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.

Rich asshole: see, they keep eating beef. Why should I change.

Reality: we all do

More like…

NOT rich asshole: I don’t even own a home. I had a steak last month I think.

RICH asshole: I fly across the country twice a day in a private gulfstream and eat whatever I want.

OBLIVIOUS HIPPIES: clearly middle class people eating beef is the issue. Why won’t you change?

Both are the problem. An activity that is less harmful but more people do can add up to more than a more harmful activity that very few people do.

No pathway where we avoid the worst of what's coming doesn't involve this sort of change for most people.

Certainly not absolving everyone of their own personal responsibility to the problem and generally all avenues should be encouraged.

But reality is convincing the entire population to sacrifice what they eat while ignoring 75% of the problem isnt helping and won’t win hearts and minds.

As I mentioned in other comment: what improves are world more RIGHT NOW? Trying to convince thousands to altruistically sacrifice what they fucking eat? Or better regulating the emissions of a single source that would outweigh them all?

Half of an America votes republican… whining about their dinner plate is useless compared to just regulating the emissions of a type of transportation used by a few billionaires. Why do

I never see articles about reducing the emissions of farms/ranches. Apparently there is nothing they can do. It’s clearly all my fault for eating…

Different actions aren't separable in that way. Adopting one "green" behaviour will shift peoples attitudes to others and make wide top-level change easier to implement. "What We Think About When We Try Not To Think About Global Warming" has a good discussion of this and there may be some more recent resources. This is especially true when both (all) changes are necessary. I can't easily stop private jets but I can quite easily not choose the worst option for my diet (and also other things like avoiding discretionary flights). Seems really clear cut to me that we should be doing the bare minimum in our personal lives whilst we organise to make the worst offenders accountable.

I agree with you that regulation (of meat production) is vital to all this as well but that will mean costs going up which needs to have enough people on board and aware of the harms to facilitate. We need enough change in attitudes to facilitate the necessary changes in regulation and law (whilst also tackling the inequality, the powerful and structural economic system that promotes harmful behaviours for their benefit). .

I don’t entirely disagree with your point, but that’s a severe misrepresentation of how much beef the average person eats
