Copenhagen // Sustainability, Climate Change, and Universities It’s been busy and I have been slow on the blogs. At the top of the list of busy is the Conference of Parties in Copenhagen in December. This is the fifteenth such meeting. It’s a show, where there is an attempt to build policy. The official focus of this will be beyond Kyoto. To some of us, it never really felt we got to Kyoto, but … Also every advocacy group in the world, both for and aga...

Still not getting warmer:

Sun, 18 Oct 2009 21:32:00 GMT

Still not getting warmer: In the previous blog I talked about a figure that has been floating around in blogworld making the case that IPCC predictions are wrong because they predict that the last four years should be getting warmer in each successive year and that has not been observed. This blog is about an interesting paper that also addresses that issue. The paper is by Judith Lean and David Rind. You might recall that I relied a lot on their work in the ser...

Extreme Feedbacks

Arctic Extreme Feedbacks My previous blog was on a paper that argues from a variety of points of view that the Arctic is showing definitive warming, despite a substantive reduction in solar radiation due to the wobbling of the orbit of the Earth. This blog is also on the Arctic, and specifically a scientific assessment sponsored by the World Wildlife Federation (WWF). (Yes, I know that the WWF takes an advocacy position.) The report has excellent summaries of s...

Arctic is Extreme

Thu, 24 Sep 2009 02:10:00 GMT

Arctic is Extreme A couple of blogs back in August I talked about this summer’s sea ice in the Arctic and the implications of an ice-free Arctic Ocean on national security. Jeff Masters recently had a blog that updated both sea surface temperature and Arctic sea ice. The ocean is still warmer than ever observed, and sea ice was the third lowest observed. The last three years have been the three lowest of a relatively short sea ice observation record. In the l...
