Climate modeler Matthew England still ignoring reality – claims IPCC models will eventually win
From the University of New South Wales and ‘models versus reality‘ department comes this claim from alarmist Matthew England, whose “say anything” track record isn’t at all impressive, and looks…
Study: Global Warming Actually More Moderate Than Worst-Case IPCC Models
From Duke University, where they validate what we’ve been saying for quite some time: there’s a divergence between climate models and reality. Global warming progressing at moderate rate, empirical data…
A reply to Born: How to represent temperature feedbacks in a simple model
By Christopher Monckton of Brenchley, David Legates, Willie Soon and Matt Briggs Mr. Born has had another go at our paper Why models run hot, published in January 2015 (PDF…
Models overestimate 60 year decadal trends
Guest essay by Clive Best Marotzke & Forster(2015) found that 60 year trends in global surface temperatures are dominated by underlying climate physics. However, the data show that climate models overestimate such…

Whoops! Study shows huge basic errors found in CMIP5 climate models
It was just yesterday that we highlighted this unrealistic claim from CMIP5 models: Laughable modeling study claims: in the middle of ‘the pause’, ‘climate is starting to change faster’. Now…
Mann's meme generator, from 'false hockey sticks' to 'false pauses'
Bob Tisdale has already effectively dealt a death-blow to Michael Mann’s claims, here: On Steinman et al. (2015) – Michael Mann and Company Redefine Multidecadal Variability And Wind Up Illustrating…
