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.

40% of global ship traffic is simply moving fossil fuels around! Renewables make much of this traffic obsolete (slrpnk.net)

"We need the fossil fuels to get more fossil fuels to move the fossil fuels just to take the fossil-fuel thing to the fossil fuel store to get more fossil fuels!" -people that sell fossil fuels

It's the rocket ship problem.

You need fuel to move the fuel that moves the fuel that moves the rocket

Sure, but when a lot of the things don't need to carry the fuel with them and induction roadways do it all in the moment?

And one day we even become fossil fuel...

We don't, we decompose. Fossil fuels are basically plants that died and were subsumed millions of years before bacteria and fungi evolved to decompose them.That doesn't happen anymore.
