We've had this argument before, and it's a specious one. Switching to
biofuels does not significantly reduce the amount of carbon being loaded
into the atmosphere, nor does it trigger the earth to assimilate carbon
faster. The dramatic rise in atmospheric CO2 since 1800 has been a result
of burning carbon-based fuels faster than the earth can assimilate it. It
makes no difference which carbon-based fuel is being burned, rapid
atmospheric CO2 loading will still occur. The only way to reverse the trend
is to reduce the burning of carbon-based fuels to a point where the
assimilation rate exceeds our emission rate. The bigger the difference, the
faster the CO2 levels in our atmosphere will decline.



It's only specious in your eyes, and it's surely no argument. It's a
fact. Burning fossil fuels releases new CO2 into the air, adding to
concentrations, burning biofuels releases co2 removed in the previous
growing season, not adding to concentrations. That's all there is to it.
