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.

Sunlight and Vitamin D: They’re Not the Same Thing

Sunlight and Vitamin D: They’re Not the Same Thing

Westonaprice   April 20, 2020

ARTICLE SUMMARY
• Sulfate synthesis in the skin captures the sun’s energy. Adequate sunlight exposure to both the skin and the eyes is vital to our long-term health.
• Among other functions, sulfate supports blood vessel health, the body’s electrical supply and the delivery system for important molecules such as cholesterol, vitamin D, dopamine and melatonin.
• Evidence indicates that sunlight protects against cancer, heart disease, hypertension and bone fractures.
• The benefits of sunlight exposure are about much more than vitamin D.

• Many studies show that vitamin D supplementation cannot reproduce sunlight’s health benefits. Moreover, excessive vitamin D supplementation can aggravate systemic sulfate deficiency, which will drive calcium buildup in the arteries.

• Both sunscreen and glyphosate interfere with synthesis and production of melanin—the body’s natural mechanism of sun protection. Aluminum in sunscreen disrupts sulfate synthesis. These disruptions may explain why melanoma prevalence has steadily risen in tandem with the increased use of higher sun-protection-factor sunscreens over the past two decades.

 

We have been brainwashed into believing that the sun is toxic, whereas in fact it is life-giving. I am a great fan of sunlight exposure to both the skin and the eyes. The sun has been a resource for Planet Earth since the beginning of time, and biological organisms evolved with a constant supply of energy they could count on every day with the rising sun. Plants use the energy of sunlight to convert inorganic carbon into organic matter, with the help of chlorophyll. Why would animals ignore such an obvious energy source? Just as plants need sun­light to grow, sunlight plays an essential role in energizing animals, including humans.

I believe that the mechanism with which we safely exploit the sun’s energy is through the oxidation of sulfur to sulfate, with the help of choles­terol. This reaction takes place in the skin—catalyzed by sunlight—and it is vital to our long-term health.

PROTECTIVE SUNLIGHT

People who live in places with little sun have statistically higher risk for many chronic conditions, including multiple sclerosis, diabe­tes, cardiovascular disease, autism, Alzheimer’s disease and age-related macular degeneration.1 On the other hand, a great deal of epidemio­logical evidence suggests that sunlight exposure protects from many different types of cancer. Ultraviolet (UV) radiation is recommended in treating different skin conditions, including pso­riasis, eczema, jaundice and acne. Sunlight may also be beneficial in healing various autoim­mune diseases, including rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease and thyroiditis.

Yet chances are that your dermatologist has told you to “stay out of the sun and take a vitamin D supplement every day.” For some, this has seemed like good advice because we have been taught to believe that the sun causes skin cancer and that the only reason to get out in the sunlight at all is to boost vitamin D levels through its UV-stimulated synthesis in the skin. Driven by the belief that the benefits of sunlight exposure are mainly due to vitamin D synthesis, the natural conclusion is that vitamin D supple­ments would achieve the same goal.

The story is not that simple, however. When placebo-controlled studies are conducted on vi­tamin D supplementation, they usually produce disappointing results. I believe the reason is that sunlight exposure is about a whole lot more than vitamin D synthesis in the skin. In a paper published in 2016, Richard Weller wrote: “A substantial body of evidence shows that sunlight has health benefits and that these are independent of vitamin D and thus cannot be reproduced by oral supplementation.”2

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.

Sunlight destroys virus quickly

Harnessing the Entire Spectrum of Sunlight to Make Solar Energy ...

Yahoo News April 2020

Preliminary results from government lab experiments show that the coronavirus does not survive long in high temperatures and high humidity, and is quickly destroyed by sunlight, providing evidence from controlled tests of what scientists believed — but had not yet proved — to be true.

A briefing on the preliminary results, marked for official use only and obtained by Yahoo News, offers hope that summertime may offer conditions less hospitable for the virus, though experts caution it will by no means eliminate, or even necessarily decrease, new cases of COVID-19, the disease caused by the coronavirus. The results, however, do add an important piece of knowledge that the White House's science advisers have been seeking as they scramble to respond to the spreading pandemic.

The study found that the risk of "transmission from surfaces outdoors is lower during daylight" and under higher temperature and humidity conditions. "Sunlight destroys the virus quickly," reads the briefing.

The growing evidence on vitamin D and Covid

Spectator 18 May 2020
The argument that vitamin D deficiency may contribute to more severe cases of Covid is gaining ground. It is now reaching the point where it is surprising that we are not hearing from leading medical officials and politicians that people should consider taking supplements to ensure they have sufficient vitamin D.

This is not the same as arguing that vitamin D is a magic bullet that will cure the disease. Vitamins are not medication, the taking of which will have positive effects on everybody. They are top-ups: things that hurt you when you don't have enough of them in your system but do no extra good when you have enough. Indeed, with many vitamins, including D, taking too much can be toxic.

However, it is true that many people are deficient in vitamin D, especially at the end of winter. That is because, uniquely, vitamin D is a substance manufactured by ultraviolet light falling on your skin. You can get some from fish and other foods, but not usually enough. So most people's vitamin D levels fall to a low point in February or March when the sun has been weak and its UV output especially so. Public health bodies have long advised people to supplement vitamin D in winter anyway.

The level falls especially low in people who stay indoors a lot, including the elderly, and in those who have darker skin. Whereas the safe level of vitamin D is generally agreed to be above 10 nanograms per millilitre, one recent study of South Asians living in Manchester found average levels of 5.8 in winter and 9 in summer: too low at all times of the year. Darker skin reduces the impact of sunlight; so does the cultural habit of veiling; and so does a reluctance among some Muslims to take supplements that might have pork-derived gelatin in them.

A bit of sun might help diversify the bugs in your gut

NBC   Oct. 24, 2019
A bit of sun might help diversify the bugs in your gut, a study published Thursday suggests.
Brief exposure to ultraviolet rays not only bumps up vitamin D levels, but could also lead to a more varied collection of gut bacteria, according to the Frontiers in Microbiology study.
On the surface, sunlight and gut microbes seem to have nothing in common — after all, your gut bacteria are unlikely to find themselves catching some rays.

Sunshine Is The Ultimate Protection Against Eczema

Prevent Disease  NOVEMBER 1, 2018
Babies who spend more time in the sun are less likely to develop eczema, but it may not be because it boosts their vitamin D levels as previously thought says a new study in Journal of Allergy and Clinical Immunology.

Very common vitamin deficiency linked to higher levels of depression


Vitamin Deficiency
Spring 
Almost half of young women have insufficient vitamin D levels, which is linked to depression.
The new study also found that over one-third of young women had signs of clinical depression.
Dr David Kerr, the psychologist who led the study, said:
“Depression has multiple, powerful causes and if vitamin D is part of the picture, it is just a small part.
But given how many people are affected by depression, any little inroad we can find could have an important impact on public health.”
While many suspect a link between the vitamin deficiency and depression, studies have not often confirmed it.
Dr Kerr continued:
“The new study was prompted in part because there is a widely held belief that vitamin D and depression are connected, but there is not actually much scientific research out there to support the belief.
I think people hear that vitamin D and depression can change with the seasons, so it is natural for them to assume the two are connected.”

Spending too much time in dimly lit rooms may actually change the brain's structure



Spending too much time in dimly lit rooms and offices may actually change the brain's structure and hurt one's ability to remember and learn, indicates groundbreaking research by Michigan State University neuroscientists.

All life evolved with the electromagnetic frequencies from the sun and the earth, and these frequencies are considered essential to all life. Life itself synchronizes and harmonizes with these frequencies. But what happens when these frequencies are disrupted by modern technology?

The researchers studied the brains of Nile grass rats (which, like humans, are diurnal and sleep at night) after exposing them to dim and bright light for four weeks. The rodents exposed to dim light lost about 30 percent of capacity in the hippocampus, a critical brain region for learning and memory, and performed poorly on a spatial task they had trained on previously.

The rats exposed to bright light, on the other hand, showed significant improvement on the spatial task. Further, when the rodents that had been exposed to dim light were then exposed to bright light for four weeks (after a month-long break), their brain capacity -- and performance on the task -- recovered fully.

The study, funded by the National Institutes of Health, is the first to show that changes in environmental light, in a range normally experienced by humans, leads to structural changes in the brain. Americans, on average, spend about 90 percent of their time indoors, according to the Environmental Protection Agency.

Are you deficient in vitamin D?

Image result for Dermatologists Hate the Sun
By Dr. Mark Sircus, Ac., OMD April 20, 2017
Are you deficient in vitamin D? For most people today the answer is yes, you are not getting enough vitamin D. If you are listening to your dermatologist, you definitely are because he or she has a problem with the sun.
You do not want to be like them—you want to love the sun. More than three-fourths of people with a variety of cancers have low levels of vitamin D, and the lowest levels are associated with more advanced cancers so you really want to make friends with the sun.
A study has found that the number of people being diagnosed with vitamin D deficiency has tripled from 2008 to 2010 in the United States. Some researchers believe that up to 75% of the United States population may not be getting enough vitamin D (levels below 30 ng/ml).[1]
Essential for brain health, a strong immune system and weight management, Vitamin D3 is a fat-soluble vitamin that your body can get through sun exposure, food or supplements. However, nearly 50 percent of the population worldwide suffers from vitamin D3 deficiency.
Much of this problem is create by dermatologists. God forbid one of their patients steps outside on a sunny or a cloudy day, they had better cover their skin with sunscreen and do it right so the minimum amount of sunrays actually touches the skin. Did you know that 90% of Alzheimer’s disease patients have low levels of vitamin D?

Respect the Sun

Dermatologists are not the only ones that hate the sun but at least they do not pretend it does not exist like global warming fake scientists and governmental officials do. It is very important that we get into a correct relationship with the sun because without it we would die. The sun gives life to our earth and everything on it. The sun gives health for we need different wavelengths of its splendor. The sun is a primal medicine as is water. We do need to treat the sun with respect, as the dermatologists insist.

Health professionals recommend getting at least 5-30 minutes of sun exposure daily—no sunscreen invited. Sound easy? Well, for those living too far from the equator, getting that daily sunshine fix can be tricky. Even short periods of direct peak sun exposure — 15 minutes 3 times a week, for example — can give you some of the recommended daily amount of vitamin D if you live in the lower latitudes. It is impossible to overdose on vitamin D from the sun though of course one can burn.      More
