Is one to infer from your post that perhaps the earth is better off without us humans? Maybe I'm reading too much into it. Of course climate changes, I guess your response is #2 of my list (which I'll recap in a numbered list to safe time for argument:

1: Climate change is a hoax and it's not happening - the science is flawed
2: Our climate is changing but it is natural process and it will fix itself
3: We might be contributing to it but there is nothing we can conceivably do to stop it
4: We could stop it but the economic consequences are too hard to deal with.

All of these arguments share the perspective that the motive behind the scientists detailing how the rapidly changing earth is their own economic self-interest, and not in any way based upon objectively measurable facts. Far better we stick our heads in the sand and do nothing.
