EMP: How a High-Altitude Nuclear Burst Could Disable a Continent
A single nuclear burst about 200 miles (320 km) above the central United States could expose almost the entire country, plus parts of Canada and Mexico, to EMP. Here is how the effect works and how seriously experts take the threat.

Nuclear Winter: How a Regional War Could Cool the Earth
A 1980s climate hypothesis turned out to be more robust than originally thought — and recent modeling shows that even a regional nuclear war could cause global crop failures.
