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.

seems like they could make that a solar panel and a flat battery at the same time as being a sail

Solar yes battery would be a problem from a weight stand point. That much weight that far out could cause acrwy things.

In the other hand hard say of the solar would be that useful for the cost to install since there is no guarantee it would be facing the sun correctly. Creating a deck cover of solar though could be useful.

I think these new fangled bendable solar panels might work. The bog thing to know is that cargo ships already are diesel-electric, so you can just immediately consume any generated electricity (reducing load on the engine and saving fuel).
