According to the authors of a study, if we don’t mend our wicked ways, in 500 years people in India will have to wear space suits when they want to…

IPCC Model Scenarios Compared To Actual Measured Temperatures
In an effort to hold the IPCC accountable, I have compared actual measured temperatures with two of their scenarios from the AR4 report in 2007. The B1 and A2 scenarios.…
Can Arctic warming (be) linked to colder winters?
The causes of the extreme winter weather in the USA remain unknown, apart from the obvious reason: the Polar Vortex. The reasons put forward in the above Nature paper are…
Warming and Drying part 2 Natural Cycles, Climate see-saws and failed models
Natural cycles like the Madden Julian Oscillation and the El Nino Southern Oscillation cause regions of rising moist air and precipitation varying with regions of sinking cloudless dry air that…
New Confirmation that Climate Models Overstate Atmospheric Warming
Two new peer-reviewed papers from independent teams confirm that climate models overstate atmospheric warming and the problem has gotten worse over time, not better.
Fussing Over One Degree of Simulation
Allowing some historical perspective shows that the IPCC is wrong to label the recent temperature changes ‘unprecedented’. They are not unusual in magnitude, direction or rate of change, which should…
Why the IPCC focuses on the scenarios that it does
It is more than a little silly to have a breathlessly-awaited, embargoed report presenting analysis of out-of-date scenarios, but here we are!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…
