I believe most of this island is safe even if the Antarctic ice sheets melt. As I remember the estimate is that world sea levels would go up 20 to 30 feet if that happened. Most of this island is higher than that. The land slopes gently up from the water for a way and then runs up into a cliff line that varies from 50 to 200 feet high. We'd probably end up as two islands with the center swamped at high tide but I can easily find a house lot that is out of reach of the water. Right now I live at quite a high elevation up in the hills. Of course the office would be gone but who cares about that!
