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.

The nation’s electric utilities release vast quantities of the world’s most potent greenhouse gas. Recycling efforts could slash emissions at little cost, an Inside Climate News analysis reveals.

Not saying this shouldn't be reported and addressed, but the headline makes it sound like China's electrical infrastructure is killing us all, when the situation is more like, China's electrical infrastructure could be much better without much extra cost.

The CO2 equivalent the article is talking about is less than the CO2 of emitted by cars in California alone.

It is probably enabling renewable energy consumption all over the world too, so is probably making up for those emissions by reducing CO2 consumption elsewhere.

So the headline makes it sound like China is cooking the planet with this stuff, but that's like calling out one person's fart and screaming that it's stinking up the shit factory.

We should try and do to SF6 what we did with CFCs. True, CFCs are still being released, but international regulations have been really effective in a massive reduction in general

For whatever its worth, SF6 is listed in the Kyoto Protocol.
