CO2 from cows is an anthropomorphic cause. I won't go into what to do about it...

1) I have read several papers that claim that the sun, or more specifically, the increase in the sun's activity has a lot to do with global warming.
2) No question that the gasses trap heat. The question is how much of the gases are due to human activity and how much is due to natural causes, such as the increase in volcanis activity.
3) How "necessary" are cows?
