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.

Black and white cartoon.  Left panel: a group blocks a road with a banner reading "No new oil | so there's a liveable planet for our children."  Right panel: A boardroom, with members of the board raising their hands.  In front of them is a chart showing planned oil extraction going well above a dashed line marked "Level beyond which there will be no livable plant for our children.

Sudden drastic population reduction would solve the problem as well. Historically that's been how these things are done.

I read about this concept in a book about Ecofascism. The problem with that Malthusian way of thinking is this: Who will we leave behind? How are we gonna implement eugenics? Capitalists are a clear minority, and most of the global south seems to be an excellent target for answering that question.

A better way to look at the problem is to de-escalate and simplify. I mean, if you care about your fellow human beings.

Most of our work is already bullshit, and our industrial capacity (for the most part) can give us nice stuff. At the same time, we get rid of the high-polluting options. The world's population would self-regulate in horizontal societies just because everything has been that way historically. The phenomenon of hyper-poblation is a centralized-power thing.

Local climate change has caused famines in various places throughout history and pre-history. Thus decimating the local population.

This time it's global. And as always the poor will suffer the most. In a couple of decades Europe and the US will close their borders. Because they can't feed the millions of people coming over.
