USA Today’s readers deserve better than speculative headlines built on hypothetical futures. They deserve reporting grounded in observed data, historical context, and the recognition that climate models are tools for…

New Study: NASA’s Models Wildly Underestimate The Capacity Of Clouds To Alter Solar Radiation
Today’s climate models are so inaccurate they must be improved a hundredfold just to detect a CO2 signal in climate change.
The Model That Works
Guest Post by Willis Eschenbach (@WEschenbach at X, my own blog is here.) I’d like to take a moment to discuss some implications of my peer-reviewed paper about my implementation…
Unverified and Unvalidated
Guest Post by Willis Eschenbach (@WEschenbach on X, my personal blog is here) Dear friends, pull up a chair and pour a good strong coffee. Because today’s topic is a…
Are Climate Models “Just Physics”?
…any policy can only benefit from a better understanding of how climate models are constructed, their physical basis, how they can be tested, and how to assess their outputs.
SSP5-8.5: Garbage In, Doomcasting Out
Guest Post by Willis Eschenbach (@WEschenbach on X, and my blog is here.) You might have read about RCP8.5, which is now called SSP5-8.5. It is the most extreme future…
Shocked Silence Greets RCP8.5 Demise as ‘Implausibility’ Ruling Leaves Net Zero Fearmongering in Tatters
The fallout from the recent Intergovernmental Panel on Climate Change (IPCC) ruling that computer model high emissions pathway RCP8.5 is “implausible” is only just beginning.
RIP Doomsday Model RCP8.5 – A Quiet but Profound Shift in Climate Science
RCP8.5 is mostly dead, let’s hope it becomes truly dead.
Climate Models Discover Yet Another Thing CO2 Can Do
So now the story becomes: CO₂ causes warming globally, except where it causes cooling, except when it doesn’t, depending on season, topography, moisture availability, and circulation patterns.
British Intelligence Goes Full Guardian Promoting Untestable Computer-Generated Scares of Eco-System Collapse
This ridiculous scare alone gives us an idea about what is going on here. Humans affect the environment they live in, as do all species, but political extremists are given…
Ross McKitrick on Climate Models, Economic Impacts, and the DOE Report
In this in-depth interview, economist and statistician Ross McKitrick discusses climate models, uncertainty, and whether the public climate debate is as scientifically balanced as often claimed. He also reflects on…
Tropical Tropospheric Temperature Trends, 1979-2025: The Epic Climate Model Failure Continues
Maybe if the modelers figured out why their handling of moist convection is flawed, models would then produce warming more in line with observations, and more in line with each…
Surface Air Temperature Trends, Climate Models vs Observations, 1979-2025
This is just a short update regarding how global surface air temperature (Tsfc) trends are tracking 34 CMIP6 climate models through 2025. The following plot shows the Tsfc trends, 1979-2025,…
Aussie Climate Scientists Demand Their Own Energy Guzzling Supercomputer
… making good decisions about Australia’s future requires us to be self-sufficient …
Thought Experiment: Could NCAR’s “Derecho” Climate Supercomputer Earn Its Keep as a Bitcoin Miner?
I started a little thought experiment to find out whether the facility could earn some cash if it were converted to Bitcoin mining.
Just How Good Were the Early Climate Models?
The take-home message? If early climate models missed any of these supposed climate novelties, climate modeling wouldn’t have gotten off the ground. What early climate modeling showed was that the…
When Climate Modeling Becomes Climate Mythmaking: “Sea-Level Rise Causes More Cold Snaps”
The modern climate discourse is full of surprises, but every so often a publication appears that manages to outdo even the most ambitious attempts at connecting loosely related climate variables.
A Submission to the Australian Senate Investigation into Climate Misinformation
I find it quite distressing that ideas stemming from genuine mathematical and scientific analyses that cast doubt on the mainstream climate message are routinely dismissed as misinformation, when much of…
From Weather to Climate: Why Tribune’s News Service AI Leap is a Logic Fail
Tribune News Service: please stop confusing flash with substance. AI is not a magical oracle of climate truth.
