They flatuate and combine to release an unbelievable amount of methane which is a much more effective greenhouse gas than co2. |
You need to learn about perturbation theory, I think.
The climate was built (to use a slightly inappropriate term) to handle the methane put out by animals. It wasn't built for extra CO2 or methane or other gases put out by human civilisation.
And you say that methane isn't a pollutant because it occurs naturally? So how do you explain, for instance, OIL? When there's an oil spill, it's a case of massive pollution. But oil occurs naturally on the earth. Carbon dioxide is completely natural, but elevated levels of CO2 cause the oceans to become more acidic, polluting the oceans in a nasty way.
