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.

The article talks about a plan, which depending on what it includes would vary. In the article one optimistic prediction says 10% the other more pessimistic says 0.06%. Until more decisions are made the real number will be unknown.

Also because aviation is actually not a big part of the CO2 emissions

We should still try to fly less, but there are other sectors that can make a much bigger impact.

Would passenger aviation be included in transport or "aviation and shipping"?

I feel like the latter definitely includes goods transport, but passenger could fit into either category arguably

Based on that graph it's 85% of aviation, so I think it's under aviation, because passengers make up 85%

Awesome, thank you!
