SV: Humans causing Global warming > evidence increases

Aren't we being a little dramatic here. I always point out to every
environmentalist bent on telling me that the world is being destroyed
that every drop of oil and every lump of coal at one time in the past
was part of the biosphere, and the fact we are having this
conversation is proof that we can't add enough carbon to the
atmosphere to destroy the eco-system of this planet.
