A US-Israeli geoengineering startup has raised $60m as part of its plan to test ‘sun-reflecting technology’. Critics are warning the new tech could have unexpected negative impacts on global weather and drive “geopolitical conflict”. Supporters, meanwhile, have pointed out it might not do that. 🚨Big News in Solar Geoengineering Stardust Solutions, an Israeli-U.S. startup developing […]

By Willem Moore

If you’re unfamiliar with solar ‘geoengineering’, it’s essentially climate change in reverse. Much like how we’ve caused global warming and other changes by releasing carbon, methane, and other gases, scientists believe we can reverse the problem by releasing particles which reflect sunlight back into space.

In a report titled The Risks of Geoengineering, the Center for International Environmental Law summarised:

   Geoengineering technologies, if deployed at scale, could have profound, unpredictable, and potentially irreversible effects on biodiversity, both through their direct impacts and as a result of compounding and exacerbating existing planetary crises caused by pollution, climate change, and unsustainable land use.

As reported by Politico, this latest geoengineering plan is being led by US-Israeli startup Stardust Solutions. Their technology involves custom particles which the company claims are ‘inert’. They also believe these particles will not accumulate in humans or ecosystems, will not harm the ozone layer, and will not create acid rain.

Stardust Solutions’ founders are nuclear physicists who worked for the Israeli government. Although they insist their new project is unaffiliated with the state of Israel, they are headquartered outside Tel Aviv. This could cause problems for them worldwide given the boycott of Israel which began during Israel’s apartheid era and continued throughout the genocide.

You can't pay musk to do it without the consent of a nation state with launch facilities where the rockets are located and the military permits the use of the airspace.

Nation states jealously guard the ability to launch rockets.

are rockets actually necessary to disperse these aerosols?

You could probably do it with balloons but I assume payload is limited

[–] Euergetes@hexbear.net 7 points 2 weeks ago

there were proposals to disperse these from cargo ships a couple years ago

but yeah, a hot air balloon is extremely cheap and could do that shit easily

has something changed from when they were proposing this on trans-pacific freighters?

That was spraying water droplets into the air wasn't it?

is it irrelevant?
