 90 percent of all wells in the New Mexico portion of the Permian Basin, which also extends into Texas.

estimated about a decade ago that the break-even point — the point above which natural gas would actually hurt the climate more than coal — was a 3.1 percent methane leakage rate. Based on more recent data from the Intergovernmental Panel on Climate Change, Dr. Howarth estimates that the threshold is closer to 2.8 or 2.9 percent.That makes the 9.4 percent leakage rate in the new study highly alarming,

Methane can be released by wells both on purpose, in a process known as venting, and through unintentional leaks from aging or faulty equipment.

Natural gas accounts for about a third of American energy consumption, and because it is less costly than coal in terms of carbon dioxide emissions, many policymakers have promoted it as a “bridge” that could do less damage to the climate while society works on a longer-term transition to renewable energy. But compared to coal, natural gas results in much higher emissions of methane, which is a more potent greenhouse gas than carbon dioxide, but doesn’t last as long in the atmosphere.

They found that a small number of wells and pipelines accounted for “the vast majority” of methane leaks, Ms. Chen said, adding, “Comprehensive point source surveys find more high-consequence emission events, which drive total emissions.”

If there was good news in the study, it was that a small number of oil and gas sites contributed disproportionately to emissions — suggesting that, if the worst offenders change their practices, it is possible for the industry to operate more cleanly.

The Stanford researchers emphasized that the same methodology they used to quantify methane emissions could be used to identify problem sites and target regulations accordingly.“Aerial technology found high methane emissions,” Ms. Chen said, “but can also help fix them cost effectively.”

An E.P.A. spokeswoman, Enesta Jones, said the agency was “always working to improve and build on” ways to track emissions.The new analysis also shows how, as oil and gas giants start a long-awaited shift away from fossil fuels, they are shedding some of their most polluting assets to companies that provide almost no transparency into their operations.

According to the new analysis, Hilcorp, which has grown by buying up decades-old oil and gas assets, has the highest methane emissions in the country, despite being the 13th-largest gas producer. Hilcorp’s methane emissions intensity, or leak rate, was almost six times higher than the average of the top 30 producers, largely caused by high emissions from its aging San Juan operations.

Firms like Terra aimed to make quick money by buying up oil and gas production sites, ramping up production and selling them off for a neat profit. But these ventures have struggled as a production glut caused natural gas prices to slump. The Covid-19 pandemic threw the industry into further disarray.

To be sure, the large producers remain huge emitters. For greenhouse gas emissions overall, Exxon Mobil reported the industry’s highest numbers in 2019, a record that is expected to become a top priority as the company contends with three climate-focused directors recently elected to its board by shareholders increasingly wary of its exposure to climate risks. Many of the oil and gas giants have joined voluntary, industrywide initiatives to reduce emissio

Under the Congressional Review Act, any regulation finalized within 60 legislative days of the end of a presidential term can be overturned with a simple majority vote in the Senate.

The most significant of those would be the rules on methane, which were published by the Environmental Protection Agency. While most climate change regulations target carbon dioxide, the most damaging greenhouse gas, methane is a close second, lingering in the atmosphere for a shorter period of time but packing a bigger punch while it lasts. By some estimates, methane has 80 times the heat-trapping power of carbon dioxide in the first 20 years in the atmosphere.

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."

They were able to reverse engineer the ancient climate by analyzing temperature-sensitive structures of lipids produced by fossil bacteria and archaea living in these bygone wetlands, and preserved for all time in the coal. The team found that, under this past regime of high CO2, in the ancient U.K., Germany, and New Zealand, life endured mean annual temperatures of 23–29 degrees Celsius (73–84 degrees Fahrenheit) or 10–15 degrees Celsius (18–27 degrees Fahrenheit) warmer than modern times.

“These wetlands looked exactly how only tropical wetlands look at present, like the Everglades or the Amazon,” Naafs says. “So Europe would look like the Everglades and a heat wave like we’re currently experiencing in Europe would be completely normal. That is, it would be the everyday climate.”

But over 50 million years ago this would have been the baseline from about 45 to 60 degrees latitude. Under this broiling regime, with unprecedented heat as the norm, actual heat waves might have begun to take on an unearthly quality.

closer to the equator in this global sweat lodge, the heat might have been even more outrageous, shattering the limits of complex life. To see exactly how hot, Naafs’ team also analyzed ancient lignite samples from India, which would have been in the tropics at the time—that subcontinent still drifting across the Indian Ocean toward its eventual mountain-raising rendezvous with Asia. But unfortunately, the temperatures from these samples were maxed out. That is, they were too hot for his team to measure by the new methods they had developed.

“Some climate models suggest that the tropics just became a dead zone with temperatures over 50 degrees Celsius (122 degrees Fahrenheit) like in Africa and South America,” says Naafs. “But we have no data so we don’t know.”

“Basically every type of paleoclimate research that’s being done shows that high CO2 means that it’s very warm. And when it gets very warm, it can be really, really, really warm.

“You start really looking into them and you go, ‘Wow. We are dealing with a rainforest.’”

“You’ve got alligators, giant tortoises, primates, things like that. We have these big hippo-like animals called Coryphodon. You have tapirs—so you’ve got tapirs living pretty close to the North Pole in the early Eocene, which today—clearly tapirs are not at the North Pole,” she says, laughing.

One obvious way to reconcile this disparity is by noticing that the changes to the ancient earth took place over hundreds-of-thousands to millions of years and (IPCC graphs notwithstanding) that time won’t stop at the end of the 21st century. The changes that we’ve already set in motion, unless we act rapidly to countervail them, will similarly take millennia to fully unfold

we’re clearly not content to stop at just 400 ppm. If we do, in fact, push CO2 up to around 1,000 ppm by the end of the century, the warming will persist and the earth will continue to change for what, to humans, is a practical eternity

Most worryingly, the climate models that we depend on as a species to predict our future have largely failed to predict our sultry ancient past.

we know methane can actually amplify high-latitude warming, so maybe that’s some of the missing feedback.

Though there are no trees here at the top of the world, there are tree stumps. And they are around 50 million years old.

Clearly we are missing something, and Naafs thinks that one of the missing ingredients in the models is methane, a powerful greenhouse gas which might help close the divide between model worlds and fossil worlds.

We know tropical wetlands pump much more methane into the atmosphere compared to [cooler] wetlands.

The last time CO2 was at 400 ppm (as it is today) was 3 million years ago during the Pliocene epoch, when sea levels were perhaps 80 feet higher than today.

Naafs thinks that many of the wildest features of the early age of mammals could be recreated.

That division came to a head earlier this year when the Trump Administration rolled back rules requiring oil and gas companies to halt methane emissions, the second-most common greenhouse gas.

API blasted out emails to reporters highlighting the role natural gas has played reducing emissions, praising the launch of a Senate climate group looking into potential bipartisan climate solutions, and saying that when it comes to climate change “we’re on it.”

A handful of oil majors, BP, ConocoPhilips, ExxonMobil, Shell and Total, are supporting a coalition pushing a proposal for a carbon tax at the federal level that would distribute the revenue back to taxpayers.

“Companies should not be so greedy,” he said, calling addressing emissions from methane an “asset protection strategy.”

Denying climate change is no longer viable, but trade groups often end up supporting the policy views of their lowest common denominator.

energy systems around the world need to shift dramatically to keep temperatures from rising more than 1.5°C by the end of the century,

Massachusetts Senator Elizabeth Warren and Vermont Senator Bernie Sanders, who are polling alongside former Vice President Joe Biden in a close race for the Democratic presidential nomination, have both said they would ban fracking as part of a suite of policies targeting the industry.

President Trump, who regularly claims the climate measures amount to a “war” on American energy.

But the science is also clear that simply not addressing the issue will bring much worse economic catastrophe, from submerged cities to mass migration fueled by extreme weather.

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.

“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.”

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

Planting as many trees as possible would reduce the amount of greenhouse gases in the atmosphere by about nine gigatons each year

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

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

“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.”

Emissions from livestock, largely from burping cows and sheep and their manure, currently make up almost 15% of global emissions. Beef and dairy alone make up 65% of all livestock emissions.

Meat consumption is on track to rise 75% by 2050, and dairy 65%, compared with 40% for cereals. By 2020, China alone is expected to be eating 20m tonnes more of meat and dairy a year.

agricultural emissions will take up the entire world’s carbon budget by 2050, with livestock a major contributor. This would mean every other sector, including energy, industry and transport, would have to be zero carbon, which is described as “impossible”. The Chatham House report concludes: “Dietary change is essential if global warming is not to exceed 2C.”

“This is not a radical vegetarian argument; it is an argument about eating meat in sensible amounts as part of healthy, balanced diets.”

Oil prices dropped from over $100 a barrel in 2014 to just about $35 a barrel today. That's about the same amount it costs to produce a barrel, meaning right now oil producers are making nothing. Natural gas prices are down to their lowest levels in 16 years.

Thanks to new technologies, mostly fracking, which allows producers to extract gas and oil from rocks thousands of feet below the surface of the earth with a mix of high-pressured water and chemicals, production of oil skyrocketed from about 5,000 barrels a day in 2008 to 8,700 in 2014.

On New Year's Eve a Bahamian tanker called the "Theo T" cruised out of Corpus Christi, Texas with the first batch of crude oil to leave US shores in four decades, thanks to the budget bill that enabled it.

The short answer: politics. Without throwing a bone to oil-backed Congresspeople, the budget bill last month would have likely been blocked.

The other problem is leakage: Natural gas has been touted by Obama as a "bridge fuel" to get the world off of coal and other dirtier fuels. But it's only better than coal if the vast majority of it doesn't leak into the atmosphere before being burned.

negate any of its climate benefits,

But it's slightly more clear what oil exports will do: one analysis found exports will allow for 3.3 million more barrels a day of oil to be produced in the US between 2015 and 2035.

"We're already on the frontlines of oil and gas production," Raleigh Hoke, an activist with the Gulf Restoration Network, which works with communities affected by oil and gas in Louisiana, told VICE over the phone. "There are already 28 export facilities being constructed along the coast, so that means countless new pipelines through people's backyards, new trains carrying oil which are dangerous, and it hinders our efforts to restore our wetlands."

"Frankly we just have to wait until November," Athan Manuel, an organizer at the Sierra Club, told VICE. "And then hope we have an anti-fossil fuel Senate and an anti-fossil fuel President."

it faces the same daunting task that confronted Carl Bosch a century ago: How much can it bring costs down? And how fast can it scale up

They believe that over the next seven years they can bring expenses down to a level that would enable them to sell CO₂ into more lucrative markets. Air-captured CO₂ can be combined with hydrogen and then fashioned into any kind of fossil-fuel substitute you want. Instead of making bread from air, you can make fuels from air.

What Gebald and Wurzbacher really want to do is to pull vast amounts of CO₂ out of the atmosphere and bury it, forever, deep underground, and sell that service as an offset

companies like Climeworks face a quandary: How do you sell something that never existed before, something that may never be cheap, into a market that is not yet real?

It’s arguably the case, in fact, that when it comes to reducing our carbon emissions, direct air capture will be seen as an option that’s too expensive and too modest in impact. “The only way that direct air capture becomes meaningful is if we do all the other things we need to do promptly,” Hal Harvey, a California energy analyst who studies climate-friendly technologies and policies, told me

In short, the best way to start making progress toward a decarbonized world is not to rev up millions of air capture machines right now. It’s to stop putting CO₂ in the atmosphere in the first place.

If the nations of the world were to continue on the current track, it would be impossible to meet the objectives of the 2016 Paris Agreement, which set a goal limiting warming to 2 degrees Celsius or, ideally, 1.5 degrees. And it would usher in a world of misery and economic hardship. Already, temperatures in some regions have climbed more than 1 degree Celsius, as a report by the Intergovernmental Panel on Climate Change noted last October. These temperature increases have led to an increase in droughts, heat waves, floods and biodiversity losses and make the chaos of 2 or 3 degrees’ additional warming seem inconceivable

A further problem is that maintaining today’s emissions path for too long runs the risk of doing irreparable damage to the earth’s ecosystems — causing harm that no amount of technological innovation can make right. “There is no reverse gear for natural systems,” Harvey says. “If they go, they go. If we defrost the tundra, it’s game over.” The same might be said for the Greenland and West Antarctic ice sheets, or our coral reefs. Such resources have an asymmetry in their natural architectures: They can take thousands or millions of years to form, but could reach conditions of catastrophic decline in just a few decades.

To have a shot at maintaining a climate suitable for humans, the world’s nations most likely have to reduce CO₂ emissions drastically from the current level — to perhaps 15 billion or 20 billion metric tons per year by 2030; then, through some kind of unprecedented political and industrial effort, we need to bring carbon emissions to zero by around 2050

To preserve a livable environment we may also need to extract CO₂ from the atmosphere. As Wurzbacher put it, “if you take all these numbers from the I.P.C.C., you end up with something like eight to 10 billion tons — gigatons — of CO₂ that need to be removed from the air every year, if we are serious about 1.5 or 2 degrees.

Through photosynthesis, our forests take extraordinary amounts of carbon dioxide from the atmosphere, and if we were to magnify efforts to reforest clear-cut areas — or plant new groves, a process known as afforestation — we could absorb billions more metric tons of carbon in future years.

we could grow crops specifically to absorb CO₂ and then burn them for power generation, with the intention of capturing the power-plant emissions and pumping them underground, a process known as bioenergy with carbon capture and storage, or BECCS

Ever since the Industrial Revolution, human societies have produced an excess of CO₂, by taking carbon stores from deep inside the earth — in the form of coal, oil and gas — and from stores aboveground (mostly wood), then putting it into the atmosphere by burning it. It has become imperative to reverse the process — that is, take CO₂ out of the air and either restore it deep inside the earth or contain it within new surface ecosystems.

“It’s not about saying, ‘I want to plant a tree.’ It’s about saying, ‘We want to plant a billion trees.’

“We have to come to grips with the fact that we waited too long and that we took some options off the table,” Michael Oppenheimer, a Princeton scientist who studies climate and policy, told me. As a result, NETs no longer seem to be just interesting ideas; they look like necessities. And as it happens, the Climeworks machines on the rooftop do the work each year of about 36,000 trees.

air capture could likewise help counter the impact of several vital industries. “There are process emissions that come from producing iron and steel, cement and glass,” she says, “and any time you make these materials, there’s a chemical reaction that emits CO₂.” Direct air capture could even lessen the impacts of the Haber-Bosch processes for making fertilizer; by some estimates, that industry now accounts for 3 percent of all CO₂ emissions.

Wind and solar are now the cheapest forms of energy in the right locations,” Pacala says. “The return on those investments, if you calculated it, would blow the doors off anything in your portfolio. It’s like investing in early Apple. So it’s a spectacular story of success. And direct air capture is precisely the same kind of problem, in which the only barrier is that it’s too costly.”

what all the founders have in common is a belief that the cost of capturing a ton of carbon will soon drop sharply.

M.I.T.’s Howard Herzog, for instance, an engineer who has spent years looking at the potential for these machines, told me that he thinks the costs will remain between $600 and $1,000 per metric ton

He points out that because direct-air-capture machines have to move tremendous amounts of air through a filter or solution to glean a ton of CO₂ — the gas, for all its global impact, makes up only about 0.04 percent of our atmosphere — the process necessitates large expenditures for energy and big equipment. What he has likewise observed, in analyzing similar industries that separate gases, suggests that translating spreadsheet projections for capturing CO₂ into real-world applications will reveal hidden costs. “I think there has been a lot of hype about this, and it’s not going to revolutionize anything,

Climeworks’s current goal is to remove 1 percent of the world’s annual CO₂ emissions by the mid 2020s.

“Basically, we have a road map — $600, down to $400, down to $300 and $200 a ton,” Wurzbacher said. “This is over the next five years. Down to $200 we know quite well what we’re doing.” And beyond $200, Wurzbacher suggested, things get murkier.

To actually capture 1 percent of the world’s carbon emissions by 2025 would, by Gebald’s calculations, require that Climeworks build 250,000 carbon-capture plants like the ones on the roof at Hinwil. That adds up to about 4.5 million carbon collectors

The Climeworks founders therefore try to think of their product as the automotive industry might — a piece of mass-produced technology and metal, not the carbon they hope to sequester.

“Every CO₂ collector has about the same weight and dimensions of a car — roughly two tons, and roughly 2 meters by 2 meters by 2 meters,” Gebald said. “And all the methods used to produce the CO₂ collectors could be well automated. So we have the automotive industry as a model for how to produce things in large quantities for low cost.

n 1954, the economist Paul Samuelson put forward a theory that made a distinction between “private-consumption goods” — bread, cars, houses and the like — and commodities that existed apart from the usual laws of supply and demand.

the other type of commodity Samuelson was describing is something now known as a “public good,” which benefits everyone but is not bought, sold or consumed the same way

direct air capture’s success would be limited to the size of the market for private goods — soda fizz, greenhouse gas — unless governments decided to intervene and help fund the equivalent of several million (or more) lighthouses.

An intervention could take a variety of forms. It could be large grants for research to find better sorbent materials, for instance, which would be similar to government investments that long ago helped nurture the solar- and wind-power industries. But help could also come by expanding regulations that already exist.

The Climeworks founders told me they don’t believe their company will succeed on what they call “climate impact” scales unless the world puts significant prices on emissions, in the form of a carbon tax or carbon fee.

“Our goal is to make it possible to capture CO₂ from the air for below $100 per ton,” Wurzbacher says. “No one owns a crystal ball, but we think — and we’re quite confident — that by something like 2030 we’ll have a global average price on carbon in the range of $100 to $150 a ton.” There is optimism in this thinking

A company that sells a product or uses a process that creates high emissions — an airline, for instance, or a steel maker — could be required to pay carbon-removal companies $100 per metric ton or more to offset their CO₂ output. Or a government might use carbon-tax proceeds to directly pay businesses to collect and bury CO₂.

“It doesn’t cost too much to pump CO₂ underground,” Stanford’s Sally Benson says. Companies already sequester about 34 million metric tons of CO₂ in the ground every year, at a number of sites around the world, usually to enhance the oil-drilling process. “The costs range from $2 to $15 per ton. So the bigger cost in all of this is the cost of carbon capture.”

The weekend before, Gutknecht told me, he received 900 unsolicited inquiries by email. Many were from potential customers who wanted to know how soon Climeworks could bury their CO₂ emissions, or how much a machine might cost them.

A Climeworks app could be installed on my smartphone, he explained. It could then be activated by my handset’s location services. “You fly over here to Europe,” he explained, “and the app tells you that you have just burned 1.7 tons of CO₂. Do you want to remove that? Well, Climeworks can remove it for you. Click here. We’ll charge your credit card.

The vast and constant market demand for fuel is why Carbon Engineering has staked its future on synthetics. The world currently burns about 100 million barrels of oil a day.

“So let’s say you’d have to supply something like 50 million barrels a day in 2050 of fuels,” he said. “That’s still a monster market.”

Carbon Engineering’s chief executive, added that direct-air-capture synthetics have an advantage over traditional fossil fuels: They won’t have to spend a dime on exploration

our plants, you can build it right in the middle of California, wherever you have air and water.” He told me that the company’s first large-scale facility should be up and running by 2022, and will turn out at least 500 barrels a day of fuel feedstock — the raw material sent to refineries.

Climeworks recently joined a consortium of European countries to produce synthetic methane that will be used by a local trucking fleet. With different tweaks and refinements, the process could be adapted for diesel, gasoline, jet fuel — or it could be piped directly to local neighborhoods as fuel for home furnaces.

the new fuels are not necessarily cheaper. Carbon Engineering aspires to deliver its product at an ultimate retail price of about $1 per liter, or $3.75 per gallon. What would make the product competitive are regulations in California that now require fuel sellers to produce fuels of lower “carbon intensity.” To date this has meant blending gas and diesel with biofuels like ethanol, but it could soon mean carbon-capture synthetics too.

Since they’re made from airborne CO₂ and hydrogen and could be manufactured just about anywhere, they could rearrange the geopolitical order — tempering the power of a handful of countries that now control natural-gas and oil markets.

From an environmental standpoint, air-capture fuels are not a utopian solution. Such fuels are carbon neutral, not carbon negative. They can’t take CO₂ from our industrial past and put it back into the earth

Even so, these fuels could present an enormous improvement. Transportation — currently the most significant source of emissions by sector in the United States — could cease to be a net emitter of CO₂

“If you can do one carbon-capture facility, where Carbon Engineering or Climeworks can build a big plant, great. You need to do that 5,000 times. And to capture a million tons of CO₂ with direct air capture, you need a small power plant just to run that facility. So if you’re going to build one direct-air-capture facility every day for the next 30 years to get to some of these scenarios, then in addition, we have to build a new mini power plant every day as well.

It’s also the case that you have to address two extraordinary problems at the same time, Peters added. “To reach 1.5 degrees, we need to halve emissions every decade,” he said. That would mean persuading entire nations, like China and the United States, to switch from burning coal to using renewables at precisely the same time that we make immense investments in negative-emission technologies.

this would need to be done even as governments choose among competing priorities:

“The idea of bringing direct air capture up to 10 billion tons by the middle or later part of the century is such a herculean task it would require an industrial scale-up the likes of which the world has never seen,”

Pacala wasn’t pessimistic about making a start. He seemed to think it was necessary for the federal government to begin with significant research and investments in the technology — to see how far and fast it could move forward, so that it’s ready as soon as possible

Gebald and Wurzbacher seemed to regard the climate challenge in mathematical terms. How many gigatons needed to be removed? How much would it cost per ton? How many Climeworks machines were required? Even if the figures were enormous, even if they appeared impossible, to see the future their way was to redefine the problem, to move away from the narrative of loss, to forget the multiplying stories of dying reefs and threatened coastlines — and to begin to imagine other possibilities.

The 24 at the Transportation Department lag behind only the 31 at HHS and 47 in the executive office of the president.

The swamp has overflowed, with lobbyists employed by Trump quintupling over two years. Boeing, American Airlines and 31 other corporate entities landed at least five former lobbyists apiece. Public Citizen reported that, five months into the administration, nearly 70 percent of top nominees had corporate ties.

In addition, the billions of dollars that corporate executives invest in lobbying and campaign contributions have generated healthy returns: a corporate tax cut, an assault on regulations and unrelenting efforts to shrink enforcement. The president, who previously attempted to privatize 30,000 FAA jobs, again proposed slashing the FAA in his budget this week.

Corporate victories keep coming. The Los Angeles Times just obtained emails showing that EPA officials moved to block NASA from monitoring pollution levels. Politico recently obtained data that showed that the Interior Department gave oil drillers nearly 1,700 waivers of safety rules implemented after BP’s Deepwater Horizon disaster in the Gulf of Mexico in 2010.

The Union of Concerned Scientists has documented more than 70 “attacks on science,” many benefiting corporations: censoring scientific language, suppressing studies, weakening advisory panels and such. The group suspects “inappropriate corporate influence” in rolling back fuel efficiency, chemical and methane standards, repealing the Clean Power Plan, suppressing known health risks, expanding oil and gas leasing and bailing out the coal industry, among others.

That food waste in landfills generates carbon dioxide and methane, a greenhouse gas 28 to 36 times more effective at trapping heat in the atmosphere than carbon dioxide

you are not just wasting calories and money. You are wasting all the resources that went into growing, packaging and transporting that food.

The FDA, researchers and the grocery manufacturing industry largely agree on an initial solution to this particular part of the food waste problem: clearer package-date labels.

In 2017, the grocery industry, led by the Grocery Manufacturers Association and the Food Marketing Institute, announced a voluntary standard on food-date labeling. They narrowed the plethora of date-label terms down to two: “best if used by” and “use by.” “Best if used by” describes product quality, meaning the product might not taste as good past the date but is safe to eat. “Use by” is for products that are highly perishable and should be used or tossed by that date

while the FDA is encouraging manufacturers to use “best if used by” as a best practice, it is still not required by law. There is no federal law that requires dates on food, except for infant formula.

to have an effect, these changes need to be federally mandated.

“They’re trying to bring clarity to the descriptor of the date. Okay that’s great, that’s better than what we have now,” he said. “But I think some things just shouldn’t be dated."

Indigenous peoples are more threatened than ever. Residents joust constantly with nature in unpredictable ways, leaving them feeling baffled, unsettled, helpless, depressed and irritated

“Everything is changing, people are trying to figure out how to adapt,” said Afanasiy V. Kudrin, 63, a farmer in Nalimsk, a village of 525 people above the Arctic Circle. “We need the cold to come back, but it just gets warmer and warmer and warmer.”

Climate change is a global phenomenon, but the shifts are especially pronounced in Russia, where permafrost covers some two-thirds of the country at depths ranging up to almost a mile.

“People don’t comprehend the scale of this change, and our government is not even thinking about it,

In a regionwide pattern, the average annual temperature in Yakutsk has risen more than four degrees, to 18.5 F from 14 F, over several decades, said Mr. Fedorov of the permafrost institute.

Warmer winters and longer summers are steadily thawing the frozen earth that covers 90 percent of Yakutia. The top layer that thaws in summer and freezes in winter can extend down as far as 10 feet where three feet used to be the maximum.

Nalimsk hunters once stored their fish and game in a 22-foot deep cave dug out of the permafrost, a kind of natural freezer. Now its thawing walls drip water, and the meat rots.

Even state-run institutions like the permafrost institute lack the means for the complicated field work needed to assess the full extent of permafrost loss. Nor can they gauge other fallout, like how much methane that microbes in the newly thawed ground produce, adding to global warming.

The loss of permafrost also afflicts the capital, Yakutsk. Subsiding ground has damaged about 1,000 buildings, said the mayor, Sardana Avksentieva, while roads and sidewalks require constant repair.

it is entirely possible to grow food that’s better for us and grow it in ways that are better for the land. Better land management techniques include limiting the use of fertilizers that contribute to emissions and planting crops that add carbon to the soil.

The way forward, they point out, requires reducing planet-warming emissions, removing carbon from the atmosphere by storing it in trees or soil, and changing diets, especially among the world’s wealthy.

it also requires a hard look at who gets to eat what

when it comes to land use, better forest management has the “largest potential for reducing emissions.”

“Farming must work with nature, not against it,

“The I.P.C.C.’s land report puts a big question mark on the future of industrial agriculture.”

Scientists often refer to these as “natural climate solutions,” and they point out that sequestering carbon in the soil not only helps slow down climate change, it can also make the soil hardier to deal with extreme weather events and ultimately increase crop yields.

The world’s forests are under intense threat, though, especially in the tropics. They are cleared for things we consume, including soy, palm oil and beef cattle

Nowhere is that more stark than in the world’s largest rain forest, the Amazon. Its destruction has increased drastically since Brazil’s far-right president, Jair Bolsonaro, took power with a promise to further open the forest to commercial exploitation.

Livestock can be raised on lands that are too arid to grow crops, they can be fed differently so they produce lower methane emissions and they produce manure that can fertilize soil.

animal protein is vital nourishment for a hungry child and raising animals has been part of the culture and livelihood for millions of people around the world.

But if the heaviest meat eaters in places like the United States and Australia cut back on meat, especially red meat, it would make a big difference.

It is entirely possible to eat well without depriving ourselves. There are tips we can borrow from many traditional cuisines.

Taken together, the amount of food that is wasted and unused accounts for close to a 10th of global emissions.

Curbing food waste is arguably the single most effective thing that can be done at an individual or household level to slow down climate change.
