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.

I really hope we can figure out how to fix that issue quickly, but I don’t really see that happening.

The Texas model seems pretty good, like I’m willing to pay more for renewables. I actually already have elected to do so; when my utility was looking to add another hydro generator, I paid for “extra blocks of power” which were $15/mth. I got 2 for 2 years, so my electric is cleaner now than otherwise, not cheaper but cleaner. It was opt-in, but I’d be happy to have it as just a standard cost of upgrading, as well.

We are all in this together, let’s act like it.

This problem is one about interconnection studies for new utility-scale wind and solar. Texas operates by letting them build, and then telling them they can't sell electricity. That's not great either.

Right move here is to do a planned build-out of transmission to support actual needs.

Right, what I mean is the Texas model of pre-surveying for places they would be a good fit with minor pushback, and then having the projects paid by everyone, rather than some investor who can just flake out.

Their grid is an absolute disaster, so I’m certainly not idolizing most of what they are doing, but the method they follow to get them at least done.. that part is good.
