More than a hundred dolphins have been found dead in the Brazilian Amazon amid an historic drought and record-high water temperatures that in places have exceeded 102 degrees Fahrenheit.
The dead dolphins were all found in Lake Tefé over the past seven days, according to the Mamirauá Institute, a research facility funded by the Brazilian Ministry of Science.
The institute said such a high number of deaths was unusual and suggested record-high lake temperatures and an historic drought in the Amazon may have been the cause.
The news is likely to add to the concerns of climate scientists over the effects human activity and extreme droughts are having on the region.
“It’s still early to determine the cause of this extreme event but according to our experts, it is certainly connected to the drought period and high temperatures in Lake Tefé, in which some points are exceeding 39 degrees Celsius (102 degrees Fahrenheit),” the institute said in comments carried by CNN affiliate CNN Brasil.
The Amazon River, the world’s largest waterway, is currently in the dry season, and several specimens of river fauna are also suffering from record-high temperatures.
