Carbonophobia is a lethal form of retardation. All life is carbon based.

Total volume of CO2 in the atmosphere is only .03%.

Man made contributions to that are 3.225% of that .03%.

We need more carbon!

Man made contributions to that are 3.225% of that .03%.

Manmade CO2 has raised CO2 from under 0.03% to over 0.04% Manmade CO2 adds another 2-3 millionths to that each year. Almost all current observed rise in CO2 is man made. Some 1/100th could still be natural from natural warming over the last few centuries.

The important thing to remember is that the earth was recently in CO2 starvation with the lowest CO2 in earth's history. That threatened all life on the planet. That threat is over thanks to manmade CO2.
