" It isn't scientific." CO2 takes in infrared radiation from the sun, and the infrared radiating back up from the earth-surface(after being warmed by the sun) and changes its frequency and reflects it back in a random direction. this in turn prevents some of the suns energy from leaving the earths atmosphere, preventing the earth from cooling itself, specially at night.because more energy stays on the earth surface instead of being reflected back out into space more energy goes into the atmosphere raising its temperature.this, in a very small nutshell is how all greenhouse gasses work, including water vapor and methane.CO2 is such a problem because the mechanisms to take CO2 out of the atmosphere work very slowly, and the CO2 we pump in(i'm assuming your at least educated enough not to argue against this fact) could take millenia to disappear out of circulation. watervapor forms clouds and start raining when there is too much or its to hot, and methane breaks down into CO2 and water inside of a decade under influence of sunlight.now unless you can explain to me how this is incorrect and CO2 doesn't cause a warming effect, I'm going to side with all the scientists that know what they are talking about and not with the few paid for by the cool, oil and gas industries.excuse my spelling mistakes if any, im dyslectic and non-english. im telling you this because some people dismiss a valid argument out of hand because it contains a spelling mistake, as silly as that sounds
