Climate Change and the Earth System
The latest post on theclimateblog counters "climate skeptic" arguments that the present warming of Earth's climate is minor compared to those in the geologic past. Earth was warmer during the age of the dinosaurs, and there was most certainly more carbon dioxide in the atmosphere. However, the entire Earth System was so different that we are really talking about a totally different atmosphere with different patterns of circulation. Now I am waiting to see what the lady up in Chicago has to say about the Paleocene-Eocene Thermal Maximum!
