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.

Where I live there are little processed vegan options, they are hard to come by/identify, and there are no vegan sections but I'm glad that they are here at all tbh given the state of things. As for prices just like with everything you judge things on a per product basis. If there's something that costs more than I'm willing to pay I just skip it as I'm not forced to buy certain types of products which are generally not healthy anyway. Not that I disagree about pricing being shitty but you just work with what you have since cruelty is so deeply ingrained in our society it inherently requires effort to minimise it. Just like with privacy for example where you actively need to fight for it. It's just something you do. Once my current phone is on death bed I will be buying fairphone which is expensive or a similar product out of the same principle.
