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.

With he way people talk about it here you’d think they’re being asked to sacrifice a child to drive below 60th.

New York didn't sell its roads to do congestion pricing.

I know. I just mean in general with how uber capitalist American society seems to be. It surprises me that all the roads weren't sold if to businesses so that a profit could be made. Seems like a massive missed opportunity.

It seems like the forces trying to ensure car dependency won that one. I'd have much preferred a history of expensive roads because we'd have more walkable/bikable/transit oriented development this whole time.

If the roads were private they'd have either made walking along them chargeable or just banned that.
