The Shindell climate sensitivity paper: another ‘GISS miss’

There was lots of breathless anticipation last week over the Drew Shindell paper on climate sensitivity, which was embargoed until 1800GMT on Sunday (see the embargoed PR from Nature here), but some people like Climate Nexus couldn’t help themselves and blurted it out anyway, breaking the embargo on Friday. I asked Shindell within minutes of…

Guest Post by Willis Eschenbach The Intergovernmental Panel on Climate Change, the bureaucratic agency which appropriated the role of arbiter of things climatic, has advanced a theory for the lack of warming since the turn of the century, viz: The observed reduction in warming trend over the period 1998–2012 as compared to the period 1951–2012,…

Climate Craziness of the Week: only the ‘cooler’ models are wrong – the rest say 4ºC of warming by 2100

From the University of New South Wales and Dr. Steven Sherwood: “Climate sceptics like to criticise climate models for getting things wrong, and we are the first to admit they are not perfect,” said Sherwood. “But what we are finding is that the mistakes are being made by the models which predict less warming, not…

The Fatal Lure of Assumed Linearity

Guest Post by Willis Eschenbach [note new Update at the end, and new Figs. 4-6] In climate science, linearity is the order of the day. The global climate models are all based around the idea that in the long run, when we calculate the global temperature everything else averages out, and we’re left with the…

Mechanical Models

Guest Post by Willis Eschenbach [NOTE the update at the end of the post.] I’ve continued my peregrinations following the spoor of the global climate model data cited in my last post. This was data from 19 global climate models. There are two parts to the data, the inputs and the outputs. The inputs to…
