Carbon dioxide (CO₂) averaged about 429 ppm in February 2026. Note that I also just updated my annual mean growth rate plot for 2025 on my personal climate indicators website.
10 years ago February averaged about 404 ppm.

@ZLabe I remember when it was 325ppm…. We did have issues properly measuring it back then as a reliable bulk number.
I never thought it would get this high. But I am an optimist and have some remaining hope. I do also have a sick sense of humor. 🤪

Looks like we had a lower growth rate in 2025 as compared to 23 and 24. What would account for that?

@sleepy62 I am not entirely sure, though it is likely related to being a La Nina year, which typically has slower CO2 annual growth.

@ZLabe You can see where it slowed in th 1990s then everything went wrong in the 2000s.
