I assume - just like everyone else - that if you double CO2 in, you have twice as much CO2 to get out. Now, bright boy, is that from CO2 being added to the atmosphere, or is the cancer called urban sprawl and rain forest harvests destroying vegetation which scrubs CO2 from the atmosphere?
Woof!
Yes, that is part of it bright boy, triple the population and remove half of the rainforest while pumping out out Carbon emmisions, that will also increase the amount of CO2 in the atmosphere.....what's your point?
The question was what happens when you double the amount of CO2, nothing?
Surely and smart dog like you can answer that one.
