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.

That's comparing apples to oranges. The sienna seats eight people. You have to compare it with the highlander, which starts at 39K. The rav4 is better compared the camry, which starts at 26K or the corolla

I mean you're illustrating the same rationale in a different way. Anyone who's hauled kids around in a sedan knows it sucks, so you go shopping for a family hauler. Traditionally you get a minivan, so you check the price, and it's nuts. You look at their SUV selection and you find a hit. Three thousand over a camry via car-payments is cheap compared to straining your back every day.
