|Our review of
the carbon cycle raises some questions. Are these IPCC figures and data
subtly downplaying the degree of human influence on the carbon cycle? Is our
use of fossil fuels overemphasized as the source of the problem?
|A paper from
(Vitousek et al ) from 1986 suggests that humans appropriate about 40% of
plant production. That suggests we control 24 billion tonnes of the carbon
removed from the atmosphere by plants. That’s a lot bigger than the 6.3
billion tonnes we add from fossil fuels.
|Is it possible
we have greater opportunities to control atmospheric greenhouse gas levels
than to just reduce fossil fuel consumption? Could we take lessons from the
carbon cycle and strategically use more energy to manage levels of greenhouse
gases in the atmosphere? I think so.
