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.

Warm Air and Warm Oceans Power Storms Like Debby | The heating of the planet is increasing the amount of moisture in the atmosphere. That helps to load hurricanes and other storms with more water. (www.nytimes.com)

I really wonder what happens if/ when the AMOC collapses.

Do we get something similar to the "eye" on Jupiter, where there becomes this kind of "permanent hurricane" in the gulf because it can no-longer dissipate heat to the north? And its just like, shitting storms into the south and midwest and up the eastern sea-board as a means of moving energy poleward.

Probably not; hurricanes tend to move and break up once over land.

That's true, but it's mostly because they're not where there's a lot of water. I think op is saying since there's more moisture in the air, will it ever dissipate, even over land?
