Representative Roscoe Bartlett (R-MD) and others talked about the threat of electromagnetic pulse (EMP) to the U.S. infrastructure. An EMP, produced by detonating human-made devices or by powerful solar storms, can disrupt and destroy electrical systems, including the U.S. power grid. Panelists warned of an aftermath similar to “Hurricane Katrina” of an EMP event, predicting that as many as two-thirds of Americans could die from starvation.
