evidence: The blue curve shows the actual raw (measured) values. [...] This graph shows the U.S. Lower 48 average mean temperature from 1895 to 2023. The blue curve shows the actual raw (measured) values. The red curve shows the reported or adjusted values. The actual thermometer data indicate that there has been little warming in the CONUS since 1895. Top 10 warmest years by raw data: 1. 2012 2. 1921 3. 1931 4. 1934 5. 1998 6. 2016 7. 1953 8. 1938 9. 1939 10. 2015 Pretty much all of the climate warming results from significant adjustments, to the data, most of which are due to the supposed "Time of Observation Bias" (TOBS). Essentially, government scientists think that hot days were double counted in the past because COOP station observers were too stupid to reset their min / max thermometers before they went to bed. If that were actually the case, it’d be a problem, but it would’ve been obvious right away to any station observer how these thermometers worked in a few days’ of using them. TOBS adjustments are based on assumptions that don’t have any basis in reality. That’s why the adjusted temperature data shouldn’t be used. I’m all for quality control, but the way in which thermometer data has been handled by bureaucrats is abhorrent.
