Climate Change Affecting Ocean Migration

Climate change has drastically reduced the number of blacktip sharks migrating down the Atlantic coast to South Florida, posing a threat to the environmental health of the region.

Researchers at Florida Atlantic University have been tracking what should be an enormous migration, during which sharks leave cooling waters up north and play an important role in the tropical ecosystem. Instead, researchers found a sharp decline in the migrating population.

According to the university, last year’s roving gang was about one-third of what it should have been, and this year’s numbers represent a big drop as well. In the past, shark counters may have caught sight of up to 15,000 sharks in a single day in southern Florida, but the group has not reached that bar in 2018.
