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.

Specifically, this shows current and future wildfire risks.

And according to their docs, flood risk coming soon as well. I would love to see projected drought at some point too! Heat and hurricanes are the other main climate-fueled threats, but they're pretty easy to predict (stay out of the South, stay away from coasts).

I like that this project is opening up granular data to the public. First Street is great for simple searches (and their subscriptions are reasonably priced as well), but if you want direct access to their data it's $10K-$15K/year and up.

These maps never include Alaska or Hawaii despite the myriad risks in those places.

The USGS hydrology data in them is lot worse than the lower 48, which makes it a lot harder to do. The whole Aleutian Islands chain is treated as a single hydrological unit for example.

The fire models are also specific to plant community, which means they wont apply to a lot of the situations in those states.
