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.

Some places are being hit harder than others. All else being equal, people should move to the places being hit the least.

Wouldn't a side effect of that, if done en masse, be property values and rent ballooning out of control in the safer areas?

A side-effect? No. You're just describing climate-safe housing being more valuable. It's always been more valuable.

In a functional market system, higher rents will result in more housing construction in those areas. I'm not delusional enough to think that the housing market is functional, but that's a can of worms that will exist regardless of the climate problems or not.

Or to rephrase a bit: yes, if people all try to move to more climate-safe areas, then we'll need to build more housing in the climate-safe areas for them to move into. Obviously.

Yes, and this will start happening within the next several years due to climate refugees, whether we plan for it or not.

As a person near the great lakes: No, they shouldn't.
