I have been critical of computer models being used to predict the effects of human on the climate. The main reason is that they are always wrong and are nothing more than shit in shout models that are paid for by the Environmental Wacko lobby. Mostly in the universities but also with the government agencies like NASA and NOAA.
These are models that the Environmental Wackos refer to when they tell us we are all going to be dead in seven, or ten or 20 years because of man made warming.
The Climate Change scam research mostly is nothing more than grifting for government grants and a power-grab tool for government itself.
It looks like we have now discovered a main reason the models are always wrong. 40 years of observed data trumps some grad student's computer program, doesn't it?

New Study: Climate Models Get Water Vapor Wildly Wrong – A ‘Major Gap in Our Understanding’
By
Kenneth Richard on 19. February 2024
“Here, we have demonstrated a major discrepancy between observation-based and climate model-based historical trends in near-surface atmospheric water vapor in arid and semi-ari regions.” – Simpson et al.,
A new study published in
PNAS has demonstrated, once again, that climate models fail to simulate what happens in the real world with regard to fundamental climate change variables like water vapor. This is a devastating finding, as water vapor is the most significant greenhouse gas due to its alleged “feedback” capacity, accelerating warming well beyond what CO2 is said to be capable of alone.
The authors do not understate the significance of this climate modeling failure.
“This represents a major gap in our understanding and in climate model fidelity that must be understood and fixed as soon as possible in order to provide reliable hydroclimate projections for arid/semi-arid regions in the coming decades.”
Per state-of-the-art climate models, specific humidity (SH) should increase as a consequence of CO2-induced global warming. But 40 years of observations (1980-) show no increasing SH trend over arid/semi-arid regions.
Per state-of-the-art climate models, relative humidity (RH) should decline slightly as a consequence of CO2-induced global warming. But 40 years of observations (1980-) show not a
slight declining trend, but a declining trend that is “about an order of magnitude more than the models on average.” In other words, the climate models are wrong by a factor of 10
The models say the tropical warming rate should have been nearly 3 times larger than the observations show – “0.389 ± 0.173°C per decade (models) and 0.142 ± 0.115°C per decade (observed)” – due to the assumed feedback response to CO2 forcing over warm regions. Instead, there is a “clear and significant tendency on the part of the models to overstate warming.”
