Coral bleaching events
The Seychelles Islands are justly famous for their coral reefs and the remote Aldabra Atoll is the largest raised atoll in the world. Despite its remoteness and protected status, the Seychelles suffered a severe coral bleaching event in the late 1990s and a recent assessment by the Seychelles Foundation judged climate change to be the most significant threat facing the atoll.
In March 2003, WWF reported that coral bleaching was occurring at all its 7 research sites in American Samoa, including within the National Park of American Samoa, Fagatele Bay National Marine Sanctuary and Maloata Bay Community Reserve.
