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.

For a great many used EVs, battery charge capacity wears out significantly with mileage compared to wear and tear on many ICE vehicles, to the point that getting a new battery installed might end up costing as much as you paid for the used EV itself

Latest what research I read showed exactly the opposite of what you have stated. But I would love to see your reference.

I may have overstated the prevalence of that particular point, as I did all my research on that half a decade ago, and I'm talking about the used EV models that I saw available in my area for a cost that would be less than roughly $20k.

A whole lot of the models I saw available, I'd go onto EV forums for those specific makes and and models and find stories of people with the same or similar listed mileages as what I was seeing available, and a whole lot of them were saying that their EVs with 100k to 150k miles on them, the battery packs had about 50% less than the listed manufacturer range from that same make and model whilst new.

And when you are in the used EV market, that can mean that if you get a battery pack thats a dud, well the average cost of a battery replacement is roughly half what youre paying for the whole EV, or as much as the whole cost of the EV if you're going for a cheap option.

Avg battery replacement cost is about $8k, but can range all the way up to $22k, which is basically as much as or more than the cost of a used EV itself if you're aiming for an under $20k vehicle.

However, it may be that newer EVs have gotten better on this front in recent years, and thus the newer, but still used, market offering have improved in this regard.

Going by the % of battery capacity degradation stated here:

https://www.howtogeek.com/806181/why-do-electric-car-batteries-degrade/

of roughly 3% a year, which degrades cumulatively...

That means if you are buying say a 10 year old used EV, which started out at 200 mile range capacity...

That EV now has a roughly 148 mile capacity, approximately a 25% overall decrease in range.
