Re: US lawmaker, environmentalist spar over nuclear power
When evaluating the impact on CO2 production rates, timing makes all the
difference. The production of biomass fuels is contemporaneous with
utilization to within a couple of growing seasons (?).
This has two impacts: 1) CO2 removal millions of years ago produces no
benefit now as compared to biomass which produces a present benefit, and 2)
the rate of CO2 generation from combustion of fossil fuels is many times
greater than the rate of absorption of CO2 during its production as compared
to biomass which, when considering the time scale for affecting atmospheric
CO2 concentrations, absorbs CO2 at effectively the same rate as it releases
when burned.

That's of course equally true for fossil fuels, which are "biomass" fossils.
All of the carbon was at some time CO2 incorporated as biomass by
photosynthesis.
