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.

The enormously high price of e-fuels means that people are unlikely to choose them for any kind of application where electrification is possible. This means that marketing an e-fuel-capable petrol car is basically an effort to prolong the use of fossil fuels, rather than any kind of serious decarbonization effort.

That was the deal. It basicly allows Porsche and Mercedes to buitl ultra luxury e-fuel cars with a combustion engine. Kind of like mechanical watches, totaly stupid from a technical perspective, but kind of cool for some people. They should be set up sp, they can only run on e-fuel and not petrol.

Hmmm... sorry but mechanical watches are awesome.
