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.

Trudeau deserves all the grilling. He’s made promises over promises about curbing emissions all the while pushing for petrol in practice. He’s losing popularity fast domestically too -- but the conservatives are picking up steam to replace him at the next election. Those ones don’t even pretend to care.

Yeah JT is in a tough spot because the liberals are essentially corporate centrists, they will say lots of lefty fluffy stuff to get elected but then their corporate masters (oil companies primarily) wont let them do any of it. And the only viable alternative for Canadians is the conservatives who will definitely trash the environment completely if they get a majority.
