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.

So there are other D-words. There’s delay. There’s division. Get climate advocates fighting with each other about, like, whether they’re vegans or not or whether they drive a car or not. Get climate advocates fighting with each other so you divide and conquer the movement. That’s division. Delay: “Oh, look, we can fix the problem with geoengineering, with carbon capture down the road. Trust us, we’ll be able to fix it.” So “let us continue to burn fossil fuels now. We will fix it later.” Delay. And that’s what they want. They want people disengaged on the sidelines rather than on the front lines. We see these tactics literally playing out today.

If you're like, "...what does this look like in the wild?" It looks like this, or this, and especially this.
