"angus... you didn't answer the question. what would happen in ten years to the global temperature if we were all dead. what would happen to it if we reduced our portion of co2 by 30%... How bout some hard numbers?"
Dead like by a neutron bomb?
Let's see. In just 10 years not much. CO2 would fall slightly. The warming would seize to increase perhaps, but would yet be continuing. Polar area meltings continue. Vegetation would change drastically in agricultural areas, depending on what happens to the lifestock though. That is a huge question. So, assuming a big drop in lifestock, areas will go from field to scrub. In just 10 years the difference would be notable.
Now pollution would drop, that affects the dimming effect, which is a plus for warming. So it's a matter of balance before co2 and others start dropping.
So in short, in 10 years, not much. Will probably be even warmer.
BTW, I have read an article about something very similar. Stepping from 100 years to 100.000 years.
Now I have a question for you.
What do you think will happen to the big oil companies, if alternative fuels start advancing, say 5% of the cake every year? In, say, 10 years?
