It's probably a bad thing. From what little I understand: the earth has a lot of carbon dioxide and methane sequestered in permafrost, deep water, and ice. As the average temperature increases, the rate at which these gases are released also increases. So we're in a fairly dangerous positive feedback loop, because it doesn't take much of a temperature change for a lot of the places we live to become uninhabitable.
