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.

Constituency building is absolutely crucial to all of this and often underlooked. It's a virtuous cycle. If you build useful and good infrastructure, people will use it, and the more people who use it the more people who will vote for it and demand it. It's a big part of how car-centric urban design grew so fast and became so sticky in North America, and that same constituency-building is the best way to take streets back for people.

Seeing people on bikes makes people think about biking. Even without the bike paths, being out and about your city on a bike is doing your part to build just a little more constituency for it. On top of it being good for your wallet, the climate, and likely your health.

Now if only I could get the average local bike shop worker to stop being such a colossal gatekeeping prick about ebikes...
