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.

car free community

cover photo shows both a car and parking lot

I'm just being pedantic but this just shows how ingrained cars are in modern society that even "car-free" communities need them

Yeah, I agree with you. Being 100% without a car is hard in most cases.

And the answer I see is trains. For the amount of money that does into the car industry (+ multi lane roads, administration, maintenance, etc) we could have super fancy, comfy, fast, frequent, and cheap/free trains.

And people would have more mobility too, at a fraction of the cost and environmental damage.

Trains for long distance + trolleys and subways for local travel. There will invariably be people whose transportation needs require a private vehicle but this combo alone would clear up the majority of cars on the road in my opinion.

The trains in Japans greater Tokyo area were amazing when I went to visit. 99 percent of the time they took like 3 or 4 minites more than taking a car and I didn't need tk worry about parking or driving.
