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.

I've tried to go vegan I think three times in my life, and vegetarian a few more times than that. I struggle with concrete issues like celiac, but also vague ones like suicidal ideation and digestive issues. And then there's also the simple economic fact that when certain meats are on sale they're actually cheaper per gram of protein than beans.

I don't mean to say that there are those of us who should eat meat and we therefore require a meat industry, just to explain why some of us have trouble. To the contrary, I think my issues have been exacerbated by a world that insists meat is necessary. If being vegan were the standard, I would have a greater variety of options and more affordability, and medical professionals would be both more accepting and more knowledgeable in providing me aid.

e: "Vegan" is actually incorrect here. There are problems with the honey industry, but I don't think beekeeping is inherently unethical, and I don't oppose symbiotic forms of animal exploitation. I don't know what the word for that would be.
