NOAA: Carbon dioxide levels highest they've ever been over past 3M years
Pandemic shutdowns seem to have not had the positive environmental effect many had hoped for.
The National Oceanic and Atmospheric Administration says carbon dioxide and methane levels actually surged last year.
The CO2 numbers hit the highest recorded level in over 3 million years, despite the closing of businesses and people staying home during the pandemic.
NOAA says CO2 levels hit 412.5 parts per million in 2020, a rise of 2.6 parts per million from 2019.
