I recently went to visit Plymouth Rock. I have ancestors that came over on the Mayflower. It was a fun trip. I also noticed that the plymouth rock at high tide wasn't under water. Heck the water barely touches the base of it. So if there is a warming and melting of ice caps, shouldn't the sea also be rising? I read about this all the time yet here is this rock, circa like 1620 or so, and it's not underwater at high tide (it was a king tide too). The water barely touched the base of it. Locals said it's been like that for as long as they can remember for generations.
