Start Date: 11/01/2010
Time: 4:30 pm
Location: 1 LeConte
Speaker: William Happer
Affiliation: Princeton
Details:

In this talk I will explain that atmospheric carbon dioxide (CO2) is not a pollutant but a beneficial and essential part of our atmosphere. Without CO2, higher forms of life would perish. Over most of geological history since the Cambrian, CO2 levels have been several times higher than now. Life flourished on land and in the oceans at these higher levels.
