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.

This is silly, Autopia is not a significant source of pollution. This is like the plastic straw thing.

If you want less problems from cars and oil, build real car-free infrastructure and leave the charming novelty alone, it makes as much pollution as your yard care company does with it's blowers.

charming novelty alone

Noisy and smelly cars exhausting particulate matter into the lungs of children is your idea of a "charming novelty"? Yes, it's a drop in the ocean overall but it's a bad look and Disney should be selling a better future and not just reinforcing our disgusting past (and present for that matter).

And on your leaf blower point, frankly they should be all electric at this point, both because of their pollution but also the extremely annoying noise that people around them have to suffer.

Ever been to a campfire? Roast some marshmallows? Should we ban that too?

There's a huge difference between building a society dependent on dirty death machines, and a play area where death is nearly impossible and people are exposed to (the same pollutants from the vehicles all around the park) for a few minutes. Even if we get past the car era, don't be surprised to see racetracks and car dedicated areas. This isn't going to change overnight and concern about a Disneyland ride is a distraction from important work.

I think California did ban campfires. At least all fire pits in residential seem to be propane now, no more wood.

This is another population thing IMO, campfires aren't inherently bad and are a part of our evolution. They become inappropriate when you have too many people.
