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.

Yeah, I had already done so for about a decade already and then they bought a brand with some of my favorite vegan products (mostly meat alternatives) some years ago and then it got real fucking personal. It's stuff I grew up with, wasn't fully vegan myself till 7 years ago but have always had vegetarians and vegans around me my whole life and they were some of the earliest really good meat alternatives here. It was already personal because of who they are and has done, is doing and will continue to do, but now it was a more direct change in my life and a fist in my gut. I still miss those products, but will never ever buy or eat them. The brand is called "Hälsans Kök" (Swedish) which translates to "kitchen of health" which is now ironic as fuck, and I just don't understand how they managed to buy it. Fuck the original owners too for selling out.
