Copenhagen climate summit concerns not justified by scientific forecasting

In their paper (http://kestencgreen.com/gas-2009-validity.pdf)) in the latest issue of the International Journal of Forecasting, Kesten Green, Scott Armstrong, and Willie Soon cast doubt on the need for concern over dangerous manmade global warming that is prima face motivation for the Copenhagen summit taking place this week. The authors' simple evidence-based model produced forecasts that were over seven times more accurate than forecasts from the procedures used by the United Nations Intergovernmental Panel on Climate Change (IPCC); the official provider of advice on climate change. A summary of the implications for the Copenhagen summit is available here (http://kestencgreen.com/climatemodelsleftcold.pdf).
