Had never read such a thing.

Beyond it's shortcomings, it doesn't really solve anything.

The land growing grass and corn to feed livestock isn't suddenly going to be abandoned, or even repurposed, and it's that biomass that's the ultimate source of those emissions.

If nothing else, there'll be that many more fields of corn destined for the ethanol refinery.

It's cow burps. That's it.

Land-use in the U.S. for cattle has actually been decreasing for decades. It's only increasing in Brazil because of new access to Asian and European markets.

No, it's decomposing grass, expelled as cow burps.

That grass decomposes whether it's eaten by a cow or not.

And grazing land use has been decreasing, but not land use for producing feed.

That isn't contested. Decomposing grass won't yield those methane emissions, at the very least insofar as it won't decompose at the same rate.

That's not the alternate reality though. The land will be put into productive use that's doesn't include leaving it to decompose on it's own, at it's own rate. It's either still harvested as hay and fed to something else, or the they grow something else, like corn, that they intentionally ferment into either other feed or energy products.
