Why would anyone build an enormous glass structure in the Arizona desert? In Module 1, you will get a virtual introduction to the engineering marvel that is Biosphere 2. Learn about the fascinating history of Biosphere 2 and how it is currently used as the world’s best research instrument for earth systems science. Discover how the ocean, rainforest, and desert can be studied in one enclosed, three-acre structure in the Arizona desert. With Dr. Joaquin Ruiz, University of Arizona (UA) Vice President for Innovation, Director of Biosphere 2, Dean of UA Science, Geoscientist, and John Adams, Deputy Director, UA Biosphere 2.

How do we know that human activity is changing the climate? In Module 2, you will hear from scientists who reconstruct past climates by unlocking information held in ancient trees. Discover how tree rings help us understand drought and wildfire patterns across time and space. Learn what global warming is, exactly, and how it is accelerated by carbon emissions. With Dr. Kevin Anchukaitis, Geography and UA Laboratory of Tree-Ring Research, and Dr. David Frank, UA Laboratory of Tree-Ring Research.

Where is Earth’s water? In Module 3, you will learn about the global water cycle and discover how much water exists, where it exists, and how it moves around the environment. Learn how Biosphere 2 and Critical Zone research are used to study the water cycle. With Dr. Peter Troch, Director of Science at Biosphere 2, UA Hydrology.

How can many different species coexist in once place? In Module 4, go beyond Biosphere 2 to UA Tumamoc Hill—the world’s oldest long-term desert ecology research site near the University of Arizona. Learn how living and nonliving components of the environment are related, how different species coexist, and how climate variation affects Sonoran Desert plants. With Dr. Larry Venable, UA Ecology & Evolutionary Biology.
