Popular Science indoctrination over the years, to your sprayed skies.
When it comes to climate change, a quick fix won’t do. Science published a paper Friday from the National Center for Atmospheric Research (NCAR) which concludes that a proposed plan to inject the atmosphere with sulfate particles in order to cool the planet would actually have dire consequences.
According to the NCAR study, this geo-engineering strategy could lead to the destruction of at least one-quarter, and potentially three-quarters, of the ozone layer above the Arctic Ocean, and could delay the expected recovery of the Antarctic ozone hole by 30 to 70 years. “Our research indicates that trying to artificially cool off the planet could have perilous side effects,” says NCAR’s Simone Tilmes. “While climate change is a major threat, more research is required before society attempts global geo-engineering solutions.”
This study marks the second time the ozone layer has factored in to recent climate change research—last week, we reported on a joint NASA/NOAA/University of Colorado study linking the regeneration of ozone with increased warming in the Antarctic.
Seeding the seas or the skies to dial down the planet’s temperature
While most of the world fixates on how to reduce the amount of carbon dioxide (CO2) and other greenhouse gases we emit into the atmosphere, scientists and engineers around the world are busy working on various “geo-engineering” technologies — many of which are highly theoretical — to mitigate global warming and its effects. Many scientists oppose using new technology to fix problems created by old technology, but others view it as a quick and relatively inexpensive way to solve humankind’s most vexing environmental problem.
Geoengineering is a popular idea, for Bill Gates and just about everyone else these days. Now the Institute of Mechanical Engineers proposes that the UK adopt technologies such as carbon-capturing artificial trees, biofuel algae tanks on rooftops, and coating surfaces in reflective materials to cut down on heating from the sun’s rays.
Plenty of experts also still want to tread lightly when it comes to geoengineering, for fear of unintended consequences on a global scale. The White House science advisor and the U.S. National Academy of Sciences gingerly examined the topic this summer and concluded that caution is warranted.
June 18,2009- Geoengineering; Are Weather Machines Really the Answer??
Now that we know definitively that humans can alter Earth’s climate, some scientists have begun investigating ways to deliberately change the weather to offset the negative impact of a century of inadvertent human generated climate change.
The name for that deliberate, targeted climate change is geoengineering, and its on the mind of everyone from the National Academy of Sciences to Barack Obama’s science adviser.
On Monday, the National Academy of Sciences held a workshop on geoengineering, following an interview where White House Science Adviser John Holdren recommended increased research into the subject. While the scientists at the workshop agreed that it was possible, there was disagreement about when to start testing the ideas, and whether or not the cure might be worse than the problem.
According to National Public Radio, one of the more popular ideas involves seeding the sky with sulfur particulate to reflect the rays of the sun and cool the Earth.
No one is sure if any of these plans will work, if geoengineering is even legal, or what unintended nightmare consequences may result from wholesale disruption of the Earth’s carefully balanced ecosystem.
Billionaire Bill Gates has patented the idea to halt hurricanes by decreasing the surface temperature of the ocean.
The patent calls for a large fleet of specially equipped ships which would mix warm water from the ocean surface with colder water down below, according to five new patents that include Microsoft’s chairman as a co-inventor. That could then reduce or perhaps eliminate the heat-driven condensation which hurricanes feed upon, thus significantly reducing their intensity.
This represents just the latest in a long line of geoengineering proposals aimed at taming Mother Nature, whether aimed at climate change or hurricanes. Even the prestigious National Academy of Sciences held a workshop in June on geoengineering, although that ended with disagreements on whether the cure might be worse than the problem.
We previously looked at other plans regarding hurricanes, such as sending supersonic jets slicing into the eye of the giant storms. But for now, it’s likely that coastal cities should at least invest in more grounded ideas to become hurricane-proof.
Bill Gates has already proven his interest in geoengineering schemes with his earlier co-patent filing for reducing the intensity of killer hurricanes. So perhaps we’re not too surprised that Science Insider has dug up the Microsoft chairman’s past projects on altering the Earth’s climate, ranging from filtering carbon dioxide to reflecting sunlight via brighter clouds.
The billionaire founder of the PC has apparently quietly funneled $4.5 million of his own money to geoengineering research since 2007. Two researchers who have served as energy and climate advisers for Gates — Ken Caldeira of the Carnegie Institution for Science in Palo Alto, California and physicist David Keith of the University of Calgary in Canada — have had the duty of dispensing the money as they saw fit. Naturally, scientists and students working for Keith and Caldeira have benefited from some of the philanthropic money. But geoengineering conferences held in Cambridge, Massachusetts and Edinburgh, Scotland have also received backing from Gates.
Of all of C. Montgomery Burns’s nefarious dealings on The Simpsons, perhaps none sticks in the public consciousness like the time he attempted to use a massive shade to block out the sun (most notably because doing so led to his being shot by a vigilante baby and an uncharacteristic two-episode event). But the U.N. may soon put all such plans to blot out the sun – villainous or otherwise – on hold.
The U.N. convention could choose to take up this topic – no joke – during the tenth meeting of the Conference of the Parties to the Convention on Biological Diversity going on until the end of this month in Nagoya, Japan. It might sound a bit sci-fi, but some in the scientific community have advocated reducing the amount of sunlight reaching earth to slow the effects of global warming.
Regardless, it appears the U.N. aims to look into banning sunshades or at least limit research into them
It only takes one rained-out Little League game to make a sports lover resent Mother Nature. Now some of today’s scientists and other bigwigs have taken it upon themselves to say: “no more.” Not content to stand idly by and let something as mundane as climate dictate the success of our sports games, they have instead turned to geoengineering – intentional manipulation of the Earth’s environment – to fight back.
Qatari engineers recently announced a project to develop solar-powered artificial clouds to shade the 2022 World Cup from the country’s unforgiving summer sun. One remotely steerable cloud comes with a hefty price tag – $500,000 – just to cool the field by 10 degrees.
Amid concerns that the Qatari summer heat could be dangerous for players and attendees of the 2022 World Cup, researchers at Qatar University have developed artificial clouds to shade the stadiums and training grounds. After it became clear that there were no plans to move the tournament to the winter, scientists developed them to battle summer temperatures of up to 120 degrees Fahrenheit. Using the clouds has the potential to reduce the temperature on the field by 10 degrees. The clouds, which cost $500,000 each, are made of lightweight carbon and held aloft with helium. Solar-powered engines move them via remote control.
2011-Most People Are In Favor Of Wild Geoengineering Projects
A majority of people in Canada, the United Kingdom and the United States support studying ways to reflect sunlight as a method to cool the planet, according to a new study. Researchers at Harvard and two Canadian universities say nearly three-quarters of survey respondents approved research into geoengineering.
The survey, which was just published although it was conducted last year, focused on solar radiation management, a type of geoengineering that seeks to increase the Earth’s albedo by creating clouds or through other means. Support for the technique was spread across the political spectrum, the researchers say. But people who defined themselves as politically conservative expressed the strongest opposition to geoengineering.
Only eight percent of people were able to correctly define what geoengineering means, with about 45 percent able to define the alternative term “climate engineering,” which is apparently easier to figure out.
The survey findings come at an interesting time, because a solar radiation management experiment that was supposed to start this month in the UK was just delayed by 6 months to address concerns by critics.
Even if they can be a major disaster for people nearby them, volcanoes do one good thing: helping to cool the planet by sending sun-reflecting chemicals into the stratosphere. Now two Harvard engineers are trying to replicate the better part of the volcanic process on a small scale by spraying thousands of tons of sulfate aerosols into the atmosphere above New Mexico.
Within a year, the researchers, David Keith (who manages a multimillion dollar geoengineering research fund from Bill Gates) and James Anderson, will release the chemicals from a balloon 80,000 feet above Fort Sumner, then measure the effects on the ozone’s chemistry. (To answer the big question: no, this can’t be pulled off in a lab.) This will be a test, not a full-on attempt to stop climate change, the researchers say, and it won’t have any major effects on the environment.
Nonetheless, geoengineering strategies like this are controversial, to say the least.
Hurricanes form in warm tropical waters, drawing strength from the heat of the ocean surface — that’s why they are expected to worsen as sea surface temperatures increase. But if we could cool them off, they may chill out and decrease in strength. Cloud seeding the areas in front of their path might be a way to do this, a new study says.
The idea is to target marine stratocumulus clouds, which cover about a fourth of the world’s oceans. Reflecting more light away from the sea surface (Solar Radiation Management) would theoretically prevent it from getting as warm. “Then there will be less energy to feed the hurricanes,” said Alan Gadian of the University of Leeds.
In this concept, a fleet of drones at or near the surface could spray sprinkles of seawater droplets, some of which would rise into the atmosphere.
The increased droplet concentration would make the clouds thicker, causing them to last longer and reflect more sunlight, the Leeds scientists say. By the way, this is the same basic technique Beijing officials used to create rain during the 2008 Olympics.

Everything you need to know about geoengineering
Scientists may finally put some of the basic principles to the test in 2018
Whether we intend to or not, humans are altering the climate, and recent cuts to environmental science budgets suggest we shouldn’t expect America to dramatically curb its carbon emissions anytime soon. But while federal scientists are avoiding terms like “climate change” in their budget proposals, one word has been resurfacing in the media: geoengineering.
Geoengineering could attempt to bring down the global fever in two ways. The first is by capturing carbon, either by planting forests that absorb carbon for photosynthesis and then store it as food, or via human-made technologies that pull carbon out of the air and store it underground. But scientists haven’t perfected those technologies yet, and they wouldn’t be as fast-acting as the second method, which would reduce heat by reflecting sunlight back into space. Some scientists think this could be done by seeding the atmosphere with shiny particles, extra clouds, or space mirrors.
After years of watching volcanos go through the motions, some researchers are looking into whether they can use that same method to help cool down the planet—an idea known as solar geoengineering.
For their recent study, Jones and his colleagues looked at what would happen if sulfuric aerosols were injected in just the Southern or Northern Hemisphere.
Hollywood’s latest disaster flick, “Geostorm,” is premised on the idea that humans have figured out how to control the Earth’s climate. A powerful satellite-based technology allows users to fine-tune the weather, overcoming the ravages of climate change. Everyone, everywhere can quite literally “have a nice day,”
Geoengineering, also called climate engineering, is a set of emerging technologies that could potentially offset some of the consequences of climate change. Some scientists are taking it seriously, considering geoengineering among the range of approaches for managing the risks of climate change
These innovations are often lumped into two categories. Carbon dioxide removal (or negative emissions) technologies set out to actively remove greenhouse gases from the atmosphere.
In contrast, solar radiation management (or solar geoengineering) aims to reduce how much sunlight reaches the Earth.
