Desert worlds outside our solar system are unlikely to host #life.

This is because an Earth-sized #planet needs at least 20 to 50% of the #water in #Earth's #oceans to maintain a critical natural cycle that keeps water on the surface.

Planetary #habitability hinges on the geologic #carbon cycle—a water-driven process that exchanges carbon between the #atmosphere and interior over millions of years, stabilizing surface temperatures.

Carbon dioxide, which comes from #volcanoes in a natural system, accumulates in the atmosphere before falling back to Earth dissolved in rainwater.

Rain erodes and chemically reacts with rocks on Earth's surface and runoff transports carbon to the ocean, where it sinks to the seafloor.

Plate tectonics drives carbon-rich oceanic plates below continental land and millions of years later, carbon resurfaces as mountains form.

However, if water levels drop too low for rainfall, carbon removal—from weathering—can't keep up with emissions from volcanic eruptions and carbon dioxide levels in the atmosphere spike, trapping water.

Rising temperatures evaporate the remaining surface water, initiating runaway warming that makes the planet too hot to support life.

That unfortunately makes arid planets, with little water and rainfall, within habitable zones unlikely to be good candidates for life.

Freedom of movement and freedom to stay
Entitlement and the Urge to Destroy

* " As the habitable areas of the Earth shrink under climate change and as many governments around the world adopt measures to deport migrants and refugees, it is time to re-examine our traditional notion of freedom. In the Western tradition, freedom is generally understood in relation to space: it is the freedom of movement, and the freedom not to be obstructed in one's movement by the state or anyone else. In The Freedom to Stay, von Redecker puts forward the radical argument that we should think of freedom in temporal rather than spatial terms."

* "The core of fascism is an unleashed logic of property. Its counterparts are not people, but things; its enemies are not opponents, but thieves."

‘Everything is gone’: Israel destroys entire villages in Lebanon

"Rights groups fear tactic of ‘domicide’ trialled in Gaza, where entire areas are made uninhabitable, is being used again "

"The tactic of mass destruction of homes in Gaza, where Israel has been accused of committing genocide, was described as domicide by academics, a strategy that is used to systematically destroy and damage civilian housing to render entire areas uninhabitable." >>

[Martian #habitability ] To celebrate its five years on #Mars, the #Perseverance rover—or rather, the instruments it carries—has delivered data suggesting a warm and humid climate during the Noachian period (4.1 to 3.7 billion years ago).

This conclusion stems from the analysis of aluminum-rich clay pebbles—called kaolinites—discovered in channels carved into the walls of Jezero Crater by water flow: https://scitechdaily.com/new-research-reveals-ancient-mars-may-have-been-warm-wet-and-possibly-alive/

The “shifting of the intergenerational burden” - more frequent and extreme disasters

"The next generation of Australian workers will cop a $185,000 bill over their lifetimes if the country does not act more urgently to address the climate crisis."

“We have been kicking this can down the road so future generations will have to bear more of the impact of climate change and pick up the tab for more climate action and the costs of adapting to climate change."

“At some point, if climate change is not addressed, it poses an existential risk to human survival, so it’s right up there. It’s difficult to imagine anything that could or should be ranked higher.” >>
