yeh scientists are very smart yet they still can't find a cure for cancer in 100 yrs plus... but now they've worked out how to manipulate the earth's climate. OK
the planet has been heating up and cooling down for years before humans got here and scientists can't explain why...sure none of us are in a position to debate "atmospheric physics" with MIT scientists (whoever they are). But some people can tell BS when they smell it.
I know you honestly believe that, because it's just good common sense, right?

Circa 1902, " If man were meant to fly, he'd have wings"
Circa 1491 , " If you sail in 1 direction long enough, you'll fall off the edge of the earth."
Circa 1542 , " God made the sun and planets move around the earth."
Circa 2007? , " It stings when the tip goes, in, then I lay back and let the good times roll" * TBombz

FYI, just because you don't understand something, doesn't mean its' false.
