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.

@silence7 I feel like this story is a repeat from maybe the 1980’s

Yeah, GM was working with California in a fairly constructive way for several years. This is a major flip from that.

Wow GM fighting EVs....who would have thought?

It's a change from their recent position; they were one of the automakers which worked with California on an ICE phase-out starting 2019.

Remember when GM crushed all their EV1s? Pepperidge farm remembers.

Remember when they used OnStar to track and then sell their customer's acceleration and braking data so their insurance rates would go up?
