Climate - truthful information about climate, related activism and politics.

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.

Grass-fed beef was supposed to be better for the environment? Before I gave up meat, I just assumed it was better for the cow.

[–] themeatbridge@lemmy.world 38 points 2 days ago (3 children)

I have never heard anyone claim grass fed beef is more environmentally conscious.

[–] blakenong 14 points 2 days ago (1 children)

I just heard it was better tasting, regardless of the environment or the cow… who I assume it treated poorly regardless.

[–] futatorius@lemm.ee 1 points 2 days ago

It has flavor. Corn-fed beef is bland in comparison.

[–] sexy_peach@feddit.org 11 points 2 days ago (1 children)

It's a very common misconception and lobby talking point.

[–] themeatbridge@lemmy.world 8 points 2 days ago

I can believe that, I just have never heard it before and would have assumed whoever said it was either lying or mistaken. It's not a credible claim.

I would say it puts a lower upper limit on the amount of cattle a certain area can feed, unless the cows don't get extra food. This results then in fewer greenhouse gases being emitted.

[–] themeatbridge@lemmy.world 2 points 2 days ago

Grass fed doesn't necessarily mean grazing. Capitalists gonna capitalize, so factory farms will buy grass grown elsewhere and stuff it into the cattle troughs with candy factory seconds and all the growth hormone they can legally ingest. If farmers clear cut old growth rainforests to grow grass feed because it takes more space to get the same output, then it's very bad for the environment.

[–] faythofdragons@slrpnk.net 2 points 2 days ago

This is the argument I've heard. You get more nutrition from a field if you grow feed crops and less if it's just grazed, so grass-fed yields less cows per acre. It doesn't change the amount of methane per cow.

[–] masterspace@lemmy.ca 8 points 2 days ago (1 children)

While I generally agree, I have seen the argument that grass will grow in thin soil where crops will not, so you can theoretically turn land that's unusable for crops into being usable for producing beef...

But that was more of a land use argument than an environmental one.

[–] socsa@piefed.social 3 points 2 days ago

This is literally the origin of livestock farming. And it isn't just about infertile soil or difficult terrain - it's a simple matter of scale. If you have more land than you can farm, you graze livestock on it. Livestock also acts as a super important calorie sink over the winter when you can't farm.

Then there are places like Iceland, where large scale agriculture is literally impossible, and the only way to produce food domestically is to graze sheep on the small bits of vegetation which can grow in volcanic rock.

I think it's better for the human, it tastes better than beef from cows that have been fed corn husks, bone meal, and cough drops.

[–] RvTV95XBeo@sh.itjust.works 4 points 2 days ago

Lots of people think naturally grazing cattle is somehow less resource intensive than the alternative.

It's the "yeah, factory farms are bad, but I get all my beef from my made up neighbor who runs a sustainable farm" crowd.

[–] MDCCCLV@lemmy.ca 3 points 2 days ago

It's better than burning down the Amazon to grow food for the cow, but then that only works if you only have as many cows as natural grassland supports.

[–] Boomkop3@reddthat.com 1 points 2 days ago

At a large scale you could stuff a bunch of cows in small boxes and feed them corn. Which is space efficient and government subsidised in the usa. It's probably worse for the environment because of it.

Grass fed means the cows are let out to roam free. What's better about it is that those animals are not forced to be locked in a box their whole lives

This headline reads like a gotcha, but the point of grass fed cows isn’t reducing CO2, it’s having the cow not live in an unsanitary torture chamber and thereby being more ethical and also less risk of spreading diseases and antibiotic resistance.

[–] silence7@slrpnk.net 2 points 2 days ago

It's been part of the marketing, whether or not it was the main point.

[–] gravitas_deficiency@sh.itjust.works 3 points 2 days ago* (last edited 2 days ago)

So just to be clear, beef being grass fed is more about the flavor and quality of the meat than it is about ecological friendliness. And the livestock having a less shitty life is kind of just an ancillary benefit of that.

[–] Boomkop3@reddthat.com 18 points 2 days ago* (last edited 2 days ago)

Ehm.. that's not the darn point? It's to give cows a better life, rather than locking them in a box with cheap powerfood.

This is a textbook case of disinformation. From the newspaper that is owned by Jeff Bezos to no surprise to anyone

[–] djmikeale@lemm.ee 2 points 2 days ago (1 children)

To me the most interesting part is the following with bold

They found the emissions per kilogram of protein of even the most efficient grass-fed beef operations were 10 to 25 percent higher than those of grain-fed U.S. beef — and many times as high as those of plant and animal alternatives.

[–] silence7@slrpnk.net 1 points 1 day ago

Yeah, shifting to chicken, or better yet, plants, is one of the easiest ways to cut emissions. It's not enough on its own, but it's enough to matter.

[–] Oisteink@feddit.nl 10 points 2 days ago

Never heard it as something more environmentally friendly. But for me taste is better and it’s overall better meat that the non grassfed. It’s less «air» and more meat. Source: me, not a chef or know anything about cows, but i like meat

[–] futatorius@lemm.ee 1 points 2 days ago

It's still leaner and tastes better.

[–] br3d@lemmy.world 4 points 2 days ago

I think people are missing the point a bit here. This work takes away an excuse for eating beef. Thanks to this work, people can no longer kid themselves that eating beef is innocuous because they bought the happy-cow version. Now they should know that eating beef means choosing between more climate emissions or more animal cruelty, but there's no guilt-free version.
