Bill McKibben to Obama: Say No to Big Oil | Moyers & Company | BillMoyers.com - 0 views

  •  
    In the second half of this interview, McKibben addresses the need to make urgent modifications to our systems of energy production. Video and written transcript are accessible: "We've been given the warning by our scientists who have done a terrific job at reaching consensus on a different problem in physics and chemistry. They've told us that we're in deep trouble. They've told us what we need to do, get off fossil fuel. The question now is whether we're actually going to respond to that. And it's like a sort of, well, it's like a kind of final exam for the question, was the big brain a good adaptation or not, you know? We're going find out in short order."

Good news on ozone, bad news on greenhouse gases | Ars Technica - 0 views

    " Good news on ozone, bad news on greenhouse gases The ozone layer is on track for recovery even as carbon emissions boom. by John Timmer - Sept 13 2014, 2:10am CST ShareTweet 42 The Montreal Protocol, created in response to the decline in the Earth's ozone layer, called for a world-wide phase out in the production of chemicals that were responsible for the ozone's decline. It is perhaps the greatest global environmental achievement to date. And, this week, the World Meteorological Organization and the United Nations Environmental Program announced it was working. Unfortunately, this week also saw the WMO release its annual greenhouse gas bulletin, and here the news was nowhere near as promising, as emissions returned to levels not seen since the 1980s. First, the good news. In the 2014 version of the Scientific Assessment of Ozone Depletion, the WMO finds that the atmospheric concentrations of most of the chemicals covered by the Montreal Protocol are in decline. The exceptions are hydrochlorofluorocarbons, which are used in refrigeration, and halon, used in fire suppression. The WMO also noted that there must be some unidentified source of carbon tetrachloride to explain its persistence in the atmosphere."

Exxon's Never-Ending Big Dig - BillMoyers.com - 0 views

  • The deepest problem is Exxon’s business plan. The company spends huge amounts of money searching for new hydrocarbons. Given the recent plunge in oil prices, its capital spending and exploration budget was indeed cut by 12 percent in 2015 to $34 billion, and another 25 percent in 2016 to $23.2 billion. In 2015, that meant Exxon was spending $63 million a day “as it continues to bring new projects on line.” They are still spending a cool $1.57 billion a year looking for new sources of hydrocarbons — $4 million a day, every day.
  • That’s why it’s wildly irresponsible for a company to be leading the world in oil exploration when, as scientists have carefully explained, we already have access to four or five times as much carbon in the Earth as we can safely burn.

IPCC finally weighs in on how to avoid further climate change | Ars Technica - 0 views

  • growth is accelerating.
  • from 1970-2000 was about 0.4 billion tons more each year
  • three-quarters of these emissions come from fossil fuels
  • ...9 more annotations...
  • rest come from things like deforestation, livestock production, and industrial pollutants.
  • much is due to economic growth and the rising use of coal in places like China.
  • population growth
  • Combining all anthropogenic climate forcings—including greenhouse gases, land use changes, and sunlight-reflecting aerosol particles—gives a net result equal to a CO2 concentration of around 430 parts-per-million
  • it must come back down to 450 parts-per-million by the end of the century
  • it’s clear that low-carbon options like renewables, nuclear energy, and fossil fuels with carbon capture will need to account for more than three-quarters of all electrical generation by 2050 if we’re going to meet that two degree Celsius target
  • Despite strong urban growth in many places, energy use in buildings could level off or decrease by the middle of this century if the right choices are made in terms of efficiency
  • long-lasting infrastructure we put in place now can determine, to a large degree, how much energy residents of a city will need to use
  • And while we’ve made some progress on deforestation, there’s potential there as well—forests and agricultural lands could be pulling CO2 out of the atmosphere, rather than releasing more, by the end of the century

Germany, the Green Superpower - NYTimes.com - 1 views

  • what the Germans have done in converting almost 30 percent of their electric grid to solar and wind energy from near zero in about 15 years has been a great contribution to the stability of our planet and its climate.
  • “In my view the greatest success of the German energy transition was giving a boost to the Chinese solar panel industry,” said Ralf Fücks, the president of the Heinrich-Böll-Stiftung, the German Green Party’s political foundation. “We created the mass market, and that led to the increased productivity and dramatic decrease in cost.”
  • A German foreign policy official put their dilemma this way: “We have to get used to assuming more leadership and be aware of how reluctant others are to have Germany lead — so we have to do it through the E.U.”Here’s my prediction: Germany will be Europe’s first green, solar-powered superpower. Can those attributes coexist in one country, you ask? They’re going to have to.
