Fleischmann’s team identified that solar heating, shallow waters, low wind speeds, and high water haziness were the driving factors in the unprecedented temperatures.<\/p>\n
Each of these factors were exacerbated by the others, worsening the quality of life for lake dwellers in a horrifying spiral.<\/p>\n
Turbulent temperatures at Lake Tef\u00e9 which could drop by 20 degrees at night only to swing back up again during the day also caused stress on the wildlife.<\/p>\n
This caused the lake’s fish to die in multitudes, accompanied by the 130 pink dolphins and 23 tucuxi dolphins.<\/p>\n
According to the World Wildlife Fund, pink dolphins still have a population in the ten thousands but were marked vulnerable thanks to contamination of the freshwater they inhabit.<\/p>\n
Tucuxi dolphins symbolize good luck, according to WWF, and are believed to be the guardians of the Amazon rivers.<\/p>\n Fleischmann indicated that the dangerous water temperatures and alarming wildlife deaths were symptoms of climate change.<\/p>\n ‘The climate emergency is here, there is no doubt about it,’ said Fleischmann.<\/p>\n While the study focused on 2023, another unprecedented drought took over the Amazon in 2024.<\/p>\n ‘Ongoing climate change likely will cause more instances like this where temperatures approach or exceed thermal tolerances for aquatic life,’ wrote one of the study’s co-authors Jesse Smith.<\/p>\n As global warming continues to worsen, scientists predict more frequent droughts and far more severe heat waves along the Amazon, likely leading to the loss of even more wildlife.<\/p>\n Fleischmann said that freshwater lakes are crucial to food security for communities around the Amazon.<\/p>\n The ‘overlooked problem’ could affect the livelihood of local communities that were previously thought to be stable.<\/p>\n
