Nicholas A. J. Graham from School of Marine Science & Technology, Newcastle University, Newcastle-upon-Tyne, United Kingdom and his other associates from different institutes studying the impact of increasing temperature on coral reef and its dependent component have documented its effect on the coral lives and have sent an alert to the regional authority to take further steps to curb the degrading ecosystem.
Change in hard coral cover across the region between the mid 1990s and 2005 varied geographically. The changes reported represent the combined effects of coral loss in 1998 and any subsequent recovery to 2005. The greatest declines were apparent through the low latitude island states of Maldives, Chagos, and Seychelles. Kenyan and Tanzanian nationally protected sites experienced moderate declines, while Mauritius and Réunion sustained the smallest declines, and coral cover increased in Kenyan and Tanzanian fished sites.
