Abstract

Complexity and Organization in Earth Systems

Planet Earth could well be called “Planet
Water.” Seventy percent of its surface is covered by water. A not so far-fetched
analogy is that for Earth water is lifeblood and lymphatic fluid.style="mso-spacerun: yes">   Just like our circulatory system,
the hydrologic cycle moves water and energy throughout the “body-Earth”,
sustaining and cleaning it.


 


The hydrologic cycle is an exquisitely
coordinated, balanced, interaction between the atmosphere, the oceans, and the
land that controls, among other things, the planet’s temperature by moving large
quantities of matter and energy. The system is incredibly complex with a myriad
of positive and negative feedbacks acting at a variety of scales. Much of what
we experience in our natural and altered environments results from these complex
interactions. Surprisingly (or maybe not) this complexity many times results in
beautifully organized expressions of the hydrologic state that are commonly
amenable to fairly simple explanations.


 


This talk explores some outcomes of the
hydrologic complexity and organization with examples of over 30 years of work.
Topics include the impact of soil moisture on the atmosphere and vice-versa, the
impact of deforestation on the Amazon cloud climate, the self-organization of
landscapes and river basins over very long time periods and the roles of
vegetation on landscape evolution and in turn the role of the landscape on
vegetation distribution.
