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 only reason it's unsustainable is because they are trying to charge less than they should for insuring something in these locations, not built to survive the hazards of them. If insurance companies would stop spreading the cost around to make insuring these properties not cost as much as it should, it would work as the incentive it is supposed to be to change behaviour. By spreading the cost out to people not affected by high risk, they are punishing good behaviour and rewarding bad behaviour.

If they charged the premiums that it would actually take to insure these places based on their risk and their risk alone, it would either be sustainable, or no one would want to pay it.... either way, it solves the problem.
