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.

It's fine. I'm sure Qatar can just build a giant air conditioned city.

But what about when the rate of migrants dying of heatstroke while constructing it outpaces the rate at which they can coercively import them

What then

as the last football world cup showed us, as long as fans conveniently ignore the truth of exploited workers and lap up the sporting spectacle, the troubles of construction labourers are nothing to worry about.

Throw up their hands and say, "For a brief moment, we created a lot of value for our stakeholders."

IOC: "So, would you be interested in hosting the summer games in 2052?"

City below/above +/- 60° latitude: "Nah fam. We're all booked up boiling alive from now until forever. Maybe try Reykjavik? I hear they have comfortable, sub-100 weather year round, nowadays."

We can maybe do one more but everyone's naked

what about the winter games?

There’s a good chance that those will become too hot for athletes to compete in in most cities (or their former sites) by a few decades later. Of course long before then, the Olympics will have stopped happening as the apocalypse takes hold for real.

Ask me if I am joking, if you are unsure

Even worse because you need a mountain with snow for the skiing, close to a city. That combination is harder to come by when snows worse.

Detroit has been nice all summer and could use the infrastructure investments.

Just move it to spring or fall.
