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.

Climate change isn't producing expected increase in atmospheric moisture over dry regions: Study (phys.org)

The laws of thermodynamics dictate that a warmer atmosphere can hold more water vapor, but new research has found that atmospheric moisture has not increased as expected over arid and semi-arid regions of the world as the climate has warmed.

The findings are particularly puzzling because climate models have been predicting that the atmosphere will become more moist, even over dry regions. If the atmosphere is drier than anticipated, arid and semi-arid regions may be even more vulnerable to future wildfires and extreme heat than projected.

The authors of the new study, led by the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR), are uncertain what's causing the discrepancy.

"The impacts could be potentially severe," said NSF NCAR scientist Isla Simpson, lead author of the study. "This is a global problem, and it's something that is completely unexpected given our climate model results."

Wasnt that the basis for Interstellar?

Oh hmm… I thought they were having some sort of problem with a blight that was wiping out all the commercial crops one-by-one until only corn was left. And then the NASA researchers realized even corn was on in trouble. But there was a lot going on in that movie that was hard to follow, so I'm not sure. Maybe there was a climate angle?

Going back to the lethargy idea, one could also surmise that when the rain does work its way inland, you could get more than you bargained for because the system will stall again and dump on one spot rather than moving on. At least that sort of tracks with what we've been seeing.

Might have confused it with Grapes of Wrath and came out with a weird conclusuon, been a while on both
