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.

Vegans love to conflate all meat into one big group because their goal is to make veganism look good in comparison.

In reality, beef is the main problem.

It would be a lot more environmentally effective to convince people to reduce beef consumption and replace it with chicken/pork instead, but vegans aren't interested in that because for them it's not really about the climate - it's about reducing animal suffering and death.

This duplicity muddies the waters and makes getting real actual change that would benefit the climate harder to achieve and less likely to happen.

I feel like it's so unfair that there's so many people in the world we need to stop eating our favorite foods. How about reduce the human population instead? Such that we could all sustain an enjoyable existence where we don't have to worry about what we eat...
