Professor of Atmospheric Sciences
Tim Garrett is a professor of atmospheric sciences at the University of Utah. In addition to researching clouds, he applies physics principles to societal phenomena. Garrett's groundbreaking work revealed a fixed relationship between the wealth of civilization and energy consumption, which suggests that only a rapid decline in the global economy tantamount to the collapse of civilization will prevent catastrophic global warming.
