Geophysicists David Archer and Raymond Pierrehumbert provide a joint perspective on rising CO2 levels in the atmosphere and their expected impact on the earth's climate. It's more than just a question of magnitude--this talk will address just how long (in geological terms) increased emissions will impact the planet's temperature, rainfall, sea level, and ice coverage. What are the ethical implications and economic arguments? Speaking from decades of research, Archer and Pierrehumbert will offer their thoughts on these questions and critique the thinking of some mainstream economists on climate change.Recommended reading:Climate Change: A Catastrophe in Slow Motion; RealClimate.org; The Long Thaw: How Humans are Changing the Next 100,000 Years of Earth's Climate; The millennial atmospheric lifetime of anthropogenic CO2; and Warming Papers (soon to be released by Blackwell/Wiley Press)
