Asides from causing coral bleaching and other significant problems, warming temperatures also deplete oxygen from the ocean. Marine organisms cannot navigate through large parts of the ocean that have become oxygen-depleted, losing access to their prey as well as mating opportunities and shelter. This distressing pattern is a direct effect of global warming.
