Discover the ‘Where, When, and How Much?’ of the Rising Seas

Published on Jun 19, 2022

Dr. Benjamin Hamlington, a Research Scientist in the Sea Level and Ice Group at NASA’S Jet Propulsion Laboratory in Pasadena, will be speaking about sea level rise in an event sponsored by the Altadena Library District on Tuesday, June 21, starting at 6:30 p.m.

The event, “Rising Seas: Where, When and How Much?” will be held at the Altadena Main Library’s Community Room, and is free and open to the public.

Scientific studies show that sea level rise is a direct consequence of climate change and global warming. With measurements from satellites and other systems here on Earth, the understanding of sea level rise and the drivers behind it has progressed in recent decades. This has led to a clearer picture of where sea levels are changing, how fast they are changing, and how much they have already changed.

In this presentation, Dr. Hamlington will provide a brief overview of the science behind rising sea levels, leading into a discussion of the future of sea level rise.

Dr. Hamlington studies the ocean with a particular focus on sea level variability on interannual to decadal timescales. He has also done considerable work on understanding sea level during the 20th century, comparing historical in situ data to modern satellite observations. He is interested in how sea level responds to both natural and anthropogenic forcing, and what this will mean for coastal populations both now and in the future.

Hamlington is a member of NASA’s Ocean Surface Topography Science team, NASA’s GRACE/GRACE-FO (Gravity Recovery and Climate Experiment and GRACE Follow-On) Science Team and is the current team lead of the NASA Sea Level Change Science team.
