In February 2022, our planet was 1.19°C warmer than the pre-industrial temperature of 13.7°C calculated from the collected global records in the 1880s. The Industrial Revolution technically began about 100 years earlier, but no extensive measurements exist to verify the combined surface temperature of both land and water during those years. Between 1920 and 1940, the global temperature rose 0.1°C per decade, 0.2°C during the 1980s, and 0.61°C per decade since 2000. This ascending trajectory corresponds to a rise in atmospheric carbon dioxide concentrations from about 280 parts per million to about 420 ppm, and ends the 10,000 years of relative climate stability that has allowed human civilization to flourish.
