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.

Given what we know about the limits of soil seqeustration this is basically a PR exercise by the meat industry to keep the methane flowing into the atmosphere.

What the hell is COP at this point? It's just a corporate champagne lunch where billionaires compete to see who can be the most horrific pollutors.

"Hey guys! Check this out this severed baby head on a stick! What does it have to do with climate change? Who gives a fuck?! Let's light it on fire!"

Raising animals for meat isn't inherently an awful thing for the environment. There is land that is useful for grazing but unsuitable for growing crops. Turning inedible grasses into meat is very useful but industrial scale grain fed and fattened meat production clearly is a problem.

That's a huge part of it. The second problem is that cattle produce a lot of methane as part of their digestive process. Other species produce a lot less.

We would need alot less land, if we only used it for plants to feed humans, instead of using it to produce meat. Land that is now used for grazing could be rewildered and contribute to countering the massive loss in biodiversity. It is one of the greatest errors of the system we live in, that everything is seen trough the lens of generating short term profits.

Eating meat isn't inherently bad or ecologically damaging. Humans are animals and part of Earth and as such have as much right to eat animals as a lion.

The problem is that there are 8 billion people on Earth and to feed that many people, our food production must be industrialized. Industrializing food from animals means treating them (and the environment) like objects.

Greedy, power hungry psychopaths and their need to hoard resources and power are the root of the problem. Their favorite tools of markets and capitalism are what drive unsustainable population growth.

The solutions to these types of problems are not to make everyone vegan or force us all to live super efficient zero waste lives in cities packed like sardines. The solutions involve moving beyond capitalism and degrowth.

Edit - I want to clarify I'm not defending these plans, just stating a position related to the post.

Next on deck: cars propose sheltering the earth from the sun by covering it with one big ass parking lot.
