DOLPHIN SKIN DISEASE TIED INTO CLIMATE CHANGE

PHYS ORG : DOLPHIN SKIN DISEASE - 70 % OF BODY - GLOBAL WARMING 

EXCERPT :  ... it is the first time since the disease first appeared in 2005 that scientists have been able to link a cause to the condition that affects coastal dolphin communities worldwide.  Due to the decreased water salinity brought upon by climate change, the dolphins develop patchy and raised skin lesions across their bodies - sometimes covering upwards of 7% of their skin.

.... This study comes on the heels of significant outbreaks in Louisiana, Mississippi, Alabama, Florida and Texas and Australia in recent years.  In all of these locations, a sudden and drastic decrease in salinity in the waters was the common factor.  Coastal dolphins are accustomed to seasonal changes in salinity levels in their marine habitat, but they do not live in freshwater.  The increasing severity and frequency of storm events like hurricanes and cyclones, particularly if they are preceded by drought conditions, are dumping unusual volumes of rain that turn coastal waters to freshwater.
