CNN on Tuesday highlighted the UN’s Intergovernmental Panel on Climate Change use of a unsubstantiated claim about the Himalayan glaciers melting by 2035 to put pressure on politicians across the globe. Meteorologist Rob Marciano thought the “snafu” on the part of the IPCC was “inexcusable,” while anchor Rick Sanchez put the panel and its head on his “List You Don’t Want to Be On.”

Marciano brought up the week-old story during a segment 49 minutes into the 8 am Eastern hour. He played a sound bite from climatologist Jim White, who was attending the annual Steamboat Springs Weather Summit in Colorado (Marciano was on-location in Steamboat Springs). The CNN meteorologist voiced his agreement with White, who blasted the IPCC’s exaggeration:

If President Obama or any Democrat had actually won the dubious honor of committing PolitiFact's "Lie of the Year," do you think CNN would have reported it?

Fat chance, right?

Before you answer, consider the glee exhibited by CNN's Josh Levs Sunday when he announced Sarah Palin had "won" for her Facebook comment concerning a "death panel" in healthcare reform legislation (video embedded below the fold with transcript, h/t Story Balloon):

Hinting at but not explicitly charging President Obama with eco-hypocrisy, CNN weatherman Rob Marciano chided the chief executive for flying out to Iowa and back just for one Earth Day speech. Marciano took to the camera shortly after 10 a.m. EDT for a weather report. His comments came on the heels of Heidi Collins describing Obama's agenda for marking Earth Day [audio available here]:

ROB MARCIANO, CNN meteorologist: Is that the 747 Air Force One I see on the tarmac getting ready to go fly to Iowa for Earth Day?

HEIDI COLLINS, CNN anchor:  Yup.

MARCIANO: I mean, it's a pretty big carbon footprint just to make a speech in front of a windmill.

On Friday night, CNN viewers were treated to the special "Keeping Them Honest: The Truth About Global Warming," which took time to examine nine "alleged inconsistencies or exaggerations" in Al Gore's "An Inconvenient Truth," as enumerated in a ruling by a British judge. Host Miles O'Brien also interviewed a member of the IPCC, the group which shared the Nobel Peace Prize with Gore, in the form of a scientist who has challenged Gore's views on global warming. O'Brien, who a week earlier had tagged dissenters with such labels as "dead-enders" and "a very small fringe," on this show suggested that people who are "skeptical" about global warming are "in the dark," and presented what he called "surprising" polling data showing a substantial number of Americans have doubts about global warming theory.

How dare CNN Meteorologist Rob Marciano say Al Gore was wrong in his movie "An Inconvenient Truth?" Apparently, his comments from yesterday that "There are definitely some inaccuracies" in the film generated a lot of controversy and e-mails for the network.

Today was Round Two. And Marciano excelled by showing both sides of a debate Gore says doesn't exist and by pointing out even more of what Gore got wrong. First the wrong: "He does talk about tornados, implying that there's an increase in tornados from global warming, that's not necessarily true," said Marciano.

Then Marciano interviewed two climate experts from opposite sides of the battle, including "science and operations officer of the National Hurricane Center, a big time researcher named Chris Landsea." Landsea explained the limits of the Gorean hype machine. Read on for details and full transcript.

CNN Meteorologist Rob Marciano clapped his hands and exclaimed, "Finally," in response to a report that a British judge might ban the movie "An Inconvenient Truth" from UK schools because, according to "American Morning," "it is politically biased and contains scientific inaccuracies."

"There are definitely some inaccuracies," Marciano added. "The biggest thing I have a problem with is this implication that Katrina was caused by global warming."
