I believe global warming is grossly exaggerated as a problem. It's a real problem, but it's nothing like as serious as people are led to believe.

This means that large human disturbance of any one of these reservoirs will have large effects on all three. We cannot hope either to understand or to manage the carbon in the atmosphere unless we understand and manage the trees and the soil too.
