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.

We had -35C for several consecutive days where I live. It has been the coldest winter in at least a decade.

And yes, I know this doesn't say anything about global warming. Just wishing it spread out a bit.

Climate change will go both ways, cold bouts will be colder and warm bouts will be warmer. Cold will be less present on average because of rising global temps but extreme weather patterns will be more common. I assume that's what's happening on your side of the world.

Yep. More energy in the atmosphere doesn't necessarily mean higher temperatures. As a general trend sure. But it will mean more energetic weather patterns. More "outliers" and wild swings stressing everything.

Let's hope that the Gulf Stream doesn't shutdown or we'll be having these cold winters quite often.

That would probably not be a good thing for property prices around these parts.
