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.

It was never going to happen. To make actual change people have to be willing to sacrifice. And no one is, the richest of us least of all.

A heat pump is not a sacrifice. An electric car is not a sacrifice, even well-working public transit is not a sacrifice. Wind/solar are not sacrifices. Vegan diets become less of a sacrifice by the day. All of that would get the bottom 80% of the population a large part of the way, right now. The only people that would really have to sacrifice are those who are the richest.

From my POV a huge one is that we can't all own a several-ton personal vehicle. This is something people will not give up on in the near future, not even in my country which is eminently walkable, bikeable and with fairly good public transport.
