Sea levels across the United States are increasing, especially in the Southeast. In fact, they are rising at an accelerating rate, which is leading to concerns about how coastal communities will deal with the higher water levels in the future. The rise is due to a number of causes, including groundwater withdrawals, changes in the atmospheric circulation over the Atlantic Ocean, and thermal expansion of water due to warming ocean waters from rising temperatures. You can read more about the current observations and how South Florida is responding at Physics Today here and Newsweek here. An interactive map of coastal elevations and how climate change would affect sea water elevation is available at
