College of Sciences

Susan 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. 

Comet Lulin, a rare green comet discovered in 2007, is set to make its closest approach to the Earth around Feb. 24. The comet's green color comes from the gases that make up its atmosphere. Its closest approach to Earth will be 38 million miles. James Sowell, principal academic professional in the School of Physics and director of the Georgia Tech Observatory, joins Atlanta News First to talk about the best times to view the comet, where it may have originated, and how rare green comets are in the universe.
