Scientists Want to Block the Sun to Stop El Niño
Scientists are exploring a radical plan to block a small portion of sunlight reaching Earth in an effort to weaken extreme climate events like El Niño. The idea sounds like science fiction, but researchers are seriously studying technologies that could reflect sunlight back into space and temporarily cool parts of the planet. Supporters argue it could reduce devastating heat waves, droughts, floods, and other climate-related disasters, while critics warn that altering Earth's climate system could have unpredictable consequences. This video explores the science behind solar geoengineering, why some experts believe it could help control El Niño, and the risks that have sparked intense debate around the world. The question is no longer whether humans can influence the climate - it's whether we should.Credit:
