The study, lead by researchers at Georgia Tech, uncovers how weakening prehistoric ocean currents impacted North Atlantic nutrient levels and ocean life, supporting predictions about how today's oceans might react to a changing climate.
Members of the College of Sciences community gathered at Harrison Square on May 8 to recognize outstanding faculty and staff as part of the 2023-2024 academic year Spring Sciences Celebration.
Georgia Tech researcher investigates how rainfall will change as Earth’s atmosphere heats up.
This semester, 33 faculty members from across the Institute were awarded tenure. Tenure recognizes a faculty member’s contributions to Georgia Tech through research, teaching, and community.
Estimating fire emissions prior to the satellite era is challenging because observations are limited, leading to large uncertainties in the calculated aerosol climate forcing following the preindustrial era. This challenge further limits the ability of climate models to accurately project future climate change. In this study, researchers reconstruct a gridded dataset of global biomass burning emissions from 1750 to 2010 using inverse analysis that leveraged a global array of 31 ice core records of black carbon deposition fluxes, two different historical emission inventories as a priori estimates, and emission-deposition sensitivities simulated by the atmospheric chemical transport model GEOS-Chem. The study’s researchers include Bingqing Zhang, Takamitsu Ito, and Pengfei Liu of the School of Earth and Atmospheric Sciences.

April 30, 2024It’s possible for volcanoes to have a short-term impact on the climate – including global temperature cooling – due to the gases they inject high into the upper atmosphere. But Mount Ruang’s influence on the climate will likely be minimal, according to Greg Huey, professor and chair of the School of Earth and Atmospheric Sciences. And the day-to-day weather conditions near Mount Ruang in Indonesia – things like temperature, clouds and rain – probably won’t be influenced by the volcano for long, Huey told CNN. “The ash itself is short-lived in the atmosphere because it’s heavy, it’s big and it tends to settle out quickly,” Huey told CNN. It’s the gases that are able to reach much higher in the atmosphere. (This story also appeared at WRAL.)

April 23, 2024"A dog is a man's best friend," the old saying goes. Can the same soon be said of robot dogs? This summer, a group of scientists including alumna Feifei Qian (M.S. PHYS 2011, Ph.D. ECE 2015) and School of Earth and Atmospheric Sciences assistant professor Frances Rivera-Hernández, will travel to Oregon's snow-capped Mt. Hood to train a dog-shaped robot named Spirit how to walk. The slopes of Mt. Hood are strewn with volcanic rocks and sprinkled with glaciers, a rugged environment that researchers think resembles the moon — which Spirit is being prepared to eventually explore.
