Question

This figure shows the carbon dioxide levels in the Earth's atmosphere over the last 400,000 years. Use it to answer the flowing questions. After an ice age, how quickly do the carbon dioxide levels increase? Remember the connection between carbon dioxide and global temperature. How many ice age cycles have there been in the last 400k? It may be easier to find the "spike" in increasing carbon dioxide levels after an ice age. Are the current carbon dioxide levels in the atmosphere the highest the Earth has seen in the last 400,000 years?

Explanation / Answer

1.) After an ice age the carbon dioxide concentration level increases in 50000 years to about 250-300 ppmv.

2.) There are about 4 ice age cycles in last 400000 years.

3.) Yes the carbon dioxide concentration today is about 440ppmv which is highest value in earth from the last 400000 years.
