The islands of Hawai'i are peculiarly vulnerable to ocean degree rise. It is believed that 6,500 structures as well as 19,800 people inward Hawai'i could survive exposed to chronic flooding inside the adjacent sixty years. The Hawai'i Sea Level Rise Viewer has been released to demo which areas of the terra firma volition survive almost affected yesteryear rising ocean levels.
The map allows users to come across which areas could survive exposed to coastal hazards from ocean degree rise, modelling the trial of passive flooding (still H2O high tide flooding), annual high moving ridge flooding (over launder during the largest moving ridge events of the year), as well as coastal erosion. The map models ocean degree ascension for 4 dissimilar ocean degree ascension scenarios (these are ocean degree rises of 0.5 ft, 1.1 ft, 2 ft or 3.2 ft).
The Sea Level Viewer besides includes 2 layers which model the economical loss that could termination from rising seas as well as the possible impact of flooded highways. 38 miles of coastal roads inward the terra firma are vulnerable to rising ocean degree rises. If these larn chronically flooded as well as impassible as well as then access to many communities would larn much to a greater extent than difficult. The economical loss layer visualizes the possible terms from terra firma as well as structures beingness flooded inward the mapped area.
The Hawai'i Sea Level Rise Viewer uses global ocean degree ascension projections from the UN. This model predicts seas could ascension yesteryear every bit much every bit 3.2 feet yesteryear the twelvemonth 2100. More recent models propose that a ascension of three feet or to a greater extent than could hand off every bit early on every bit 2060.
