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.

I think that's a great recommendation. I really admire your admission of not being anywhere near zero waste. Me neither! But it's better to do better than do nothing. The zero waste movement can get quite fanatical, which is a turn off. Especially if it's about shopping for things to be zero waste with.

I don't do everything right, but I do bring my own bags. But it took years, and like any habit, and like you said, it's about feeling. I'd walk into a store, and it would start to feel weird if my hand is empty. If you forget to bring your bag today, bring it tomorrow. The feelings develop over time.

I know because I've switched recently to getting my bread and croissants in a wax-cloth bag (instead of the throwaway papers). It's been about six months, and I get it right ... about half the time.
