Diane Sawyer conducted a surprisingly tough interview with Al Gore

Good Morning America’s Diane Sawyer conducted a surprisingly tough interview with Al Gore on Tuesday, pressing him on profiting from global warming and whether or not climate change legislation is pointless in light of pollution-spewing countries such as China. She also forced the ex-Vice President to respond to a challenge from Glenn Beck.
Sawyer even pointed out the amount of methane gas created from the bodily functions of cows, observing that it's "20 times more damaging it is than CO2." The host, who will become the anchor of World News in January, then played a clip of Fox News' Beck mocking Gore:
GLENN BECK: I'm siding with PETA on this one. Once again asking Al Gore if you really want to save the planet, Al, why don't you put down the cheeseburger and pick up the veggie burger? Time for, maybe, soy milk and tofurkey.
