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.

There are a lot of things we did by hand once upon a time that are now done by computers and motors. Why do you imagine a modern sailing ship would use manpower to raise and lower sails?

Smaller ships would require more manpower per ton, but not as much as was required on classic sailing ships.

Fair point!

I assumed this would be the case, but also did some quick research before I responded. There's a cargo sailing ship from over 100 years ago still in active service. It's called the Avontuur. And apparently, interest in commissioning new sailing cargo ships is on the rise.

That's cool, thank you for pointing out that ship. I only knew of the Tres Hombres which runs under Fairtransport. I've seen some videos on Youtube and got the impression they are financially struggling.

I love those sailing ships of the old times. I find them fascinating. If you love them like me, this is a real gem of video material commented by a sailing captain.
