Anthropogenic Warming of Oceans Driving Marine Species from Tropics towards Poles

The tropical water at the equator is renowned for having the richest diversity of marine life on Earth, with vibrant coral reefs and large aggregations of tunas, sea turtles, manta rays and whale sharks. However, the ocean around the equator has already become too hot for many species to survive. The global pattern is rapidly changing, and as species flee to cooler water towards the poles, it’s likely to have profound implications for marine ecosystems and human livelihoods. When the same thing happened 252 million years ago, 90 per cent of all marine species died.
