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.

mention of 9/11Smaller 9/11s would be happening every day if flying cars were common

Also helicopters already exist and they're basically flying cars

What I'm envisioning isn't piloted by the passengers. Set your destination and it navigates following FAA rules and routes over short distances.

It's pretty trivial to detect humans and scan faces. Until things improve r these are going to be single passenger only so not much opportunity for a large payload.

With self driving cars, it's only a matter of time before someone makes a self driving car into a delivery system for a bomb.
