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 learned recently when looking for new winter tyres for it car that there are three-ish classifications for winter tyres: unstudded, studded, Nordics.

You will end up in a ditch without studded tyres here. In the winters we'll have a constant decimeter of ice on the pavements. The busy roads will have two tyre tracks between a 5-10 cm thick layer of ice and snow, which looks to lead to asphalt. But no, it's the absolutely most slippery ice you will ever come across.

The city buses stopped using studded tyres a couple of years ago for environmental reasons. You almost feel shame hitting the stop button, because the driver has to slow down well before the stop and takes a good minute for it to ~~get~~ slide up to speed again

For reference, somewhere in Västerbotten, Sweden
