Warmist Kevin Trenberth laments: The next IPCC report will be "blander"; it's now "harder to gain a consensus"; Climategate "made an immense difference"

Climate scientist loses faith in the IPCC

AS THE world's elite global warming experts begin poring over the drafts of the latest Intergovernmental Panel on Climate Change report this week, one leading scientist doesn't believe the process should be happening at all.

''I think it will be less successful than the last assessment, and I think it will be blander - I'm disappointed in what I've seen so far,'' said Kevin Trenberth, the head of the climate analysis section at the US National Centre for Atmospheric Research.
...Dozens of Australian scientists are among hundreds of international experts who started reviewing the IPCC's fifth summary report this week, with the final version to be published next September.

But Professor Trenberth believes too many researchers and too much ''second tier'' science are diluting the report's quality, and that science has jumped far ahead of the lumbering process. ''There are more people, it's more diffuse, it's harder to gain a consensus - quite frankly I find the whole process very depressing,'' he said. ''The science is solid, but with a larger group it's harder to reach a consensus, and updates every six years are just too slow. After the fifth assessment, we should push on with a different format.''

Professor Trenberth is a bruised survivor of the so-called ''climategate'' scandal, which involved the theft and publication of thousands of emails that had been sent between some of the world's most influential climate researchers.

Professor Trenberth believes it had a big impact on public debates about climate science. ''It made an immense difference - the level of vitriol and hate we received,'' he said. ''Not only do we have waves of attacks when we publish and it ends up on a denialist website, but it has affected politicians.''

The US National Oceanic and Atmospheric Administration recently had its climate change-related research budget slashed by a fifth, affecting Professor Trenberth's peers, as a result of online campaigns against climate scientists, he said. He believes uncertainties in climate change models scientists rely upon is being falsely inflated as a general uncertainty about the status of climate science.
