As nature/sun, etc continue to naturally warm us up, more Co2 will naturally be releases. This happens because as the sun does it's job, ice melts, more light can hit the ocean, life starts and more and more Co2 is produced. As this happens more and more, the under ocean ice sheets thin out, releasing even more Co2 and methane into the air.
Without humans, we would have a lot more cows. And methane, is far more dangerous than Co2. One methane burp from the ocean and a single bolt of lightening can spark a match you haven't ever seen before.

It is correct that nature cause variations, but I do not think you understand how CO2 in energy budget works. When you burn off oil or coal, we DO add CO2 to the cycle and the molecules WILL stay in that cycle for many years. Without humans, it will go up,
yes, but we contribute to even more warming. That is the problem; at some point of time, it is supposed to cool again, but it won't happen because we affected the balance.
I'm not sure what you mean by "without humans, we would have a lot more cows". Why do you think so?
