A new study using 60 million daily maximum/minimum temperatures from 1,600 global weather stations across 29 countries indicates the globe warmed at a rate of 0.022°C/yr from 1899 to 1940, 42 years when cumulative CO2 emissions only amounted to 139.6 GtC. [some emphasis, links added]
Then, over the next 42 years (1941-1982), global temperatures cooled at a rate of -0.011°C/yr even though cumulative CO2 emissions rose to 460.0 GtC.
In other words, CO2 emission rates more than tripled from the 1940s to the 1980s as global temperatures declined.
Global warming returned in the 1980s.
However, over the next 42 years (1983-2024), the warming rate of 0.017°C/yr was not as strong as it was in the early 20th century.
This slower rate of warming is significant because cumulative CO2 emissions were 1,209.8 GtC during this most recent period, an amount 8.6 times higher than they were from 1899-1940.
In other words, over the past 125 years of “global warming,” no decade has experienced a warming or cooling period that aligned with the varying rates of human-caused CO2 emissions.
“These findings challenge the conventional assumption that human-induced CO2 is the primary driver of global warming.”

Looking at a period of longer than 125 years, there is a preponderance of data that carbon dioxide is not controlling the Earth’s temperature. There was the roman warm period, medieval warm period, and mini ice age that all occurred without significant changes in carbon dioxide concentrations. The dust bowl in the United States occurred before carbon dioxide was considered a significant factor. This was part of a world wide phenomenon. There were also impacts in parts of Europe and Asia. Australia had severe drought and heat at that time. They didn’t have severe heat but at this time South America and Africa had severe drought. At the beginning of this century we had a pause in warming despite carbon dioxide levels being high and raising rapidly.
However, to support the trillion dollar climate industrial complex, the UN giveaways, and taxes like Hawaii’s 11% cruise tax, it is critical that CO2 be assigned as the major factor controlling the Earth’s temperature. For that reason we can be sure that the media stooges and junk scientist will continue to push the carbon dioxide narrative.
