Project travels up estuaries to find tipping points

Department of geography researchers are collaborating with faculty from the Warnell School of Forestry & Natural Resources and the College of Agriculture and Environmental Sciences on a four-year project supported by a grant from NOAA to connect marsh health with local economics and environmental impact. Our colleagues in the Warnell School report: The forces at work in a marsh require a delicate balancing act. Rising and falling tidewaters…

Adapting Roots to a hotter planet could ease pressure on food supply

The shoots of plants get all of the glory, with their fruit and flowers and visible structure. But it's the portion that lies below the soil — the branching, reaching arms of roots and hairs pulling up water and nutrients — that interests plant physiologist and computer scientist, Alexander Bucksch, associate professor of Plant Biology at the University of Georgia. The health and growth of the root system has deep implications for our…

Georgia Climate Project receives $300K Anderson Foundation grant

The Ray C. Anderson Foundation has awarded a $300,000 grant to Emory University and its partners for the next phase of the Georgia Climate Project, a state-wide consortium of nine colleges and universities working to strengthen Georgia’s ability to prepare for and respond to a changing climate.   The Georgia Climate Project was founded in 2018 as a collaborative effort among Emory University, the Georgia Institute of Technology and the…

How people solve global problems

What do the 3,000-year-old actions of an Egyptian pharaoh say about how we should tackle the biggest challenges of the 21st century? Quite a bit, according to anthropologists at the University of Georgia who analyzed archeological evidence over thousands of years to examine how societies have approached adversity. Their work suggests that rigid, top-down approaches to complex problems have been a doomed strategy throughout human history.…

Focus on the Faculty: Sally Walker

Sally E. Walker, the inaugural Shellebarger Professor in Geology in the Franklin College of Arts and Sciences, gives students field research experiences through which they propose hypotheses, collect and analyze data, and communicate their findings: What are your favorite courses and why? My favorite courses concern connections: how evolution of life on Earth affected geological and atmospheric processes and vice versa. The naturalist John Muir…

New Research Reveals Effect of Global Warming on Greenland Ice Melt, Consequences for Sea Level Rise

New analysis of almost 30 years’ worth of scientific data on the melting of the Greenland Ice Sheet predicts global sea level rise of at least 10 centimetres by the end of the 21st Century, per global warming trends. The estimates, which scientists warn are “conservative” given the powerful effects of changes in weather systems and possible ways of accelerating ice loss, are broadly consistent with recent predictions reported by…

Cyanotracker created to detect toxic algae

Outbreaks of harmful algae have increased in recent years due to warming trends and longer summer seasons. Also called cyanobacterial algal blooms or CyanoHABs, these large-scale ecological disturbances are often caused by increased urbanization, nutrient pollution, poor waste management and warming weather. The algae can produce toxins that are harmful to humans, pets and aquatic ecosystems. The CyanoTRACKER project, a collaboration between…

Ancient oyster shells provide historical insights

An interdisciplinary team of scientists studying thousands of oyster shells along the Georgia coast, some as old as 4,500 years, has published new insights into how Native Americans sustained oyster harvests for thousands of years, observations that may lead to better management practices of oyster reefs today. Their study, led by University of Georgia archaeologist Victor Thompson, was published July 10 in the journal Science…

Joye consults on new video game ‘Beyond Blue’

In a gaming experience that takes players into the near future to explore the mysteries of the ocean, “Beyond Blue” is a new video game launched by E-Line Media in conjunction with the BBC and the researchers behind its “Blue Planet II” series. The game allows players to become part of a new research team using groundbreaking technologies to see, hear and interact with the ocean in a meaningful way. University of Georgia Regents’ Professor…

Plant physiology and river flooding

Earth system scientists have identified another culprit (other than rain) that causes a river to overflow its banks: leafy plants. In a study published today in Nature Climate Change, the UCI researchers describe the emerging role of ecophysiology in riparian flooding. As an adaptation to an overabundance of carbon dioxide in the atmosphere, trees, plants and grasses constrict their stomatal pores to regulate the amount of…

Scientists assess storage value in blue carbon ecosystems

When Hurricane Dorian roared up the East Coast during the first week of September, the places where people live and work in several states were under threat. The first line of protection against storm damage was made up of coastal vegetated ecosystems, including nearly 300,000 acres of salt marshes in Georgia. The salt marsh, seagrass, and mangrove ecosystems that bore the brunt of pounding waves are not, however, immune from damage.…

Amazing student: Sarah Saddoris

For plant biology major and Goldwater Scholar Sarah Saddoris, research has played a primary role in defining her goal to improve the production of the global food supply: As my primary focus, research has played a defining role in my studies. I have spent my fair share of Friday nights in the lab finishing experiments at 2 in the morning and many game days in Davison Life Sciences (benchwork waits for no man!). I have…

Studying the impact of climate change on Georgia archaeology sites

In the world of climate change studies, there are extensive global and regional models but fewer site-specific models. Lindsey Cochran, a postdoctoral research associate with the University of Georgia Laboratory of Archaeology, is working with digital data from the Georgia coast to recreate models that simulate site-specific changes from now until 2100. “Archaeologists care a lot more about the context in which an artifact was found than the…

Deer teeth unveil climate mystery of the Mayans

Though causes of the civilizational collapse that took place in the Maya lowlands of southeastern Mexico and Central America during the Terminal Classic Period (1200 – 900 before present) remain uncertain, changing precipitation patterns have long been suspected. Now, a new study from the University of Georgia and the Florida Museum of Natural History establishes fossilized white-tailed deer teeth as part of the climate record, a reliable proxy…
