If you wish to study the underlying causes of a specific disease, you start by examining an animal model that would simulate the human condition. If you want to study a subset of geological events on earth, Biosphere 1 , you might design a miniature system, but what do you do if you want to study the earth’s entire complex geology, environment, and ecology? Well, you build Biosphere 2. And so, in 1987 a vision was born, to assemble steel, concrete, soil, sea water, and plants to build a model of Biosphere 1 consisting of five biomes and 8 humans who would live for two years. While this unprecedented, experiment’s outcomes were not what was anticipated, the idea was sound, the concepts testable, the facility unique, and the science eventually became rigorous, exciting, and yielding results applicable not only to our own earth, but also to possibilities of imitating Biosphere 1 extra terrestrially. Today, B2 is the largest earth science living laboratory in which precise scientific explorations are underway as part of the University of Arizona’s mission.

For two decades, John Adams has helped drive the evolution of Biosphere 2. Starting in 1995, he lead the terrestrial research initiatives exploring the effect of elevated CO2 on the complex mesocosms of Biosphere 2. Building on his deep knowledge of the facility and its science, Adams became Biosphere 2's Media Coordinator and Public Spokesperson in 1999, fielding inquiries from around the world, building public understanding of the University's groundbreaking earth systems science research and developing its K-12 education programs ("Passport to Learning™).

A broadly trained earth scientist, Joost van Haren has researched topics from 40km deep in the earth’s crust to soil-plant-atmosphere interactions. Joost came to Arizona in 1995 to run the analytical facilities at Biosphere 2. Currently, Joost is an assistant research professor and interim research director at the University of Arizona Biosphere 2, where he investigates carbon uptake by weathering of basalt in the Landscape Evolution Observatory and increased temperature and drought effects on carbon cycling rates in the tropical rainforest.

About the University of Arizona:
The University of Arizona, a land-grant university with two independently accredited medical schools, is one of the nation's top 40 public universities, according to U.S. News & World Report. Established in 1885, the university is widely recognized as a student-centric university and has been designated as a Hispanic Serving Institution by the U.S. Department of Education. The university ranked in the top 20 in 2019 in research expenditures among all public universities, according to the National Science Foundation, and is a leading Research 1 institution with $734 million in annual research expenditures. The university advances the frontiers of interdisciplinary scholarship and entrepreneurial partnerships as a member of the Association of American Universities, the 66 leading public and private research universities in the U.S. It benefits the state with an estimated economic impact of $4.1 billion annually.
