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.

Even without accidental site leaks, the infrastructure itself leaks terribly. Residential fossil gas systems are constantly venting tiny amounts of methane from throughout the system, with occasional major issues that can go days or weeks without notice until a sniffer van or something like it catches it. This happened at my house just recently -- my gas was fully capped off the week I moved in, but a guy showed up now several years later from the utility and said he was there for a detected leak and he had to remove the meter and re-cap everything. The whole time trying to convince me that gas stoves are better than my undeniably-superior induction one.

For all I know it was venting at a decent clip this whole time. Nothing I could really do about it. It's not like I was checking the meter what with my no service, and as far as the guy could tell the leak was from before the meter anyway.

And it'll get worse as the systems are used less. A smaller subscriber base means these companies will inevitably cut repair and maintenance budgets, leading to more leaks. More methane. The only safe and sensible thing to to have public takeovers on them and then immediately start working to decommission.

I'm wondering about all the campers and RVs that are propane reliant, and heating around the globe that is propane reliant. I guess occupants of dwellings will largely be left to sort things, without much financial aid incentives.

Propane's a different thing. It's just trading in bottles. Those bottles will keep being available for a long time and are, frankly, not a major emissions source. Still one we should get rid of, but it's not a low-hanging fruit. Propane is also still one of the more climate-friendly refrigerants, so it's definitely sticking around.

As far as people in situations like that relying on fossil gas distribution infrastructure... one way or another they're going to be left holding the bag.

Electrified appliances are almost universally better for consumers both in quality and economics. Electrification and gas-free new construction will keep happening. Keep accelerating.

The infrastructure of gas is already built. It costs a lot to maintain it even as poorly as they do. As fewer ratepayers are using the system, the remaining ratepayers have to pay a larger and larger share of that cost -- making the gas even more expensive and an even worse choice for consumers. Inevitably, the poorest folks who cannot afford to replace their appliances but also cannot afford to keep using gas will be left behind. That's the reality of the privatized system we have.

I feel bad for all the people who are going to get fucked, especially since for many it was bogus that they were saddled with fossil gas in the first place (e.g., bribes to builders/subdevelopment managers).
