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.

The attacks come from an emotional, not logical place. Maybe someone can help me understand why there is such a strong reaction to even mentioning the word "vegan" among some folk.

I think there is this tension whenever a moral norm is changing in society. Vegans are telling people something is worthy of dignity and respect that currently isn’t being granted that status. The cohort of vegans is growing. People don’t like to be made out to be unethical for something they never even considered could be unethical.

this process is how ethics comes to be—a new ideal slowly permeates society as more people adopt it and eventually we decide “cannibalism is unethical” (or whatever) is a general rule and teach that to our children who hopefully perpetuate the rules that ring true for them.

I don’t know for sure, either, but if I had to guess then it has something to do with A. being vegan can be a marker of other progressive beliefs, or perhaps more significantly, B. the consumption of meat is glorified as a traditionally masculine trait
