Carbon dioxide averaged nearly 431 ppm in April 2026 (new record high)...

10 years ago April averaged about 408 ppm. Preliminary data from https://gml.noaa.gov/ccgg/trends/mlo.html.

This is really concerning, and it isn’t going away. The longer we wait, the worse the impacts get and the harder they are to address.

Red line graph time series of monthly carbon dioxide abundance from January 1959 through April 2026. There is a seasonal cycle and long-term increasing trend. Current levels of CO2 are at 431 ppm. This is the Keeling Curve graph. A line for CO2 10 years ago is also annotated.
