Geoengineers Plan “would strongly increase side‐effects such as acid rain,” study authors admit.

Geoengineers are proposing to modify Boeing 777 aircraft to spray sulfur dioxide into the stratosphere in an attempt to cool the Earth in the name of debunked, so-called “climate change” — despite fully acknowledging the serious risk of acid rain and other environmental disasters.
A new study published today in Earth’s Future openly admits that this method, called stratospheric aerosol injection (SAI), would sharply increase dangerous side effects like acid rain because it requires “three times more” aerosol to achieve the same cooling effect compared to previous high-altitude schemes.
“However, this low‐altitude strategy requires three times more injection than high‐altitude SAI, and so would strongly increase side‐effects such as acid rain,” the study’s authors warn.
Rather than developing new, specially-designed aircraft to reach the ideal 65,000 feet altitude, researchers from University College London and Yale now propose dumping sulfur at just 42,000 feet — within the existing capabilities of modified 777s.
The ironic catch?
At lower altitudes, sulfur particles would rain out of the sky much faster — meaning a massive increase in the amount of pollutant dumped into the atmosphere.
Instead of solving anything, their plan could flood the atmosphere with even more toxic material, accelerating the very environmental destruction they claim to be fighting.
The study projects injecting 12 million metric tons of sulfur dioxide per year — comparable to the volume released by the Mount Pinatubo eruption in 1991, which famously cooled the planet temporarily but also triggered severe acid rain.
In fact, the researchers admit outright that this new strategy would mean “a proportionate increase in the side-effects of SAI per unit cooling, such as human exposure to descending particulate matter.”
The new proposal to retrofit Boeing 777s to spray sulfur mirrors the large-scale atmospheric modification that anti-geoengineering expert Jim Lee shows is already being carried out daily through commercial aviation’s sulfur-doped emissions.
A Blueprint for Accelerated Environmental Collapse?
Billed as a “shortcut” because it could use existing jets instead of waiting a decade for new aircraft, the UCL-Yale plan effectively opens the floodgates for rapid, poorly regulated deployment.
The study concedes this alarming possibility, saying:
“This could imply an increase in the number of actors able to deploy SAI, an earlier potential start date, and perhaps a greater risk of unilateral deployment.”
Translation: Anyone with a modified fleet of cargo planes could start spraying the skies without global oversight.
This echoes warnings from our past reporting: geoengineering is being normalized as an “emergency solution” — without serious consideration of the unintended, irreversible damage it could unleash on ecosystems, agriculture, and human health.
Acid rain, after all, devastates forests, poisons waterways, and corrodes infrastructure.
Even the authors admit that injecting sulfur at lower altitudes would be “a sub-optimal SAI deployment, with strongly increased side-effects, reduced cooling efficiency, and a more polar cooling profile.”
Yet despite these known dangers, the plan is moving forward — with government agencies like Britain’s Aria already preparing field experiments.
Global Weather Control by Cargo Plane
This is the continuation of a pattern we’ve exposed before: global elites quietly pushing militarized weather control schemes under the cover of “climate crisis” narratives.
First it was experiments on cloud seeding, now it’s mass-scale sulfur dumping using commercial airliners. The researchers wrote:
“Our results suggest that a deployment of low‐altitude, high‐latitude SAI could halt the increase in global mean temperature under current warming rates by redirecting a small fraction of the production of existing large jets (~2 new jets per year).”
In other words, they are planning for a future where the skies are permanently hazed with chemical aerosols, maintained by a growing fleet of retrofitted jets.
Once this kind of geoengineering begins, it can’t be easily stopped. The sudden cessation of sulfur injection could trigger abrupt, catastrophic warming — known in scientific literature as the “termination shock.”
This isn’t a solution.
It’s engineering dependence on a dangerous, destructive atmospheric intervention.
The Bottom Line
Geoengineers are openly admitting that they want to retrofit Boeing 777s to spew toxic sulfur dioxide into the sky, risk widespread acid rain, and destabilize the global climate — all to patch over the failures of industrial policy.
If the public doesn’t push back, the same establishment that wrecked the environment with reckless industrialization will now finish the job under the guise of “saving” it.
Martin comments: stratospheric aerosol injection otherwise known as Chemtrailling! So, we tin-hatters were right all along…again…
This “plan” is nuts.
My parents’ generation, in the UK in the 50s and 60s, remember well the deadly “London Fog” caused by sulfur dioxide from coal fires. So this is quite openly a plan to destroy the planet and all life that resides here EXCEPT for the few that are herded into domed cities. Which are the next logical step from the digital prisons we are currently being fenced into. Logans Run.
