(Reuters) - A key measure of carbon dioxide emissions in the Earth's atmosphere hit a record in May even as a global pandemic brought the world's economies to a virtual standstill this year, according to U.S. government data published on Thursday.
Carbon dioxide recorded at the Mauna Loa Observatory in Hawaii reached 417 parts per million (ppm) in May, higher than the record of 414.8 ppm set last year, according to the announcement by the National Oceanic and Atmospheric Administration and the Scripps Institution of Oceanography at the University of California San Diego.
