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.

Unfortunately, I think the United States will take exactly the wrong message from its internal climate refugees.

Lifeboat ethics.

"We have to close our borders and deport refugees from other countries so we can help our own climate refugees."

Most people won't take climate change or global warming seriously until it directly affects them.

In a sane functioning world, our political leaders should be sounding alarm bells and reigning in big major corporations to try to gain some control over the problem. Because even if we did shut down everything right now and started actively working towards cooling down the planet, it would take a generation or two before everything went back to what it was a hundred years ago.

The biggest effect that most of us will feel in the coming years is mass migration. We'll start seeing people moving around to places where they are unwanted and uninvited, first temporarily and later permanently ... and then we will start seeing how we will all live with global warming.
