Give that to me as a percentage of the overall atmosphere. Here I'll help
http://en.wikipedia.org/wiki/Earth%27s_atmosphere

Now lets compare that to a planet where they really do have a greenhouse effect

My point is 1.35 x nothing is still nothing. If you go out into the desert
you can claim that there are 380ppm of water and you can increase that by
100% and there is no change, it's still a desert.
