“Colorful fluid dynamics” and overconfidence in global climate models
by David Young This post lays out in fairly complete detail some basic facts about Computational Fluid Dynamics (CFD) modeling. This technology is the core of all general circulation models of the atmosphere and oceans, and hence global climate models … Continue reading

The IPCC’s attribution methodology is fundamentally flawed
by Ross McKitrick One day after the IPCC released the AR6 I published a paper in Climate Dynamics showing that their “Optimal Fingerprinting” methodology on which they have long relied for attributing climate change to greenhouse gases is seriously flawed … Continue reading

What’s the worst case? A possibilistic approach
by Judith Curry Are all of the ‘worst-case’ climate scenarios and outcomes described in assessment reports, journal publications and the media plausible? Are some of these outcomes impossible? On the other hand, are there unexplored worst-case scenarios that we have … Continue reading
