In Sound of Sirens: Tabula Rasa, the first of a two-part series, G.E. Johnson frames the present condition of a growing global civilization and describes the sensitive systems of planet Earth concerning global temperature change. At the beginning of the 21st century, people around the world rely on complex systems to provide basic necessities, security, and prosperity. These systems depend and are based on the foundation of stable and predictable weather patterns provided by today's average global surface temperature and corresponding climate regimes. This foundation is changing. G.E. Johnson is a pioneer in the discussion on adapting human settlements to a changing planet during the 21st century.
