I don't get it. Climate change critics try to find one flaw in some straw man argument and then denounce the whole field as a lie. CO2 isn't the only thing that causes warming and no, scientists are not stupid enough to not account for these things. I mean this statement is trivial to disprove because methane and tons of other things also act as greenhouse gases or amplify heating. It doesn't change the threat caused by higher temperatures. 4°C are 4°C and we can bet on going way beyond that tiny puny number if no ones gives a damn.
It's one flaw of many. First, nobody really trusts the temperature data. Second, the earth was much hotter before. Third, there was an ice age, now there isn't, planet was already warming. Fourth, water vapor is recognized as the most powerful greenhouse gas. Fifth, we don't believe solar energy is being adequately accounted for.
We have a what we consider a lot of holes, big import holes, in the theory. These issues are immediately dismissed. The fact that people can say with a straight face that water vapor increases global warming, yet is not the primary cause, even though it's the strongest greenhouse gas, is beyond believe. It defies comprehension, I will never, ever take the CO2 theory serious, and I'll be here encouraging others to think for themselves as well.
