The prominent climatologist Mike Hulme has slammed the Cook et al 97% "nonsensus" paper in a comment at the Nottingham University Making Science Public blog.
The “97% consensus” article is poorly conceived, poorly designed and poorly executed. It obscures the complexities of the climate issue and it is a sign of the desperately poor level of public and policy debate in this country that the energy minister should cite it. It offers a similar depiction of the world into categories of ‘right’ and ‘wrong’ to that adopted in Anderegg et al.’s 2010 equally poor study in PNAS: dividing publishing climate scientists into ‘believers’ and ‘non-believers’. It seems to me that these people are still living (or wishing to live) in the pre-2009 world of climate change discourse. Haven’t they noticed that public understanding of the climate issue has moved on?
This is an interesting development since nobody is going to finger Hulme as any kind of a sceptic.
