Gore replies to Palin on climate change: "It's like gravity. It exists."

In an interview that will air on MSNBC at 1:00 pm ET today, Al Gore rebutted Sarah Palin’s Washington Post op-ed and Facebook postings that question the science on climate change given the “Climate-gate” controversy.

In response, Gore said that “the deniers are persisting in an era of unreality. The entire North Polar icecap is disappearing before our eyes… What do they think is happening?”…

Asked about Palin’s charge on Facebook that these are “doomsday scare tactics pushed by an environmental priesthood,” Gore replied that the scientific community has worked on this issue for 20 years. “It’s a principle in physics. It’s like gravity. It exists.”
