For St. Simons Island native Jonah Driggers, the ecology of the small island community has instilled a sense of mission that has been shaped by his UGA experiences:

Although I began my freshman year with vague intentions of pursuing a career in business, I always harbored a love of the outdoors that was developed over years of Scouting and working in the garden with my dad. Experiences made possible through the Foundation Fellowship, like taking Modernist Dystopian Literature with David Bradshaw at Oxford University and hiking the Tour du Mont Blanc with two of my best friends,...

Satellite data show Georgia salt marsh health decline

Scientists at UGA's Marine Institute at Sapelo Island have found that the amount of vegetation along the Georgia coast has declined significantly in the last 30 years, spurring concerns about the overall health of marshland ecosystems in the area:

Using data collected by NASA's Landsat TM 5 satellite, which provided 28 years of nearly continuous images of the Earth's surface between 1984 and 2011, the researchers found that the amount of marsh plant biomass had dropped 35 percent. They published their findings recently in the journal Remote Sensing.

This sharp decline is...

Climate Feedback

Not the feedback loop, but fact-checking media reports. In perhaps the next iteration of evaluating climate news and data, how trustworthy is the science you read about? A new group will track the accuracy of climate news to evaluate what's out there:

Last week, Climate Feedback announced the Scientific Trust Tracker, a feature that will track news outlets’ accuracy on climate change, one scientist-reviewed story at a time. Right now, the Trust Tracker has preliminary data for five outlets: The New York Times, Mashable, the Washington Post, the Telegraph, Forbes, and the Wall Street...

Jill Anderson, an assistant professor of genetics, has received a $1.1 million grant from the National Science Foundation Early Career Development Program to study the effects of climate change on plants. Among the NSF's most prestigious, CAREER awards support junior faculty who exemplify the role of teacher-scholar and the integration of education and research:

Anderson's project tests whether plants will be able to survive on a warming planet by using a mustard plant species called Drummond's rockcress as a model. Native to the Rocky Mountains, Drummond's rockcress can grow at...

Tracking the Greenland meltwater

Very interesting work in the context of a significant increase in the melting of glacial land ice on the island of Greenland due to atmospheric warming:

a team of researchers led by faculty at the University of Georgia has discovered the fate of much of the freshwater that pours into the surrounding oceans as the Greenland ice sheet melts every summer. They published their findings today in the journal Nature Geoscience.

"Understanding the fate of meltwater is important, because research has shown that it can carry a variety of nutrients, which may impact biological...
