Extreme Solar Particle Event

Summary: Extreme solar particle events, occurring about once every thousand years, involve the sun emitting massive amounts of protons, which can significantly impact Earth. The most recent event was recorded in 993 AD. These events can damage Earth's ozone layer, leading to increased ultraviolet (UV) radiation reaching the surface, which raises the risk of skin cancer and DNA damage. Studies by Alan Cooper and Pavle Arsenovic highlight that such events, especially when Earth's magnetic field is weak, could have severe and prolonged effects, including up to a 25% increase in UV exposure and a 50% increase in DNA damage lasting up to six years. Continuous monitoring and protective strategies are essential to mitigate these potential hazards.
