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.

Yes, this means a ton of carbon ends up in the atmosphere instead of in the trees. The right move would be thinning and prescribed burns, but this administration isn't going to do that.

Already bad enough here in Ontario with Doug "I'm a big Republican" Ford's Ministerial Zoning Order addiction, gutting environmental protection agencies, trying to sell off the Greenbelt, using covid recovery bills to get his dirt done, etc.

Any rein we've been able to keep on the timbit would dissolve into nada if we allowed the US govt to run their game here. I can't even conceive of much worse they'd make the tar sands in Alberta. 90% of the fisheries would just be trawlers digging up seabeds. Plus the dizzying amount of toxic waste they're already legally dumping here and in Mexico?

Elbows up.
