The death of hundreds of dolphins due to record-breaking 41-degree waters in the Amazon: "It was so hot they had nowhere to take refuge."

Research documents the extreme temperatures of Amazonian lakes during the historic 2023 drought, which affected aquatic species and isolated riverside communities. The warming of aquatic ecosystems is occurring across the planet, and the Amazon has not escaped this process. The lakes and rivers of the world's largest rainforest have reached unprecedented temperatures in recent years, demonstrating the global warming that is changing the tropics. Research published this Thursday in the journal Science indicates that a drought and an extreme heat wave in 2023 caused water temperatures to reach unprecedented levels: up to 41 degrees Celsius. This warming particularly affected marine species and the survival of riverside communities that depend on water for their livelihoods.
