Bill Gates wants to spray millions of tonnes of chalk into the stratosphere to reflect sunlight and slow global warming

The test would use a high-altitude scientific balloon (pictured) to raise around 2kg of calcium carbonate dust — the size of a bag of flour — into the atmosphere 12 miles above the surface


The first test of a project backed to spray millions of tonnes of chalk into the stratosphere, in an attempt to 'dim the sun' and cool the Earth, could happen in June.

Harvard University experts will test the system by sending a large balloon 12 miles above the Swedish town of Kiruna and have it drop 2kg of chalk dust into the stratosphere.

The aim of the estimated $3 million mission, backed by billionaire Bill Gates, is to have the chalk deflect a portion of the sun's radiation, stop it from hitting the surface, and cool the planet.

The idea has been heavily criticised since its inception, with project director Frank Keutsch even calling the need for this scale of geo-engineering 'terrifying'.

And experts have warned that the unusual technique could be disastrous for weather systems in ways nobody can predict.

Backed by a range of private donors including Gates, the test mission is launching from Sweden as they could offer a launch by the end of this summer. 

The test balloon will lift 600kg of scientific equipment 12 miles above the surface of the Arctic town and if it all goes well, about 2kg of dust will be released. 

This will then create a dust plume several kilometres in length - not large enough to have any effect on the intensity of the sun's rays hitting the Earth. 

During that first test the team would gather information on how particles of dust react with the air.

Bill Gates Wants to 'Cover the Sun' to Help Counter Global Warming

Bill Gates Wants to 'Cover the Sun' to Help Counter Global Warming

Entrepreneur  January 22, 2021

"You can't cover the sun with a finger", but maybe with science and technology yes. According to Forbes , Bill Gates is funding a project that would dim sunlight in order to "cool" the Earth.

The research called " Stratospheric Controlled Disturbance Experiment " (SCoPEx for its acronym in English) is carried out by scientists from Harvard University and has the purpose of achieving that the sunlight is reflected outside the atmosphere of our planet. 

This solution would be achieved by spraying tons of non-toxic calcium carbonate (CaCO3) into the atmosphere. "SCoPEx is a scientific experiment to advance the understanding of stratospheric aerosols that could be relevant for solar geoengineering," the project page reads.

The project will begin to carry out tests that so far consist of releasing a balloon with scientific equipment, which will not spray CaCO3 but will function as a test of maneuver and to explore communications and operating systems.

“We plan to use a high-altitude balloon to lift an instrument package approximately 20 km into the atmosphere. Once in place, a very small amount of material (100g 2 kg) will be released to create a disturbed air mass approximately one kilometer long and one hundred meters in diameter. Then we will use the same balloon to measure the resulting changes in the disturbed air mass, including changes in aerosol density, atmospheric chemistry and light scattering, ”they explain.

Bill Gates always seems to know when it’s time to go

Computer World  
Bill Gates resigned from Microsoft’s board of directors last week, pretty much ending his official ties to the company he co-founded. He says he’s still available as a technology adviser to CEO Satya Nadella and other Microsoft leaders, but otherwise he’s devoting himself completely to his other pursuits, like philanthropy.
Gates and the company he started very nearly 45 years ago with Paul Allen transformed the computing landscape. Throughout the period of Microsoft’s early growth and maturation, Gates was at the helm as CEO, demonstrating business leadership and competitiveness that, even more than technology, were keys to the company’s success.
The competitiveness eventually led to Microsoft’s antitrust issues. The technology world was changing (I’ll go through some of that history in a bit), and the leader who had made Microsoft a tech giant was perhaps no longer tuned in to the changes as he once had been. That happens a lot with founders. What rarely happens is that the founder sees the writing on the wall and takes a step back. But Gates did. He resigned as CEO, staying on as chairman of the board.
Not everything Gates did was brilliant. By the time the internet had become a force in the tech world, Gates and Microsoft had made a series of missteps that almost made the company irrelevant. And in resigning as CEO, Gates left Steve Ballmer in charge. Ballmer clearly had earned the right to lead Microsoft as CEO, but he wasn’t right for the job, and Gates eventually had to remove him. The men had always been close, and it couldn’t have been easy to do it, but he did.

Founder power

This is the third step back from Microsoft that Gates has taken. He dropped his day-to-day duties as CEO in 2006, and gave up ultimate oversight as chairman of the board in 2014. Now he has relinquished his seat on the board.
This is actually a remarkable record. Founders have extraordinary power at a company, and they often don’t know when to step down, sometimes doing the company so much harm in their later years that the firm doesn’t recover. Even if they step away from day-to-day activity, they often step in and exert their influence at critical times, undermining the sitting CEO and setting the company up for failure. As chairman, Gates seemed to have refrained from that sort of thing, until the day came when Ballmer had to go.

Donald Trump thinks that the way to stop extremists is to shut down parts of the internet


Donald Trump

By8 DEC 2015
United States Presidential candidate Donald Trump has called on Bill Gates to shut down parts of the internet, to prevent radical extremists from spreading their ideas online.
During a campaign rally on Monday, Mr Trump suggested that closing the internet in some unspecified places will prevent people from connecting with and joining ISIS.
"We are losing a lot of people to the internet. We have to do something. We have to go see Bill Gates and a lot of different people that really understand what's happening," he said.
"We have to talk to them [about], maybe in certain areas, closing that internet up in some way."
He added: "Some people will say, 'freedom of speech, freedom of speech'. These are foolish people. We have a lot of foolish people."
Bill Gates , the American business magnate and founder of Microsoft, is yet to reply to Mr Trump's call to action. However, since his interests lie more in philanthropy these days, he is unlikely to have an immediate solution.
As part of the same speech, Mr Trump called for a " total and complete shutdown " of all Muslims entering the United States.
The billionaire, already accused of a slew of racist comments during his campaign to be Republican candidate for President, claimed 51% of Muslims want to govern the US with Sharia law.
He also later picked a fight with Amazon chief executive Jeff Bezos on twitter, accusing the company of not paying "fair taxes". Trump suggested that if Amazon did so, its "stock would crumble like a paper bag".     Mirror

Bill Gates, Mark Zuckerberg, Richard Branson, Jeff Bezos, and pretty much every other crazy rich tech team up to take on climate change

President Obama joined leaders from 150 nations on Monday in pledging action against climate change

President Obama joined leaders from 150 nations on Monday in pledging action against climate change, kicking off a historic two-week gathering that Obama called a “turning point” in the battle against one of humanity’s gravest threats.
Heads of state from industrial powers and tiny island nations assembled in a heavily guarded conference center north of Paris, where negotiators hope to forge a treaty to dramatically reduce emissions of greenhouse-gas pollution blamed for warming the planet.
Obama, speaking a few miles from the site of the Nov. 13 terrorist attack in the French capital, called for urgent action against a challenge that he suggested was greater even than the fight against terrorism.
“The growing threat of climate change could define the contours of this century more dramatically than any other,” Obama said in a speech at the Le Bourget conference center in Paris’s industrial outskirts. “What should give us hope that this is a turning point, that this is the moment we finally determined we would save our planet.”
Obama, who has staked his legacy on the fight against climate change, struck an ominous tone in describing the ravages of a warming planet, declaring that “no nation large or small, wealthy or poor, is immune.” He urged the leaders to take action even if the benefits were not evident for generations.

Citing Martin Luther King Jr., he warned that “there is such a thing as being too late.”
The remarks came during a day of ceremonial fanfare as well as substantive progress in marshaling resources to speed the shift to cleaner energy. U.S. officials formally announced the formation of a 20-nation initiative to spur funding on energy research, in tandem with a similar undertaking led by Microsoft co-founder Bill Gates and 27 of the world’s wealthiest private investors.
But there were also signs of discord as negotiators prepared to haggle over details of a complex treaty that requires all nations — even the poorest ones — to make a contribution to cutting greeenhouse-gas pollution. Some developing countries have insisted on compensation for economic and environmental damage stemming from decades of industrial emissions that came mostly from Western industrial powers.
French Foreign Minister Laurent Fabius opened the conference by calling on all governments to back an ambitious treaty.
“The stakes are too high and the menace of climate change is too great for us to be content with a minimalistic agreement,” he said.
Obama has already aligned most of the world’s largest greenhouse gas emitters behind substantial cuts in greenhouse gas emissions, but over the next dozen days international climate negotiators must still nail down the details of an agreement that would strengthen existing commitments and introduce a way for countries to review and expand their commitments in the near future.
The negotiations have been slowed by delegates from developing countries who believe that, for all of Obama’s efforts, the United States should do even more to help them grapple with the effects of climate change and lower global emissions.
Obama said that “the United States not only recognizes our role in creating this problem, we embrace our responsibility to do something about it.” But he stressed that all nations must act “right now.”
More than two weeks after terrorist attacks rocked this city and shocked the world, Obama described the gathering of world leaders here as “an act of defiance” and asked: “What greater rejection of those who would tear down our world than marshaling our best efforts to save it?”
With so many world leaders present, the summit also opened chances for top-level dialogue on other fronts.
Sideline talks included a meeting between Obama and Russian President Vladi­mir Putin to discuss Syria’s nearly five-year civil war and peace efforts in Ukraine between the Western-supported government and Moscow-backed rebels.
The two leaders agreed to continue talks among global stakeholders that began this fall in Vienna to forge a political solution to the fighting in Syria. But the two sides remain far apart on some key issues, and no clear progress appeared to have been made in Paris.
Russia says its military intervention in Syria seeks to cripple the Islamic State — a mutual enemy of Washington and its allies. But Moscow has heavily targeted rebel factions seeking to topple Syrian President Bashar al-Assad, a key Russian partner. In Paris, Obama repeated U.S. demands that Assad must eventually step down as part of any political transition.
Obama kicked off his day meeting with Chinese President Xi Jinping, hailing their mutual work on climate change but urging greater Chinese cooperation on cybercrime and “maritime” issues that include China’s military construction on disputed reefs in the South China Sea.
Putting China first on the schedule was an indication of China’s central role on global issues such as climate change.
It was just a year ago that Obama and Xi vowed to set definite limits on greenhouse gas emissions, laying the foundation for other countries to follow suit. On Monday, Obama said: “Our leadership on this issue has been absolutely vital.”
Other highlights included a meeting with Indian Prime Minister Narendra Modi, whose government has been pressing for more financing and technology transfer. U.S. officials expressed frustration that Modi had not pledged to do more to avoid sharp increases in coal-fired electricity to help the 240 million Indians who lack electricity. They hoped to make progress in the coming days.
Obama also attended the formal unveiling of an initiative to boost research and development spending on new technologies, led by Gates. The Microsoft founder, in an interview with The Washington Post, warned that the climate threat is too serious to allow technology to evolve at the usual slow pace.
“Historically, it takes over 50 years before you have a substantial shift in energy generation, but we need to do it more quickly,” Gates said. “We need to move faster than the energy sector ever has.”
Obama expressed belief that a breakthrough was needed in addition to current technologies, something some critics say is too optimistic. “We don’t know exactly what’s going to work best but we know if we put our best minds behind it and put our dollars behind it we’ll discover what works,” Obama said.
Some countries believe solutions lie closer. A group of countries — France, Canada, Chile, Ethiopia, Germany and Mexico — proposed putting a worldwide price on carbon to discourage the use of carbon intensive fuels, such as coal.
The chances of getting such a proposal through the Republican-controlled Congress, however, are remote. It is also unclear whether Congress will provide the additional research dollars Obama pledged as part of the Gates “innovation” initiative.
The summit will also feature a goal, heavily promoted by India and including 121 countries, of a massive investment in solar power in countries with the greatest amounts of sunlight.
“We have broken the old arguments for inaction,” Obama said at the plenary session Monday. “We have proved that strong economic growth and stable investment no longer have to conflict with one another.”
Obama is one of about 150 world leaders at the Paris summit — formally known as the 21st Conference of Participants. Those leaders also delivered speeches.
“A political moment like this may not come again,” said U.N. Secretary General Ban Ki-moon. “We have never faced such a test. But neither have we encountered such great opportunity.”
In the wake of terrorist attacks that left 130 dead, the conference, taking place in a center located at an old airport in Le Bourget, has become a major security headache, and traffic has been blocked in Paris until Tuesday.
After arriving in Paris on Sunday, Obama’s motorcade glided along the Seine through largely deserted streets before stopping in front of Le Bataclan, the concert hall where scores of people were killed in the terrorist attacks.
Flanked by French President François Hollande and Paris Mayor Anne Hidalgo, Obama placed a white rose on the street in front of the concert hall, making a small addition to the mound of flowers and candles there. After standing for a minute of silence with his hands folded before him, Obama walked away, briefly placing a hand on the shoulders of Hollande and Hidalgo.
The United States announced that it will contribute $51.2 million to a $248 million Least Developed Countries Fund to help the world’s poorest countries adapt to climate change. Germany is the largest of 11 donors to the fund.
“We know the truth — that many nations have contributed little to climate change but will be the first to feel its most destructive effects,” Obama said.
But U.S. officials said they would resist calls by many small island states and other countries vulnerable to climate-change effects that developed nations pay reparations or damages because of their historic emissions. Those nations also favor setting a goal of limiting climate change to 1.5 degrees Celsius instead of 2 degrees. Obama will meet with leaders of island nations Tuesday.
Other countries used the conference to announce new details. Norway, Germany and Britain said they would provide $1 billion a year until 2020 in payments for verified emissions reductions from forests and land use in other countries.
