Introduction to the earth's climate from a, physical, earth-systems perspective. Prehistoric, and historic fluctuations in the earth's climate,, the current climate system, and projections for, future climate and climate impacts. Topics will, include the radiative balance of the earth's, atmosphere, the greenhouse effect, albedo,, aerosols, clouds, climate feedbacks, ocean, circulation, climate variability including El Nio, and the Pacific decadal oscillation, the carbon, cycle, paleoclimate proxy records, ocean, acidification, and climate models. We will examine, some responses to climate change, including, geoengineering, adaptation, and mitigation. Weekly, laboratory exercises with climate data, observations and models (computer-based), and, physical mechanisms (lab- and field-based)., Lecture and lab.
