VICTORIA, Seychelles, August 26 (IPS) – Across this vast ocean, the latest monitoring by Mercator Ocean International shows marine heatwave conditions ranging from moderate to severe. At the same time, the World Meteorological Organization expects a strong El Niño to intensify through August to October, with a positive Indian Ocean Dipole also likely to develop. These are not distant scientific signals. They are an urgent warning that the ocean system on which millions depend is under mounting stress.
