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.

Swapable batteries will never happen in cars. (might for semi trucks or tractors). The individual cells in a battery are small and car designers want to cram as many in as they can where they fit. Thus the incentive is to make each battery an odd shape around the other things in the car.

Yeah, but standardized swappable batteries would be great for consumers, and ensure a used car market could exist.

A 15 year old car might not be supported by a manufacturer, but if it was a standard for those years there'd be a big enough demand even if it's a third party that fills the void.

We need to think long term, and cars being junk after a decade ain't a good long term strategy.

The cells should be individual 18650 which are standard and easy for a tech with the right training to replace. No need for a swap able battery, just repairable is all we need.
