This is just the last 2 billion years. Not the 4.5 billion that the earth has been around. Do you see a trend? It warms, it cool, it warms, it cools. Were dinosaurs driving SUV's that created the global hot house that they lived in?
Anybody that thinks that the Earth actually gives a fuck that we are here is a total dipshit moron. The Earth could shake us off like a bad case of fleas anytime she decides to.
