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.

Sure, they don't represent much compared to all flights people take just to go on vacation though...

Heck, your emissions are lower by driving to your destination with four passengers in a full sized truck or SUV than they are by having the same four passengers take a plane.

Consider the time wasted at the airport and if you're traveling a distance that can be covered by car in a day you're better off driving alone in a small car to get there.

Airplane manufacturers invest in anti emissions tech only to look good to authorities, none of it gets implemented in the end, might as well drive a car from the 80s on which the converter has never been changed, you'll probably pollute less for the same distance travelled!

This is what I tell everyone. By the time you arrive at the airport. Go through security. Wait on the plane, then reverse that when you land, there's a lot of added time there.
