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.

Screenshot of some of the fires currently burning on the US west coast...

EOSDIS Satellite view of the west coast: Satellite view of smoke on the west coast, and fires marked with an orange dot. There are a cluster in northern CA and souther Oregon, and another in British Columbia. All spew smoke, making the first, second, and third quadrants of the satellite image hazy

My first photo shows all fires, including new within the last 24hrs that are still <1 acre.

This is everything over 100 acres.

S01e01 of “extrapolations” feels very close now.

Such a great show...the later episodes are terrifying

Wrong. Eventually everything flammable will burn away and they wont have anything to worry about.

It doesn't work that way. You let unmanaged burns happen and it converts forest to chaparral and chaparral to grasslands. The resulting plant communities grow a lot when it rains, and then burn when they dry out

I was just goofing.
