Global warming does not contradict the law of conservation of energy because energy is not being created in the system. Instead, energy is entering the system via the sunlight as it always has, but the difference now is that human emissions of carbon dioxide are changing the make-up of the atomosphere which the heat energy used to be able to escape from. While it may seem like humans are “creating” carbon dioxide, it is merely that we are converting mass, such as natural gases from the earth into energy and carbon dioxide. Because of these two pieces, the energy is clearly, in no part of the global warming process, being created within the system, but rather merely added by the sun as it always was.
