Glover and Hansen and McKibben and Suzuki, oh my: Warmists claim that "Keystone Pipeline would also be a fifteen hundred mile fuse to the biggest carbon bomb on the continent, a way to make it easier and faster to trigger the final overheating of our planet"

Environmental Leaders Call For Civil Disobedience to Stop the Keystone XL Tar Sands Pipeline : TreeHugger

As you know, the planet is steadily warming: 2010 was the warmest year on record, and we've seen the resulting chaos in almost every corner of the earth.
...Keystone Pipeline would also be a fifteen hundred mile fuse to the biggest carbon bomb on the continent, a way to make it easier and faster to trigger the final overheating of our planet, the one place to which we are all indigenous.
... We very much still want to believe in the promise of that young Senator who told us that with his election the 'rise of the oceans would begin to slow and the planet start to heal.'
