It is more than a little silly to have a breathlessly-awaited, embargoed report presenting analysis of out-of-date scenarios, but here we are!

How Climate Scenarios Lost Touch With Reality
A failure of self-correction in science has compromised climate science’s ability to provide plausible views of our collective future.
GHGs, California, and the EPA: a golden braid of off-the-rails
The unavoidable conclusions are that the SAFE Vehicle Rule serves no ameliorative purpose because the EPA CO2 endangerment finding has no scientific merit.
Claim: Machine Learning can Detect Anthropogenic Climate Change
According to the big computer we are doomed to suffer ever more damaging weather extremes. But researchers can’t tell us exactly why, because their black box neural net won’t explain…
CMIP6 ECS
It is apparent that those who believe in anthropogenic global warming do not understand the intractable fundamental problem with their climate model approach. They are digging themselves a deeper hole.…
Climate Models: Worse Than Nothing?
Climate modeling has arguably been worse than nothing because false information has been presented as true and “consensus.” Alarmism and disruptive policy activism (forced substitution of inferior energies; challenges to…
Models In Turmoil: Underestimation Of Satellite-Based Cloud-Aerosol Interaction “Hampering Climate Change Projections”
By acting as cloud condensation nuclei (CCN), aerosols act as cloud condensation nuclei and thus can alter cloud properties and precipitation. This influences the Earth’s radiation budget and hence climate…
Climate models fail in key test region
The researchers found that when compared to observations, almost every CMIP5 model fails, no matter whether the multidecadal variability is assumed to be forced or internal. They also found institutional…
GEOCARBSULF
Guest Post by Willis Eschenbach There’s a new open access paper in Nature Magazine, entitled “A tighter constraint on Earth-system sensitivity from long-term temperature and carbon-cycle observations“, by Wong et…
“Major Scientific Breakthrough”…Scientists “Step Closer To Predicting North Atlantic Climate”
A team of scientists believe they’ve made a forecasting breakthrough, suggesting the NAO is in fact highly predictable.
The temperature–CO2 climate connection: an epistemological reappraisal of ice-core messages

Modeling Unreality
Guest Post by Willis Eschenbach In the comments to a previous post of mine, Bob Wentworth made an interesting point. He said that it’s not enough to propound my new…
Thunderstorm World: A Model to Explore Ideas from Willis Eschenbach
I’ve been thinking about some ideas that WUWT contributor Willis Eschenbach (WE) has proposed. In particular, WE has suggested that tropical cumulus clouds and thunderstorms provide a “thermostatic mechanism” that…
New NASA Data Sheds (Sun) Light on Climate Models
The team found that the TSIS-1 data had more energy present in visible light wavelengths and less in the near-infrared wavelengths compared to the older SORCE reconstruction. These differences meant…
An Earth Day Reminder: “Global Warming” is Only ~50% of What Models Predict
The claim by the Biden Administration that climate change has placed us in a moment of “profound crisis” ignores the fact that the energy policy changes being promoted are based…
Current climate model simulations overestimate future sea-level rise
The current climate model simulations, which do not take ocean eddies into account, project that the ocean temperatures around Antarctica are increasing under climate change. The new high-resolution simulation shows…
$10 Million AI Grant to Improve Climate Modelling of Clouds
A Team of Scientists plans to use AI to improve climate modelling of sub-grid scale phenomena such as turbulence and clouds. But there is no reason to think an AI…
The Problem with Climate Models
So it may well be, no, it is likely that once the underlying physics is properly understood, climate models will emerge that produce an ECS value considerably smaller than 1.8C.…
There Are Models And There Are Models
Guest Post by Willis Eschenbach I’m 74, and I’ve been programming computers nearly as long as anyone alive. When I was 15, I’d been reading about computers in pulp science…
Compensation between cloud feedback + ECS and aerosol-cloud forcing in CMIP6 models
The new open-access paper – the senior author of which, Gabriel Vecchi, is a well known professor of geosciences at Princeton University – provides further evidence that high ECS CMIP6…
Junk Grade Models: Even Short-Term Climate And Weather Modelers Get It All Wrong
Reposted from NoTricksZone By P Gosselin on 19. February 2021 Many climate policies are based on scenarios generated by models. Depending what these models churn out, actions and costly regulations get enacted to…
Here comes the new generation of climate models: the future of rainfall in the Alps
Next generation climate models are developed and applied by the CMCC Foundation in several international projects and contexts. Some examples include the study of urban heatwaves and the evolution of…
Climate Model Failure
By Andy May On January 22, 2021, John Christy presented a new online talk to the Irish Climate Science Forum. The talk was arranged by Jim O’Brien. A summary of…
Meet The Team Shaking Up Climate Models
They have gathered some of the brightest experts from around the world to start to build a new, modern climate model. They hope to corral the vast flow of data…
