In the past few days we’ve had some shocking news on the global extent of coral bleaching.
An extensive aerial and underwater survey of Australia’s Great Barrier Reef (GBR) revealed that 93 per cent of it has been affected, with about half of the reefs severely bleached. Now come reports of widespread bleaching in the Lakshadweep archipelago, which lies 200-440 km off the southwestern coast of mainland India.
Scientists say the bleaching there could only get worse, since May tends to be warmer than April. The threshold for corals before they start bleaching is around 30 degrees Celsius.
In Australia, India and around the world, coral reefs and related ecosystems are under increasing threat from pollution, over-fishing, climate change, and ocean acidification.
