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.

At least in Europe, there are a few big reasons. First and foremost combustion engines are more profitable. EV require a lot of R&D and factory investment, which is not needed for old school combustion engines. The other part is a shrinking car market. Covid means a lot more work from home and at least in Europe, you generally have the option of doing a lot of things on foot, bicycle or public transport. At the same time, when you drive less you do not go for a new car as quickly. Then you have cost. Due to supply chain issues battery prices have not fallen quickly enough. There was a bit of time, when they were stable. Good news is that they are falling again.

In other words, this is a difficult transition and some car makers are going to fail.
