CO2 Is Earth's Biggest Woe

CO2 Earth Climate

The climate of the earth is more sensitive to increased CO2 than it was previously assumed. 50 million years ago, during the hot climate, nahcolite crystals were formed. 680 parts per million (ppm) may have been the CO2 level during that period.

1,125 ppm is the level of CO2 predicted by previous experiments. The change suggests the impact of the green house effect has been highly underestimated. 400 ppm is the current level of CO2 in the atmosphere. 30 Celsius will be the rise of global temperature if the level of CO2 is doubled.

The only direct measurement of carbon dioxide is from ice cores, which only go back less than 1 million years.
