The South Pole’s CO2 Levels at Highest Levels in 4 Million Years

The Earth passed another unfortunate milestone May 23 when carbon dioxide (CO2) surpassed 400 parts per million (ppm) at the South Pole for the first time in 4 million years.

The South Pole has shown the same, relentless upward trend in CO2 as the rest of world, but its remote location means it’s the last to register the impacts of increasing emissions from fossil fuel consumption, the primary driver of greenhouse gas pollution.
