This document discusses the transition from the Earth Era to the Air Era according to Western astrology. Every 200 years, one of the four elements of earth, air, fire, or water is said to dominate. 2020 marks the beginning of the Air Era, taking over from the Earth Era that began in 1842. The document notes some short-term conjunctions between 1981-2020 that represent a tug of war between the two eras. After 2020, the document predicts a shift from material to non-material values and from stability to reform at various levels as the Air Era fully takes hold.
