CO2 just hit an all-time record. But that’s not the worst of it.

The rapid rise continues, relentlessly.

The Scripps Institution of Oceanography and the National Oceanic and Atmospheric Administration (NOAA) announced Tuesday that the average carbon dioxide concentration in the atmosphere during May rounded to 414.8 parts per million, or ppm — the highest monthly number on record and the peak of 2019. While Earth’s CO2 trend has been skyrocketing overall — compared to both geologic and historic levels — each year the potent greenhouse gas wavers down during the warm growing season, when flourishing trees and plants in the Northern Hemisphere temporarily soak up CO2 from the air (this ever-rising, though saw-like line is called the Keeling Curve)…

…Yet, in the last year, it was a 3.5 ppm gain. Concentrations of the planet’s most influential greenhouse gas are accelerating.

“It’s extremely alarming to see atmospheric CO2 continuing to increase relentlessly year after year when all scenarios that lead to a stable climate require that it go down,” said Sarah Green, an environmental chemist at Michigan Technological University.
