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’m almost at the stage of being really interested in how fast the changes will happen. I wasn’t expecting to see so much change over the last 20 years and the next 10 look to be turbocharging.

That said, I really worry about the world my grandkids are going to inherit.

My wife and I opted out of the procreation game, mostly because we could see where things were going when we were in our twenties.

We get to watch the fall of civilisation in real time, and point and laugh guilt free where applicable. Watching what happens to the US over the next 20 years will be fucking hilarious, for example. Watching as it turns to desert from the core outward with supertornadoes peeling strips off and hurricanes that redefine measuring scales pulverising chunks of what isn't literally on fire. The parallels with the evangelical nutters' fairytale God tier smiting will be something to behold, and I am totally here for the whole thing.
