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.

There’s one key villain in the L.A. wildfires. Any student of history knows who it is (www.sfchronicle.com)

Chaparral and grasslands (what that area has) regrow pretty quickly. This isn't problem of fuel accumulating over decades as has happened in the Sierras. You'd need to be removing vegetation every year, which would also kill off the native plants.

The frequent burns are what’s killing the native plants. Burns aren’t supposed to happen this frequently, and invasives are crowding out the drought resistant natives.
