Atmospheric CO<sub>2</sub> at levels from 3 million years ago
vendredi 10 mai 2013 à 14:00The last time Earth had as much atmospheric CO2 as it has now was 3 million years ago, and it was 8C hotter than now.
Sea level was 40 meters higher (120 feet). So if we don't get this CO2 out of the air, we're sunk!
