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.

If we persist in delaying key measures that are needed, I think we are moving into a catastrophic situation, as the last two records in temperature demonstrates (...)

You were provably joking, but now Im curious about what a scenario where the climate being out of control can be a good thing. Not in a snarky way but in an speculative sci-fi way.

Maybe some kind of Gaia disasters-hitting-fossil-fuel-infrastructure-and-palaces situation?

Probably by giving humanity a second chance at not being resource-hogging assholes.

Won’t be much of a second chance. We are globally tied together for manufacturing, raw materials, farming, food, and the specialized knowledge to put all these things together. lf CC ends up in a worst-case scenario it will cause the global supply chains to collapse and result in truly catastrophic starvation and collapse of civilization as we know it. It might be possible for places like china to hold out as they’ve got a lot of resources and manufacturing all under one roof, but other places that are reliant on that manufacturing capability being shipped to them are fucked. I wish I could find it, but there was a legit paper done on just such a situation that described how the breakup of the flow of materials around the world would result in disaster.

China will be hit pretty hard by climate change I would assume. Most of their population is located in the southeast coastline of the country. It is already hot over there, if it warms 3-4 degrees they might hit a point where you need AC to just survive. Probably a lot of those people would need to be relocated. That sounds pretty hard to achieve in a short timespan.

Yeah, that's pretty much what I mean. The collapse of civilization will give the survivors a chance to reconsider what led them to being "survivors" in the first place. At least for a few generations.

Yes, I was joking, in a "this party is out of control" way... and we're drinking... capitalism?
