“The rise in atmospheric carbon dioxide levels is relentless, and this means the costs of climate change to humans and the planet continue to rise relentlessly as well," said University of Michigan environment dean Jonathan Overpeck.

Carbon dioxide can stay in the air for centuries, so the short-term reductions of new carbon pollution for a few months didn't have much of a big picture effect, said NOAA senior scientist Pieter Tans.

Measurements of carbon dioxide, the chief greenhouse gas, averaged 417.1 parts per million at Mauna Loa, Hawaii, for the month of May, when carbon levels in the air peak, the National Oceanic and Atmospheric Administration said.

Heat-trapping carbon dioxide in air hits new record high New measurements show carbon pollution levels in the air hit another record in May By SETH BORENSTEIN AP Science Writer June 4, 2020, 10:35 PM 2 min read 2 min read Share to FacebookEmail this article KENSINGTON, Maryland -- The world hit another new record high for heat-trapping carbon dioxide in the atmosphere, despite reduced emissions because of the coronavirus pandemic, scientists announced Thursday.

Carbon dioxide levels peak in May because starting in late May, because growing plants suck up more of heat-trapping gas, causing carbon amounts in the air to drop, Tans said.
