We have spoken about this endlessly in college

The world goes through this anyway the temperatures rise and plummet over a period of time.. so whether we contributed or not the earth would be doing this anyway. the difference is that we are making the process speed up slightly so really all we can do is slow the process down not stop it or put it into reverse...
remember its not the earth we need so save its ourselves and the wildlife we live with!
