Climate models define the uncertainties ahead

Ronald Prinn, professor of atmospheric chemistry at MIT and a leading climate scientist, is one of the lead authors of the recent IPCC report. He directs a worldwide project that monitors the amounts of greenhouse gases in the earth's atmosphere. Professor Prinn recently sat down with MIT's Technology Review - he discusses climate science challenges and very simply explains the modeling processes that the IPCC used to arrive at the 90% probability that people are causing global warming: Measuring the Uncertainty of Climate Change
