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…

A Sea Change for Climate Science?

By David Stockwell writing in Quadrant Online As CO2 climate models falter and even the IPCC backs off its estimates, it just may be that a radical shift in thinking is looming. Wouldn’t it be funny if it was the sun all along? Remember Thomas Kuhn and his paradigm shift?  According to his Structure of…

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…

More low climate sensitivity

This paper A lower and more constrained estimate of climate sensitivity using updated observations and detailed radiative forcing time series from Skeie et al is now in open peer review at Earth System Dynamics. They say an ECS of 1.84 See Figure E2 from the paper.
