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.

Some aren't too bad. Juiced Bikes and Radpower bikes can be had (on sale, early spring) for as little as $1,100. Aventon sells e-road bikes for $1,000 on sale. Granted, you are gonna have to buy stuff like fenders for some. And right to repair for ebikes is pretty abysmal compared to normal bikes, brand dependent. But Radpower and Aventon have physical bike repair shops and partner shops, and Juiced has pretty standard components and a decent support window even outside of warranty (stuff like batteries being standard across almost the entire lineup, standard wheels, spokes, etc)

If we had stronger right to repair laws, and more cities and towns put in protected bike lanes, you really can travel 20+ miles pretty comfortably.
