The length of time the earth has existed has nothing to do with what's happening now. For most of the earth's existence humans did not exist. This is really happening whether or not you believe it, also here is something I can never figure out.
Fine you don't believe climate change is real. But don't you have to consider what if it is?

And it's really too late? What then?
