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.

Can you imagine? A guy deciding that it's forbidden for anyone to try and make our environment and our climate a little better?

And then this guy will tell you with a straight face that he cares about you

The USA is run by psychopaths

If there is one place in the US that doesn’t need to be taking climate change and the expected sea rise seriously it is FL. They are pretty much untouchable given how it is an interior state with high elevations.

LOL! Came here to point the exact same thing out.. What with downtown Miami being so elevated above sea level and all that.

Oh, they are gonna have SO much fun when that levee breaks.

I suppose the Woke DEI Communist Nazi Department of Environmental Resources Management and their ongoing installation of pumps to control the EVER WORSENING FLOODING is next into the woodchipper?

the stupid hurts. please make the stupid stop hurting so much.

Uhm, isn't Florida one of the more flooded states with rising sea levels?

[–] silence7@slrpnk.net 5 points 2 weeks ago

Yes, but the process is happening slowly, and it's affecting left-leaning areas on the coasts more than right-wing areas further inland.

What a putz

Baffling. Wouldn't unmitigated flooding hurt property values?
