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.

I personally might to be honest. If the pricing was similar and one airline had a lower carbon print I would choose the lower carbon print. (people like me is probably why they don't supply this info normally)

If there were enough people like me they would start cancelling flight lanes like we are seeing with the tourist trade with Canada and Florida. Air Canada alone has canceled over 10% of its CA to FL based flights due to lack of flyers (only about 20 flight lanes though, but that's still a good start).

Price and emissions tend to track one another, as the price of fuel is heavily baked into the cost of the seat. And everyone flies the same aircraft models. It's not like there's a "Low Emissions Boeing" or "EV Airbus" you can select.

I agree with that on direct plans. I don't agree with that on indirect lanes. the emissions to passenger ratio should be lower on a full 130 passenger jet that is going to another more populated airport nearby, and then hopping to the destination port with a lower passenger count(this would raise ticket prices some, but I wouldn't expect game changing amounts), than a direct flight plan that has a full jet one direction, and then only 1/4 occupancy on the direct route back.

I don't actually care about full emission count though, I just want the emissions to be used responsibly. a low passenger to emission ratio would be what I find the most useful, but I doubt its what anyone would actually supply.
