Carbon Dioxide Levels Soared Above 412 Parts Per Million in 2020, Highest in Human History
------------------------------------------------------------------------------------------

In climate news, the National Oceanic and Atmospheric Administration
reports atmospheric levels of carbon dioxide reached their highest
levels in human history last year, averaging more than 412 parts per
million. That's despite a modest slowdown in emissions due to the
coronavirus pandemic in 2020. NOAA also reports global average sea level
rose to a new record high, about 3.6 inches above 1993 levels, when
satellite measurements began.
