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:

A sustainable diet leaves room for two chicken breasts a week, study says (phys.org)

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.

How does that work? Do you never eat meat when you go out?

There aren't a ton of places in the world with a good supply of vegetarian/vegan food AND enough of an ag industry you can go around petting your meat.

A majority of restaurants where I live offer at least one vegetarian option on their menu, and commonly also a vegan option (they might be the same)

Going out I have lots of vegan options so that isn't an issue generally. And am not rigid in my principles, being a bit moderate makes me less of an obnoxious cunt. Easier to cook for, take along on outings etc.

If I hold hard on any principle it is that to not let perfect stand in the way of good. Being able to do 90% ethical consumption I find to be much better than failing to be 100% pure.

So when you buy meat you try to buy local. but when you are not being an obnoxious cunt outside you just eat any old meat?
