AP / World leaders have been meeting for 29 years to try to curb global warming, and in that time Earth has become a much hotter and deadlier planet.

Carbon dioxide levels have increased 17% from 353 parts per million in September 1992 to 413 in September 2021, according to NOAA. The agency’s annual greenhouse gas index, which charts six gases and weights them according to how much heat they trap, rose almost 20% since 1992.

From 1993 to 2019, the world put more than 885 billion tons (803 billion metric tons) of carbon dioxide in the air from the burning of fossil fuels and making of cement, according to the Global Carbon Project, a group of scientists who track emissions.
