Anderson Cooper reused a segment from CNN’s 2007 special “Planet in Peril” on his program on Tuesday, where he traveled to Greenland with a climate scientist to visit a melting glacier. The same scientist, who believes in manmade global warming, also appeared live with Cooper, and dismissed the ClimateGate scandal. The CNN anchor did not have any skeptics of manmade climate change on his program.

Cooper preceded his replay of his glacier report (which came 19 minutes into the 10 pm Eastern hour) with news briefs about the latest developments on the climate change debate: “Late word tonight that Sarah Palin is now calling for President Obama to boycott the United Nations climate conference in Copenhagen.

Meantime, a U.N. weather agency made news today at the meeting when it said the current decade will likely be the warmest on record, and 2009 will probably be the fifth hottest year.”

Though none of this who appeared during the two-year-old segment- Cooper, Jeff Corwin of the Animal Planet cable network, or the climate scientist, Dr. Conrad Steffen of the University of Colorado- explicitly mentioned the manmade component of the ice melting, Dr. Steffen played up the most dire predictions of sea level rise:
