Here is an example of science on the other side of the discussion. It represents for me though an example of a place where interpretation means everything. There is a chart on this page showing the IR absorption in the atmosphere. It shows it for 100ppm and for 1000ppm.
If I read correctly, he is saying "See at 1000 ppm, the band of absorption is wider".
I look at it an say, "See, at a 10X increase in concentration, you get a slightly larger absorption window. It ain't even 10% wider" (Excuse my eyeballs, I didn't get the ruler out to measure.)
