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.

New Device Extracts 1,000 Liters of Clean Water Per Day from Desert Air (greekreporter.com)

A new device extracts up to 1,000 liters of clean water a day from desert air, offering a potential backup supply when storms or drought disrupt central systems. The machine, developed by 2025 Nobel Prize winner in chemistry Omar Yaghi, is designed to operate in arid conditions with humidity as low as 20%. His company, Atoco, says the unit can function without connection to the power grid.

The system uses a branch of science known as reticular chemistry. Inside the container-sized unit are Metal-Organic Frameworks, synthetic porous materials engineered at the molecular level.

These materials have an extremely large internal surface area. Even a few grams can match the area of a football arena. That structure allows the material to capture moisture from the air and release it as liquid water.

1000L/day is not enough for a community, you're going to need multiple shipping containers worth of expensive material. Then you've got to put them far enough apart that they don't interfere with each other's operation, and lay a kilometer of pipes from each of them into a central water supply. Maintain the pipes, clean the devices when dust gets on them. Maybe the organic part of the material decays after a while so you need new ones.

It seems implausible that all of this would cost less than a pump, pipeline, well, or even rain water catchment system.

And I'm not thinking of survivalists, I'm thinking of rich people trying to be respectable while preparing for climate change in a selfish way, or coopting 'preparation' for selfishness. Glass Onion types.
