A Longer History February 2, 2007

Posted by Jim Satterfield in Environment, Politics, Science.

Recognition of the potential threat for Anthropogenic Global Warming, or AGW for short and global warming in the much more common references has a much longer history than most people realize, Naomi Oreskes points out in the Washington Post today.

It was established in the Nineteenth Century that CO2 is a greenhouse gas. In the early 20th Century Arrhenius, one of the foremost chemists of the day deduced that it meant that people producing enough CO2 could alter the climate. It goes on from there with the history of some of the people who built on the earlier realizations. Keep this in mind the next time someone makes a big deal out of the Newsweek and Time articles from the 1970s that spoke of cooling. There wasn’t exactly a consensus for that one as there is now for mankind being largely responsible for warming.
