Beem-Ur the Destructor

HCD? Part II

Okay! So as promised, the discussion of how to address the question of global warming / human climate disruption, given that it is steeped in uncertainty.

EDIT: I forgot about a couple other lines of evidence that strongly support the idea that increased CO2 is due to burning fossil fuels: (1) there's a geographic correlation (northern hemisphere vs southern hemisphere, taking into account atmospheric mixing times) between CO2 levels and industrialization, and (2) the isotope ratio of atmospheric carbon is consistent with the extra CO2 coming from fossil fuels. So actually, when you take that along with the correlation in timing and amount of CO2 increase, what I said above is wrong -- we ARE fairly sure where the extra CO2 is coming from, and it's from human activity.
