Ignorant Skeptics?: UN Scientist Prof. Trenberth says only ‘poorly informed’ scientists disagree with UN – Appeals to Authority: ‘The IPCC has spoken’
Climate Depot Editorial
Dr. Kevin Trenberth — head of the Climate Analysis Section at the National Center for Atmospheric Research, in Boulder CO and a UN IPCC lead author, claimed dissenting scientists were ignorant of the science behind man-made global warming. Trenberth also declared the debate over and wrote ‘the IPCC has spoken.”
“I have found that the only scientists who disagree with the IPCC report are those who have not read it and are poorly informed,” Trenberth, declared in an October 10, 2009 written debate with Hurricane guru Dr. Bill Gray, Professor Emeritus of Atmospheric Science at Colorado State University.

The ‘IPCC HAS SPOKEN”
Trenberth appealed to authority in order to convince readers that man-made climate change was a threat to mankind.
“The Intergovernmental Panel on Climate Change has spoken: ‘Warming of the climate system is unequivocal’ and it is ‘very likely’ due to human activities,” Trenberth asserted.
Trenberth also claimed that the “IPCC process is very open.” Trenberth also added his own policy prescriptions to address global warming. “There is much that can be done, and America should lead. If done in the right way, benefits to the climate through reduced emissions save energy and promote the economy, while increasing sustainability,” he expalained.
Back in 2007, Trenberth surprised many with his candid comments about climate models. He admitted that the climate models touted by former Vice President Al Gore, the UN, the media and scientists are not predictions, but merely “story lines.”Climate Depot Response to Trenberth’s claim that only ‘poorly informed’ scientists disagree with UN IPCC’s spoken word.
“In fact there are no predictions by IPCC at all. And there never have been. The IPCC instead proffers ‘what if’ projections of future climate that correspond to certain emissions scenarios,” Trenberth wrote in journal Nature’s blog on June 4, 2007. Trenberth also admitted that the climate models have major shortcomings because “they do not consider many things like the recovery of the ozone layer, for instance, or observed trends in forcing agents. There is no estimate, even probabilistically, as to the likelihood of any emissions scenario and no best guess.” (LINK)
Climate Depot Responds
The simplest way to respond to Trenberth’s assertion is to let the latest scientific data, peer-reviewed studies and the UN’s own IPCC scientists speak for …
