Unpublished letter to the Sydney Morning Herald
Did you know a major glaciation occurred at extremely high CO2 levels at the end of the Ordovician? How could this be if CO2 is the main agent of climate change? Did someone forget to tell the IPCC! Geologists know the climate changes but sadly it seems politicians and the press are more willing to trust the results of incomplete computer models. Climate models are useful but while they are in an early stage of development its best to take a skeptical view of their output.
