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.

because climate-related disasters play such a big role in making insurance expensive, this disconnect also reinforces complaints many people have about the Fed’s approach to growing climate chaos — which is, lately, to plug its ears and ignore it.

Tl;dr: Climate change is causing housing insurance rates to rise, and the price of rebuilding after disasters is increasing. Meanwhile the Fed is doing very little about it because this is Trump's administration, and their orders are to drive us headlong into disaster.

I wouldn't call it a "time bomb," just things getting more expensive per usual.

I can say a condo burned down here four years ago and insurance stuff made it such that its pretty much finally rebuilt but not quite and still not occupied. Its insane. Remember all the talk about russia having crops rotting in the field? US feels like that now.

And yet insurance premiums are higher than ever, and the industry is rolling in record profits.
