Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Don't forget the cross subsidies from co-products.

If ground beef (aka beef mince in the UK where this story is running) is the cheapest trimmings that remain after all of the expensive cuts have been processed, it's entirely possible that the low price for this byproduct is partially subsidized by the high prices for the premium product (expensive steaks, moderate expense whole cuts). Plus things like hides for leather.

For now, the plant-based competition is aiming at the types of meat that are easier to mimic or replace with plant-based foods. And unfortunately, those happen to be the cheaper types of meat. If we get to the point where there is significant plant-based competition to filet mignon, that product will have a lot more room to work with in being price competitive.

Pricing inputs get complicated, and government subsidies are only a piece of the picture.

what you said doesnt negate what i've said. im posing that without the heavy subsidies, we would see a more accurate consumer pricing, that remains true. of course there are other factors involved, that goes without saying.

Not every reply to a comment is intended to do that.

well forgive me, but it seemed like there was a tone of correction happening, my bad.
