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 don't know the specifics here, but when there was a wildfire in my area they did something very similar. It wasn't just the lead time on materials, it's that most insurance only pays to rebuild what you had. You have to have additional coverage for upgrades, I think it's called local ordinance or law coverage, that pays the difference between the value of your house as it was, and the cost of building a new house to current code. Turns out most people don't have enough of that extra coverage to actually meet the expense.

So they made an exception and let everyone build back to the standard they had. Afterwards they changed the minimum for that local ordinance coverage state-wide, and premiums have like tripled since.
