    Gregg Garfin, a University of Arizona expert on climate science and policy, has been elected a 2020 Fellow of the American Association for the Advancement of Science, the world’s largest general scientific society.

    Garfin joins a roster of nearly 500 AAAS members who have earned the lifetime distinction. He is being recognized for his work linking fundamental climate and paleoclimate science to climate services and decision making, through climate assessment, knowledge exchange and the development of translational ecology.

    Garfin has worked for the last 20 years to bridge the science-society interface through dialogues between scientists and decision-makers and collaborative climate and environment research projects.

    His research focuses on adaptation to a changing climate, climate variability and drought, especially in southwestern United States and northern Mexico. He was co-lead author of the Southwest chapter of the Fourth National Climate Assessment. The congressionally mandated report is written every four years to help inform decision-makers and other stakeholders by providing a thorough examination of the effects of climate change on the United States. Decision-makers include utility and natural resource managers, public health officials and emergency planners.

    $3M Grant Helps Students Bridge Sciences to Solve the World's Biggest Problems

    A grant from the National Science Foundation will help the University of Arizona train the next generation of interdisciplinary scientists who can "scale across genes to ecosystems" to understand how wild and agricultural systems function and respond to change.

    A $3 million grant from the National Science Foundation will support University of Arizona graduate students looking to work across scientific disciplines to take on the world's grand challenges, from global climate change to sustainable food production.

    The grant was awarded to researchers with the UArizona Ecosystem Genomics Initiative, which brings together researchers from a wide range of scientific fields to design new models to inform global climate policy, identify genes and genomic interactions that enhance crop yield, and prepare graduate students to join the national workforce in fields such as ecosystem management, medical genetics and food security.

    Hotter and Drier With a Chance of Extinction: Forecasting Biodiversity With Big Data

    With $2.5 million from the National Science Foundation, a national team of collaborators, including researchers at the University of Arizona, aims to harness the power of big data to predict the fate of global biodiversity in the wake of environmental change.

    Species are on the move. Those that thrive in moist, cooler environments are quietly disappearing, while those that tolerate hotter, drier conditions are moving in to take their places.

    These are just some of the changes among plants, animals and ecosystems that Brian Enquist, a professor of ecology and evolutionary biology at the University of Arizona, has witnessed over time, through data and with his own eyes.

    Enquist frequently conducts fieldwork in the tropics and in alpine mountain environments, where, he says, biodiversity changes in response to global environmental changes are now clearly apparent and accelerating.

    "When we talk about climate change, we tend to think about changes in temperature and rainfall," Enquist said.

    While scientists have created increasingly more accurate models to predict how global temperatures, forest fire patterns or sea levels will change under different greenhouse gas emission scenarios, little has been done to predict similar changes in the biosphere, he said.

    UArizona Mission Members Celebrate OSIRIS-REx Success

    Members of the University of Arizona-led OSIRIS-REx mission, along with UArizona leadership, gathered to watch NASA's live broadcast of the mission's much-anticipated Touch-and-Go, or TAG, sampling event.

    If NASA's OSIRIS-REx spacecraft could talk, today it might have said, "Finally!"

    At 10:50 a.m. Tucson time, the van-sized spacecraft fired its thrusters to leave the safe-home orbit around asteroid Bennu and began descending toward the asteroid's surface, which the spacecraft spent two years photographing and mapping in tremendous detail. Its mission: Touch the asteroid for a few seconds and collect a sample to be later brought back to Earth. 

    Members of the University of Arizona-led OSIRIS-REx mission, along with UArizona leadership, gathered at the university's Michael J. Drake Building, where the mission is headquartered, to watch NASA's live broadcast of the mission's much-anticipated Touch-and-Go, or TAG, event and listen to status updates from the spacecraft.

    At 3:13 p.m. Tucson time, the atmosphere inside the building changed from one of subdued anticipation to elation and relief as a physically distanced, masked crowd started to clap and cheer.

    At that time, the mission's spacecraft confirmed that it had touched the surface of asteroid Bennu for 4.7 seconds and triggered a flush of nitrogen gas with the goal of collecting the largest sample of extraterrestrial material since the Apollo moon landings.

    "I can't believe we pulled this off," Dante Lauretta, principal investigator of the OSIRIS-REx mission and a UArizona professor of planetary sciences, said from the mission control room at Lockheed Martin in Denver, where NASA's broadcast was based. "This is history. This is amazing."
