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.

In the US, moving away from cars is a decade+ project. The alternatives are bicycles, trams, ebikes, walking, trains, busses, and subways.

All of them require substantial zoning changes and a change in focus from transportation departments from car capacity to people capacity and safety.

Most people in the US can't feasibly not drive. A good start are things like my neighborhood. I live 1.5 from a shopping center with grocery store and other essentials, but have to drive there. It would be a minimal change and cost to connect a few neighborhood streets to the back of the shopping center or finish the sidewalk/bike trail that abruptly ends half way there.

Another good start is giving tax breaks for employers that do 32 hour work weeks or even 4 10 hour days to reduce driving.

Another idea is allow for small general stores in residential areas.

Another idea is HSR on easy routes like LA to Las Vegas.

Another idea is trams along long strips with lots of foot traffic like public beaches and Las Vegas boulevard.

Another is to add bollards in cities with bike lanes that are just painted lines on the road so people feel safer using them.

Plus China is repeating our mistakes and building out a massive amount of car-centric infrastructure. Huge disappointment given the amount of resources and wonderful transit they have in major cities
