One of the curious facts about the Anthropogenic Global Warming debate is that the NASA/GISS temperature record shows that the earth is warming while other records do not. Then, as I have mentioned before, there is the curious fact that NASA/GISS keeps revising the temperature record so that earlier periods keep getting colder while the recent past keeps getting warmer. One thing I have commented on before is that I read that pine beetles in the southeastern US are getting more active, yet the temperature record shows that the temperature in the southeastern US declined during the twentieth century. So, how did the beetles know to get more active. No doubt they have some special insect sense that told them Al Gore had declared a state of global warming. Here is a site that has interesting data showing the divergence of the NASA/GISS data and other temperature records (for those who don't know, James Hansen works at NASA/GISS and Al Gore worked with that agency on Global Warming while he was VP):

Is there chicanery, or just an honest disagreement? It is hard to say, but it is interesting that NASA/GISS, run by the nost ardent supporters of AGW, is the outlier data set.
