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 from global warming absorbed in the Oceans – like a big charging battery, contributing to increased rates of ice melt around the world, ie. the ice sheets in Antarctica, causes Ocean waters to expand – sea level rise, and drives coral bleaching.
This is the first time in human history our planet's atmosphere has had more than 415ppm CO2.

Not just in recorded history, not just since the invention of agriculture 10,000 years ago. Since before modern humans existed millions of years ago.
We don't know a planet like this. https://t.co/azVukskDWr
