Environmental Science and Engineering (ESE) AB and SB interdisciplinary programs focus on understanding, predicting, and responding to natural and human-induced environmental change. Addressing environmental issues such as global warming, stratospheric ozone depletion, or local and regional air and water pollution requires perspectives from a diverse set of scientific disciplines including atmospheric physics and chemistry, oceanography, glaciology, hydrology, geophysics, NetBet Pokerecology, and biogeochemistry. We view the environment as a complex set of chemical, physical, and biological interactions, made even more complicated by the various activities of human society.

At Harvard College, students choose a "concentration," which is what we call a major. All prospective undergraduate students, including those intending to study engineering and applied sciences, apply directly to Harvard College. During your sophomore spring you’ll declare a concentration, or field of study. You may choose from 50 concentrations and 49 secondary field (from Harvard DSO website).

Through exploration of the underlying processes and feedback within the Earth system, and with a range of approaches from theory and modeling to experiments and observations, we train students to netbet live casinothink about environmental processes in an integrated fashion, preparing them to manage the environmental challenges we face.
