Bill Gates wants to spray millions of tonnes of CHALK into the stratosphere to reflect sunlight and slow global warming + ramifications of breathing in chalk and dust in general

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.

Aside from the fact that we're in Solar Cycle 25, which means the sun is quite inactive right now with very few sun spots, what kind of damage can chalk dust do?

A small amount of inhaled dust is not considered harmful. Those with healthy respiratory systems can expel it through coughing, and the remaining material should be absorbed safely into the body. For those with chronic breathing issues such as asthma, however, exposure can trigger a reaction. In fact, many school systems strongly urge teachers to move students with respiratory problems away from the chalkboard area. Chalkboards, trays and erasers filled with dust should also be cleaned regularly.

Teachers who used traditional chalk for a number of years developed some respiratory problems.

Chalk dust is considered an irritant and an occupational hazard by a number of occupational safety organizations around the world. People who must work around it for extended periods of time may want to use a filtered mask over the mouth and nose and taking a number of breaks in a fresh air environment.

Beyond the human health aspects of chalk dust exposure, there are also potential electronic hazards. Devices such as computers and digital versatile disc (DVD) players stored inside classrooms can suffer damage from accumulated dust. As the chalk particles circulate throughout the room, cooling fans may draw them into the computers' inner workings. As it builds up on the motherboard and other heat-sensitive parts, the risk of overheating increases. This dust can also cause severe damage to sensitive electronics, such as the laser reader of a DVD player or the playback heads of a video cassette recorder (VCR).

Particles that evade elimination in the nose or throat tend to settle in the sacs or close to the end of the airways. But if the amount of dust is large, the macrophage system may fail. Dust particles and dust-containing macrophages collect in the lung tissues, causing injury to the lungs.

The amount of dust and the kinds of particles involved influence how serious the lung injury will be. For example, after the macrophages swallow silica particles, they die and give off toxic substances. These substances cause fibrous or scar tissue to form. This tissue is the body's normal way of repairing itself. However, in the case of crystalline silica so much fibrous tissue and scarring form that lung function can be impaired. The general name for this condition for fibrous tissue formation and scarring is fibrosis. The particles which cause fibrosis or scarring are called fibrogenic. When fibrosis is caused by crystalline silica, the condition is called silicosis.

Some types of lung diseases caused by the inhalation of dust are called by the general term "pneumoconiosis". This simply means "dusty lung".

Some particles dissolve in the bloodstream. The blood then carries the substance around the body where it may affect the brain, kidneys and other organs.

Use of personal protective equipment may be vital, but it should nevertheless be the last resort of protection. Personal protective equipment should not be a substitute for proper dust control and should be used only where dust control methods are not yet effective or are inadequate. Workers themselves, through education, must understand the need to avoid the risks of dust.

As to volcanic output I grasp the gulf between our total CO2 and methane emissions but 3-10% of global CO2 is significant it could imbalance the carbon cycle or accelerate natural climate changes.

Im all for reducing humanity's pollution in responsible and sustainable ways, HOWEVER I think 80% of the modern left's tactics and methods are foolish, irresponsible, and ignore the biggest threats.

Increasing oxygen production is vital, reducing noxious and toxic pollutants falling out unto nature, punishing corporations and executives for human and ecological harm, creating a Commission on genetic modification safety and approval which is barred from the use of redaction, dramatically depopulating africa to prevent them from entering a stage of development where they produce electricity and air conditioning en masse, reducing reproduction rates in south asia and china, and south america. Developing waste transportation pipelines which fight desertification, intentionally spreading corals and sea flora and using selective breeding techniques to spread more or better adapted flora into ecologically appropriate regions of the sea floor. Engineering/breeding trees to be used in cities for greenery and shade to fight heat island effects, investing in low upkeep solar power, more sustainable low capital wind power both for home and industrial use, a massive research investment to develop thorium as a safer nuclear power source that we can trust lesser nations with and also assuage fears iver nuclear power in the west.

If the left cared about man made climate change as much as they say we wouldn't be killing western civilization, pushing brown world economic development, trying to make more inefficient energy distribution systems, supporting east asian tech companies and shipping jobs to asia, tolerating disposable technology and appliances and buying new phones every year.

If the left actually cared as much as they pretend to, we would be trying to genocide africa and put south asia, from the levant to the Philippines, on female hormones and that gay/tranny shit and get chinese men to marry their trannies. We wouldn't be allied with OPEC or saudis or Israel we would tell every country to develop their local assets and become fuel independent to reduce transportation waste and accidents. We would be sanctioning the top polluters no matter their economic power or frailty.

I'm tired of mercury in the fish, asthma in our children, oil in the shrimp, and nuclear radiation pouring into the pacific and tainting food supplies.

I'm no ecofascist but I'm sure they'd fawn over somebody like me running for office.

I might give it a read. When you say world wide consequences do you mean temperature variations altering jet streams or rain cycle disruption from cloud seeding or atmospheric fallout being a much larger scale phenomena than one would casually reckon? Or some mix of all that?
