Uncertain about rising seas, developers using mid-range to build up islands

Most of Treasure Island will be inundated by the end of this century, if the documented progression of the ocean’s rise caused by climate change continues as predicted. Studies foresee sea-level rise ranging from as little as five inches to as much as six feet. The lowest parts of Treasure Island lie just four feet above the Bay’s low tide.
