Hypoxia is the effects of an insufficient supply of oxygen to the body. Every person can have different symptoms when suffering from hypoxia (U.S. Air Force aircrews are required to take an altitude chamber ride every three years to reinforce and identify their hypoxic symptoms). Some of the common symptoms are: lightheaded sensation, dizziness, reduced vision, and euphoria.

El Niño-Southern Oscillation (ENSO) is a quasi periodic climate pattern that occurs across the tropical Pacific with a roughly 5 year cycle. It is composed of an oceanic component, called El Niño (or La Niña), which is characterized by warming or cooling of surface waters in the tropical eastern Pacific Ocean.
