Make your commitment to our planet’s future, here at Biosphere 2.

For the past ten years, the University of Arizona Biosphere 2 has been diving deeper, looking closer and advancing science on an unparalleled scale to better understand our changing planet. On Earth Day, meet the UA faculty who are probing the complex couplings of life, energy, and water that drive our dynamic world. Their cutting-edge exploration of Biosphere 2’s model ecosystems and its Landscape Evolution Observatory is like nowhere else on Earth.

Gain up-to-the-minute insights on global issues from leading scientists. 

Engage in our series of moderated panel discussions on topics critical to the future of life on our planet: Earth, Energy, Water and Food. A keynote speaker will introduce the panels where scientists from across the nation will participate in this main-tent event. Panel discussions begin at 1PM.
