When dolphins began washing up dead by the dozens on Lake Tefe in Brazil’s Amazonas state, hydrologist Ayan Fleischmann was sent to find out why.

What he and his colleagues discovered was startling: a brutal drought and extreme heat wave that began in September 2023 had transformed the lake into a steaming cauldron. The lake’s waters reached 41 degrees Celsius, or 105.8 degrees Fahrenheit — hotter than most spa baths.

Their findings, published Thursday in the journal Science, spotlight the impacts of planetary warming on tropical regions and aquatic ecosystems, and come as the United Nations’ COP30 climate talks kick off in Brazil.

    This is my first time hearing that dolphins reside in lakes. Natural inlet.

    Basically, this time, they swam right into a boiling pot.

    We are so royally fucked.

      Scientists have been telling anyone who would listen, for decades, in the most dire terms, of what was going to happen and how badly it’s going to happen and everyone was like “nah they don’t know for sure and they’re exaggerating and being ridiculous” and yet the same people are still going to have the utter gall to act completely surprised pikachu face when it starts actually happening and try to convince us that no one could’ve possibly predicted this.

      except the scientists. who predicted this.

          First off fuck Trey Parker and Matt Stone for their dumb take on it at the time, climate change is real and I agree with An Inconvenient truth for the most part (one lake he highlighted as drying up in the US was actually drained by intensive agriculture wells - everything else accurate). But his biggest failing was setting up a carbon trading company literally at the same time he was telling everyone climate change was real, and that the best measure to deal with it was governments setting up carbon trading.

          Of course as soon as people whom are wary of this huge claim learn that he has a profit motive, then they’re going to suspect he is only trying to line his own pockets.

          All he had to do was spread the message and not be greedy, but he couldnt help himself.

            I think his biggest failing was that the Supreme Court picked Bush as president even though Gore won Florida and thus the election.

      Lived in the Mississippi bayou and in drought conditions ocean water backs up into the lakes and wetlands. I swam with dolphins 30 miles north of the coast some summers.
