In 2026, we will see multiple months at or above 430 ppm. By 2027. we will never see a monthly reading at or below 430 ppm again.

Oh, fun fact to remember - each ppm is 2.13 billion tons of carbon.

Where will be able to get our climate information from? Mountain Mule Apr 2025 #2

Yes, it does. Scripps also tracks trace gases, but again, likely some federal funding needed . . . hatrack Apr 2025 #3
