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.

    We don’t have too many more years before this is common throughout the globe. Remember that this is a canary in a coal mine, or the first domino to fall. It is not going to stay exclusive to this lake, this country, or this hemisphere.

    I’ve gone through the stages of grief when it comes to climate change more than I’d like to admit. I wished the evidence I saw was wrong. I hoped the predictions were incorrect. Yet here we are, watching river dolphins boil alive and people saying, “huh, that’s weird. I wonder why that happened.”

        Anger subsided all the other emotions for me as far as climate change. There were people who knew. There’s something along the order of magnitude of 100 people who chose to obfuscate science and sacrifice us all for profit. I hate those people. I can’t even feel sad because I hate them so much.

      I can’t stand more than a half hour in a jacuzzi and that’s in an air-conditioned room. I know that we’re in an extinction event and I shouldn’t be so attached to our living species, but my heart hurts to hear this news.

            Like, less alcohol required?

            Man I’m gonna need a jacuzzi. It takes a phenomenal amount of alcohol to get me drunk and I’d like it to be cheaper

              It’s also dangerous because the hot water causes vasodilation, and combined with alcohol it’s much easier to get light headed and pass out or otherwise injure yourself. Many people die this way. Also shouldn’t have sex in the hot tub, and there’s a whole list of reasons for that which I will let you research on your own.

                Ah okay, I’ll do my drinking after the hot tub then. Or instead of it since I don’t even own one
