Their findings proved, tragically, that there is a newly-discovered way in which climate change makes life more difficult for both bull sharks and other undersea life.
Specifically, the study found that climate change is making both more frequent and more intense a phenomenon known as extremely cold upwelling events. Those refer to when pockets of cold water replacer warm water at the surface after being brought there by strong winds and ocean currents. Led by researcher Nicolas Lubitz from James Cook University in Queensland, Australia, the scientists learned that the sharks chose shallower water during upwelling events because they needed to avoid the newly-colder water.
