Here are some good reasons to question the AGW hypothesis from Australia. This is from the blog by Dr. Jennifer Marohasy and is written by Michael Hammer.(He is an engineer, not a Private Investigator like the American Mike Hammer.) To me, one of the interesting things about the AGW hypothesis is that all climatic events are said to prove the hypothesis. Such as, current droughts and floods in Africa are caused by AGW, as was the extremely cold weather experienced in Europe last winter, and the cold summer in the US this year. (Dr. James Hansen predicted that 2009 would be the hottest year on record. I expect his data will show that it was, even though everyone else thinks it was rather mild.)
