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 say we build new, people centric cities, move to them, and tear the old ones down. Or find ways to uproot the roads and replace them with useful infrastructure. I agree with you, the thing that sucks (in the US) is our cities have all become car centric tombs that stretch for miles on end.

This would be effective. Altering the way we designed cities would allow new developments to abandon roads. Create walkable areas connected to an overarching network of high speed rail. As more sections go up, population will fill it, and priority can be given to residents that need to move to make way for the next redevelopment section.
