Earth Atmosphere Contains 415ppm CO2

Measurements at Mauna Loa by the Scripps Institution of Oceanography recorded 415.50ppm carbon dioxide CO2 concentration in the atmosphere for the first time in millions of years. This includes humans who evolved with around 280ppm. Temperature follows CO2, thus as additional carbon pollution is heating the atmosphere, with about 90% of this extra energy accumulated…
