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.

You're right about buying new cars.

That said, no car is an investment, in terms of it appreciating in value. I'm sure you know that just I've seen some comments along those lines when people talk about electric cars depreciating.

I would never buy any vehicle that's 10-20 years old if I have any other options available. A lot of shelf life used up at that point.

I bought a used 2023 bolt this year with only 5k miles on it. My previous car was a new 2008 Kia and I figured out with inflation I paid about the same for that one as I will for this one.

I've been very happy with it so far.

If you cared anything about your personal privacy, you wouldn’t touch anything made after 2006 (and a surprising number of vehicles after 1996). They all have black boxes that record all of your driving history, and many models squirt that data back up to the corporate mothership to have your personal and private driving behaviour monetized without your consent. Plus, even what stays on your car is encrypted such that you have zero access to it, and your insurance company can trivially gain access to that data to weaponize it against you in case of an insurance claim.

I would never take a post-2006 vehicle even if it was free, except to immediately re-sell it. Modern vehicles make the Stasi’s surveillance system look like rank amateurs.

And yes, I work in the security end of IT.
