But I learned climate change on my mothers knee and I'm skeptical of it being man made. There's a lot of conflicting information out there so it's hard to make sense of it all, especially since most of the climate models haven't worked out. Is it true that humans only contribute 7% of CO2 in the atmosphere, and that the greenhouse effect of CO2 is very small according to atomic absorption spectroscopy analysis? Also couldn't out-gassing be contributing to the increase of CO2? I get the impression that any kind of research skeptical towards anthropogenic climate changed isn't taken seriously at all by the climatologist community, to the point of ideological fascism.
