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.

China's ultra cheap EVs are subcompacts that are extremely well suited to small batteries to keep them cheap, while having good range/mileage. Small batteries can work for EVs if there is good charging infrastructure. Europe, being densely populated, is suited to having good charging infrastructure on heavily used highways, and "drive through small towns" which have cafes and restaurants suited to recharging at EU life pace.

EU/French car history is ultra well suited to small cars, where cities have narrow streets, and affordability has always been popular.

EVs with small batteries, even in EU/US, can be built cheaper than ICE vehicles by domestic brands. Battery costs are falling everywhere, but licensing/importing Chinese tech to bringing battery costs down, is path to domestic EV industry success/growth. EU is especially vulnerable to geopolitical oil extortion, from both friends and foes.
