During the last week, a tragic event occurred in the Brazilian Amazon, where more than one hundred lifeless dolphins were found in Lake Tefé. According to CNN, this disturbing incident occurred during an unprecedented drought, with extreme water temperatures in some areas reaching more than 102 degrees Fahrenheit (39 degrees Celsius).
The Mamiraua Institute, a research institution supported by the Brazilian Ministry of Science, reported this alarming discovery.
According to the institute, the unusually high number of dolphin deaths is a cause for great concern, as mentioned in the outlet’s report.
This worrying situation is likely to exacerbate the concerns of climate scientists, who are increasingly concerned about the consequences of human activities and severe droughts in this ecologically important area.

“It is still early to determine the cause of this extreme phenomenon, but according to our experts, it is undoubtedly related to the period of drought and high temperatures in Lake Tefé, in which some points exceed 39 degrees Celsius,” he added.NN cited the Brazilian institute.
Extreme weather conditions have reduced water levels in the Amazon, which is home to the world’s largest rainforest, covering more than 5.5 million square kilometers, about the size of Australia.
The current drought is affecting around 100,000 people in the area.
While some sections of the river still allow boat navigation despite significantly reduced water levels, the Brazilian government is establishing a task force to help those who rely on the river to transport essential goods such as food and supplies.
CNN further said that experts are trying to relocate surviving dolphins from lagoons and ponds to the main river, where the water is colder.
“But some environmentalists have expressed concern. Transferring river dolphins to other rivers is not so safe because it is important to check whether toxins or viruses are present before releasing the animals into the wild,” said André Coelho, a researcher at the Mamiraua Institute. exit.
Reduced water levels have been observed in 59 municipalities in the state of Amazonas.
