Susan Lozier Appointed to Climate Security Roundtable

By Jess Hunt-Ralston

At the direction of Congress, the National Academies of Sciences, Engineering, and Medicine is establishing a Climate Security Roundtable convening experts from academia, the private sector, and civil society to provide support to the Climate Security Advisory Council (CSAC).

CSAC is a joint partnership between the U.S. Intelligence Community and the Federal Science Community and seeks to better understand and anticipate the ways climate change affects U.S. national security interests.

The new Climate Security Roundtable will support CSAC in anticipating, preparing, and ultimately preventing climate security crises from escalating into national security challenges and threats.

Susan Lozier, dean and Betsy Middleton and John Clark Sutherland Chair of the College of Sciences at Georgia Tech, will serve a three-year term on the Roundtable.

OSNAP and Earth’s Heat Pump: The Ocean Conveyor Belt

By Allison Shirreffs

The ocean covers more than 70% of the Earth and operates in a state of equilibrium with the atmosphere to regulate climate and CO2 levels. As a result, dynamics that affect the uptake of CO2 across the ocean surface affect global atmospheric temperatures.

Lozier, who ( in addition to her duties as dean and AGU president ) studies ocean circulation and the impact of ocean physics on marine ecosystems, is currently leading the NSF-funded project OSNAP, the Overturning in the Subpolar North Atlantic Program. OSNAP is an international observing network with a necklace of ocean instruments — strung from Canada to Greenland to Scotland — measuring what’s commonly known as “the ocean conveyor belt,” explains Lozier. “The overturning circulation is a huge current system that drives regional and global climate.

“What happens if the overturning circulation slows down because the waters of the surface warm — or if they get fresher because there’s more glacial melt?” Lozier asks. “If the ocean doesn’t take up as much CO2, that’s a good news, bad news story.” Good news because less CO2 in the water means fewer adverse effects, such as ocean acidification, but bad news because more CO2 stays in the atmosphere.

Lozier Elected to American Academy of Arts and Sciences

College of Sciences Dean Susan Lozier has been elected a member of the American Academy of Arts and Sciences.

Susan Lozier, dean and the Betsy Middleton and John Clark Sutherland Chair in the College of Sciences, has been elected a member of the American Academy of Arts and Sciences. She is among 276 artists, scholars, scientists, and leaders in the public, non-profit, and private sectors who will be inducted Oct. 9-11.

The Academy was founded in 1780 by John Adams, John Hancock, and others to honor exceptionally accomplished individuals and engage them in advancing the public good. Lozier, an expert in physical oceanography with an interest in large-scale ocean circulation, is being recognized for decades of extraordinary work.

“It’s incredibly humbling to be recognized by members of this arts and sciences community, given its rich history,” Lozier said. “I have always balked at the myth that science is the journey of a lone individual as I have enjoyed working with students, postdocs, and colleagues over the years and have gained immeasurably from those interactions. Since I view science as a community effort, building on the work that others have done and laying the foundation for the future, being recognized by the community is particularly gratifying.”

Conversation With Cabrera

Unscripted and informal — unearthing leadership’s thinking behind the big ideas taking shape across the Institute — this new video series is meant to capture candid conversations between President Ángel Cabrera and other Georgia Tech leaders.

In this first installment, President Cabrera chats with Susan Lozier, the new dean of the College of Sciences. They not only share the same start date at Tech (Sept. 3, 2019), they also point to the same campus event as one of their most treasured highlights since then.
