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 more electronics in a product, the easier it is to build in Engineered Obsolescence.

One good thing about traditional ICE engines is that they were relatively simple. If something stops working, it can be bypassed.

Modern ICE and EVs use CANBus and FSB/DAS, which means that the manufacturer has infinitely more control over the vehicle than a vehicle with disparate components that are individually powered and controlled.

This is more of an “old vehicle vs new vehicle” argument, and as EVs mature, the aftermarket replacement parts (such as the OpenInverter project) will be more accessible.

The Automotive industry is seeing the EV boom as an opportunity to fight Right To Repair with the argument that a giant Lithium bomb under each vehicle is too dangerous for lay-mechanics to work on.
