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 emissions from the EV are largely because we've not yet gotten fossil fuels out of electric generation.

It’s also confusing because it’s not like there isn’t a electrical grid within a hundred miles of where one would go off roading. Us rural mountain yokel’s actually do have plenty RV parks, hotels with EV chargers, and plenty of other places with household outlets that allow overnight charging.

There are also of course a lot of other reasons people might get an electric SUV, not least of which are that there are actual options in the market segment, no one makes electric vans with sufficient range to make it between interstate and highway fast chargers or minivans period, need to seat more than four people comfortably or seven people total, need at least some towing, need a decently sized cargo space that isn’t seat shaped, etc…

I mean i’d love it if car manufacturers would stop shoving everyone towards high margin SUVs and Pickups, or made EVs in more than large sedan and SUV flavor, but it doesn’t feel like that’s what they’re talking about.
