Climate scientist David Archer of the University of Chicago discusses his research on the Ultimate Cost of Carbon (UCC): The climate impacts of release CO2 if the negative effects are not discounted. He also discusses the *very* long term impacts that our emissions of CO2 have on the climate (~500,000 years!).
