Reached a peak of 417.1 parts per million, 2.4 more than the record of May 2019
To anticipate the news that carbon dioxide levels in the atmosphere have risen to a new peak despite the impact of the lockdowns and the drop in transport imposed by the coronavirus crisis, it was the Guardian.
Without the blockades imposed to slow the spread of Covid-19, the increase could have been greater, according to Ralph Keeling, professor of the Scripps Institution of Oceanography. “People may be surprised” by these data, he stressed: “The crisis has slowed emissions, but not enough to appear clearly to Mauna Loa.”
Meanwhile, globally, the month of May 2020 was also the hottest ever with temperatures of 0.63 degrees centigrade above the average for the same month between 1981 and 2010. The highest temperatures were recorded in some areas of Siberia (even 10 degrees above average), Alaska and Antarctica. In Europe, however, May recorded lower temperatures than the average, but with a clear geographical division. The Copernicus Climate Change Service climate bulletin notes.
