Rising temperatures in the tundra of the Earth’s northern latitudes could affect microbial communities in ways likely to increase their production of greenhouse gases methane and carbon dioxide, a new study of experimentally warmed Alaskan soil suggests.
Professor John Crittenden and President Emeritus G. Wayne Clough have helped chart the course for the future of environmental engineering in a new report from the National Academy of Engineering. Environmental Engineering for the 21st Century: Address Grand Challenges lays out five grand challenges facing society that environmental engineers are uniquely positioned to address — but answering these challenges will require an evolution in environmental engineering education, research and practice, according to the report.
The soon-to-be-released second State of the Carbon Cycle Report includes work from some of the nation’s leading scientists — including contributions from a civil engineer who just finished his Ph.D. at Georgia Tech.
From the drinking-water contamination in Flint, Mich., to the seemingly endless drought in California, good old H2O pools at the heart of many of today’s most pressing and headline-grabbing problems. Find out how the work and ideas of Tech researchers are helping us understand — and solve — these planet-wide challenges.
Sea walls aren’t enough to protect the world’s coastal communities from inundation as sea levels rise. In fact, Georgia Tech President Emeritus G. Wayne Clough tells web magazine Line//Shape//Space, no single strategy will.
In ocean expanses where oxygen has vanished, newly discovered bacteria are diminishing additional life molecules. They help make virtual dead zones even deader. Now, a team led by the Georgia Institute of Technology has discovered members of a highly prolific bacteria group known as SAR11 living in the world’s largest oxygen minimum zone. The team has produced unambiguous evidence that the bacteria play a major role in denitrification.
A high-resolution model of how soil erosion impacts the carbon cycle of a small South Carolina watershed may help explain an apparent imbalance in the world’s carbon budget. Explaining that apparent imbalance is necessary for understanding and predicting the course of global climate change.
