text: At this point I am reminded that James Hansen raised the alarm about global warming in 1988 when he had less than a decade of noisy global warming data on which to base his concern. The amount of warming heobserved between 1980 and 1988 was far smaller than known natural variations and far larger than the IPCC would go on to say was due to AGW during that period. So whatever the eventual outcome of the AGW debate, logically Hansen had no scientific case.
