And there's no political agenda for the warming-is-real crowd?

Then why did these guys choose Media Matters as the venue in which to lodge their protest against the NIPCC?

On September 18, two scientists sent emails to Media Matters for America denouncing a new report from the Nongovernmental International Panel on Climate Change (NIPCC). Why would two scientists publicly attack a team of nearly 50 of their peers for creating a peer-reviewed report more than 1,000 pages in length and citing nearly 4,000 peer-reviewed articles? Why would they choose to send their criticism to a Web site notorious for being the source of sound-bites for the Democratic Party and groups on the far left?

The two scientists, Kevin Trenberth with the National Center for Atmospheric Research and Michael Oppenheimer of Princeton University, have long histories of being extremists in the debate over climate change. They speak as advocates for a cause and not as scientists. So we ask journalists and the interested public to weigh their intemperate opinions against the following endorsements of NIPCC from more credible climate scientists. Who is more likely to be right?
