Considered by some to be the stuff of science fiction, an electromagnetic pulse (EMP) attack poses a direct threat to the U.S. electric grid a threat that is poorly understood and lacks the leadership to address it. An EMP a high-intensity burst of energy caused by a rapid acceleration of charged particles from either solar weather or a nuclear bomb detonated high in the atmosphere has the potential to cause devastating damage to the U.S. electric grid and severely impede recovery efforts.
Space weather refers to conditions in the region of space that is affected by the sun. It is tricky to predict and can wreak havoc on the technological world.
