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.

Challenging this. Maybe the problem is the constant appetite to change your car every year? Maybe if there was a push to have consumers keep the same car for 10 years (I've had mine 11 now) it would be overall better for the environment. I'd argue the biggest impact on the environment around automobiles is the energy taken to create it, not to use it once it exists. This is what worries me with the push to electric. Perhaps we shouldn't be pushing people to continue the same model of disposable vehicles except now they're electric. Maybe we should stop people treating vehicles like they're disposable.

This is my same belief with phones, computers, etc.

We have an underlying problem with how we treat things as disposable.

It takes significantly larger amounts of pollution, energy, resources to produce these ridiculously large vehicles that are in many many use cases not the best tool for the job of transporting 1 to 5 people. Driving a vehicle for a longer time doesn't change this. Drive a regular sized car for 15 years or longer.

Correct me if I'm wrong but most of times when they dispose of a vehicle they sell it someone else to use right? So the only waste for that person be the rapid loss in car value after buying it new. Or are a lot of these cars ending in the dump?

Frequently changing vehicles is wasteful to that person’s weatlth but the vehicle stays on the road just as long. For the rest of us, this behavior just fills out a fpbigger used car market
