"Scientists have recently come to recognize that some of the widely dispersed climatic extremes affecting the earth might have a common origin in the phenomena of El Nin~o--the periodic warming of sea surface water in the central and eastern equatorial Pacific Ocean. This book explains in simple terms what El Nino is, how its effects might be forecast and its far reaching impacts on all of us." - Publisher.
