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.

Actual good plan:

  1. Announce that the 401 will be permanently closed on Dec 31, 2024.
  2. Do NOT add more lanes to the 403 or the 407.
  3. Start construction of both a high speed, limited stop, rail line and a moderate speed, frequent stop rail line, where the 401 used to be on Jan 2, 2025.

I'd vote for it!

Speaking my love language.

Good news. BEVs save the car industry, which is destroying cities, but it really hurts the oil industry, which destroys the world.

Oh, instead of ones that convert petrol to electricity?

[–] MrMakabar@slrpnk.net 8 points 9 months ago (1 children)

Instead of plugin hybrids, which have both a combustion engine for petrol and a relatively large rechargeable battery. Also it does not include hydrogen fuel cell vehicles.

[–] ultra@feddit.ro 5 points 9 months ago (1 children)

I thought just "EV" didn't include hybrids

[–] GenEcon@lemm.ee 4 points 9 months ago* (last edited 9 months ago) (1 children)

BEV: battery-electric

FCEV: fuel-cell electric (hydrogen)

(P)HEV: (plug in) hybrid-electric

All of them are part of the EVs.

Although this is likely to never happen in the States, the fact that a large number of other countries like Canada and most of Europe are making these changes means it'll become impractical to keep a separate line of ICE engines going as demand for electric vehicles grows worldwide.

[–] MrMakabar@slrpnk.net 15 points 9 months ago

This is happening in some of the States. California, Oregon and New York have bans for 2035 and Washington state even for 2030. The New England states seem to want to ban it too by 2035. Hawaii looks at a 2030 ban.

That would be a third of the US population.

[–] blanketswithsmallpox@lemmy.world 2 points 9 months ago* (last edited 9 months ago) (1 children)

A large amount of car manufacturers are already going electric. They see the change coming.

Most of our big ones by 2035.

[–] MrMakabar@slrpnk.net 1 points 9 months ago (1 children)

That is not quite settled. The development of a new model takes something like four years and the basic tech a bit longer. The more places ban it, the more brands will actually honor their fossil phase out.

[–] blanketswithsmallpox@lemmy.world 1 points 9 months ago* (last edited 9 months ago) (1 children)

Eh, I have a genuinely hard time believing that companies who rely on what's going to eventually be 'free' and 'clean' energy aren't going to capitalize on it and make bank. Especially with the cultural zeitgeist of younger generations hating on fossil fuels.

It's a fools errand to invest in fossil fuels. In the end, those fuels can just be shipped to your local power plant anyway until better nuclear comes along.

[–] MrMakabar@slrpnk.net 2 points 9 months ago (1 children)

The Saudis have active plans to work with car makers to sell super cheap IC cars into the African market. Qatar owns a 17% stake in Volkswagen already. That might be used for similar purposes.

[–] blanketswithsmallpox@lemmy.world 1 points 9 months ago

Africa is prime for solar in large swaths of the continent though. It's really only rainy seasons when it gets sketch which can be supplemented.

It takes that Chinese and Russian infrastructure first though aye.

[–] AEMarling@slrpnk.net 11 points 9 months ago (1 children)

Cars are a dead-end technology that leave too many people dead by collisions and even more from unsustainable infrastructure.

It's crazy to think how far BEV range will be by then too.

Unfortunately, I'm sure far right wing nutjobs will still convince themselves somehow that masculinity is dependent on owning a diesel/petrol engine

[–] floofloof@lemmy.ca 15 points 9 months ago (1 children)

There's also a good chance far right wing nutjobs will run Canada after the next election and make pollution mandatory to pwn the libs.

[–] toaster@slrpnk.net 3 points 9 months ago

Gunna go hard badgering everyone I know to vote this time around.

[–] tunetardis@lemmy.ca 10 points 9 months ago (1 children)

Zero-emission vehicles - which include battery electric, plug-in and hydrogen models - must represent 20 per cent of all new car sales in 2026, 60 per cent in 2030 and 100 per cent in 2035, the source said on condition of anonymity.

So "plug-in" would be PHEVs I'm assuming?

[–] silence7@slrpnk.net 4 points 9 months ago (1 children)

Yes. Same as California rules.

[–] set_secret@lemmy.world 1 points 9 months ago (1 children)

phev should not be allowed. they're not zero emission. Fuck Toyota for knowingly championing hybrid tech which extended petrol cars for decades.

[–] orangeboats@lemmy.world 2 points 9 months ago

Disclaimer: I don't think PHEVs are zero-emission. And I don't know why Canada thinks they are. With that said, let's carry on...

Since hybrid cars have less fuel consumption and the range of those vehicles don't suffer as much in colder climates, I do think it's a nice transitional technology between ordinary ICEs and full battery EVs.

Once we reach the point where charging stations especially fast charging stations are commonplace (it still isn't the case here sadly) though, it can go straight to the dustbin of history.

[–] ultra@feddit.ro 6 points 9 months ago (1 children)

Really based move from Canada.

[–] Ooops@kbin.social 6 points 9 months ago

It's not. It's just acknowledging the reality that with a lot of countries (including the EU) and several states of their southern neighbour putting bans on combustion-engines in place for 2030-2036 that industry will simply be dead.

Not banning them by 2035 would have the exact same result as you simply don't buy anything but an EV when that's the only option left by then.

Liberals announce new thing for Conservatives to roll back in 2026

[–] Cyberflunk@lemmy.world 1 points 9 months ago (1 children)

This is already ded. Anything a decade out will never make it

[–] silence7@slrpnk.net 2 points 9 months ago

It's not a decade out though; it starts phasing in in 2026:

Zero-emission vehicles - which include battery electric, plug-in and hydrogen models - must represent 20 per cent of all new car sales in 2026, 60 per cent in 2030 and 100 per cent in 2035, the source said on condition of anonymity.

The cold weather there is terrible for Lithium batteries. This plan will never hold with current EV tech

[–] silence7@slrpnk.net 6 points 9 months ago

The cold weather there was terrible for gas engines too. It's definitely viable with what we have.

[–] teegus@sh.itjust.works 4 points 9 months ago (1 children)

I drive an EV in northern Norway. No problemo. Most new cars sold in Norway are EVs.

[–] cmysmiaczxotoy@lemm.ee 1 points 9 months ago (1 children)

This is great news to me. I have been thinking that they were doomed in cold weather. Maybe they are well insulated?

[–] teegus@sh.itjust.works 1 points 9 months ago

You would want one that has a heat pump. It does lose range in cold weather of course, but function is never a problem. Mine has a range of 400-500km in summer, and 300-350km in winter.

That said, it doesn't get colder than -15--20°c where I live.
