Dr. David Suzuki, Canada's best-known environmentalist, says he's a big fan of his counterpart from south of the border.
"I interviewed Al Gore in 1988 and I tell you he sent shivers up my back. He'd been to Antarctica and been with scientists doing ice cores. He knew about global warming in 1988."
"He's real," Suzuki said. "And this guy's got a long track record. Thank God he's not in politics. He's been unbelievably effective as a communicator about global warming."
