Carbon Dioxide Levels In the Atmosphere Are Surging 'Faster Than Ever,' Report Finds

Carbon dioxide levels in Earth's atmosphere are accumulating "faster than ever" and have reached unprecedented levels, with a peak of 426.9 ppm recorded at NOAA's Mauna Loa Observatory in May 2024, said scientists from NOAA, the Scripps Institution of Oceanography and the University of California San Diego. CBS News reports: "Over the past year, we've experienced the hottest year on record, the hottest ocean temperatures on record, and a seemingly endless string of heat waves, droughts, floods, wildfires and storms," NOAA Administrator Rick Spinrad said in a press release. "Now we are finding that atmospheric CO2 levels are increasing faster than ever." The researchers measured carbon dioxide, or CO2, levels at the Mauna Loa Atmospheric Baseline Observatory. They found that atmospheric levels of the gas hit a seasonal peak of just under 427 parts per million in May -- an increase of 2.9 ppm since May 2023 and the fifth-largest annual growth in 50 years of data recording. It also made official that the past two years saw the largest jump in the May peak -- when CO2 levels are at their highest in the Northern Hemisphere. John Miller, a NOAA carbon cycle scientist, said that the jump likely stems from the continuous rampant burning of fossil fuels as well as El Nino conditions making the planet's ability to absorb CO2 more difficult. 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 the Industrial Revolution. However, NOAA noted that their observations were taken at the observatory specifically, and do not "capture the changes of CO2 across the globe," although global measurements have proven consistent without those at Mauna Loa. "Not only is CO2 now at the highest level in millions of years, it is also rising faster than ever," Ralph Keeling, director of Scripps' CO2 program, said in the release. "Each year achieves a higher maximum due to fossil-fuel burning, which releases pollution in the form of carbon dioxide into the atmosphere. Fossil fuel pollution just keeps building up, much like trash in a landfill." "We are living in unprecedented times. ... This string of hottest months will be remembered as comparatively cold," Carlo Buontempo, director of Copernicus, added.
