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.

Where do you get “20 years?” And what does that matter? I mean, yeah, I do. Some prime mid-2000s Altimas with destroyed bumpers roll around my neighborhood.

The average lifespan of a car is 10 years. I buy 5-year-old cars and keep them for another five. If it’s undriveable, a scrap yard can part it out and keep similar cars on the road longer.

I notice you conveniently ignored the points I made about things that would actually be good for the environment. Your EV isn’t reducing all the other harmful effects of driving aside from carbon dioxide, and even that’s not a clean win.

10 years sounds shockingly short. My impression is that the average car lasts about 20 years. Lots of older cars still on the road.

Ok... so when you drive every single vehicle into the dirt now what? Stop being dense.

Also i didnt ignore your point. You just expanded on my point. So thanks i guess.

I already said “now what.”

One of us dense — that we can agree on.

You litterally said the "average lifespan of car" is 10 years. Which means wait for it... people replacing them with new vehicles. You and I in agreement that the true solution is reducing personal vehicles dependency. But you trying to discourage EV adoption isnt helping anyone.

Where did I say people shouldn’t buy an EV? I said keeping your current car, given it’s driveable, is more environmentally friendly than buying a new car.

Are you able to win an argument against anyone but a strawman?

[–] piccolo@sh.itjust.works 1 points 11 hours ago

Speaking of strawmans... Point me at the person that ever said replace functional vehicles with new EVs?
