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.

Yep, we're pretty fucked. Humanity had a good run, I guess. The plot got really stupid here towards the end though.

Oh, when can we expect the cooler weather?

There's huge uncertainty on the timing of when it gets bad enough to be meaningful in Europe. Anywhere from 25 to 100 years is plausible, and whether it happens at all depends on human decisions about how much to extract and burn.

Probably just a similar amount ti what we're doing now.

At least the weather is very cool and stable in underground prepper bunkers.

Atlantic Ocean should switch internet browsers and even their OS ..... and use a VPN ... to avoid fingerprinting

There, solved the problem.
