Scientists are exploring the concept of reflecting sunlight into space as a potential means to combat global warming, but this approach, known as solar geoengineering, also raises concerns about its potential impact on ecosystems and sleep patterns. Some experts warn that the use of such technology could be misused by "rogue nations". The effectiveness and potential risks of solar geoengineering are being debated, with some studies investigating its potential to slow global warming and others highlighting its potential drawbacks.
