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.

only problem with me personally about this, is that i'm stuck with gasoline using car, i dont have money to buy 50k electric car :/

Cars in general are the problem and even if they all went electric they'd be bad. (But cities would be much quieter and they are hella fun to drive.)

If you're able to use a bicycle for some of your trips instead of a car, that's a good change. (And if you're not then you might not even be able to use an EV car if you could afford it. It takes way longer to charge a battery than to fill a gas tank.)

No they wouldn't. Most ICE cars make a "whoosh" sound, because most of their noise comes from air resistance - which EVs also have. And tires, of course.

Cities wouldn't stink as much, though.

We got ours for 30k with 200 miles on it, retails 45k.

Dealerships hate buying these cars used because they think there isn't a market for used ev's, in part because they're so expensive, anyone who wants an ev can afford to buy one new, they think the second hand market isn't there, go in and offer to buy a used one and see what your dealer says, I bet you can get one for half that.

Also there's some electric only second hand dealerships starting to pop up. Maybe one in your area?

I don't know anything about the situation in the US, but you get great second hand EVs for around 12.000€ here in Germany. Combustion is cheaper to buy but gets more expensive over time. It has over 250 moving parts, EVs have like 7.

[–] reksas@sopuli.xyz 1 points 3 weeks ago (1 children)

problem with second hand ev is that if the battery has to be replaced, might as well just buy new car entirely

[–] Teppichbrand@feddit.org 2 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

Nearly all cars I tried had SOH over 90%. The car I bought is from 2021 and has 94,9% battery health. Buy a 25€ OBD2-dongle and read it when you test-drive it. If the owner cared just a little, battery health is not a problem. Don't let fossil disinformation scare you.

[–] reksas@sopuli.xyz 1 points 3 weeks ago (1 children)

what do you mean cared a little? what affects the battery most? I live in finland and at winters it can get -30c here and only place for car i have is outside. I also worry that i myself might wear the battery down really fast due to not being able to store the car properly. I also need to occasionally do long trips and when i visit my mother, i think the closest charging spot is at least 10km away so i might get stuck easily too if i run out of battery.

I really REALLY would prefer ev, i hate having to pay stupid prices for gas, taxes and even maintenance since combustion engine wears down much faster and worse. But the reality for me is that there just isnt enough infrastructure for ev in north finland for me to use ev without having to worry more than with my current car. I guess rich people dont have any problems no matter where they are, considering how many teslas i have seen, but i'm not one of those. + i just switched my car so my funds for it are expended for forseeable future unless i get work, which in finland seems about as easy to do than winning in lottery if you are not right type of person.

[–] Teppichbrand@feddit.org 1 points 3 weeks ago (1 children)

Here's a study about battery health. Bottom line is, charging from 0% to 100% gives you 500 life cycles until it's at 70% health. Charging from 20% to 70% gives you 6.000 life cycles. That's is a huge difference and you should keep that in mind.

I don't know how low temperatures affect battery health. But ask around, aren't EVs super popular in Finland?

[–] reksas@sopuli.xyz 1 points 3 weeks ago

at least cold weather drains battery, not sure how it affects the health in general but i dont think it does it any good. The people who have ev are most likely those who can also afford heated and closed space for their car. At least i have seen many teslas all around so it would make sense if there are even more evs because tesla is only car i can definitely tell is ev.

I wish evs had somekind of "emergency" battery that would charge the main battery if it gets too low so it would protect it from getting too empty.

Buying your cars new doesn't help.

[–] Darcranium@lemmy.world 1 points 3 weeks ago

Get one used... The batteries are good enough now that even used, they are a good investment
