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.

Not to mention they’re tremendously dangerous for everyone who isn’t inside. The fear of dying in a car crash meets the illusion of safety, when it’s being forced to ride or drive in a car that puts your safety at risk to begin with.

This is what happened with my family. We had a VW GTI and a Golf.. when the kiddo came along the wife wanted an SUV so if we got in an accident the kid wouldn't be automatically dead by one of these fucking monstrosities... I think I'm slowly convincing her that a car might be safe, but VW doesn't make the Golf for USA anymore..

I feel like maybe a path forward would be a long the lines of what someone else has said. Make vehicle registration cost more depending on how big it is.. but who knows...

Now to top it all off because of America's obsession with big vehicles there is still a limited selection of small hatchbacks in the EV zone...

A big truck should require a CDL, maybe not the same class of CDL a tractor-trailer requires, but a significant bar to entry. Automotive lobbies have probably kept this from happening yet.
