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 live in a shitty house from the 50s in Poland, poorly insulated AND I walk around the house on a t-shirt if I want... the problem is the energy I have to spend. Heat-pumps are not a miracle if your house is poorly insulated.

I've been remodeling my house one room at a time, I'm taking insulation very seriously and putting as much as I can. The rooms that I've remodeled are so hot during winter while rest of house is freezing, quite annoying for my HVAC system actually, but interesting how much money is just flying away through the walls

If I may suggest you focus on air tightness as well. Insulation isn't very effective with air flowing through it. If you've worn a fleece jacket on a windy day you'll know what I mean.

That, and vapour penetration through a poorly sealed envelope can lead to moisture issues.
