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.

Real-world CO2 emissions of cars are 20% higher than indicated. For plug-in hybrids they are 350% higher. (climate.ec.europa.eu)

It's not a typo: plug-in hybrids are used, in real word cases, with ICE much more than anticipated.

In the EU, fuel consumption monitoring devices are required on new cars. They studied over 10% of all cars sold in 2021 and turns out they use way more fuel, and generate way more CO2, than anybody thought.

The gap means that CO2 emissions reduction objectives from transport will be more difficult to reach.

Thruth is, we need less cars, not "better" cars.

No? The main reason I would consider taking a car over bike or bus is if I am going long travel with family or have multiple passengers. Either way if a car can't be of use when I need it the most then it's pointless to me. Might change if the tech and infra improves here but for another few years it is not even an option for me.
