UN agency: CO2 levels hit record high last year, causing more extreme weather

1. Growth rates of CO2 have accelerated from 2.4 ppm/year from 2011-2020 to 3.5 ppm/year in 2023-2024

Growth rates of CO2 have accelerated from an annual average increase of 2.4 parts per million per year in the decade from 2011 to 2020, to 3.5 ppm from 2023 to 2024, it said.

Bill Hare, the founder of research organization Climate Analytics, called the new data “alarming and worrying.”

Even though fossil fuel emissions were “relatively flat” last year, he said, the report appeared to show an accelerating increase of CO2 in the atmosphere, “signaling a positive feedback from burning forests and warming oceans driven by record global temperatures.”
