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 just saw a video that showed it's possible the pollution that cargo ships were emitting were actually seeding enough clouds to somewhat limit the sunlight that hit and warmed the ocean. This effect stopped recently when they were ordered to stop emitting so much of that pollution.

If it's true they were actually helping accidentally, we could spray ocean water and the salt could actually seed clouds in the same way.

If it works, it would be like a bandaid on climate change to keep the ocean temps a few degrees cooler for awhile.

That's an interesting idea, but not something I would expect Florida to have much say in.
