Scientists say the sea levels are rising and will continue to do so indefinitely. Coastal communities around the world are already feeling the impact of the rising waters. Many cities and towns are adapting to this new reality. Their response has been photographed and is being presented at an exhibit called Sink or Swim: Designing for a Sea Change. Meteorologist Dan Cayan with Scripps Institution of Oceanography at the University of California, San Diego, said recent trends will continue. “In the last couple of decades it’s risen at a greater rate. We think very confidently it will accelerate in the next several decades,” said Cayan.
