    #Fossils reveal ‘latitudinal traps’ that increased #extinction risk for marine species

    Animals living on convoluted or east-west orientated #coastlines (such as those found in the Mediterranean and Gulf of Mexico today) were more likely to go extinct than those living on north-south orientated coastlines.

  3. Ocean spray emits more PFAS than industrial polluters, study finds

    Ocean waves crashing on the world’s shores emit more PFAS into the air than the world’s industrial polluters, new research has found, raising concerns about environmental contamination and human exposure along coastlines.

    The study measured levels of PFAS released from the bubbles that burst when waves crash, spraying aerosols into the air.

    It found sea spray levels were hundreds of thousands times higher than levels in the water.

    The contaminated spray likely affects groundwater, surface water, vegetation, and agricultural products near coastlines that are far from industrial sources of PFAS, said Ian Cousins, a Stockholm University researcher and the study’s lead author.

    “There is evidence that the ocean can be an important source [of PFAS air emissions],” Cousins said.
    “It is definitely impacting the coastline.”

    PFAS are a class of 15,000 chemicals used across dozens of industries to make products resistant to water, stains and heat.

    Though the compounds are highly effective, they are also linked to cancer, kidney disease, birth defects, decreased immunity, liver problems and a range of other serious diseases.

    They are dubbed “forever chemicals” because they do not naturally break down and are highly mobile once in the environment, so they continuously move through the ground, water and air.

    PFAS have been detected in all corners of the globe, from penguin eggs in Antarctica to polar bears in the Arctic.

    EPA has limited six ‘forever chemicals’ in drinking water – but there are 15,000

  4. Planning for cities with linear skylines

    Shown below are some of the cities around the globe that have linear skylines. While these can be visually impressive, especially when set as a backdrop against the coastline or mountains, they also can be challenging from a planning and infrastructure perspective, unless they are adapted properly to address this unique urban landform.

    Bear in mind, that linear skylines are not just a coastal or narrow valley phenomenon. Las Vegas is perfect example of an inland city with a very linear skyline that resulted in part due to how the city developed as a desert oasis along a single major corridor. Other examples may result from topographic settings like narrow mountain valleys, river valleys, peninsulas, or islands.

    The length of linear skylines can tend to dissuade walking, as the distances between sites can be intimidating. Furthermore, if the focus is too concentrated, primary streets that run the length of the skyline, such as the Las Vegas Strip, can become overwhelmed by traffic and people.

    That is why it is important to have viable and efficient alternatives — light rail, buses, bicycling routes, trollies, or as Las Vegas has developed, a monorail line. Safe crossings of busy thoroughfares is also needed. As the image are shows, overpasses or tunnels for pedestrians may be necessary. Otherwise, crosswalks must be set up to allow time for safe movement across the avenues.

    In some ways, a linear design can be efficient when it comes to utilities, because they can be focused in a narrower area. However, they must constructed of sufficient size and scale to handle the concentrated needs for water, sewer, electricity, gas, etc. Otherwise, the streets and roads may be constantly torn up to increase capacity. Utility managers will also need to address verticality of the service area, to assure water pressure and other services are maintained at their highest levels.

    Another important factor to consider is public safety, particularly from fire-fighting and emergency response standpoints. By their very nature, linear skylines tend to be more dense and as a result taller. This is very evident from the photos provided below. How public safety services address the inherently denser and taller structures is critically important for assuring public safety is always a top priority for avoiding potential tragedies.

    Another factor to consider for tourist-oriented linear skyline is the variations between on and off-season. Any and all planning efforts will need to take this into account as the extent of impacts can fluctuate greatly over a calendar year.

    What is likely to be the most linear (and perhaps vertical) skyline of them all is the controversial 106 mile long, new city of Neom being constructed in Saudi Arabia (see images above and below. How this project will eventually turn out and whether it will achieve the stated goals of livability and sustainability remains to be seen. If it is successful, it may be a defining development for the future. Otherwise, it could be a precautionary tale to avoid excepting very specialized circumstances.

    As has been noted throughout this post, linear skylines can have their challenges. How effectively these are addressed will help determine whether or not the infrastructure and services can meet the concentrated demand. At the same time, the opportunities are not quite as apparent. To this retired planner, ambitious individual developments that are overly lengthy or excessively vertical may not achieve their “lofty” goals. Similarly, it remains to be seen how efficient and effective such a narrow, dense and lengthy urban form can be.

    Peace!

  5. The #Corals That Survive #ClimateChange Will Be Unrecognizable

    They have endured so much, and to endure this, they’ll have to adapt dramatically.

    By Marina Koren
    August 28, 2024

    "Earth belonged to the corals first. And over hundreds of millions of years, they proved themselves remarkably good at adapting to each new version of the planet. As other groups of organisms dropped out of existence, corals endured so many catastrophes that their history reads like a biblical tale of resilience. Through #extinctions mass and minor, through #volcanic eruptions #and asteroid strikes, the corals survived.

    "And for tiny marine animals, they managed to exert tremendous force on the planet’s landscape. Corals have raised whole islands into existence. They are the natural guardians of #coastlines; they sustain an estimated quarter of known #MarineLife. If the reefs ringing the #Maldives die, an entire nation could erode into the sea. Humans live in these places because corals exist.

    "The Earth that humans evolved on, in other words, is a coral planet. Today, the animals provide #ecosystems that support the livelihoods of about 1 billion people. They are so fundamental to life as we know it that scientists wonder if one way humanity could discover alien life is by detecting the signature of fluorescent corals in the shallow waters of another planet. Corals are also, famously, being devastated by climate change. Even in a future where they survive in some form, their transformation could make our own experience of this planet profoundly different.

    "The earliest corals emerged about 500 million years ago, roughly alongside plant life on land. But the modern version of coral reefs appeared a short 4 million years ago, around the time our human ancestors began to walk upright (give or take a few million years). When researchers try to rescue suffering corals, carefully cutting pieces away and transporting them to aquariums, they’re visiting underwater metropolises that are thousands of years old. Despite all that corals have been through, given how fast conditions on Earth are changing, life has likely never been quite as stressful for them as it is now, according to the coral experts Bertrand Martin-Garin and Lucien Montaggioni in their book, Corals and Reefs.

    "Earlier this month, scientists reported that #Australia’s #GreatBarrierReef is sitting in water that, in one decade, has become hotter than at any other point in the past 400 years. #Caribbean coral colonies are still reeling from the havoc of last year’s historic #MarineHeatWave. Around the world, extraordinarily hot ocean temperatures have plunged corals into one of the worst #CoralBleaching events in recorded history—they’re expelling the #algae that live in their tissues and turning a ghostly white. Corals can survive bleaching, if conditions improve. But the longer they remain without that algae, the more likely they are to die.

    "'These are strange days on planet Earth,' Derek Manzello, a coral-reef ecologist and the coordinator of the National Oceanic and Atmospheric Administration’s Coral Reef Watch, once told me. The planet used to give corals hundreds of thousands of years to adjust to a new reality; #HumanActivities—the burning of #FossilFuels but also #overfishing and #pollution that have brought on #GlobalWarming—have introduced a rate of change more dramatic than anything else in the geological record. “If we wanted to kill all reef-building corals on the planet, it would be hard to imagine a collection of activities quite as pointed and effective as what we’ve arrived at,' Stuart Sandin, a marine biologist at the Scripps Institution of Oceanography, told me."

  7. Diggers Beach is located in #Coffs Coast Regional Park. Masked lapwings patrol the surfline. White-faced Herons pick their way through the dunes and White breasted sea eagles soar over the beach. The flowering coastal banksias are overpowered with flocks of Lorikeets.The Horsetail Casuarinas are rich with seeds for the Glossy Black #Cockatoos.
    The beach is supposed to be dog free, as dogs are not permitted in National Parks and Nature Reserves. Locals regularly set their pets free on this beach. Like all other NSW beaches there is never any enforcement.

    The beach is buffered by a thin strip of native vegetation separating it from the many car parks and picnic areas behind it. The official beach access is via two #ViewingPlatforms. The two major #loookouts have been constructed to lead motorists to these platforms so they can see. Every few meters impatient people/ motorists have trailblazed numerous extra trails to the beach and bush in between the designated viewing platforms. Each newly made trail slowly erodes. The mostly native vegetation scaffolding the dunes from ocean storms is eroding. Large banksias and huge pandanus topple down the dunes.
    Additionally, the absence of effective #ClimateAction increases the #CoastalErosion damage. The tourist infrastructure collapses. The constructions crumble like cardboard and the foundational pillars are exposed and washed down the beach. Various anthropogenic rubble is then sloshed along the beach.
