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.

255 grams per week. That's the short answer to how much meat you can eat without harming the planet. And that only applies to poultry and pork.

Beef cannot be eaten in meaningful quantities without exceeding planetary boundaries, according to an article published by a group of DTU researchers in the journal Nature Food. So says Caroline H. Gebara, postdoc at DTU Sustain and lead author of the study."

Our calculations show that even moderate amounts of red meat in one's diet are incompatible with what the planet can regenerate of resources based on the environmental factors we looked at in the study. However, there are many other diets—including ones with meat—that are both healthy and sustainable," she says.

It's funny to think that you need communism for this kind of figure to mean anything.

[–] ohwhatfollyisman@lemmy.world 2 points 1 week ago

did they already publish an article beforehand on how many eggs are sustainable?

or have they solved the age-old riddle?

Dry ass nasty chicken breast. I'd rather some veggies, but it this allows BP to keep pumping oil into the Gulf then I guess it's fine.

I want this paper without the "healthy" part. Tell us the limits of sustainability, then let people choose their own adventure, even if it isn't a good one by whatever arbitrary standard is set by the researchers for what health means to them.

You want... less information? How does having information on health affects not "let" people make their own choices about their health concerns?? Indeed, how can they meaningfully make such decisions without that information?

[–] dream_weasel@sh.itjust.works 4 points 1 week ago* (last edited 1 week ago) (1 children)

No I want more information. I don't want the current consensus of "healthy" between the authors, which may use arbitrary benchmarks, to prune down options that still satisfy a goal of sustainability.

The research team's calculations take into account a number of environmental factors such as CO2 emissions, the consumption of water and land use, as well as the health impact of a particular diet. In total, they have examined more than 100,000 variations of 11 types of diets and calculated their respective environmental and health effects.

One of these things is not like the others and it looks like it is used to prune the set of variations. Is unhealthy like I get scurvy and die? Or is it that it may correlate with high cholesterol? Or is it that you are at risk of foodborne illness for eating under cooked meat/eggs/seafood? "Healthy" could encompass any of those and that's nuts for data management.

Yeah, I agree here, they do supply all the data and methodology (though obviously some of it is paywalled) and I see how the way they presented it is probably the best for the LCD consumer, but I would have liked a decent concise summary of just the sustainability data.

Let's be honest about how unrealistic it is to expect people to voluntarily adhere to this. We need large scale lab meat asap

[–] ThirdConsul@lemmy.ml 3 points 1 week ago* (last edited 1 week ago) (1 children)

Oh god no.

Look at how much we fucked up natural meat with all the hormones and feed. Lab grown meat must be cheaper to make to compete with it, so imagine how atrocious the quality of it will be, from both health and nutrition perspective.

[–] Zoomboingding@lemmy.world 4 points 1 week ago* (last edited 1 week ago) (1 children)

The problem is that people won't give up personal luxuries for some vague 'save the planet' cause. This is simple fact. The only way to satisfy people's desire for meat and the planet's ecological balance is production of artificial meat.

If you don't think it'll have the best texture or nutritional value, then that's fine. Do you think the people getting McDonald's cares about those things?

Do you think the people getting McDonald’s cares about those things?

I'd rather not fed slab to the masses, thank you. Not only for ethical reasons, but also for monetary ones.

I'm all for the French model where they are taught (and given time and money) to consume healthy food. It's the only Western nation where the obesity rate is low AND decreasing.

Meanwhile, carnivore diet retards exist.

Edit: yeah, pointless as always trying to have a discussion with vegans. 😐

Veggie - not "mains", not complex enough

Plant based meats - too complex

IDK, but it sounds like you haven't really tried the full spectrum of offerings from plants. It's not just beyond meat and celery out there - There's a whole spectrum of flavors and if you want more, but not the full punch of a plant based meat, maybe try incorporating more variety into your plate
