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:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Yeah that is far more logical - The pics in your other post illustrate the concept well. The major hurdles are transportation and retrofitting. New towns and construction are well and good but for adoption to take off benefits must outweigh existing convenience and not eliminate mobility overall. Scalability is another one.
It's a lot to try to balance. Designs I've seen get the most traction involve reclaiming blocks and offering elevated rail to move about or use of subway where logical. The more modular the better. And I've seen a few like that get /close/ but they'd strike out on scope or would piss in some lobby's cereal and get early enemies. That one's a minefield.
I feel like we could see some rapid creep if someone got the ball rolling and it was reasonably successful... but that's a hell of a big step to take. And make no mistake - it will be a retrofit that starts the creep. Has to be a city or a substantial dense town to draw interest.
Another major hurdle is the petrol industry & incentives for the few to get rich my building & maintaining roads. Public transport on the other hand (hopefully) doesn't generate profit as it is a service for the people. So those in local/regional/state power have more to benefit (personally , financially) from building roads. It's like taxes, people that influence/write/adopt tax policies are the ones that benefit from tax cuts whereas the majority loses more through all the services they have to pay double for.
It takes civil organizing to produce politicians and high enough demand for such change. Often through things like higher commercial rents or local service fees (like stores in the center pay more for water or waste disposal as they would in a mall outside the city - and the difference pay the customers though cars, time, and well-being).
