A new study on the impact of climate change suggests that large numbers of fish species could become extinct in their present tropical home ranges and move and live further northward. Some places in the tropics will become hotspots for extinction as the sea heats up.
The climate models used were the same ones as the Intergovernmental Panel on Climate Change.
They showed that if the Earth’s Oceans warmed by three degrees Centigrade then the fish might move at a rate of up to 26 kilometres in ten years. Even under the best-case scenario, where the Earth's oceans warm by one degree Celsius, fish may move up to 15 kilometres every decade.
The tropics will be the overall losers as many species of fish become extinct in this region. Corals will also continue to die as they bleach in the heat. This is already happening at an alarming rate.
