Program Description

A massive planet-sized machine controls the world's weather day-by- day, and the climate season by season. It takes an event of staggering proportions to disrupt a machine this large and powerful, a juggernaut with more energy than a million nuclear bombs. Such an event is underway -- El Nino. El Nino is second only to the seasons in its effect on global weather. As scientists push to extremes to explore this phenomenon, they are understanding for the first time the extent to which all the world's weather is connected -- and just how delicate is the balance.
