~426.0 ppm: September average of atmospheric CO2 at Mauna Loa, estimated from daily values. That's another ~1.7 ppm higher than last year.
September is the lowest point in the seasonal cycle, and we won't see a value this low (but extremely high) for many generations to come.

Can you guess the next post in this thread? It's unfortunately somewhat repetitive.

@Sustainable2050@mastodon.energy Actually, an annual increase of 1.7 ppm would be the smallest change in a while. It might have something to do with the El Niño https://gml.noaa.gov/ccgg/trends/gr.html
