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.

No one is telling you what to do, but the studies are undeniable

The studies have studies and experts denying them.. The rebuttals are a gamut of:

  1. pointing out that the "eat less meat" conclusions are fraudulent misrepresentations of the facts
  2. pointing out that only way cutting out meat in most developed countries would be good for the environment is if we also start ecologically re-engineering for a lower natural footprint than our regions ever had, since the livestock footprint nearly resembles that of pre-colonial days (here in the US, methane emission is within 20%)
  3. pointing out that most attacks on meat-eating make the mistake of mathematically treating marginal land as if it could support a forest, when it cannot
  4. And finally, pointing out that improvements in cattle diet shows dramatically more real-world promise than this contrived idea of forcing or coercing all humans to stop eating meat, with far fewer risks and side-effects to availability of balanced nutrition

Even if the oil industries weren’t such a massive environmental disaster, that wouldn’t change the wild levels of inefficiency and waste in animal agriculture

...in some countries like India. Here in the US, the cattle industry is fairly efficient, in a large part because it is highly profitable to be efficient. In my area, cattle is largely locally fed. That local feed will just as largely end up in a bonfire if we decided to wipe out the cattle population, and there would be a large increase in synthetic fertilizers that are themselves terrible for the environment. If we decided to keep the cattle population without eating them, you might be surprised to note that it would be worse for the climate than eating the cattle we have.

As a whole the meat industry is unsustainable

If that were true, it would be dying instead of dramatically improving in both margins, efficiency, and climate footprint in most countries.

whataboutism doesnt change the facts.

No. Whataboutism doesn't change the facts. On that, we can agree.

experts denying them

It's kinda wild to post "it's not that bad... studies" funded by corporate interests in /climate. It's always the same old denial lines served from the same ole' boiler plate. Do you also give BP the same benefit of the doubt too? Are the innovations of" clean coal" going to revive the industry so nothing has to change?

if that were true, it would be dying instead of dramatically improving in both margins, efficiency, and climate footprint in most countries.

The wildly ineffecient ineffecient industry has long been supported by goverment subsides.

If we decided to keep the cattle population without eating them, you might be surprised to note that it would be worse for the climate than eating the cattle we have.

The obvious answer is to stop breeding them. Their numbers are this high because they are treated as a commodity.

As I said to the other guy, accusing the large percent of studies that disagree with you of being false is bad-faith far-right bullshit, and we had enough of that in 2020 with the anti-vaxxers. I have sworn off EVER giving that style of bullshit any more respect than it deserves.

Do you also give BP the same benefit of the doubt too?

I never said "benefit of the doubt". You're the one picking research based on whether you like its results. I'm the one reading the articles and studies on both sides.

Actually, let me use your reference to show my point. Do you know who the BIGGEST opponent of farm subsidies is? FARMERS.

You tell me why, and we'll continue this discussion. Otherwise, you just showed your hand, and it's a 2-7 off-suit high card.

The obvious answer is to stop breeding them

Till when? In my country, the total methane impact from agriculture is only 20% higher than pre-colonial ecostasis. We will reach those numbers in 10 years. Are you saying my country needs to have LOWER methane emissions than it had 500 years ago all so we can support BP continuing to do whatever the fuck they want and still have a global temperature continue to rise? Because if the worst GHG footprint was my home country's agricultural industry, global warming wouldn't be a problem.

Which one of us is giving BP the benefit of the doubt, now? What percent of environmental spending are you really willing to do to reduce GHG emissions <5%?

Studies and experts funded by the livestock industry, yes. Why are the studies and experts always Mitloehner, I swear...
