Global warming "tipping point": Siberia is melting  
Siberia is thawing. Earth is about to get up to 70 Billion Tons of methane into its atmosphere, a far more potent greenhouse gas than CO2. Hope all those SUV's were worth it.

Same's happening in Canada. I don't have references for it off-hand, though....

Lots and lots of methane hydrate is stored on the seafloor. There's a theory that if the oceans warm up enough it'll all melt. Of course as the ocean warms it becomes more acidic, which leads to differential solubility of carbonates and such. And that leads to coral reef instability. Which leads to ecosystem collapse in some regions. I guess we'll have to wait and see if it all happens.

Ironically, methane hydrates have only recently been used as a prospective new source of energy.

PS - Did you see that the marine ecosystem has collapsed in the US/Canadian Pacific NW?
