Environmental activism works, study shows

The environmental movement is making a difference – nudging greenhouse gas emissions down in states with strong green voices, according to a Michigan State University (MSU) study. Social scientist Thomas Dietz and Kenneth Frank, MSU Foundation professor of sociometrics, have teamed up to find a way to tell if a state jumping on the environmental bandwagon can mitigate other human …

IEA warns of 4.3C temperature jump from climate change

The International Energy Agency on Monday warned temperatures could jump by as much as 4.3 degrees Celsius by the end of the century and urged countries to improve their pledges on reducing emissions. In a report ahead of a climate change conference in Paris this year, the IEA said more should be done to reach the goal of keeping the …

Long-lived carbon dioxide warms the world for many millennia By Tim Radford

Gun the engine, and the ignition of fossil fuel produces not just working energy but heat that dissipates quickly into the atmosphere. But it also produces carbon dioxide that dissipates into the atmosphere. And in less than two months, according to new research, that pulse of carbon dioxide will have engendered more heat for the planet than the original touch …

In Fight Against Global Warming, the World is Way Off Target – Deirdre Fulton

In what is being called the most definitive assessment yet of national emissions pledges aimed at meeting global climate goals, the International Energy Agency on Monday released a major report showing that without “learning to live within its means,” the world is set to miss a critical target. In its World Energy Outlook Special Report 2015: Energy and Climate Change (pdf), the Paris-based agency states that …

Pope Francis’s Encyclical Could Have Bigger Impact Than the Paris Climate Talks, Says NASA Scientist – Lorraine Chow

As the world eagerly awaits Pope Francis′s encyclical on climate change this Thursday, some scientists have come out and said that the papal letter could draw a larger impact than the world leaders hammering out emissions negotiations at the UN climate summit in Paris this December. “I’m not a religious person at all,” NASA climatologist Gavin Schmidt told USA TODAY, adding that faith-based efforts to shift thinking on climate …

Boreal peatlands not a global warming time bomb

To some scientists studying climate change, boreal peatlands are considered a potential ticking time bomb. With huge stores of carbon in peat, the fear is that rising global temperatures could cause the release of massive amounts of CO2 from the peatlands into the atmosphere–essentially creating a greenhouse gas feedback loop. A new study by researchers at the University of South …

Faking It While the World Burns By Emily Schwartz Greco

Rex Tillerson, of all people, just did the climate movement a big favor. He didn’t hand the Sierra Club tens of millions of dollars to fight the coal industry like former New York City mayor Mike Bloomberg. Nor did the chairman and CEO of Exxon Mobil follow former hedge fund investor Tom Steyer‘s lead by giving political candidates with climate cred campaign …

With 2°C Target Falling Swiftly Out of Sight, Inaction on Climate a ‘Crime Against Humanity’ – Jon Queally

International climate talks continue, but its is the action (or lack thereof) that humanity needs to worry about. “By ignoring the need to prevent a breach of the 2C tipping point, the point beyond which scientists are unable to predict the sheer scale of [climate] impacts… Paris will go down in infamy as the scene of a modern day crime against humanity.” — Asad Rehman, Friends of …

The Politics of the California Drought by ARUN GUPTA

As if in compensation for a historic drought, California is being deluged by expressions of grim satisfaction that it is finally getting its comeuppance for environmental sins. Judgement was especially swift after California Gov. Jerry Brown imposed a 25 percent reduction in water usage for urban areas. The media asked if this is “The End of California?”, as well as declaring “So …

Everest Region May Experience 99% Glacier Loss

With continued temperature rise, glacier volume in the Everest region could be reduced between 70% and 99% by 2100. If greenhouse-gas (GHG) emissions continue to rise, glaciers in the Everest region of the Himalayas could experience dramatic change in the decades to come. A team of researchers in Nepal, France and the Netherlands have found Everest glaciers could be very sensitive to future warming, and that sustained …
