Image of the Day: Fish Feel the Heat of Global Warming

A new study from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) says that tropical fish in Australia are dying off or moving south due to climate change. The Climate Adaptation Marine Report Card 2012 recently released shows evidence of large-scale migration of marine life throughout the continent. The report described southeast Australia as a “global warming hotspot.” And while some marine life does adapt to warmer waters, others that migrate are now in contact with others that they weren’t before. The concern then is about the food chain as different species come together for the first time. For example, sea urchins normally found north of Bass Strait are starting to eat Tasmanian kelp forests, which provide habitat for many fish species. Dr. Elvira Poloczanska, who led the study, believes there is a great amount of uncertainty about the long-term impacts.
