This lecture will be held at the Hyatt Regency Pier Sixty-Six, 2301 S.E. 17th Street, Fort Lauderdale, FL (see below for directions) and will serve as the opening talk for the 3rd Sea-Level Rise Summit: Connected Futures from Alaska to Florida
Global mean sea level is rising in response to two primary factors: warming oceans and diminishing glaciers and ice sheets. If melted completely, glaciers would raise sea levels by half a meter, much less than that the 80 meters or so that would result from total melt of the massive Greenland and Antarctic ice sheets. That is why glacier contributions to sea level rise have been less studied, allowing estimates to vary widely. Recent advances in satellite altimetry and gravimetry now allow for precise estimation of global glacier contributions to sea level rise. Using these new techniques glacier loss was found to account for 30% of global mean sea level rise over the 2003-2014 period, an amount equal to the contribution from both ice sheets combined. Over the next century and beyond glaciers are expected to continue to contribute substantial volumes of water to the world’s oceans, motivating continued study of how glaciers will respond to future changes in climate.

Alex Gardner is a Research Scientist at Caltech’s Jet Propulsion Laboratory. He earned a B.Eng. in Civil Engineering from the University of Saskatchewan, a Ph.D. in Earth Sciences from the University of Alberta and was a NSERC research fellow in the Department of Atmospheric, Oceanic, and Space Sciences at the University of Michigan. He is a member of NASA’s Sea Level Change and ICESat-2 Science Definition Teams. Alex studies the Earth’s cryosphere (frozen Earth) with a particular focus on glaciers and their impacts on sea level rise and water resources. He is interested in how glaciers respond to natural and human induced forcings as well as how changes in the reflectivity of snow and ice modify the Earth’s climate.
To get to the Hyatt Regency Pier Sixty-Six, take the Turnpike or I-95 to I-595 East. Head east on I-595 and follow the signs for the US-1 North exit (Federal Hwy. N). Stay on US-1 North and proceed to the 17th Street Causeway, turn right to head East. As soon as you go over the waterway bridge, the Hyatt will be on the left at the base of the east side of the bridge.
Parking - When you arrive at the Hyatt, go through the self parking gate and take a ticket. When you leave, tell the parking attendant that you were there for the FAU Events and you parking will be free. Valet parking is available but is not covered by FAU.
