Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to:Define global climate changeSummarize the effects of the Industrial Revolution on global atmospheric carbon dioxide concentrationDescribe three natural factors affecting long-term global climateList two or more greenhouse gases and describe their role in the greenhouse effect

" This class examines tools, data, and ideas related to past climate changes as seen in marine, ice core, and continental records. The most recent climate changes (mainly the past 500,000 years, ranging up to about 2 million years ago) will be emphasized. Quantitative tools for the examination of paleoceanographic data will be introduced (statistics, factor analysis, time series analysis, simple climatology)."

12.000 Solving Complex Problems is designed to provide students the opportunity to work as part of a team to propose solutions to a complex problem that requires an interdisciplinary approach. For the students of the class of 2013, 12.000 will revolve around the issues associated with what we can and must do about the steadily increasing amounts CO2 in Earth's atmosphere.Each year's class explores a different problem in detail through the study of complementary case histories and the development of creative solution strategies. It includes training in Web site development, effective written and oral communication, and team building. Initially developed with major financial support from the d'Arbeloff Fund for Excellence in Education, 12.000 is designed to enhance the freshman experience by helping students develop contexts for other subjects in the sciences and humanities, and by helping them to establish learning communities that include upperclassmen, faculty, MIT alumni, and professionals in science and engineering fields.
