A study by University of British Columbia researchers have found that the world’s fish have been steadily moving to cooler waters. What is worrying is that these are no temporary vacations, but permanent adjustments.
According to the Washington Post, scientists used data collected from 968 fish species and invertebrates over a span of three decades, confirming that the change is happening on a global scale.
“One way for marine animals to respond to ocean warming is by moving to cooler regions,” said William Cheung, the study’s lead author. “As a result, places like New England on the northeast coast of the U.S. saw new species typically found in warmer waters, closer to the tropics. Meanwhile in the tropics, climate change meant fewer marine species and reduced catches, with serious implications for food security.”
