After living in coastal Virginia and seeing the effects of climate change firsthand, Ben Hamlington is now researching sea level rise at NASA JPL.

The Legacy of Topex/Poseidon

It’s not only water processes that play a role in global sea level rise – ground movements can play a significant role as well.

In many communities in the U.S., sea level rise is already a factor in people’s lives in the form of high-tide flooding.

Jason-1 Fact Sheet

Earth’s global sea levels are rising – and are doing so at an accelerating rate.

This visualization shows total sea level change between 1992 and 2019, based on data collected from the TOPEX/Poseidon, Jason-1, Jason-2, and Jason-3 satellites. Blue regions are where sea level ha...
