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.

Yeah but the wildfire situation won’t get better any time soon, even if we stopped all emitting today. You need controlled burns. A small controlled burn is a hell of a lot better than a massive uncontrolled one.

Right. I agree that controlled burns are necessary, and firefighters already do them. My point is that those things are addressing the symptom of increased wildfires, and people are "ignoring black carbon," because it's not a viable path towards meaningfully addressing that specific issue.

Wildfires won't ever completely stop just because we switch to 100% green energy, but this article is looking at the problem from the wrong end.

But they haven’t been doing controlled burns, that’s part of the issue. At least in the USA, controlled burns stopped for a long time. Now we have forests that are too dense
