Fully understanding the nature of the relationships between Arizona’s climate and the conditions of its natural resources is no simple task, says Fulton Schools Professor Enrique Vivoni. Many fluctuating and unpredictable factors can influence how Arizona’s various environments change and impact the climatological conditions under which the state’s residents live. Droughts, heatwaves, floods, varying atmospheric fluctuations and many other things shaped by the forces of nature, and by the actions of the human population, can make maintaining environmental health and stability in Arizona an especially complex and long-term challenge.
