The plan sounds like science fiction — but could be fact within a decade; every day more than 800 giant aircraft would lift millions of tonnes of chalk dust to a height of 12 miles above the Earth’s surface and then sprinkle the lot high around the stratosphere.
In theory, the airborne dust would create a gigantic sunshade, reflecting some of the Sun’s rays and heat back into space, dimming those that get through and so protecting Earth from the worsening ravages of climate warming.
This is not the crackpot plan of a garden-shed inventor. The project is being funded by billionaire and Microsoft founder Bill Gates and pioneered by scientists at Harvard University.
Indeed, the plans are so well advanced that the initial ‘sky-clouding’ experiments were meant to have begun months ago.
This initial $3 million test, known as Stratospheric Controlled Perturbation Experiment (SCoPEx) would use a high-altitude scientific balloon to raise around 2kg of calcium carbonate dust — the size of a bag of flour — into the atmosphere 12 miles above the desert of New Mexico.
This would seed a tube-shaped area of sky half a mile long and 100 yards in diameter. For the ensuing 24 hours, the balloon would be steered by propellers back through this artificial cloud, its onboard sensors monitoring both the dust’s sun-reflecting abilities and its effects on the thin surrounding air.
SCoPEx is, however, on hold, amid fears that it could trigger a disastrous series of chain reactions, creating climate havoc in the form of serious droughts and hurricanes, and bring death to millions of people around the world.
One of the Harvard team’s directors, Lizzie Burns, admits: ‘Our idea is terrifying… But so is climate change.’ An advisory panel of independent experts is to assess all the possible risks associated with it.
So where did the idea for such a mind-boggling scheme come from?
The inspiration was in part spawned by a natural disaster. When the volcano Mount Pinatubo in the Philippines exploded in 1991, it killed more than 700 people and left more than 200,000 homeless.
But it also gave scientists the chance to monitor the consequences of a vast chemical cloud in the stratosphere.
The volcano disgorged 20 million tonnes of sulphur dioxide high above the planet, where it formed droplets of sulphuric acid that floated around the globe for more than a year. These droplets acted like tiny mirrors to reflect sunlight.
As a result, global temperatures were reduced by 0.5c for around a year and a half.
This gave impetus to a idea of a dream ‘fix’ of global warming — and has been the subject of at least 100 academic papers.
But creating what amounts to a gigantic sunshade for the Earth may come at a high price, posing even greater risks than climate change itself.
One fear is that spreading dust into the stratosphere may damage the ozone layer that protects us from hazardous ultraviolet radiation which can damage human DNA and cause cancers.
Climatologists are also concerned that such tinkering could unintentionally disrupt the circulation of ocean currents that regulate our weather.
This itself could unleash a global outbreak of extreme climatic events that might devastate farmland, wipe out entire species and foster disease epidemics.
The potential for disaster does not even end there. Trying to dim the Sun’s rays would likely create climate winners and losers.+7

Scientists may be able to set the perfect climatic conditions for farmers in America’s vast Midwest, but at the same time this setting might wreak drought havoc across Africa.
For it is not possible to change the temperature in one part of the world and not disturb the rest. Everything in the world’s climate is interconnected.
Furthermore, any change in global average temperature would in turn change the way in which heat is distributed around the globe, with some places warming more than others.
This, in turn, would affect rain levels. Heat drives the water cycle — in which water evaporates, forms clouds and drops as rain. Any heat alteration would cause an accompanying shift in rainfall patterns. But how and where exactly?
There is no way of predicting how the world’s long-term weather may respond to having a gigantic chemical sunshade plonked on top of it.
As one of the world’s leading climate experts Janos Pasztor — who advised at the UN’s Paris climate agreement and now works for New York’s highly respected Carnegie Climate Governance Initiative — warns: ‘If you make use of this technology and do it badly or ungoverned, then you can have different kinds of global risks created that can have equal, if not even bigger, challenges to global society than climate change.’
The technology may even spark terrible wars. For tinkering with our climate could send sky-high the potential for international suspicion and armed conflict.
Say, for example, the Chinese government — which already has been experimenting with climate-altering technology — used its burgeoning space-age scientific know-how to try to dust the stratosphere to protect its own agricultural yields.
Then two years later the monsoons fail in neighbouring Asian giant India, causing widespread starvation and disease. Even if the Chinese move had not actually caused the monsoons to fail, billions would blame them.
There is a further peril. The technology involved is seductively cheap, perhaps less than $10 billion a year. This means that an individual nation could use it for their own ends — perhaps as a weapon of war or blackmail.
What’s to stop a nation such as Russia interfering with our weather in the same way it has interfered with elections and social media opinions?
Nevertheless, Harvard scientists maintain that they can manage their brainchild safely.
For example, one of the SCoPEx team’s leaders, David Keith, a professor of applied physics, recently reported that by evenly seeding the entire global atmosphere with low levels of reflective dust, there should be a far lower risk of unexpected problems than is feared.
Professor Keith has also suggested that the world’s richer nations should club together to create a pooled global insurance fund to compensate poorer countries for any damage unintentionally caused by their sun-shield experimentation.
Critics point out that the promise of a stratospheric sunshade could encourage politicians and industrialists to decide that there is no need to do the hard, unpopular and expensive work of reducing greenhouse gas emissions.
Mike Hulme, a Cambridge University professor of human geography and former scientist on the Intergovernmental Panel on Climate Change, says we could end up instead relying massively on technology to compensate for climate problems that our industries are causing.
He calls this spiralling problem ‘temperature debt’, because it is like amassing credit-card debts that can never be paid off. ‘It is a massive gamble,’ Professor Hulme warns. ‘Far better not to build up this debt in the first place.’
Even greater questions arise. How do you switch such a global cooling system off? And what unforeseen consequences would arise if you suddenly did so.

Analysis
This comes from the man who claims to have revolutionized personal computing with his own programming skills, when all he did was to buy the software from a startup company and branded it Microsoft.
Now, he thinks he has a novel idea of blanketing the atmosphere with tons of dust to cover the sun and stop global warming. Wait!
Didn’t he advocate for Innovating to Zero, as in zero population to stop global warming because he believes that the root cause of the increasing heat is not the sun, but the fossil fuel consumption of an ever increasing number of people on this planet?
So, which is it really: carbon emissions, or the sun itself, that is causing the rise in global temperature?
It seems that in their quest to accelerate their technocratic dictatorship, owing in part to the great successes of their ongoing COVID-19 plandemic, Bill Gates and his ilk couldn’t wait and contain their excitement of having the entire population’s survival at their fingertips, that they have to contradict their decades-old mantra that carbon emissions are what’s causing global warming.
The simple truth is of course the global rise and fall of temperature is caused by the sun itself and it’s cyclical.
Another very important fact is the positive effect of the increase in sun’s energy, which is the heightened mental activity that spurs revolution worldwide. This probably is what they’re trying to prevent from happening.
We have yet to stop the chemtrailing of our skies, and now this atmospheric dusting?
Maybe it’s time for Bill Gates to bite the dust himself.
