alt Hacker NewsFrom 1980 -> 1990 the CO2 mole fraction (ppm) rose 20pts. from ~340 to ~360.
From 2022 -> 2025 the CO2 mole fraction (ppm) rose 10pts. from ~416 to ~426.
It seems we'll have the ppm rise 10pts. in 6 years, which is 40% faster than 40 years ago, which seems like an insane increase to me; almost like things are getting MUCH worse not better.
why did you use 2 different time scales? why not 10 or 3 years for both? What is the 10 year increase 2015 to 2025?
edit: I looked up the answer to my question. NOAA reported 25 ppm increase 2015 to 2025, from 400 parts per million (ppm) to over 425 ppm. (A 25% increase from 1980s)
NOAA has nice charts of ppm growth rate by year and decade https://gml.noaa.gov/ccgg/trends/gr.html
