.0034% of atmospheric change.

I've often pointed out that the rise from 280 ppm of CO2 to 400 ppm of CO2 is almost completely manmade. There is a natural component to the rise from natural warming from the end of the Little Ice Age and high solar in the 20th century. But that would account for about 5ppm or so of that rise.

The real question is whether it matters. It is clear from history that warming, if any, is good. Civilization blossomed 5000 years ago with much warmer temperatures. Any CO2 we add now helps with that and helps deal with CO2 starvation which was one of the greatest planetary threats to life on the planet.

Correlation does not equal causation. CO2 levels were above 7000 in the Cambrian Period. Exactly whose SUVs did that?
