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.

It can help limit how hot the water gets, and therefore how quickly future storms intensify.

I'm curious, what could Florida do to reduce ocean temperatures with this money?

They can limit their own greenhouse gas emissions, by doing things like subsidizing the conversion of homes which currently use fossil fuels for heating, hot water heating, and cooking to not do so, as well as subsidize solar panels on home roofs.

This won't lower temperatures from where they are now, but it does reduce the future increase.

In all honesty, it sounds nice and I am not against the idea, but I really have a hard time seeing it having any measurable effect.

Each tiny drop on its own raises the water level an imperceptible amout. Together they fill a lake
