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.

Actual use of minivans I see: moving kids around town. 30 miles does that nicely. Road trips are a small fraction of total mileage.

The people I know who own them have been happy.

While it will depend on use case, 30 miles isn’t all that much when the average US commute is 41 miles, and that’s not including that if your moving kids around town your likely going between more than just school work school home, and so will will need more range given the three for four trips on a single charge.

Say for example you start at home, you go five miles to school, another ten to work, ten back from work to school, and your out of battery even before any moving kids aroud town to friends or activities can start. Never mind that the Pasifica lacks a heat pump, so if you live in a place that gets cold your going to be spending a decent slice of that battery on heating.

People tend to charge at work, at least where I am. So it means all-electric except on road trips.

That's downright amazing.

Ya, around here being allowed to charge at work is pretty rare. I can’t imagine it being more likely when the vehicle doesn’t need to.

Having the option of being all electric period is a lot more useful.

I don't doubt that it's more useful in every case other than road trips. But PEHV is pretty good, and it's what's on the market today.
