Solar geoengineering by injecting aluminum oxide aerosol into the lower stratosphere is a serious threat to global mental health

Dear Editor

A possible geoengineering method to mitigate the global warming aspect of climate change is the injection of aerosols into the lower stratosphere, closely mimicking the way large volcanic eruptions cool the climate. This method is called solar-radiation management (SRM) scheme or simply Solar Geoengineering (1). SRM has been suggested to be affordable and have high effectiveness compared with other geoengineering schemes that have been suggested to mitigate global warming (1). While sulphate aerosols are the most studied, it has been recently shown that aerosols with other compositions, aluminium oxide (alumina) and diamond, could be used to dramatically increase the amount of light scatter achieved on a per mass basis. Alumina particles formed after the alumina aerosol injection are more efficient scatterers and may have less severe technology-specific risks than sulfates. Thus, they are expected to be more efficient per unit mass for geoengineering applications (2).

Nevertheless, it has also been suggested that SRM has a low associated safety compared with other geoengineering schemes because of its possible effects on regional climate, stratospheric ozone, high-altitude tropospheric clouds, biological productivity (3), and global biodiversity (4). We want to add a possible severe effect on Global Mental Health that could be caused by using alumina as light scattering.

The average residence time of a particle in the lower stratosphere is approximately 1-2 years (1,3). After eventual transport into the troposphere, alumina particles undergo relatively rapid mixing processes by weather events, turbulence, and cloudscale overturning. They are mostly removed from the atmosphere by dry deposition, sedimentation, or scavenging by clouds, finally polluting the environment (1).

Aluminium has often been regarded as not posing a significant health hazard if the human body burden of aluminium has increased. Nevertheless, epidemiological studies suggest that aluminium may not be as innocuous as was previously thought and that aluminium may actively promote the onset and progression of Alzheimer’s disease. This condition is the most common form of dementia and may contribute to 60 –70 % of cases. In 2015, dementia affected 47 million people worldwide (or roughly 5% of the world’s elderly population), a figure predicted to increase to 75 million in 2030 and 132 million by 2050. Recent reviews estimate that each year nearly 9.9 million people develop dementia globally; this figure translates into one new case every three seconds (5). Even prolonged exposure to low levels of aluminium leads to changes associated with brain ageing and neurodegeneration (6).

Furthermore, aluminium has been included among 200 neurotoxic chemicals that silently erode intelligence, disrupt behaviours, truncate future achievements, and damage societies, perhaps most seriously in developing countries. The latter is called the “Silent Pandemic of Neurodevelopmental Toxicity in Children” (7,8). Recently, the aluminium content of brain tissue in autism spectrum disorder was found to be consistently high (9), and the prevalence of autism spectrum disorder is increasing, last CDC estimated prevalence is 1 in 44 children (10).

Worldwide land precipitation of aluminium following aerosol spraying into the lower stratosphere would increase human body exposure and seriously threaten Global Mental Health.

July 30, 2022 | Zero Geoengineering |  Who is involved in intentionally polluting our skies and interfering with Earth’s natural weather and climate?  It’s essential to know if ongoing unregulated interventions are actually causing the environmental catastrophe and destruction that we are witnessing worldwide.

When analyzing environmental problems, it’s crucial to scrutinize the role of the last 80+ years of unregulated cloud-seeding, weather modification and atmospheric testing in largely contributing to, or creating current weather and climate extremes.


 NOAA Chemical Sciences Laboratory (CSL)



The US government, many alphabet agencies, universities, private individuals, the UN WMO and governments aroundthe world are engaged in various atmosphericresearchprograms that have remained outside of the context of public oversight and legitimate Constitutional governance for decades.





NOTE: One of the original purposes of weather modification was weaponry. Cloud-seeding and other extremely hazardous atmospheric activities, presently exclude public consent mechanisms and legitimate regulatory constraints, therefore, could be defined as environmental warfare and must be banned.

Could recent Nevada & UAE floods be the result of cloud-seeding?

Could recent Nevada & UAE floods be the result of cloud-seeding?

July 29, 2022 |  | Flood or Drought: How Do Aerosols Affect Precipitation?

According to research, cloud seeding has the potential to cause flooding and drought. A 2020 article asked, “should we be playing with the weather?” reporting on notable flooding events in 2019 and questioning the impacts of chemicals being pumped into the skies.      Source:

Fast forward to 2022 as Las Vegas, Nevada and the UAE are dealing with severe flooding which happened after acknowledged cloud seeding operations. Cloud seeding can use either ground based generators and / or aviation for operations.

NOTE: Dry ice, used for cloud-seeding = solid carbon dioxide = CO2.

Additionally, silver iodide, a common agent used in cloud seeding, is an environmental hazard and also a combustable agent, according to PubChem.


“Even experts admit they do not fully understand the impact of their interventions,” according to a recent article on cloud seeding in Dubai. The article also states, “Every time it rains in the UAE, some residents are quick to speculate that the wet weather was caused by the country’s cloud-seeding programme.”







Downtown Las Vegas sees flooding in late-night July storm

July 28, 2022 | By Marvin Clemons | Las Vegas Review-Journal |


Heavy rain caused flooding in downtown Las Vegas and elsewhere Thursday night, the second evening of monsoonal storms in the valley.

Several valley locations received more than an inch of rain during a turbulent two hours. The strongest wind gust was 71 mph at Flamingo and Eastern, said meteorologist Barry Pierce.

Two cells moved into the south suburbs shortly after 10 p.m., one over Henderson and the other near Sloan.

At 10:12 p.m., NV Energy reported about 7,300 customers without power. Most were in central and eastern parts of the valley. There were unconfirmed reports of water damage inside the Circa sportsbook and Caesars.

In the storm’s aftermath, about 15 intersections or streets were closed as of 11:35 p.m., according to the Metropolitan Police Department.

Downtown damage

A Review-Journal photographer said all of the lights on the Fremont Street Experience were out as well as some lighting at the Golden Nugget.

Winds were blowing 40 to 50 mph in downtown Las Vegas around 9 p.m. A gust of 54 mph was recorded at Decatur Boulevard and the 215 Beltway on the north side, said Trevor Boucher of the National Weather Service.

Around 9:45 p.m., Metropolitan Police Department Lt. Aaron Lee said there were about eight vehicle crashes valleywide since the rain began about an hour earlier.

“Sufian Farrah, meteorologist and cloud seeding expert at the NCM, acknowledges that cloud seeding operations increased rainfall in the UAE but said they didn’t cause any flooding. “We only enhance the amount of rain; we are not creating floods. Even some clouds we avoid seeding, because it would be too dangerous for the aircraft to penetrate them,” he told WIRED in November.

“These clouds usually contain a lot of water and can cause floods. These sorts of clouds we avoid… We are concerned about [seeding clouds that could cause flooding]. We are using very sophisticated radars that cover all of the UAE’s atmosphere and we are monitoring every droplet falling from clouds in the UAE.”

According to other experts, though, it’s hard to be certain of anything when it comes to cloud seeding.

“It’s a really difficult thing to [directly link increased rainfall to cloud seeding],” says Jeffrey French, assistant professor of atmospheric science at the University of Wyoming in the US. “For the last 60 years, people have tried to link precipitation directly to cloud seeding. And the problem, in a statistical sense, is there is so much natural variability in precipitation; particularly in warmer clouds, like those that they’re trying to seed in the UAE, there’s a lot of variation that occurs naturally and that we as scientists can’t necessarily explain.”

French was one of the scientists behind a 2017 project called “Seeded and Natural Orographic Wintertime Clouds: The Idaho Experiment,” or SNOWIE, one of only a handful of experiments seen by the atmospheric science community as demonstrating that cloud seeding can work in terms of making precipitation fall out of a cloud—in that case, snow.”
