Salt marshes, which form a natural defence against the impact of climate change, could disappear before the end of the century, scientists have warned.
A study into coastal vegetation predicts warmer temperatures will encourage the plants to grow until around 2075, but a simultaneous rise in sea levels means they are likely to drown by the year 2100. Researchers said salt marshes are effective at removing carbon dioxide from the air and lock away as much carbon as about one-third of the world's forests.
