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.

Exxon’s own scientists foresaw these fossil fuel-driven anthropogenic changes about a half- century ago, but we’re still not ready for them, and neither are most of our fellow creatures. If I learned one thing from writing about wildfires, it is that this hotter, less stable world is not the “new normal.” We are entering clima incognita — the “unknown climate.” Here be dragons, and some of them are fires 20 miles wide.

My earnest advice is to listen to climate scientists, to meteorologists, to fire officials. They are trying to save your lives. And if you see fire on the horizon, don’t fixate on the flames, pay attention to the wind: If it’s blowing toward you, the embers are, too, and you better get ready to go.

I'm actually quite curious to see how the whole conservative anti migrant/don't mess with Texas/protect our border/secede/states rights/fuck the feds/bravado attitude changes over time as the state becomes increasingly uninhabitable:

Will their propensity for being difficult people force them to continue defending the wasteland from Mexicans, or will they be too busy trying to displace other Americans in more habitable states?

Probably just screaming into the void about “freedom” and “owning the libs” as they either freeze, burn, or drown while voting yet again to restrict the rights of women/LGBTQ/POC.
