Nov 10, 2011 Carbon Cycle 2.0 talk Donald DePaolo
Associate Lab Director for Energy and Environmental Sciences, LBNL
The root cause of climate change is what could be called "carbon cycle change." To change global climate, the amount of CO2 in the atmosphere needs to change, which in turn requires a change in the way carbon is moved around among the various forms and places it exists in and on the Earth. Today, 98 to 99% of the net movement of carbon out of geologic reservoirs into the atmosphere is due to human activities. Whether you think this is a problem or not, it is nevertheless a fact that we are currently doing something that is unprecedented in Earth history.
