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.

Where's the gas car on here? How about steam locomotive?

If I've got to go 300+ miles through the US I'm probably not going on foot or by human power.

If you need to travel that distance, take a fucking train.

Lol. Sounds good. My little brother lives in Birmingham, AL and I live in West Lafayette, IN. My sister lives in Fishers, IN and my in-laws are at one of the northernmost suburbs of chicago. I invite you to propose me travel solutions for my wife and two children under 5 which are better than my electric car.

For reference:

West lafayette to Birmingham: 875 km

West Lafayette to Fishers: 112 km

West Lafayette to North of chicago: 260 km

I would LOVE to take the train or bike or walk. But I think people like you and OP might be underestimating the hostility toward (and unavailability of) public transit in the US outside of Metro areas. I appreciate that there are better answers than my electric car, but it's better than getting in my double wide and double tall diesel truck, no?
