Methane is only about 1.7 parts per million in the atmosphere. The radiative forcing is about 0.5 W/m2. That’s about a quarter of the forcing of CO2. Together these effects might warm the planet an average of 1.25 C if we ignore all positive and negative feedback. The overwhelming evidence of the geological record is that the system as a whole asserts negative feed back and resists forcing. The evidence of computer models that assume a strong positive feedback have become a way to get research funded from government sources dominated by the alarmist movement. This crap has got to stop. Its a corruption of science, a waste of tax payer money, a danger to good economic policy, a ideological wedge for Americans, and robs money and effort from solving real environmental problems.
How dare you refer to actual science.
By the way, look up the W/m2 of water vapor (not clouds) THE most prevalent greenhouse gas ...
