Det här visar cirkelresonemanget väldigt tydligt:Nasa skriver om havstemperaturen

“That long-term trend is almost entirely attributable to human forcing—the fact that we've put such a huge amount of greenhouse gas in the atmosphere since the start of the industrial era.”
The map above shows sea surface temperature anomalies on August 21, 2023, when many areas were more than 3°C (5.4°F) warmer than normal.
“Over the long term, we’re seeing more heat and warmer sea surface temperatures pretty much everywhere,” said Gavin Schmidt, the director of NASA’s Goddard Institute for Space Studies.
“There are a lot of things that affect the world’s sea surface temperatures, but two main factors have pushed them to record heights,” said Josh Willis, an oceanographer at NASA’s Jet Propulsion Laboratory (JPL). “We have an El Niño developing in the Pacific, and that’s on top of long-term global warming that has been pushing ocean temperatures steadily upward almost everywhere for a century.”

Det finns flera exempel i tråden på olika forskare som påtalar detta.
Genom att föra ett resonemang som hela tiden leder tillbaka till resultaten från dessa otillräckliga modeller så uppstår ett cirkelresonemang av typen: ”Modellerna visar att uppvärmningen beror på människans utsläpp – alltså är det så.”
I verkligheten kan givetvis uppvärmningen även drivas av sådana faktorer som inte ingår i modellerna.
