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.

Some farms that feed cows in yards already use food additives that help reduce methane production in a cow’s stomach, but they have downsides, such as variable efficacy and the need to be constantly supplied, which is difficult if the animals are free to roam.

A vaccine could be an alternative, and the Pirbright Institute in the UK, a virology lab focusing on livestock, is leading a three-year study to develop one. “The appeal of a vaccine as part of the solution is that it’s a very well adopted, common practice, with infrastructure able to do this already, and people know about the benefits of vaccination for animal health generally,” says John Hammond, director of research at The Pirbright Institute.

vaccines, named for the French word for cow due to the first one invented being for cowpox, have truly come full circle. moo

It's way simpler to just farm something other than cows. Plants, maybe.

Changing their diet works just as well and is probably cheaper.

If you want to vax your livestock, how about giving them a bird flu vaccine instead?

The methane released from cows is only one facet of their negative environmental impact associated with upscaled meat production.

Yeah this is just the meat/dairy industry version of what the electric car is to the car industry

It's insane how beef consumption never gets mentioned for global warming. Somehow straws got more attention than factory farmed beef. The straw problem solution was worse than the symptom. This planet is cooked literally and figuratively.

The straw thing was a manufactured distraction.

People are just big emotional children, and if you suggest they shouldn't eat so many burgers they don't evaluate the facts, pros, and cons. They have a feeling and then blame you. And probably go on about how vegans suck.

I'm not a vegan but I try to eat less meat because come on.

"Lalalala! I can't hear you with my hands over my ears and me talking about straws so loudly!"

Cognitive dissonance is a helluva drug.

I recently had an exchange where the other person was trying to argue that meat consumption had nothing to do with production because production occures before consumption. I was talking to them for like a day but uh yeah. at that point I blocked them.

To an extent they're right but probably not in the way they intended to be. Government subsidies help ensure that animal ag can be profitable and incentivized regardless of consumption levels, and the ever-expanding amounts of land required for most animal ag and it's support infrastructure (eg feedstock production, a byproduct of industrial soy oil) literal fuel and are fueled by imperial expansion in a cyclic self-reinforcing fashion. If people stopped eating beef today without also protesting it's existence you'd probably see the animal ag industry continue to run on it's own fumes for years.

subsidies are one thing but I don't think its enough if it has to be thrown striaght into the trash.
