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.

Doesn't matter.

The initial suggestion was of a ban in 2030 from 10 countries that already had plans of banning fossil fuels from 2030 or sooner.

The 2035 deadline was a compromise to allow the car manufacturers to get up to speed. If they try to prolong that, some countries might just go back to their local legislation and ban the cars even sooner.

EU can potentially claim that such bans are against the free trade in EU and force it through, but they can never actually force anyone to buy the cars.

The decision of switching to EVs is entirely up to the local drivers, regardless of what arbitrary deadline the manufacturers try to lobby through EU.

Even in France and Germany, who produce fossil fuel cars, there are cities with environmental zones banning fossil fuel cars. Just as it today doesn't make any sense for people near Berlin to buy a diesel car that they can't drive in Berlin, every potential car buyer in all of EU are going to have to consider if they can even use or resell a fossil fuel car in their local area within the expected lifetime of a car.
