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 cold weather there is terrible for Lithium batteries. This plan will never hold with current EV tech

I drive an EV in northern Norway. No problemo. Most new cars sold in Norway are EVs.

This is great news to me. I have been thinking that they were doomed in cold weather. Maybe they are well insulated?

You would want one that has a heat pump. It does lose range in cold weather of course, but function is never a problem. Mine has a range of 400-500km in summer, and 300-350km in winter.

That said, it doesn't get colder than -15--20°c where I live.
