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.

While a Trump presidency couldn’t slam the brakes on the E.V. transition, it could throw enough sand in the gears to slow it down. And that might have significant consequences for the fight to stop global warming.

The core policies are:

  • A subsidy which targets cheaper EVs to not-super-rich and limits it to cars with key components made in the US
  • An emissions rule which will effectively force a significant fraction of cars sold to be EVs in a few years
  • subsidies for new factories

Trump will surely get rid of those.

The tariff he hasn't really weighed in on; he seems to think of himself as a mercantilist, so he might keep it.
