With Floods Getting Worse, Miami Might Build a 20-Foot Sea Wall

Climate change is worsening flooding in Florida including the city of Miami, and now there are talks to build a 20-foot high sea wall to protect the city. The proposal comes after more frequent floods, says NBC Miami meteorologist Angie Lassman. Even "sunny day floods" also known as high tide floods are increasing, happening 4 times as often now compared to 15 years ago.
