Rising ocean temperatures are rearranging the biological make-up of our oceans, pushing species towards the poles by 7kms every year, as they chase the climates they can survive in, according to new research.

The study, conducted by a working group of scientists from 17 different institutions, gathered data from seven different countries and found the warming oceans are causing marine species to alter their breeding, feeding and migration patterns.

Surprisingly, land species are shifting at a rate of less than 1km a year in comparison, even though land surface temperatures are rising at a much faster rate than those in the ocean.

“In general, the air is warming faster than the ocean because the air has greater capacity to absorb temperature. So we expected to see more rapid response on land than in the ocean. But we sort of found the inverse,” said study researcher Dr Christopher Brown, post-doctoral research fellow at the University of Queensland’s Global Change Institute.
