From the poineering ballonists to orbiting weather stations, EARTH'S AURA is filled with unexpected discoveries and dramatic challenges of the unknown: the legendary wind sirocco which blows red sahara sand across the sea to "shower blood" on Europe, the effects of solar wind, fallout, pollution, and ozone depletion in our climate; the hair raising account of two balloonists who in 1862 ascended to the unbelievable height of 30,000 feet without oxygen! Here is a brilliantly guided grand tour of our atmosphere, written in a readable style that unlocks the secrets of the layer of vapors, that is more to us than the air we breath! (from the back cover)
