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.

Look honestly this is pretty stupid.

The cyber truck is a super expensive, conservative coded, pavement princess car. The people buying it are probably doing so instead of getting an F350 with one of those illegal mods that lets you pipe out black smoke. It's overall a net positive for the environment.

I feel like this is less about the Cybertruck and more about Elon. I get he's hateable, but people just end up feeling lied to when you use BS logic to pretend that the (supposedly) best selling EV pickup in the US somehow needs to be targeted by climate activists. Just deface his private jet or some shit.

No. Both vehicles are absolute trash for the environment. Just because it's an EV does not mean it is suddenly environmentally friendly. The stupid stainless steel alone uses up idiotic amounts of energy to produce and in the end it is still a several ton heavy vehicle instead of some form of micro car.

And no, no one really uses this or an ICE truck in a way that would require them to have one. Even people who haul shit in the back would usually do with a more sensible roofed vehicle, but that would be less "cool".

All of those big cars can and should be a target. If we go with individual motor traffic, then we should use vehicles that are as compact and basic as possible.
