Climate - truthful information about climate, related activism and politics.

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.

I don't think that will be an issue. In the US, most batteries are warrantied for ten years/100,000 miles, which means they confidently go longer. I believe most batteries are also cell based, so failure isn't 100%. Probably just a shorter battery life. Lots of people will be fine driving with a shorter range.

There are also used batteries and battery recycling. Plus in ten years there will be new technology, efficiencies in production, etc.

These vehicles will probably follow the same life cycle that most do. Being passed down from new owners to used, etc.

This is in fact the only coherent argument for why US electric vehicles all have such absurdly huge ranges - so that they still have decent ranges even when old.

EV battery recycling is already a thing. Hopefully the relevant authorities start putting out some standards for battery packs to keep them at least somewhat recyclable though, since that's getting to be a problem given that every single auto manufacturer seems to be building custom packs for every car.
