Opposite Views on Climate Feedbacks (and perhaps the answer lies in the middle)

By Chip Knappenberger -- March 5, 2009 14 Comments

Just how much warming should we expect from rising levels of atmospheric greenhouse gases (GHGs)? The answer largely hinges on how much extra warming might be generated by the initial warming—that is, how strong (and in what direction) are the feedbacks from water vapor and clouds.

By most estimates (including climate model outcomes), these feedbacks are positive and result in about a doubling of the warming that would result from greenhouse gas increases alone. By others, however, the total feedbacks are negative,…

Ken Green on the New ‘Denialists’ (circling the wagons on Climategate)

By -- January 2, 2010 6 Comments

 [Editor Note: This piece originally appeared in the Calgary Herald on December 28th. It should be noted that a new website is devoted to Climategate.]

Responses to “Climategate”–the leaked e-mails from Britain’s University of East Anglia and its Climatic Research Unit — remind me of the line “Are your feet wet? Can you see the pyramids? That’s because you’re in denial.”

Climate catastrophists like Al Gore and the UN’s Rajendra Pachauri are downplaying Climategate: it’s only a few intemperate scientists; there’s no real evidence of wrongdoing; now let’s persecute the whistleblower. In Calgary, the latest fellow trying to use the Monty Python “nothing to see here, move along” routine is David Mayne Reid, who penned a column last week denying the importance of Climategate.

Unfortunately for Professor Reid, old saws won’t work in the Internet age: Climategate has blazed across the Internet, blogosphere, and social networking sites.…

Andrew Dessler and Gerald North on Climategate, Climate Alarmism, and the State of Texas’s Challenge to the U.S. EPA’s Endangerment Finding (Part I in a series)

On March 7th, the Houston Chronicle published an editorial by two Texas A&M climate scientists, Andrew Dessler and Gerald North (et al.):  “On Global Warming, the Science is Solid.” The op-ed argued that Climategate was a mere distraction and that climate science was settled in favor of alarm–both points being intended to challenge the State of Texas’s Petition for Rehearing to the U.S. Environmental Protection Agency’s endangerment finding, which was based on a belief of “settled science.”

A week later, a response/defense followed in the Chronicle, written by Texas Attorney General Greg Abbott: “State Suing for Responsible Scientific Conclusions.”

“Texas’ challenge to the EPA’s endangerment finding on carbon dioxide contains very little science….”

– Andrew Dessler, Gerald North, et al….., “On Global Warming, the Science Is Solid,” Houston Chronicle, March 7, 2010. [Also see yesterday’s Part I post on Dessler/North.]

Last month, the State of Texas filed a petition for reconsideration in the U.S. Court of Appeals for the D.C. Circuit (summary here) against the U.S. Environmental Protection Agency (EPA). The Petition lays out why the EPA’s reliance on the Intergovernmental Panel on Climate Change (IPCC) to provide an assessment of climate change science was a very bad idea.…
