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.

The US needs to revisit emissions laws. We need access to smaller trucks. Very VERY few people need a tank on public roads. I'd love to get something like an S10, early 2000's ranger, or an older Tacoma sized truck. My 13" F150 extended crew is the largest truck I feel comfortable owning.

It does make me curious: has anyone seen a survey on how widespread that interest may be? Sure, it’s the practical answer, but i it an answer that a lot of people would give?

Or how much price difference would it require? We naturally expect a smaller vehicle to cost less. The propaganda from one major manufacturer is that a small truck is still as complex and materials cost is small, so they could not produce a small truck for enough less that people would buy it. I know it’s corporate propaganda for sticking with their profit machines, but I suspect there may also be some truth in it.
