"Proposed: Using a Giant Umbrella in Outer Space to Combat Global Warming"

Scientists are proposing the idea of deploying a giant sunshade in outer space to counter global warming by blocking a small portion of solar radiation. Various approaches, such as scattering dust into space and creating shields made of "space bubbles," are being explored. Researchers are now ready to build a prototype shade to demonstrate the concept, seeking funding for a 100-square-foot model. While a full-size version would cost trillions, it could potentially reduce Earth's temperature by 1.5 degrees Celsius within two years, offering a potential solution to the climate crisis.
