Snowball Earth Wikipedia

The carbon dioxide levels necessary to thaw Earth have been estimated as being 350 times what they are today, about 13% of the atmosphere. Since the Earth was almost completely covered with ice, carbon dioxide could not be withdrawn from the atmosphere by release of alkaline metal ions weathering out of siliceous rocks.

Dr. Vincent Gray on historical carbon dioxide levels ...

Jun 04, 2013· CARBON DIOXIDE. There are two gases in the earth’s atmosphere without which living organisms could not exist. Oxygen is the most abundant, 21% by volume, but without carbon dioxide, which is currently only about percent (400ppm) by volume, both the oxygen itself, and most living organisms on earth could not exist at all.

Climate and CO2 in the Atmosphere

Since of the Earth''s atmosphere is outofbalance with the conditions expected from simple chemical equilibrium, it is very hard to say what precisely sets the level of the carbon dioxide content in the air throughout geologic time. While scientists are fairly certain that a 100 million years ago carbon dioxide values were many times higher than now, the exact value is in doubt.
