how will Bill Gates dim the sun?
Answers
Answer:
It is thought that global dimming is probably due to the increased presence of aerosol particles in Earth's atmosphere, caused by pollution, dust, or volcanic eruptions. ... The smaller droplets make clouds more reflective, so that more incoming sunlight is reflected back into space and less reaches the Earth's surface.A group of Harvard scientists plans to tackle climate change through geoengineering by blocking out the sun. The concept of artificially reflecting sunlight has been around for decades, yet this will be the first real attempt at controlling Earth's temperature through solar engineering

Microsoft’s MSFT billionaire founder Bill Gates is financially backing the development of sun-dimming technology that would potentially reflect sunlight out of Earth’s atmosphere, triggering a global cooling effect. The Stratospheric Controlled Perturbation Experiment (SCoPEx), launched by Harvard University scientists, aims to examine this solution by spraying non-toxic calcium carbonate (CaCO3) dust into the atmosphere — a sun-reflecting aerosol that may offset the effects of global warming.
