Per Espen Stoknes: Why and how can psychology be applied to the issue of climate change? Recorded at the Psychology of Climate seminar, 28 September 2012. Possible new climate policies are introduced.

The National Research Council is pleased to present this video that explains how scientists have arrived at the current state of knowledge about recent climate change and its causes.

There was much media attention a couple of weeks ago when this year's sea ice extent minimum broke all records: it was down almost 50 percent from the 1979-2000 average. Little attention, though, accompanied a possibly even more significant figure, released a few days ago: those who run the PIOMAS sea ice volume model at the Polar Research Center showed the 2012 sea ice volume minimum was down almost 50 percent not from decades ago -- but from 2007! That's right: the volume of arctic sea ice this September minimum was probably about half of what it was, just back in 2007.

Jason Mark via Earth Island Journal – “Methane is 21 times more heat-trapping that carbon dioxide.” If you’re a frequent reader of environmental websites, no doubt you’ve seen some version of that sentence many times. The “twenty-times” figure is the most common way of explaining how methane (or CH4, or uncombusted natural gas) reacts in the atmosphere.

2012 is likely to set a new sea ice minimum record. This is based on expected values on exponential trends. Here is a compilation of current observation and images.

The film charts the growth of humanity into a global force on an equivalent scale to major geological processes.

The film was commissioned by the Planet Under Pressure conference, London 26-29 March, a major international conference focusing on solutions.

Mike MacCracken was the first high level climate scientist that Al Gore introduced me to in Nashville, some 5 years ago. Although I knew something about the issue, and had some background reading and writing about energy and environment – Mike very quickly made me realize how much I had wrong, and how much I had to learn. He has been a reliable and generous advisor and mentor ever since. I owe him a lot for his patience in answering questions and pointing me to people and resources I needed to be aware of.
