Methane (cow farts, if you will) is a much greater contribution to greenhouse gasses.
However, the contribution of greenhouse gasses to global climate change is not yet determined.
Measurements of global climate over the past two centuries are inaccurate.
Global climate change models cannot be validated; even when random data is input for past climates, they predict warming.
Ice caps are receeding on Mars...and they don't have cows or cars.
So, those who predict catastrophic warming in the future have not proven their case.

Neither. It's the natural climate cycle.
