Space Weather Environment and Societies Our planet exists within a space environment affected by constantly changing solar atmosphere producing cosmic particles and electromagnetic waves. This space weather profoundly influences the performance of our technology because we primarily use two means for transmitting information and energy namely electromagnetic waves and electricity. On an everyday basis we have developed methods to cope with the normal conditions. However the sun remains a fiery star whose angry outbursts can potentially destroy spacecrafts kill astronauts melt electricity transformers stop trains and generally wreak havoc with human activities. Space Weather is the developing field within astronomy that aims at predicting the suns violent activity and minimizing the impacts on our daily lives. Space Weather Environment and Societies explains why our technological societies are so dependent on solar activity and how the Sun disturbs the transmission of information and energy. Footnotes expand specific points and the appendices facilitate a more thorough command of the physics involved.
