Challenging the Mathematical Basis of General Circulation Models

His framework invariably ensures well-posed reduced systems for limited domains and has broader applicability, including mesoscale and equatorial atmospheric behaviors, oceanic dynamics, and plasma physics.

Do CMIP5 models skillfully match actual warming?

CMIP5 models have not been at all skillful in predicting future warming; they have matched the illustrated 1970–2020 observed warming (which was past rather than future warming until the late 2000s, when CMIP5 models…

German Scientists: Global Warming A “Corrupt”, Fear-Mongering Scheme “Headed By Super-Rich”

We need an uprising of the decent against this fraudulent business model of alleged climate rescue.

SITYS: Climate Models do not Conserve Mass or Energy

…the atmospheric moisture budget is relatively large (and worse for CMIP6), approaching/exceeding the magnitude of current trends for many models.

The Great Climate Change Science Bottleneck

IAM research and IPCC reporting The two activities have become interdependent and reciprocally legitimizing.

Climate Modelling in Australia

The current ACCESS model clearly produces unphysical nonsense.

Is the Arctic September Sea Ice Doomed to Disappear in the 2030’s?

K23 takes advantage of the rejected CMIP 6 MMM and comes to strongly biased results. It’s overdue for the editorial board of “Nature communication” to check the peer review process…

Sun, Temperatures, and Models

Guest Post by Willis Eschenbach PART THE FIRST – REAL WORLD Well, my monkey mind started thinking about the relationship between how much sunshine is absorbed at the surface and…

Epic Fail in America’s Heartland: Climate Models Greatly Overestimate Corn Belt Warming

My continuing theme has been, “don’t believe gloom and doom forecasts for the future of the U.S. Corn Belt”.

Climate Computer Games

…when confirmation bias distorts the search for truth, the outcome is the “climate change” hyperbole and “saving-the-planet” activism that is now disrupting every aspect of our lives.    

Introducing the Realitometer

Month by inexorable month, the Realitometer will show just how absurdly exaggerated were and are the official predictions of global warming on which easily-manipulated governments

Dueling ITCZs

Guest Post by Willis Eschenbach Inspired by a comment about modeled rainfall by Dr. Richard Betts over in the Twitterverse, I decided today to look at how well the climate…

Ross McKitrick: The important climate study you won’t hear about

…the atmosphere has warmed at half the average rate predicted by climate models over the same period.

More on Cloud Reduction.  CO2 is innocent but Clouds are guilty.

Statistical uncertainty in the CERES and Cloud data seem to retard acceptance of alternative GW theories.

Claim: Deep ocean currents around Antarctica headed for collapse, study finds

“We are talking about the possible long-term extinction of an iconic water mass,” says Prof England.

Claim: Arctic Climate Modelling Too Conservative

[It’s been a while since we’ve had a good “It’s Worse Than We Thought” story~cr] UNIVERSITY OF GOTHENBURG Climate models used by the UN’s IPCC and others to project climate…

The Models Are OK, the Predictions Are Wrong | Dr. Judith Curry | EP 329

Dr Jordan B Peterson and Dr. Judith Curry discuss climate change, the major error in current models and future predictions, academic fraud, and the need for dissenting opinions.

AIs Trained on Climate Models Predict Faster Warming

Why did they train the AI initially using climate models? Why not ignore the models, and directly use the observations to directly train the AIs?

Monash Professor: Climate Change Driven Bushfires will Kill 2412 Aussies in the Next Decade

The researchers appear to be effectively predicting five events of the same severity as Australia’s 2019-20 “Black Summer”, over the next seven years.

Claim: Skiing over Christmas holidays no longer guaranteed – even with snow guns

Current climate models predict that there will be more precipitation in winter in the coming decades, but that it will fall as rain instead of snow.
