We are destroying nature’s ability to help us stave off catastrophic climate change. That’s the bombshell conclusion of an under-reported 2014 study, “The declining uptake rate of atmospheric CO2 by land and ocean sinks,” as coauthor Dr. Josep (Pep) Canadell recently explained to me.

As the Pacific Island nation of Vanuatu is devastated by Cyclone Pam, 350.org co-founder Bill McKibben links the storm to global warming and responds to the new decision by the the United Nations Framework Convention on Climate Change to back the fast-growing divestment campaign to persuade investors to sell off their fossil fuel assets. This comes as University of Oxford alumni, donors and students are watching a vote set for today on whether the school will divest its endowment from the top 200 companies involved in exploring or extracting fossil fuels.

Paul Beckwith

From Paul Beckwith who is a good person to follow on issues of climate science. This is a good visual overview on changes to our climate/weather systems - what Paul is calling abrupt climate change. Makes all of our work that much more urgent.

The fear is this could lead to “runaway global warming” said Beckwith. Newly released methane warms the planet, in turn releasing more methane. If this loop is triggered, Beckwith thinks it may not be possible to stop planetary warming, even with human effort to curb emissions.

“It’s the most powerful feedback in the Arctic,” he added.

Abstract.  Global surface temperature in 2014 was +0.68°C (~1.2°F) warmer than the 1951-1980 base period in the GISTEMP analysis, making 2014 the warmest year in the period of instrumental data, but the difference from the prior warmest year (2010), less than 0.02°C, is within uncertainty of measurement.  The eastern two-thirds of the contiguous United States was persistently cool in 2014, cooler than the 1951-1980 average in all seasons.  Record warmth at a time of only marginal El Niño conditions confirms that there is no “hiatus” of global warming, only a moderate slowdown since 2
