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.

Not saying this to shill for private jet owners, but to shed some light on this. A big part of why private jets are preferable is that passengers can drive up to the plane and just take off immediately. No check ins, no security, no wait times, no boarding times.

Banning private jets isn't easy to do. A more practical solution might be to eliminate security theater, cut down boarding times, end overbooking, and heavily tax private jets.

If the outcome we want is a reduced carbon footprint, we need to focus on things that are actionable, and getting private jets banned is unlikely to happen.
