Synopsis: Water, its availability and its unique physical properties, is a partner with solar radiation among the primary agents that drive weather and climate. The cycling of water through the Earth's environment is the yin and yang of water − a benefactor sustaining humankind's food supplies, facilitating transportation and producing power, while conversely an adversary responsible for droughts, floods, wildfires and landslides. If the climate is changing, then, without doubt, water, being the most abundant greenhouse gas − far more so than the nearest candidate, CO2 − will be a principal player in the atmosphere, land processes, in the oceans and rivers, and in the soil. But, how this role will be played out remains elusive to science; we first need to understand the "normalcy" of water processes. We need to understand the normal behavior of water − even as we need to understand what are normal extreme events. This course is a qualitative/semi-quantitative introduction to the underlying causes of floods, droughts, wildfires, and hurricanes in the context of environmental processes globally driven by the unique character of water, and by its regional abundance or scarcity. We explore the foundations for understanding the physical mechanisms by which water is transported throughout a hydrologic system, emphasizing the fundamental inter-coupling of atmospheric, surface, soil and ground water. While providing background for future studies, the course is primarily designed to enable informed citizens to thoughtfully critique and comment on fundamental issues of public policy. A pre-college math and physics background is expected.

This course is primarily designed to be a forum in which humanities and science students might explore topics of common interest.
