A research published in Scientific Reports shows that dolphins are developing a fatal skin disease linked to the climate crisis. The study shows that the condition is related to the drop of salinity of coastal waters caused by the more frequent and intense storms. The world’s largest marine mammal hospital in Sausalito, California conducted the research alongside Australian researchers and it it is the first time scientists have been able to attribute a cause to the condition.
Known as ‘freshwater skin disease’, it appeared 15 years ago in bottlenose dolphins and subsequently discovered in marine mammals in different parts of the world. The disease has been killing dolphins since Hurricane Katrina. After 2020 became the year to break the record for the number of Atlantic storms strong enough to be given names in a single season, dramatic drops in saltiness, which link to the disease, becomes more common.
