Climate Change

It's a well known fact that humans cause climate change on earth. Therefore, because climate change exists it proves that humans inhabit the planet earth. This correlation between mankind and earth's climate change is true and we only have to consult Al Gore to prove it. Recente climate change also exists on a number of other bodies in the Solar System, such as Mars, Io, Europa, Titan, and Triton. This, therefore, also proves that Martians exist, as do Ioians, Europians, Titanians, and Tritonians. I don't know about Venusians. It's difficult to determine if climate change actually occurs on Venus with its dense atmosphere. Isn't it amazing that leading science minds, such as Al Gore's, have managed to prove that intelligent life exist on at least one other planet and a number of moons in the Solar System. Who would have been able to imagine such an occurrence from the simple study of Earth and its mankind caused climate change. I think that this should qualify someone for a Nobel prize. Any takers?
