Your Carbon Footprint Was Just a Baby Step.
I recently watched an episode of Miracle Planet, where they explained a disturbing geological fact. Increasing carbon in the atmosphere is only the prelude to a far more unstoppable threat: Methane Hydrates - vast deposits of methane gas frozen in the polar regions, and at the bottom of the oceans, and a global temperature increase of only a few degrees will set a catastrophic chain-reaction in motion. Methane is 20 times more effective as a greenhouse gas than carbon, and these frozen reserves exist in quantities many times larger than all other fossil fuels combined.
Fossil evidence shows that increased carbon raises the temp just enough for some methane to be released, and then the greenhouse effect ramps up steeply, as more and more methane melts. Seas may rise hundreds of feet, atmospheric oxygen drops to lethal levels, and the system may not recover for 100,000 years.
Surely this can't happen? Sorry, it already has - at least twice. The most recent one killed 1/2 of all life, and the one before that nearly wiped it off the globe.
