The image shows the cumulated carbon dioxide (CO2) emissions by human activities from 1850 till 2025, and the thresholds of CO2 emissions corresponding to global temperature changes of 1.5 °C and 2 °C. Every ton of CO2 emitted by human activities increases global temperature for millennia to come ( https://www.nature.com/articles/nclimate2923 ).
