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.

Private jets pollute up to 14 times as much as commercial planes and are undertaxed in US, report says (www.theguardian.com)

"Private flights, used by an estimated 256,000 people (just 0.003% of the world’s population), are the most polluting form of transport, producing direct carbon emissions 10 to 14 times greater per passenger than commercial aviation travel, the report said."

I expect this 10 to 14 times greater to be calculated using the nominal passenger capacities. Since private jets are bound to fly more often at low capacity (to pick up a dress for example), the real difference is going to be much higher.
