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.

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.

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 10 months ago (1 children)

Yes. Same as California rules.

[–] set_secret@lemmy.world 1 points 10 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 10 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.

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 13 points 10 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.

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

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

Liberals announce new thing for Conservatives to roll back in 2026

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

[–] silence7@slrpnk.net 2 points 10 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 10 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 10 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 10 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 10 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.
