Drastic and Irreversible Climate Geoengineering Worries Scientists
An American company is already sending balloons filled with sulfur dioxide into the stratosphere. NASA is considering flying ice into the atmosphere.

The Earth is too hot and only getting hotter, according to governments and global bodies such as the United Nations; and the efforts to reduce carbon dioxide aren’t having enough of an effect.

“The world is passing through the 1.5°C ceiling and is headed much higher unless steps are taken to affect Earth’s energy imbalance,” James Hansen, previous director of the NASA Goddard Institute for Space Studies, said in January.

Thus, to buy more time, on Feb. 28, scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA) released a report detailing a solution called “intentional stratospheric dehydration,” or in layman’s terms, flying planeloads of ice to 58,000 feet and spraying ice particles into the upper atmosphere.

“It’s a very small effect,” said lead author Joshua Schwarz, a research physicist at NOAA’s chemical sciences laboratory. “Pure water vapor doesn’t readily form ice crystals. It helps to have a seed, a dust particle, for example, for ice to form around.”

The researchers report that by dispersing small particles, or what it calls ice nuclei, into areas of the atmosphere that are both “very cold and super-saturated with water vapor,” water vapor in the atmosphere will “freeze-dry” and rain out of the atmosphere as ice crystals, cooling the planet.

The proposal is known as geoengineering—and NASA and NOAA’s joint plan is far from the only idea that’s jumped from the pages of science fiction, à la the 2013 Hollywood film “Snowpiercer,” to mainstream science.

István Szapudi, an astronomer at the University of Hawaii Institute for Astronomy, has turned to essentially geoengineering a giant parasol, or what he calls, a “tethered solar shield” to shield the Earth from a portion of the sun’s energy.

“Any sunshield works by blocking a small fraction, circa 1 percent to 2 percent, of sunlight reaching Earth,” Mr. Szapudi told The Epoch Times. “This is an almost undetectable amount by looking at the sun, but it would still cool the atmosphere to pre-industrial temperatures according to climate models.

Specifically, the tethered sun shield is a solution that is lighter, thus cheaper, by many orders than traditional designs.”

Technology entrepreneurs Luke Iseman and Andrew Song of Make Sunsets have already taken action and have been creating reflective, high-altitude clouds by releasing balloons full of sulfur dioxide (SO2) into the stratosphere, what they call stratospheric aerosol injection (SAI).

“With climate change rapidly transforming our world, it’s crucial that we prioritize action over words,” Make Sunsets stated on its website.
“We believe that SAI is the immediate, necessary solution to cool the planet and buy us time to transition to a more sustainable future.”

But scientists such as Christopher Essex, emeritus professor of applied mathematics and physics at the University of Western Ontario and former director of its theoretical physics program, said carbon dioxide (CO2) isn’t the driver of Earth’s warmer temperature and that such geoengineering measures are “extraordinarily dangerous.”

“I used to run a climate panel for the World Federation of Scientists,” he told The Epoch Times. “And we had one session where we presented on exactly why geoengineering is extraordinarily dangerous. It’s a crazy idea.”

Ian Clark, emeritus professor for the Department of Earth and Environmental Sciences at the University of Ottawa, echoed Mr. Essex.
“Geoengineering the climate is a very scary prospect,” he told The Epoch Times.

“It’s something that should be relegated to the fantasy realm and science fiction.”

The Oxford Geoengineering Programme defines geoengineering as “the deliberate large-scale intervention in the Earth’s natural systems to counteract climate change.”

Balloons of Sulfur
Like a sun shield, reflective aerosols fall under the definition of solar radiation management. But unlike a sun shield, reflective aerosols aren’t modular or immediately reversible.

Make Sunsets fills balloons with SO2, releases them, and then pops them once they reach the stratosphere to release the gaseous contents. The effect, Make Sunsets claims, is similar to volcanic eruptions.
“Emissions from volcanic eruptions have been cooling the Earth for millions of years, like Mt. Pinatubo in 1991. We are simply mimicking Mother Nature. ... In 1991, Mt. Pinatubo, a stratovolcano, cooled the Earth by 0.9F or 0.5C for over a year,” it stated on its website.

So far, the group has released 49 balloons since April 2022 and claims that it has “neutralized 13,791 ton-years of warming.” It says its “clouds” of sulfur stay in the sky for between six months and three years, “depending on the altitude and latitude at which we release them.”

And here I thought the issue was aluminum. Are you worried about ice crystals?

[clusterchuck]

Nope. Not "worried" about aluminum.

As an active member of the compliant class, I see you aren't "worried" about unintended consequences scientists raised in the reference article.

I'm not "worried" about salt either. After all, "it's just salt". And, according to this totally trustworthy Politico article, this "solar modification test" is a national first.

Geoengineering Test Quietly Launches Salt Crystals into Atmosphere
A solar geoengineering experiment in San Francisco could lead to brighter clouds that reflect sunlight. The risks are numerous
APRIL 4, 2024
BY CORBIN HIAR & E&E NEWS

CLIMATEWIRE | The nation's first outdoor test to limit global warming by increasing cloud cover launched Tuesday from the deck of a decommissioned aircraft carrier in the San Francisco Bay.

The experiment, which organizers didn't widely announce to avoid public backlash, marks the acceleration of a contentious field of research known as solar radiation modification. The concept involves shooting substances such as aerosols into the sky to reflect sunlight away from the Earth.

The move led by researchers at the University of Washington has renewed questions about how to effectively and ethically study promising climate technologies that could also harm communities and ecosystems in unexpected ways. The experiment is spraying microscopic salt particles into the air, and the secrecy surrounding its timing caught even some experts off guard.

"Since this experiment was kept under wraps until the test started, we are eager to see how public engagement is being planned and who will be involved," said Shuchi Talati, the executive director of the Alliance for Just Deliberation on Solar Geoengineering, a nonprofit that seeks to include developing countries in decisions about solar modification, also known as geoengineering.

"While it complies with all current regulatory requirements, there is a clear need to reexamine what a strong regulatory framework must look like in a world where [solar radiation modification] experimentation is happening," she added.

The Coastal Atmospheric Aerosol Research and Engagement, or CAARE, project is using specially built sprayers to shoot trillions of sea salt particles into the sky in an effort to increase the density — and reflective capacity — of marine clouds. The experiment is taking place, when conditions permit, atop the USS Hornet Sea, Air & Space Museum in Alameda, California, and will run through the end of May, according to a weather modification form the team filed with federal regulators.

The project comes as global heat continues to obliterate monthly and yearly temperature records and amid growing interest in solar radiation modification from Silicon Valley funders and some environmental groups. It also follows the termination of a Harvard University experiment last month that planned to inject reflective aerosols into the stratosphere near Sweden before it was canceled after encountering opposition from Indigenous groups.

Solar radiation modification is controversial because widespread use of technologies like marine cloud brightening could alter weather patterns in unclear ways and potentially limit the productivity of fisheries and farms. It also wouldn't address the main cause of climate change — the use of fossil fuels — and could lead to a catastrophic spike in global temperatures if major geoengineering activities were discontinued before greenhouse gases decrease to manageable levels.

The University of Washington and SilverLining, a geoengineering research advocacy group involved in the CAARE project, declined interview requests. The mayor of Alameda, where the experiment is being conducted, didn't respond to emailed questions about the project.

The secrecy surrounding the landmark experiment seems to have been by design, according to The New York Times, which, along with a local newspaper, was granted exclusive access to cover the initial firing of the spray cannons.

"The idea of interfering with nature is so contentious, organizers of Tuesday's test kept the details tightly held, concerned that critics would try to stop them," the Times reported. The White House also distanced itself from the experiment, which is being conducted with the cooperation of a Smithsonian-affiliated museum.

The project team has touted its transparency, noting that visitors to the USS Hornet, which now serves as a floating museum, will be able to view the experiment.

"The world needs to rapidly advance its understanding of the effects of aerosol particles on climate,” Kelly Wanser, the executive director of SilverLining, said in a press release. "With a deep commitment to open science and a culture of humility, the University of Washington has developed an approach that integrates science with societal engagement, and can help society in essential steps toward advancing science, developing regulations, promoting equitable and effective decision-making, and building shared understanding in these areas."

Is this the part where I contribute to the thread by pointing out "current articles, DOLT"?

[Shred]

Dry adiabatic lapse rate = 3 degrees C per thousand feet lost.
Saturated adiabatic lapse rate = 1.5 degrees C per thousand feet lost.
Temperature at 35,000 feet is substantially colder than at ground level and jet exhaust cools instantly. And because modern jet engines are high bypass, the trails are fatter.

Another thing that can happen, because pressures above the wings are lower than below the wings, when it's humid, the pressure drop can cause condensation of the moisture in the air producing vortices at the tips of wings or off the flaps.

Look at the haze above the wings. That's moisture condensing.

I know lots of airline pilots through gliding.

The chemtrails conspiracy theory is nonsense.
It's a distraction from real conspiracies.

[clusterchuck]

"Moisture condensing". With the flip of a switch.

[Shred]

Again you can see the haze of humid air condensing above the wings, taking that humid air below the dew point.

Wings work, because air going over the aerofoil moves faster than air going under, this reduces pressure, provides lift and also can cause condensation of air resulting in the visibility of vortices.

I've seen the same thing happen with vortexes off the wings of sailplane gliders in winter on a humid day and off of the spoilers of F1 cars (which are upside down wings).


It's not my fault if you don't understand the laws of physics.

Why on earth would any conspiratorial organisation poison the same atmosphere it shares with the rest of us?

It wouldn't.

The Chemtrails theory is a distraction.

Whilst berks promote that nonsense, they aren't discussing things like the Ryazan incident (an actual bomb attack by the FSB), the shooting of Anna Politkovskaya (by the FSB), the poisoning of Alexander Litvinenko (by the GRU), the use of Wagner Group mercenaries to steal Donetsk and Luhansk in 2014. The illegal invasion of Ukraine (for coal oil and gas) in violation of the Budapest Memorandum, CSTO Treaty, Russia Ukraine Friendship Treaty and the UN Charter.

TLDR

[nolaxride]

I still don't see where chemtrails are a bad thing.
