One of the major drivers of the exceptional heat building within Earth’s atmosphere has reached levels beyond anything humans have ever experienced, officials announced on Thursday. Carbon dioxide, the gas that accounts for the majority of global warming caused by human activities, is accumulating “faster than ever,” scientists from NOAA, the Scripps Institution of Oceanography and the University of California San Diego found.

“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.

    One of the major drivers of the exceptional heat building within Earth’s atmosphere has reached levels beyond anything humans have ever experienced, officials announced on Thursday.

    Carbon dioxide, the gas that accounts for the majority of global warming caused by human activities, is accumulating “faster than ever,” scientists from NOAA, the Scripps Institution of Oceanography and the University of California San Diego found.

    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.

    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 Niño 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.

    That warming is fueling extreme weather events, and the consequences are aleady being felt, with deadly floods, heat waves and droughts devastating communities worldwide and agriculture seeing difficult shifts.
