Well, one way that man could change the exchange of heat would be to set off every nuclear bomb that exists in the whole world, creating a nuclear winter. Off topic yes, but it shows that what you said is certainly not impossible.

Read the thread. I already refuted that. It would not be a long-term effect. Man annihilates himself with a nuclear winter, then everything comes back to normal again within decades. Man can't impact the long-term thermodynamics of the Earth and the solar system. Sorry dumb ass!
I'm not sure that it would take only decades for the atmosphere to return to normal, it could take much longer. I guess it has to do with your definition of "long term". Also no need for ad hominem attacks, calling me a dumb ass is not constructive to the debate. Also nothing you've said proves that man is not capable of impacting the long term temperature of the Earth.

well no, it's a well known fact that the composition of the atmosphere does have an effect on the thermodynamics of planets. Different gases in the atmosphere will cause the planet to retain more or less heat. We can see this by studying other planets.

You've got that backasswards. The long-term composition of the atmosphere is dictated by the thermodynamics of the earth, not vice versa. The longer explanation of why that is so is your homework assignment. I will give you one tidbit to start with, which is that CO2 lags temperature rises (and declines) by 200 - 800 years because it is the warming and cooling of the oceans that cause the release of more or less CO2 from the massive mass of the oceans. Humans can't impact enough mass to offset the effect on the oceans. The Earth is a self-stabilizing system because of this huge heatsink, and the main heat sources are internal below the crust and the Sun (by many orders-of-magnitude than anything humans can do on a long-term basis).

This may have been true in the past, but a lot of research suggests that CO2 both is an effect of warming, and causes it through feedback loops.

Not to mention there are many other factors involved, such as the release of methane from permafrost which could create more serious feedback loops in regards to the greenhouse effect.
