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.

About 15-20 years ago, a friend of mine who teaches communication at a university told me of a study that I think of every time I'm in a store and see vague sustainability messaging on a product. The study had two types of milk containers, each with the same milk from the same producer, but one had a standard label and cap, while the other had green-coloured labelling and a meaningless phrase along the lines of "for a better tomorrow". The milk in the green, meaningless labels outsold the other one, even without making any actual claims. I think years of greenwashing BS have made people not trust claims of sustainability or eco-friendliness.

Another issue is hyperbolic discounting. Even if a more sustainable option saves money of the long run, people are generally bad at factoring in future savings.
