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.

If you got an Audi E-Tron or Porsche Taycan when they came out, you got OBLITERATED on depreciation.

Um, shouldn't you be talking about Priuses and cars accessible to normal people? Way to scapegoat!

A Prius is not an EV, it's a hybrid.

The E-Tron, EQC and Taycan were among the first non-Tesla EVs widely available in Europe that weren't utter shit like the Leaf and I-Miev. The original Ioniq (without a number) was also quite shit, it barely had a battery. There are plugin hybrids with similar size batteries out there. The Kona EV and its Niro sister were about the only cheap EVs that didn't absolutely suck, but these were also more expensive than their ICE counterparts and I have a hard time figuring out the actual depreciation because there are very few used ones for sale here outside of super low mileage ones at dealers. Despite the lower price, they seem to have sold much worse here than the luxury EVs. Basically 6-8 years ago if you were buying an EV, you probably weren't looking for the cheapest possible option because if you were, you would've just stayed with an ICE vehicle and probably buying used anyway.

If we're talking about total cost of ownership for EVs over their lifetimes and saying that EVs were cheaper to run than ICE vehicles for "a long time" already, those are the cars we have data on. Once we get into the 2020s, there are lower priced options that don't suck, and their depreciation curve isn't as bad. And honestly, the Ioniq 5 is probably a better car to own than the e-tron or i-pace. Which is why I'm saying that any of the early options that didn't suck, depreciated so much it was hard to justify them economically compared to ICE vehicles.

Hmm, fair. And oops, I forgot since I basically drive my Prime like an EV, haha (almost exclusively short distances; filled up twice this year).

I was thinking of the Ioniq next... But I do have high hopes for the Hyundai Casper... Haven't heard much about it, though. Anyway, I feel like a lot of the price depreciation is due to the industry's age. Their insurance also costs more because parts are rarer, but as they proliferate, that should even out.
