From:
Clips of Ken Ward's address on climate at Tufts University 3/28/9:
"...We need to completely remake society in very short order or we're fucked...go to youtube and google 'farting ice'...knocking a hole in the ice, handing...a fiery brand and saying to the journalist 'Go ahead, stick it in there', and so he does, and it blows up...sends a 16 foot sheet of flame into the air...We're not really wanting to have methane bubble up like that in Siberian lakes...far worse than the worst expectation..."
