Climate Change May Force Fish to Relocate to Poles, Study

By Stephen Adkins

A new University of British Columbia study claims that a large number of fish will vanish from the tropics by 2050.

The researchers analysed the influence of climate change on 802 commercially important species of fish and invertebrates. They found that varying temperatures will drive more marine fish and invertebrates into the Arctic and Antarctic waters.

For example, if the Earth's oceans warm by three degrees Celsius by 2100, fish could relocate from their current habitats at a rate of 26 kilometres per decade. And if the Earth oceans warm by one degree Celsius, fish would move 15 kilometres every decade.
