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.

This is such a good attitude! I cut all meat out of my diet a long time ago, and when I mention it, people often say something like "I'd love to but I couldn't commit to never having meat again".

You don't have to! It's amazing if you do, but you're still gonna make a sizable impact on the cause you care about if you reduce your intake.

It's odd that people don't have this with other issues, the idea of "reducing purchases of disposable plastic" or "buying fairtrade more" make total sense to people, but food is still often cashed out in these "all or nothing" terms.

100% spot on. I'm so tired of everything needing to be 100% or 0%. a 80% cut has an impact! so does 50%. we all need to do what we can, and not taking an extreme position doesn't make someone a sellout or faker or whatever. every little bit helps

i don't think so. i don't think it matters what you do in the grocery store or in a restaurant.

I think a lot of people have a problem admitting that the consumption of certain things causes harm, which is why they turn it into an all or nothing decision. But I believe in the principle of harm reduction, and not letting perfect be the enemy of ‘better’. Or put in a more positive light, ‘every little bit helps’.
