Greenland Ice Sheet: “Starting to Slip”

Published on YouTube Jul 29, 2013: Research scientists provide insights on recent ‘unprecedented’ melting of Greenland’s interior ice sheet. Latest video for The Yale Forum on Climate Change & the Media, the first since returning from Greenland – includes interviews with Ice expert Alun Hubbard, who I met in Kangerlussuaq, as well as a snip from…

NASA: Projected U.S. Temperature Changes by 2100

NASA: The average temperature across the continental U.S. could be 8 degrees Fahrenheit warmer by the end of the 21st century under a climate scenario in which concentrations of the greenhouse gas carbon dioxide rise to 800 parts per million. Current concentrations stand at 400 parts per million, and are rising faster than at any…

Why Global Warming Should Keep You Awake at Night: Dr. Jennifer Francis Gives Chilling Testimony to Congress

Via Robertscribbler: In a July 18 testimony to Congress, Dr. Jennifer Francis, an atmospheric scientist from Rutgers and key innovator to understanding how climate change has brought about dangerous alterations to the Northern Hemisphere Jet Stream, provides five compelling reasons why we should all be quite concerned about human caused global warming.

Stable Antarctic Permafrost Melting Faster than Expected

University of Texas: July 24, 2013 AUSTIN, Texas — For the first time, scientists have documented an acceleration in the melt rate of permafrost, or ground ice, in a section of Antarctica where the ice had been considered stable. The melt rates are comparable with the Arctic, where accelerated melting of permafrost has become a…

Understanding the long-term carbon-cycle: weathering of rocks – a vitally important carbon-sink

By John Mason / SkepticalScience   above: the processes of the long-term carbon-cycle that this post explores. Graphic: jg. This post delves into the long-term carbon cycle that involves the interactions of the atmosphere with rocks and oceans over many millions of years. Because of its length, I’ve broken it up into bookmarked sections for…
