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…

One Step Forward, Two Steps Back

Guest Post by Willis Eschenbach David Rose has posted this , from the unreleased IPCC Fifth Assessment Report (AR5): ‘ECS is likely in the range 1.5C to 4.5C… The lower limit of the assessed likely range is thus less than the 2C in the [2007 report], reflecting the evidence from new studies.’ SOURCE I cracked up…
