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.

Let me preface this by saying I believe in science. But it’s worth remembering that scientists are people. And science like this, while it may sound cool and promising, obviously carries massive irreversible risks, and that’s before we take the people into account. I don’t care how closely they monitor the experiments. I count these types of trials in the same vein as releasing genetically modified mosquitos into the wild to breed an infertile generation. Sounds like it could maybe work, but the risks and potential unforeseeable knock-on effects are not worth it.

There was public backlash for a reason. And while I’m not normally in favor of catering to a public that is mostly scientifically-illiterate, in some cases the gut reaction is the right one.
