Talking in terms of "carbon" is misleading. Methane is much more potent than CO2. I don't know why you think methane is broken down at the same rate as it is added.

- Cattle release methane

- Forests are burnt to make room for crops/grazing

- Fertilizer for crops for cattle produces nitrous oxide

I do not claim this adds up to 60%, but to suggest it is zero is incorrect.

Methane is broken down with a few years delay, but still the same amount is breaking down as is produced. Think of a long pipe which takes a few years to travel through and it's fed at a constant rate. Total methane in the atmosphere stays constant.

But that still means you have a couple of years with a higher concentration of methane, and given the higher impact this is obviously very relevant, no?
