CO2 Emissions by Man
I wonder if the CO2 scientists have accounted for the sequestering of carbon that results from increased crop yields. The natural limit on vegetation is apparently fertilizer, not carbon dioxide. Thus, with more fertilizer we have increased the amount of vegetation. We are eating more, too, but at any one time there is more carbon locked up in crops than there would have been 100 years ago. Trees have their own pattern, of course, and are better at sequestering carbon since they “waste” it in nonliving parts of the trunk.
Also, what would be the effect of the warming of Siberia and Canada on plant life? There would be a longer growing season perhaps– it might depend on sunshine instead of heat— but there might be fewer trees and more bushes.
