A new study analyzed daily temperatures from 992 long-running weather stations across 29 countries covering the years 1899 to 2024.
Then it compared those temperatures to cumulative human CO2 emissions.
They don't match.
From 1899 to 1940, the planet warmed at a rate of 0.022 C per year, even though emissions were low.
Then from 1941 to 1982, temperatures cooled, despite CO2 emissions more than tripling.
From 1983 to 2024, warming returned, but slower than before, at a rate of 0.017 C per year, even as emissions rose 8.6 times higher than during the earlier warming phase.
As the author concludes, "These findings challenge the conventional assumption that human-induced CO2 is the primary driver of global warming."
