The atmospheric carbon dioxide level for March was 411.97 parts per million and Continue To Rise. It has now reached levels in the atmosphere not seen in 3 million years.

That’s an increase of 46% from just before the Industrial Revolution in the 1800s, when CO2 levels were around 280 parts per million. Levels began to rise when humans began to burn large amounts of fossil fuels to run factories and heat homes, releasing CO2 and other greenhouse gasses into the atmosphere.  Scientists say to keep a livable planet, we need to cut the level to 350 parts per million.
