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.

Don't come to Canada - we're about to get a pretty extreme Conservative government, and they were notorious for censoring science, especially climate science, last time they were in power.

It's too bad science doesn't have the power these idiots think it does (it's just a process anyway, like running). It might actually decide that they aren't with keeping alive. Alas, it does not have sentience or power.

Dont you have a Parliament that would prevent this?

The US only has two viable parties, and they're both conservative. Canada has several viable progressive parties actually sitting in Parliament.

In terms of who has the power, Canada is not all that different: the first-past-the-post electoral system ensures that smaller parties don't get represented and leaves two parties far stronger than all of the others. And those two powerful parties are a centrish, corporate-friendly party and a right-wing, corporate-friendly party. It's not as insane as the USA, but it's not as balanced as some European countries traditionally have been. Depressingly, even those European countries are lurching towards fascism these days.

And because most Canadians are paying attention just to Canada and the USA, it never occurs to many people that we could be doing quite a lot better. Or if it does, they react by flipping to the other one of the main two parties, and a few years later they flip back.

Every election in 2024 has had incumbent parties lose vote share or lose elections. Canada is going the same way.

Also the current governing Liberals are center to center-right by European standards.

That's concerning. Maybe as the US starts locking up progressives in concentration camps, the influx of refugees will drag Canadian politics to the left?

[–] ODGreen@slrpnk.net 5 points 2 days ago (1 children)

That would be nice. But historically Canada has been content to be slightly leftward of the USA and to congratulate itself for it. If Mar-A-Gulago comes to pass, Canada will probably be happy with some intimidation and silencing of progressives. At least it's not USA!

I wonder what happened to Canadian politics when a bunch of leftitst anti war US draft dodgers migrated there in the 60s
