Yeah, but isn’t it their farts that matter?
Yes, but, first things first......................
I thought is was the other end as well.
My first thought too. Ever smelled cow breath? Ever smelled cow farts?

It’s called a “dutch oven”.
The party has a plan for that. They will soon capture the cow farts with a but mask, and route the farts right back around to the cows nose for re-breathing. The SEALS already have it for bubble free scuba.
No lie.

Proof that government grants combined with frulent research produce results that stink.
Need some sent to d.c. stat! 😷💩
That is what I thought, methane comes out of a cow’s rear end after the grass is processed via the stomachs and intestines, not from its lungs via its nose.
Now, while it is true that cows do eructate (belch) a certain small amount of methane gas, the far greater amount is expelled by flatus. From the other end.
All assertions to the contrary, neither methane nor carbon dioxide have any measurable effect on either global warming or cooling. This is a modern mythology built into the current humanistic secularism that styles itself as the religion of the “smartest people around”. They claim to have “science” on their side, but few if any have ever actually STUDIED any of the physical sciences, and those that have, probably flunked the courses anyway.
