      Making sense of Antarctic sea ice changes

      Antarctic sea ice is one of those things in the climate system that seems to confuse people. Antarctic sea ice, on average, is increasing. How can there be global warming if sea ice is increasing in the Antarctic? Some have gone so far as to average the Arctic sea ice loss with the Antarctica sea ice gains, and imply that globally sea ice isn't changing. That's just silly. Even so, it's fair to say that most of the popular explanations... Continue Reading...

Less than three months ago this was apparently an empty piece of land in a large Peruvian government complex, but now it is a bustling and well fitted out set of temporary buildings for housing negotiators and observers from some 190 countries; plus of course their entourage, a large security contingent, caterers, support staff and voluntary guides. The facilities are... Continue Reading...

      Climate Change and Timescales (Part 1): Why "Global Wobbling" doesn't matter

      At a recent meeting of the U.S. House of Representatives Committee on Science, Space and Technology, Rep. Steve Stockman (R-TX) asked White House Science Advisor John Holdren why "global wobbling" was not included in climate models of modern climate change (YouTube). After all, if global wobbling was so important in ending the last ice age, why does it not matter now. The answer has to do with timescale. Dr. Holdren did an admirable job answering this question during the hearing, but we'll... Continue Reading...
