Carbon Dioxide Set an All-Time Monthly H

Carbon Dioxide Set an All-Time Monthly High

(With May in the books, it’s official: carbon dioxide set an all-time monthly record. It’s a sobering annual reminder that humans are pushing the climate into a state unseen in millions of years.
Carbon dioxide peaked at 409.65 parts per million for the year, according to data from the National Oceanic and Atmospheric Administration. It’s not a surprise that it happened. Carbon dioxide levels at Mauna Loa Observatory in Hawaii peak in May every year.)
