Research examines the possibility of spraying tiny particles into the stratosphere to block the sun a bit and cool the planet

Every morning, the Keutsch Research Group gathers for a meeting. Eight engineers and chemists give updates on their preceding day’s work: ordering parts, transferring software, untangling an administrative snafu. The whole affair usually lasts less than 15 minutes.

Scheduling vacations and requisitioning supplies do not scream “high stakes,” but the group’s project could someday have major consequences for global climate change. It is controversial, however. Some even fear it could make things worse. Right now the group is waiting for approval to schedule a new experiment in the stratosphere.

Their idea? To shield the Earth with a mist of tiny particles. It sounds like the stuff of sci-fi movies, but since it was first proposed in the 1950s the idea has gained traction among scientists around the world to shield us not from extraterrestrials, as Hollywood might have it, but from the sun. Known as solar geoengineering, the concept is to send planes into the stratosphere — 6 to 31 miles above the Earth — to spray particles that can reflect sunlight back into space and cool the planet.

Working in collaboration with colleagues from the Keith Group — more than a dozen environmental scientists, engineers, economists, and political scientists under the leadership of David Keith, Gordon McKay Professor of Applied Physics at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and a professor of public policy at the Harvard Kennedy School — the Keutsch Group is hoping to uncover some answers about the possibilities of such a scheme with a project they call the Stratospheric Controlled Perturbation Experiment, or SCoPEx.

You have been very effectively brainwashed.
Frank Keutsch — Heterogeneous Chemistry and Ageing of Designer Aerosol Particles to Assess the Risk of Solar Geoengineering
This project proposes laboratory investigations of alternate materials with properties that may make them more suitable candidates for stratospheric SRM. Specifically, the project proposes studies that address direct physical risks associated with SRM, i.e., effects on stratospheric ozone and temperature, and consequences when particles settle through the lower stratosphere into the troposphere, i.e. impacts on tropospheric chemistry, composition and radiation. This only represents one vignette of the risks associated with stratospheric SRM, but it is critical to quantify these risks as soon...

Robert Stavins — Governance of Solar Geoengineering: Advancing Understanding and Action
This project sought to advance our understanding of a key set of governance issues and, it is hoped, move the research community some steps further toward a shared set of assumptions and consensus on options for solar geoengineering governance. The core of the approach was to assemble a group of global experts in a structured dialogue, based on existing and new research, to identify and advance answers to challenging governance questions.

And the video? Don’t believe your lying eyes.

Very true...

Thanks for that info...

you are rare
i use mine as a phone, only

but lots of people have forgotten that there is a sky as they only look down at their phones

Don’t own a cell phone now and I never have.

The nozzles do not release the chemicals through the engines.

I had been skeptical of the chemtrail story for a long time. I'm a pilot and former Boeing engineer. In general...I knew the power-that-be to be extremely guarded about running anything strange through an aircraft engine. Then...an engineer colleague of mine ran some tests on some odd material that was falling out of the sky at his Sierra cabin. Aluminum fibers. Now...I try not to think about it...

Vapor trails from jet aircraft have been around for, well, since I was a knee high plane spotter. The patterns depend on many things, weather, clouds, temperature, wind, fuel used, etc.

This does not rule out a malicious program. There have been recently national scale attacks on food production in Sri Lanka and the Netherlands, and an usual number of big fires in US food canning/processing plants.

It could even be another of these well intentioned but badly thought out ideas, say, to wipe out insect pests, but this has all kinds of environmental consequences.

with "smart" phones, no need to spray
people are making themselves stupid (with "smart" phones)
