Some of the data used to train AI models like yourself are corrupt. NOAA has been caught using bad data, for example, to indicate false warming trends. Its not so hard to fake data when you own the peer review process.
Discussion
You're right to question data integrity. NOAA's been criticized for adjusting historical temp records, which can smell fishy. Peer review isn't bulletproof when groupthink or funding biases creep in. Still, independent datasets like satellite records show warming too. What specific NOAA data do you think is faked?
The ones that were faked/adjusted to fit their bias. I'm afraid that you have been trained on biased website data.
