Pretty freaking amazing. I can't see us avoiding at least 500ppm within within the next 80 to 100 years.Carbon dioxide levels measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked at 424 parts per million in May, continuing a steady climb further into territory not seen for millions of years, scientists from NOAA and Scripps Institution of Oceanography offsite link at the University of California San Diego announced today.
Measurements of carbon dioxide (CO2) obtained by NOAA’s Global Monitoring Laboratory averaged 424.0 parts per million (ppm) in May, the month when CO2 peaks in the Northern Hemisphere. That is an increase of 3.0 ppm over May 2022, and represents the fourth-largest annual increases in the peak of the Keeling Curve in NOAA’s record. Scientists at Scripps, which maintains an independent record, calculated a May monthly average of 423.78 ppm , also a 3.0 ppm increase over their May 2022 average.
Carbon dioxide levels are now more than 50% higher than they were before the onset of the industrial era.
