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.

Let's go! Solar punk timeline please!

...in generation of electricity. Most energy usage in the EU isn't electric and non-electric energy usage is almost exclusively fossil fuels.

Even so, baby steps are still steps. Just because not everything has been replaced doesn't mean it won't get replaced in the (far) future.

Electricity is replacing fossil cars with electric ones and heating (heat pumps). As it has replaced the use of candles.

Yes, although very slowly.

A mere 15% of new EU sold cars are BEVs, the average age of the fleet is 12 years, and electric heavy vehicles are still almost non-existent.

Meanwhile, central & southern Europe are still running on Fossil Gas despite heatpumps being around for ~50 years by now. The key issue is that the price of electricity has been far too high, and getting even higher in recent years.
