A significant amount of methane escapes the system in leaks
and gets into the atmosphere without being burnt. In the US,
about 1.4%. Other countries do much worse, and a recent satellite
has started mapping the problem:

Methane, molecule for molecule, is a far more potent greenhouse

So, I'd like to see some actual numbers to support of debunk this
claim, not a simple declaration.

 I understand that methane in the sky is slowly
converted to CO2.

Yes, and far faster then CO2 gets recycled. But it's also a far
more portent as a greenhouse gas, pound for pound, as C02. Numbers
matter, and figuring out the relative contribution of each to
warming \caused is a non-trivial calculation.
