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.

So stupid. It’s not the stupidest thing that Trump has done this week by any means but it’s still foolish. There’s the obvious environmental component but there’s also a business/economic argument for increasing fuel standards and phasing out ICE models. The car companies were fine with the Biden CAFE standards because that’s what they need to do anyway.

California was probably doing car companies a favor by banning ICE vehicle sales in 2035 and giving them a nudge. By 2035, ICE vehicle sales are probably going to be banned in half the world (and maybe all developed nations save a few petro-states). Most automakers are probably planning to be essentially EV-only around then because they want to export vehicles and ICE cars are going to be a shrinking, niche market even in the U.S.
