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.

Right at the start of the biggest energy transition since the invention of gasoline, I might add.

Canada has the same problem. We're too closely tied to the USA and our leadership is also doubling down.

We're so fucked.

Hey, how is potash export doing?

[–] rbos@lemmy.ca 2 points 2 days ago (1 children)

Not an issue I have at the tip of my tongue, so if that's a gotcha, consider me got. :)

no it's not a gotcha at all. potash is like, another thing the entire world runs on. fertilizers and shit. i just have not thought about it, and it may be being ignored right now. manipulated. idk, i am not an expert at that shit right now.

I am not Canadian, but are Suncor and CNRL really not lobbying hard right now? I would have though they are the large players in Canadian oil sand and would be the force behind those pushes.

I feel they don't have to lobby very hard. Kinda got gravity working for them since we're already a gas station for the USA.
