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.

To me, this comment completely contradicts the arguments in your previous comment. I'm curious to learn your actual opinion on the matter.

If I have a choice between two flights A and B, based exclusively on CO~2~ emissions, the only thing my selection changes is my body weight/luggage added to the flight. But the emissions calculation (as I understand it) is the total anticipated CO~2~ of the flight divided by the number of seats. And the bulk of those emissions come from lifting the plane itself, not the individual passengers.

The plane still flies whether or not I'm on it, though. So my choice of flight does not really impact emitted carbon.
