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.

I encountered this blog post on mastodon and I'm wondering what would people's thoughts be on this. It has some strong arguments in favor of SAI.

One country can’t just start injecting aerosols into the stratosphere without every other country on Earth freaking out.

Are you sure about that?

That is what climate change is. Nations pumping what ever amount of co2 into the atmosphere while the rest of the world does nothing.

I'm sure that it would cause international tensions and lots of saber rattling. Maybe it'd amount to nothing, but if China started doing this in the next few years you know the US would freak the fuck out.
