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.

ACEEE actually thinks that Prius Prime emits the least pollution for cars today, including EVs.

https://www.aceee.org/greener-cars

EVs universally weigh more, leading to more PM2.5 / micro plastics pollution from the brakes and tires. (Remember that Prius / Hybrids also have regenerative braking, so EVs cannot take Regen as an advantage).

Weight is key. Not only for pollution but also for efficiency. Prius / Prius Primes lighter weight allows for higher efficiencies.

Prius is on the list if you look it up and would be in the top 10. But I think ACEEE preferred encouraging people to buy the Prius Prime instead of something.

Yes, the Prius has a lot going for it. I personally would rather have a smaller EV instead, but that's not an easy thing to find right now, either.
