Al Gore tells Princeton students climate change is the new civil rights movement

Al Gore tells Princeton students climate change is the new civil rights movement:
"Former Vice President Al Gore compared the fight against climate change to the civil rights movement, and called on Princeton graduates to help to do their part at the university’s annual Class Day.
....Though Gore declared that decisions must be made “on the basis of reason and the best available evidence,” he warned against those who are skeptical on scientific evidence of global warming.
“They are merchants of doubt who present falsehoods in an effort to confuse people to the point where they can’t recognize the truth,” said Gore.
“They are doing exactly what the tobacco companies did 40 years ago, they hired actors and dressed them up as doctors.”
