It's said (by Science™) that we've gone from 300 parts per million of carbon dioxide in the atmosphere in pre-industrial times to 400 ppm today. The implication is that industrialization is the cause of the increase. But is it?
New paper: only 15 ppm (i.e. 15% of the increase) is from fossil fuels. Hey, you don't want to be a Science Denier, do you?
