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.

Thanks a lot, captain obvious. We did the calculations, thanks for repeating fossil industry propaganda.

It's not propaganda, it's an unfortunate fact of almost all industrial processes that they require oil based products at one stage or another. I don't like it either but until/if these technologies can rely on renewable alternatives for such processes, they're not really green or renewable, and neither are the electronics that they power. Everyone seems to conveniently forget this. If you want true green technology and renewable energy, you're going to need to give up industry altogether. Which we'll probably end up doing when the coming climate catastrophe forces us all back to the stone age.

Even if they do, they massively cut down on total pollution. They don't magically produce more pollution in one manufacturing process, than all the oil they are replacing that will be burned. That's nutzo.

As I already stated, yes, they are better than say, a coal burning power plant. I'm not saying otherwise. But I'm pointing out that solar panels and electronics in general still require many polluting and non-renewable resources and processes to create. And solar panels wear out eventually, like everything else. So yes, you're burning less fuel, but it's not "zero emission" or "sustainable" (currently) for their production or their eventual replacement. I'm just annoyed by the way these technologies get pushed as an almost magical alternative to fossil fuels when fossil fuels and chemicals are still required to make them.

And when they wear out they can largely be recycled

Mining equipment does not strictly need to be diesel powered. Rest of solar manufacturing uses electricity and heat, that also doesn't strictly need to be fossil fuel powered. When oil is used for plastics/tires/asphalt it is not burned and so does not create emissions.
