The last time the concentration of Earth’s main greenhouse gas reached 400 ppm, the Arctic was ice-free and sea levels were many meters higher.

Earlier this month, a long-anticipated climate milestone was measured in Hawaii: The last time the concentration of Earth’s main greenhouse gas reached 400 ppm, the Arctic was ice-free and sea levels were over 10 meter higher.

“With 400 ppm CO2 in the atmosphere, we have crossed an historic threshold and entered a new danger zone. The world must wake up and take note of what this means for human security, human welfare and economic development.”

Executive Secretary of the UN Framework Convention on Climate Change Christiana Figueres
