  • Google Gemini Summary: The Lincoln Memorial Reflecting Pool has a documented history of recurring algae blooms since its opening in 1922 due to its shallow depth, warm temperatures, and high nutrient levels from waterfowl.

    The recent $15 million renovation, which included painting the pool dark blue, worsened the issue; the dark color acts as a heat sink, creating a more favorable environment for algae growth.

    The project was executed via two non-competitive, no-bid contracts, including one with a company whose primary experience was with golf course pool maintenance.

    Authorities treated the algae with hydrogen peroxide before formally identifying the species, which risks killing the organism and releasing dangerous toxins if the bloom is actually cyanobacteria.

    This chemical treatment likely caused the new pool liner paint to peel and detach, rather than the “vandalism” by the public that was claimed by officials.

    The death of several birds in and near the water has raised concerns about toxic cyanobacterial blooms, though official investigations are ongoing.

    Technologies like ultrasonic control and nanobubbler systems were deployed, but their effectiveness is severely limited by the pool’s unique, extremely shallow design (only 18 inches deep).

    The government failed to follow professional management standards, such as conducting a proper diagnostic assessment, establishing a nutrient budget, or implementing real-time monitoring.

    Because the pool lacks adequate flushing and circulation—design choices made to maintain its function as a “mirror”—the algae problem is physically unavoidable and cannot be “solved” by cosmetic renovations.

    The expert concludes that the situation is a failure of management rather than a mystery, and suggests that an adaptive management plan is the only professional way to handle the site’s chronic ecological issues.


  • How many words do you require? I wrote, “There’s no climate change.” The Trump admin is well known for considering climate change a hoax. However, this story is what I had in mind when I wrote that sentence, I’m pretty sure it was a Lemmy.world link from the same day, although I do get text-based news elsewhere.

    I also wrote, “Renewable energy plants are too expensive!” Note the exclamation point"!". I often use it instead of a smiley or a sarcasm mark. Sarcasm doesn’t really apply to a truthful observation, such as “I wish it was sarcasm,” and I’m often in a state of indecision in such cases. But perhaps my posting history would explain better? I’m not sure what 35 square miles of photovoltaics would cost, I seem to recall “billions” of dollars being mentioned. What is the cost of some natural gas turbines in comparison?

    Do you suppose if and when Democrats take back power from Republicans, these natural-gas turbines can be legally shut down and renewable-energy plants mandated? Will they be allowed to continue operations instead? Do you suppose that the powers that be will just extract every last barrel of crude they can extract and turn it into CO2?








  • In California, decades ago we used to be able to throw away our household trash in one container. Now we have 3 containers, and it’s recently become a fine-profit center: if folks don’t properly separate their recycling, greenery, and trash components, the AI-surveillance cameras mounted on the trucks will catch it and fine the subscriber (never mind that these trash-recycling-greenery containers are unlocked and on the street where anyone can open and toss something in). In similar fashion, if society adopts robots for household chores, how long until household inspections are held to fine people (as a profit center) who don’t keep their homes sufficiently neat?



  • Off-topic comment. I read this article, but read it in a couple different sessions due to interruptions, and had apparently clicked on to other pages. I wanted to comment about how US culture is unreasonably hard on young people (in general), and for all the US talk of freedom, is often restrictive, especially so for minors. Unfortunately, finding this article page was rather difficult. A browser addon called “What we say” had 4 links from the article back to Lemmy discussion, but they were mostly to a federated instance called “Division by zero”. So I tried the button labeled “Find in my home instance”, but it refused to work, which could be due to my own browser’s configuration (it has worked on other articles and instances). So I came back to lemmy.world, and had to scroll manually through several pages, using browser search to find the article. It’d be nice if there was a more direct method of finding a Lemmy discussion from a non-Lemmy webpage.
