The surge of carbon dioxide levels at the measuring station surpassed even the global average set last year, which was a record high of 419.3 ppm — 50% higher than it was before

Carbon dioxide is accumulating in the atmosphere faster than ever—accelerating on a steep rise to levels far above any experienced during human existence, scientists from NOAA and the Scripps Institution of Oceanography at the University of California San Diego announced today.

Hawaii's Mauna Loa Observatory is home to the longest-running records of measuring CO₂ in our atmosphere with records dating back to 1958.

Levels of planet-heating carbon dioxide gas in the atmosphere are rising “faster than ever,” according to a report published Thursday. That spells serious disruption for the climate in decades to

Carbon dioxide is accumulating in the atmosphere faster than ever — accelerating on a steep rise to levels far above any experienced during human existence, scientists from NOAA and Scripps Institution of Oceanography announced Thursday.

Atmospheric carbon dioxide concentration at the Mona Loa Atmospheric Baseline Observatory has increased more rapidly between January and April 2024 than the first four months of any year, according to NOAA.
