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’s not easy insulating old houses, getting into all the neuks and crannies. The people who know those best are the inhabitants, so there should be more incentives for DIY solutions. Also, such houses were built to be heated one room at a time, not for 'modern comfort' with thermostats and open doors, so expectations could adapt - really cold-blasts in western europe only last a couple of weeks. Alternatively 'heritage' expectations have to give, to cover exterior walls. Traveling further east in europe, you rarely see bare brick walls, they are always painted (with insulation below).
