The frequency of natural disasters has soared in recent decades. Total damage topped $210 billion worldwide in 2020. With climate change, the costs attributed to coastal storms will increase dramatically.
At the same time, coastal habitats such as wetlands and reefs are being lost rapidly. Some 20% of the world’s mangroves were lost over the last four decades. More than half of the Great Barrier Reef was degraded by bleaching in 2020 alone. In California, we have lost more than 90% of our coastal marshes.
