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 scores aimed to predict a property’s risk from a fires, floods and storms, but some in the real estate industry as well as homeowners have called them inaccurate.

Other services, notably Redfin, still use the First Street scores. IMHO, they're decent at a community level, but the property-to-property differences in the First Street scores are not particularly accurate

Yeah at this point just refer any remaining climate change deniers to the insurance companies whose risk assessment algorithms are blaring alarm bells.

Florida is struggling to attract insurers. They aren’t stupid; they need to make a profit to be a business.

IMO we desperately need p2p insurance. The insurance industry as we know it is 100% enshittified by "crony" capitalism and we have no meaningful mechanism for assessing risk and funding solutions. Homeowners insurance is now about as good a deal as American health insurance.

That's the idea behind mutuals and mutual insurance. It's an older idea than you may imagine
