Ocean life in hot water. Right now, global warming is killing all of the fish living in the sea. Global warning isn't just taking a toll on fish, but it also is allowing the jellyfish to rule. Jellyfish actually thrive in warmer water. Biologist Martin Attrill of the University of Plymouth in England analyzed 50 years worth of data about the North Sea and found out that jellyfish are more prevalent in warm-water years. This is also trouble for the commercial fish. Jellyfish not only out compete fish larvae for food but they eat them too. With the help of satellite data, scientists believe that because of the rising ocean temperature, more phytoplankton are dieing. Phytoplankton forms the base for oceanic food webs. This plant takes in carbon dioxide and breathes out oxygen as much as land plants.
