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.

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.
