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 remember arguing with Indians on Reddit 10 years ago who spouted stuff like: "The West polluted first, it's our turn now to develop our economy!"

That's gatekeeping, colonialism and victim blaming.

A lot of idians, virtually the same amount even would die if they did not develop their country.

Poverty by choice is not a solution to global warming, but may trigger wars and ethnic cleansing.

Jesus. We're almost at the Ministry for the Future-style wet bulb event, aren't we?

There are regions at very high risk: India and South Asian cities, Rio de Janeiro, West Africa, Mekka during the islamic Haji.

But a combination of wide-ranging power failure around a big city and extreme heat could also become deadly in places like the US.

And IIRC heat deaths are often not recognized, heat stroke fucks essential body systems and the consequences might appear days later and be classified as heart attack or circulatory failure.

It probably won't look quite like that because cheap solar is going to power air conditioning at a scale which gets most people through it

This is about a twentieth of their birthrate, just in case someone else cannot comprehend dying on a population scale.
