Classic stuff. First global warming was a myth. Now it's real, but we aren't causing it and even if we were causing it there isn't anything we can do about it.

Nice try, but mostly wrong. On a ton for ton basis, yes, the CO2 equivalent for methane is 21 (one ton of methane is worth 21 tons CO2). However, the amount of methane generated via livestock is negligible to the amount of CO2 generated just from vehicle exhaust, let alone total fossil fuel usage.

Look at the 2004 National Emissions Inventory. Fossile fuel burning accounts for more than 5600 Tg (million metric tons) CO2 equivalent. All methane sources together account for 557 Tg with landfills and natural gas systems making up about half of that alone. Continuously bringing up methane from cows is either ignorant or trolling. Since I know you are an intelligent person, I'm going with trolling.

Don't take this personally, but you need to read up on what a theory is. If you are implying that when there is enough evidence then they will become laws and not theories then you are wrong.

For the record, I think the lawsuit is silly and shortsighted. If CA really wanted to do something beneficial rather than attention-whoring, they would institute stricter fuel efficiency requirements. Start with attainable baseline llevels for each vehicle class and raise those levels annually. Existing vehicles would of course be grandfathered in but if a new vehicle cannot meet the current efficiency standards it cannot be sold in CA.
