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.

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.

Well, beef is already so damn expensive that I can't remember the last time we bought it.

Meat-wise It's just been a steady cycle of chicken, turkey, and pork at our house

I had no idea we were so environmentally avant-garde

Good on you!

When my wife and I started being conscious about our food intake, it wasn't too bad to give up red meat, and shrink meat portions / add veggies.

It took us months of learning / trying new recipes to actually get to the point where we were consistently eating fewer than 14 meat-centric meals a week (lunch/dinner). Once we got comfortable cooking plant based dishes though, we had built up so much momentum that we went from 1 or 2 plant based meals a week to 100% in just a few weeks.

It takes a long time to build up that comfort level, but at some point a switch just flips and the new "normal" is just as easy as what you were used to.

You're not avantgarde. Veganism is a thing.
