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.

I'm of two minds about this. If an area is extremely disaster-prone, you shouldn't build there. But it sucks to already live there, and not get insured. I'd be fine if there were no new insurance contacts on new houses being built.

Another, local example: in Germany, a few years ago there was a catastrophic flood that killed several people and destroyed many houses located in a river valley, because the river had been artificially narrowed and straightened. With looming climate change there was already talks about flooding risk and insurance covering. After the disaster, a decent chunk of people planned to rebuild their houses in the exact same spots. Some were not even insured, and relied on government disaster relief money, afaik
