The meat and dairy industry is not 'climate neutral', despite some eye-catching claims

Getting into the dirty dealings of meat industry apologetics:
context:
<💬>
The term “climate neutral” was first coined by policy makers to refer to net-zero emissions of greenhouse gases. These gases were measured using a long-established scale that represents their warming effect over a 100-year period, expressed in CO₂ equivalents – this is the so-called “global warming potential” or GWP100 and it was used in the preparation of the Paris agreement.
But GWP100 is still imperfect because while most methane is in the atmosphere for only a couple of decades, carbon dioxide can linger for centuries. That’s why in 2018 some academics introduced a new metric called GWP* to better represent the warming impact over time.

meat industry science accounting shenanigans:
<💬>
But the reports we examine have used GWP* to subtly shift the meaning of the term climate neutral from net-zero emissions to net-zero additional warming, where “additional” refers to warming on top of that already caused by the livestock sector, not warming compared to if the sector stopped entirely. This means a historically high emitter such as the beef industry can get off easily.
</💬>
The analogy I would make is slapping someone (or some other form of violence that doesn't leave a clear mark). They're trying to claim that they're not attacking the atmosphere because slap damage doesn't last long... while they continue the slapping frenzy.
<💬>
Using GWP*, a livestock sector with high but declining methane emissions can claim to be climate neutral since it adds less additional methane to the atmosphere – and therefore less additional warming – each year. This is referred to in some of these studies as a “cooling effect”, which is misleading since it’s not cooling the atmosphere, only warming it slightly less. These studies also fail to make clear that, like methane itself, this “cooling” effect of methane reductions is temporary. And the level at which they stabilise will likely still be high enough to cause significant warming.
</💬>
So if you see such papers, remember:
<💬>
GWP* certainly has merit when applied at the global level. However, even the scientists who developed it agree it shouldn’t be used to assess a particular region or sector such as livestock.
