GW THEORY DOES NOT FIT SATELLITE DATA

This report in the Australian contains an interview with Jennifer Marohasy, a biologist and senior fellow of Melbourne-based think tank the Institute of Public Affairs, who has studied the latest research into climate. In part of the interview she referred to NASA's Aqua satellite programme, launched in 2002. It enabled the collection of data, not just on temperature but also on cloud formation and water vapour.

What the data from the satellite shows is that a little bit of warming causes weather processes to compensate, so they're actually limiting the greenhouse effect and causing a negative rather than a positive feedback. This is the opposite of what the computer climate models suggest, which is that warming from additional carbon dioxide will result in increased water vapour, which gives a positive feedback. The meteorological community are having trouble digesting the findings. They accept that the satellite data does not fit the models and will have to come to terms with the fact that the computer models need to be overhauled. The new models are expected to show greatly reduced future warming.
