Atlantic staff writer Katherine J. Wu wanted to find out if she could fix the air quality in her New England apartment. That led her to discover carbon dioxide-monitoring devices with varying degrees of success. Wu turned to climate and air quality experts for some advice, and learned that other pollutants besides CO2, such as carbon monoxide, nitrogen oxide, and ozone, can be even more harmful to health and environments. There's also the matter of, well, particulate matter, and whether the devices pick those up on their monitors. One of the experts Wu consulted is Nga Lee (Sally) Ng, Love Family Professor in the School of Earth and Atmospheric Sciences, the School of Chemical and Biomolecular Engineering, and the School of Civil and Environmental Engineering.

February 3, 2023Susan Lozier, Dean of the College of Sciences, Betsy Middleton and John Clark Sutherland Chair, and a professor in the School of Earth and Atmospheric Sciences, will appear on a panel examining climate change and the Earth's oceans at the 2023 South by Southwest (SXSW) Conference in Austin, Texas, March 10. Lozier, who also serves as president of the American Geophysical Union (AGU), will join leading ocean experts to discuss the ocean’s role in climate, the potential for ocean-based carbon dioxide removal, and a code of conduct for CO2 removal that could maximize collective societal and environmental benefit for our ocean planet.

February 2, 2023The White House has announced that former College of Sciences professor Kim Cobb, currently a professor in Earth, Environmental, and Planetary Sciences at Brown University, has been named to the President's Intelligence Advisory Board. Prior to joining Brown in 2022, she served as director of the Global Change Program at Georgia Tech, professor in the School of Earth and Atmospheric Sciences, and ADVANCE Professor for Diversity, Equity, and Inclusion. Cobb is also director of the Institute at Brown for Environment and Society (IBES).

January 26, 2023Beginning Summer 2023, prospective and current Georgia Tech students will have three new Bachelor of Science degrees to choose from in the School of Earth and Atmospheric Sciences, including one that involves the National Weather Service Forecast Office in Peachtree City as an integral partner in providing practical instruction for students in the B.S. Atmospheric and Ocean Sciences (AOS) Degree. The AOS degree program uses the current Meteorology track as its foundation and will include aspects of Atmospheric Sciences, Oceanography and Climate Sciences. The AOS degree is designed to take advantage of Atlanta as a “hotspot” for major meteorological organizations including The Weather Channel, CNN, local stations in a top 10 TV market, and the National Weather Service (NWS) Peachtree City, Georgia office.

January 24, 2023An unprecedented wave of minor earthquakes focused near Elgin, a small town in Kershaw County in South Carolina, have local residents struggling to describe what they’re experiencing. For a big chunk of 2022, “Did you feel that?” became almost as common a greeting as “How are you?” across the Midlands. The U.S. Geological Survey refers to the Elgin phenomenon as a “swarm.” It began Dec. 27, 2021, with a magnitude 3.3 earthquake. Since then, upward of 80 earthquakes have been recorded. Zhigang Peng, a professor of geophysics in the School of Earth and Atmospheric Sciences, says magma or fluid movement can cause quakes, but scientists haven't found evidence of those with the Elgin swarm.

January 23, 2023Peatlands store a significant amount of the Earth’s carbon and have functioned as an important moderator of carbon dioxide in the atmosphere for thousands of years. But as peatlands are lost to overextraction and affected by a warmer climate, the impact on these natural carbon scrubbers remains unclear. A team of researchers from Florida State University, Georgia Institute of Technology, Oak Ridge National Lab and the University of Arizona received a $3.2 million grant from the U.S. Department of Energy to investigate the status of carbon stored in peatlands, environments that are at risk of carbon release due to climate change. The Georgia Tech researchers include Joel Kostka, professor in the School of Biological Sciences and School of Earth and Atmospheric Sciences; Kostas Konstantinidis, Richard C. Tucker Professor in the School of Civil and Environmental Engineering and the Ocean Science and Engineering interdisciplinary graduate program; and Caitlin Petro, research scientist, and Katherine Duchesneau, doctoral student, both with the School of Biological Sciences. (Here's how the College of Sciences covered this story in October 2022.)

January 19, 2023A research team featuring Georgia Tech scientists has designed an instrument to aid in the analysis of Martian ice cores. The Melter-Sublimator for Ice Science, or MSIS, methodically melts and sublimates ice samples. With humans likely to visit the Red Planet in the coming decades, exploring ice-rich areas like its South Pole, now seems an excellent time to test out the MSIS. The device consists of two separate components, the Melter on top and the Sublimator beneath it. When combined, they allow the controlled initial processing of an ice core or smaller ice fragments, turning a sample ice into either vapor or meltwater, after which specialized tools could be used to perform a detailed analysis, perhaps searching for concentrations of isotopes or the signatures of microorganisms. Chris Carr, assistant professor in the School of Earth and Atmospheric Sciences, is one of the MSIS researchers.

January 14, 2023Ahead of the fifteenth anniversary of the 2008 Iowa Caucuses, President Barack Obama held a roundtable discussion with six former campaign organizers to reflect on their work in Iowa and how, 15 years later, they have continued making an impact within their communities. “I really rode the wave of your work and that ultimately led to a historic election,” said President Obama, who spoke of how seeing campaign organizers and volunteers working so hard up close inspired him to be a better candidate and the role they played in the early victory that put him on a viable path to the presidency. One of those advisors is Shannon Valley, M.S. EAS 2016, Ph.D. EAS 2019. Currently, Valley is a American Association for the Advancement of Science (AAAS) Science and Technology Policy Fellow placed at the U.S. Agency for International Development. Before that, she was a postdoctoral scholar at Woods Hole Oceanographic InstitutioAfAfter n.

January 3, 2023By growing an unusual tentacled microbe in the lab, microbiologists may have taken a big step toward resolving the earliest branches on the tree of life and unraveling one of its great mysteries: how the complex cells that make up the human body — and all plants, animals, and many single-celled organisms — first came to be. Such microbes, called Asgard archaea, have previously been cultured — once — but the advance reported in Nature marks the first time they’ve been grown in high enough concentrations to study their innards in detail. Jennifer Glass, associate professor in the School of Earth and Atmospheric Sciences and a geo-microbiologist, didn't work on the study, but her research in 2020 finding unusual ribosome structures in Asgard microbes helped the scientists published in Nature zero in on what to look for in their specimens.

December 22, 2022Scientists working at the ongoing Department of Energy’s (DOE) Spruce and Peatland Responses Under Changing Environments (SPRUCE) experiment use the site’s northern Minnesota bog as a laboratory. SPRUCE allowed scientists to warm the air and soil by zero to 9 degrees C above ambient temperatures to depths more than 2m below ground. This warming simulates the effects of climate change on the carbon cycle at the whole ecosystem scale over the long term. The research found that the production of the potent greenhouse gas methane increased at a faster rate than carbon dioxide in response to warming. The results indicate that carbon dioxide release and methane production are stimulated by plants‘ release of metabolites, chemicals that plants create for protection and other functions. The scientists included a team from Georgia Tech led by Joel Kostka, professor and associate chair of research for the School of Biological Sciences, with an adjunct appointment in the School of Earth and Atmospheric Sciences.
