Thursday, May 29, 2025, 6:00-7:15pm – Sea Ice’s Continued Decline

Speaker: Robert Grumbine, PhD, Physical Scientist with NOAA’s National Weather Service, Environmental Modeling Center

About the Talk: Since Bob’s last sea ice presentation at Annapolis Café Scientifique, the Arctic ice pack has continued to thin even though it hasn’t set new records for least ice extent. The Antarctic, on the other hand, has gone from setting record maximum ice extents to record minimum ice extents. With the poles being harbingers of change these both portend changes for points equatorward as well as themselves. We’ll talk about some of those, with polar questions of all sorts being very welcome.

About the Speaker: Robert Grumbine earned a PhD in Geophysical Sciences from the University of Chicago in 1989. After a two-year ocean modeling postdoc at Penn State he started working in the NWS Environmental Modeling Center, where he has been ever since. In that time, his work has included observing sea ice and sea surface temperature, modeling sea ice and coupling it to atmosphere and ocean forecast models and optimizing models by evolutionary methods. Bob earned a Bachelor of Science from Northwestern in School of Engineering in Applied Mathematics, with Astrophysics as the area of application, and modeling continental ice sheets and ice ages for his senior project. 2025 is the 40th anniversary of both graduation and publication of his first paper. In the interim, Bob has coached baseball, juggled on stage in community theater, and run an ultramarathon.
