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.

California is not a good example of wildfires caused by climate change. California is an excellent example of how not letting natural fires burn over the last few decades has created unhealthy forests full of dead tree/bushes that are now powderkegs waiting to go off.

California, especially things like redwoods, evolved to NEED a cleansing fire every so often. THAT is our natural climate and we have been fighting against THAT for years.

This isn't "climate change". This is "the climate isn't what we humans want so we tried to change it and now we're suffering the effects of that."

There's a significant impact from the higher temperatures.

It's not just the management history, though that doesn't help.
