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.

If that 1000 liters of water doesn’t stay in the desert, will that make the desert even more arid?

it could affect plants and wildlife that survive on small amounts of water vapor.

But this would be more practical in regions surrounded by salt water.

Not an ecologist: my assumption is the only ecosystem intensely vulnerable to harm from moisture extraction would be fog deserts. Since they’re wanting to set these up on islands, it sounds like it shouldn’t immediately cause an ecological collapse or anything like that.

It must to some extent, could potentially be minimal though. Plus we should keep in mind that taking water out of the ground or waterways isn’t ecologically inert either. Hopefully some desert experts can assess.
