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.

People need to abandon shell. Bicycling is great.

Bicycling is great.

Only if the cheap infrastructure is good. It's almost always terrible except in the Netherlands. I don't think Copenhagen has good cycling infrastructure btw and I did cycle there. Even in the Netherlands there's still loads of issues.

Bicycling should be pushed (and frankly, at this point forced) by the government. Loads of car infrastructure should be tore up and replace with cycling infrastructure. Cities should change those dead suburbs into places for people by making small modifications. Allow multi purpose buildings, allow smaller shops and restaurants there, tear up the ultra wide roads and replace them with small single direction roads for cars and add superb walking and cycling infrastructure with more than enought space left for trees that give nice shade...

Oh one can dream...
