My initial interest in global warming was driven by a desire to better understand water issues, and in particular the likely affect of increasing levels of carbon dioxide on Australian rainfall. After attending the ‘2008 International Conference on Climate Change’ in New York I was interviewed by Michael Duffy from Australia’s ABC Radio National and discussed the last 10 years of temperature data and also output from NASA Aqua Satellite (Climate Change, Michael Duffy, March 17, 2008). This interview was the focus of an opinion piece by Christopher Pearson in The Australian (Climate facts to warm to, Christopher Pearson, March 22, 2008), which was subsequently picked up by Fox News (Cooling Effect, Brit Hume, March 24, 2008).
It is interesting how quickly the theory of anthropogenic global warming (AGW) has come to dominate climate science, despite its evident lack of practical utility, and in particular the absence of any measurable improvement in the skill of rainfall and snowfall forecasts. This, despite an extraordinary investment in General Circulation Models (GCMs), which are a form of simulation modeling. I’m continually reminded of the Thomas Kuhn quote: “As in manufacture so in science, retooling is an extravagance to be reserved for the occasion that demands it.” Perhaps this time has arrived, thus my interest in ANNs.
