Human CO2 is a tiny percentage of CO2 emissions. Sks wrong again.

Another debunking of one of UNSkeptical UNScience -SS's- so-called "Myths." This time debunking their #33

"Human CO2 is a tiny % of CO2 emissions" The natural cycle adds and removes CO2 to keep a balance; humans add extra CO2 without removing any.

Debunking of all 178 will be found on this page - SS "Myths" debunked.

SS's Explanation:

Before the industrial revolution, the CO2 content in the air remained quite steady for thousands of years. Natural CO2 is not static, however. It is generated by natural processes, and absorbed by others.

Did SS check? Or just create their own history?
