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.

It should certainly be the first step. I've started like this, continuously less meat, your gut-biome slowly adjusts. I'm still not vegan/vegetarian but basically eat no meat anymore (mostly leftovers of others). A good part of it is that I just don't really like meat anymore (tastes kind of rotten?).

I recommend going this route, as I think it's easier to get into a vegan diet.

That said I think we (as a global society) should strive towards eating only vegan long-term. We got the food science and it just feels wrong (moral, inefficiency, health) and isn't sustainable.
