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.

Well, we can pretty much gather as much. A decade ago, two decades ago, the warning was “if we don’t act, in 100 years the world will be in trouble,” and then it went, “if we don’t act fast, we will see catastrophic effects within the next generation” to “this is happening at an alarming rate.”

And in case no one’s noticed, we’ve barely slowed down emissions, if at all. Greenwashing has had a profound effect and people think we’re doing a decent job, on our way to “net zero,” but we are digging a much deeper hole, really fuckin fast.
