The basic controls on Earth’s climate are simple. We take in light energy from the sun, we radiate that energy through our atmosphere back into space, and the balance of inputs and outputs sets our surface temperature. Thus, changes in solar radiation, Earth’s orbital dynamics, and atmospheric chemistry can explain the large-scale climate changes throughout Earth’s history.

The majority of Earth’s volume is composed of igneous and metamorphic rocks, which originate through processes that operate deep beneath earth’s surface, driven by the movement of tectonic plates. Igneous and metamorphic rocks preserve an interpretable record of the creation and modification of continents, mountain building, earthquakes, and volcanic eruptions. The formation and existence of these rocks, in turn, modulate global volatile cycles, and the evolution of life-forms on earth.

As the global human population expands in a future marked by climate change, the search for and preservation of our most vital resource, water, will demand thoughtful policy and greater scientific understanding. This course is an introduction to surface and groundwater hydrology, geochemistry, and management for natural systems and human needs. Lectures will focus on understanding the hydrologic cycle, how water flows over and within the earth, and the many ways in which this water is threatened by contamination and overuse. Three hours of lecture and three hours of lab each week.

For at least 3.5 billion years, Earth’s surface environments have supported some form of life. What geologic processes first created and subsequently maintained a habitable environment? How does contemporary global climate change compare to climate variations over Earth’s long history? This course looks at Earth’s climate and its surface environment from a geologist’s perspective. We will develop an understanding of the atmospheric, oceanographic, geological, and biological systems that interact to modulate the climate.
