Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests that the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species with body plans and metabolisms better suited to the changing conditions survived and went on to dominate the seas, offering a glimpse of how modern marine life could respond to climate change.

If anyone still takes #KrillOilSupplements, please stop! Our friends who live in the ocean need it way more than humans do!
Who's killing Antarctica's ecosystem? The dark side of krill harvesting no one's talking about
by Robbie Lockie
March 5, 2025Excerpt: "Saving Antarctic #krill—and, by extension, Antarctica itself—requires a multi-pronged approach:
- Stronger Quotas: CCAMLR must impose much stricter limits on krill fishing or ban it outright in certain areas.
- Marine Protected Areas: Expanding no-fishing zones in the Southern Ocean is critical to safeguarding krill and the species that depend on them.
- Consumer Action: Shoppers can pressure brands and retailers to stop selling krill-based products. Boycotting krill supplements and pet food sends a clear message to the industry.

Ocean surface temperatures hit record high as world enters 'uncharted territory,' scientists warn
by Chantal Da Silva
July 1, 2026"Temperatures on the #ocean surface hit a record high in June, European scientists warned Wednesday, fueling fears of more dangerous heat waves this summer and fanning concerns over the escalating global #ClimateCrisis.
"Two separate services under the European Union’s #CopernicusEarth observation program — the Copernicus #ClimateChange Service and the Copernicus Marine Service — announced they had both independently confirmed the record temperatures.
"Carlo Buontempo, director of the Copernicus Copernicus Climate Change Service, warned that the rising temperatures could mark the 'beginning of a new phase.'
" 'With OceanTemperatures at these levels and #ElNiño on the horizon, we are likely to see more temperature records fall in the coming months,' Buontempo said in a statement Wednesday. El Niño is a naturally occurring climate cycle that sees the central and eastern tropical Pacific Ocean become warmer than usual for months at a time.
"The world could be heading into 'uncharted territory,' Buontempo warned.
"According to Copernicus Climate Change Service and the Copernicus Marine Service, global ocean temperatures outside the polar regions hit record levels on June 21, surpassing levels for the time of the year observed in both 2023 and 2024.
"The Copernicus Climate Change Service said temperatures reached 20.86 degrees Celsius, or 69.54 degrees Fahrenheit, that day, climbing above the 20.83 degrees Celsius, or 69.49 degrees Fahrenheit observed in 2023 and 2024.
"The Copernicus Marine Service meanwhile recorded temperatures at 21 degrees Celsius, or 69.8 Fahrenheit, beating previous records from 2023 and 2024 by 0.1 degree Celsius.
" 'It’s consistent with what we’ve known for a long time — that the planet is warming because we’re emitting vast quantities of #GreenhouseGasses, primarily from #FossilFuel burning, into the atmosphere and that’s stifling the ability of the planet to lose its heat to space,' Richard Allan, a professor of climate science at the University of Reading in the U.K., said in a phone interview."

😢 A #MarineHeatWave caused seabird deaths off California. El Nino could worsen the die-off
‘We don’t know how bad this is going to get’
By JULIE WATSON
Updated 1:25 PM EDT, July 1, 2026SAN DIEGO (AP) — "Within minutes of walking on a #SanDiego beach, marine ornithologist Tammy Russell found the feathered carcasses — one after another.
Some were mixed in with washed up kelp. Others were under rocks."Each month, scientists and volunteers conduct surveys of dead #seabirds and find what Russell describes as a grim assessment of the impact of a massive marine HeatWave that has lingered for months off parts of the California coast.
"The surveys that have been carried out by various organizations for decades help build a baseline of information on beached sea life to detect threats and their impact.
"Many seabirds, including California #BrownPelicans, #loons and #grebes, starved to death in recent months as record-setting ocean temperatures decreased the band of cold, nutrient-rich surface water where #krill, #anchovies and #sardines thrive near the shore, said Russell, a postdoctoral scholar at the University of California, San Diego, Scripps Institution of Oceanography.
"We’ve been seeing #cormorants walk to shore and then just die within the hour. I mean one time it happened within 15 minutes, and I’ve never seen that before,” Russell said. 'That has been heartbreaking for me and we’re seeing this happening across the whole coast.'
"Scientists fear the die-off could worsen with the recently formed El Nino, the natural warming of parts of the central Pacific that alters weather worldwide and spikes global temperatures."

From #Arctic heat to #megafires, #WMO report shows climate change completely reshaping #Europe
By Andrei Ionescu, 6/2/2026
"In the far north, climate change is not some distant warning anymore. It is already reshaping the landscape.
"Across Alaska and Canada, Arctic and boreal regions are warming up to four times faster than the global average.
"That puts a huge amount of pressure on #ecosystems that have long helped slow climate change by pulling carbon dioxide out of the atmosphere and storing it in #trees, #shrubs, and #soil.
When forests stop helping"The trouble is, those ecosystems do not always stay helpful under stress.
"As wildfires grow more intense, drought becomes more common, and other disturbances spread, parts of the north may start giving #carbon back to the atmosphere instead of locking it away.
"Once that happens, the whole climate system becomes harder to stabilize.
"That is why scientists care so much about #biomass, the total amount of living plant material across these landscapes."

#SeaIce loss in the #Arctic has triggered a critical #TippingPoint that's destroying the food chain
Story by Sascha Pare, June 8, 2026
"The Arctic Ocean has crossed a tipping point that is wreaking havoc on the region's food chain, with potentially dire consequences for commercial fishing and the ocean's capacity to soak up carbon, a new study reports.
"Scientists found that vast areas of melting sea ice in the Arctic are leading to a significant reduction in nitrate, a key nutrient that forms the base of the marine food web and thus underpins important regional fisheries. As the ice disappears, more light hits the water's surface, promoting the growth of microscopic, plant-like organisms called phytoplankton. When phytoplankton die, their cells sink to the seafloor and are decomposed by nitrate- and oxygen-consuming bacteria.
"The new study, published May 28 in the journal Communications Earth & Environment, found that the bacteria are consuming more nitrate than the Arctic ecosystem can withstand.
"This effect, known as 'denitrification,"' is irreversible under current climate conditions because we have passed a threshold where so much sunlight reaches the ocean that it's supercharging phytoplankton's productivity, said Marta Santos-García, a doctoral student of Arctic marine biogeochemistry at the University of Edinburgh in Scotland and the first author of the study.
" 'Even if sea ice were to increase temporarily, the Arctic nutrient system responds over much longer timescales,' Santos-García told Live Science in an email. 'Short-term increases in sea ice would be unlikely to rapidly reverse the decline in nitrate inventories, which may take much longer to recover.'
"Dropping nitrate levels may eventually come back to bite phytoplankton, because these tiny organisms need nitrate to carry out photosynthesis. As a result, the transition to a low-nitrate regime could accelerate #ClimateChange, as nitrate plays an essential role in the ocean's biological pump, which takes #CarbonDioxide from the atmosphere via photosynthesis and locks it away at depth when #phytoplankton and the animals that eat it die.
" 'With nutrients such as nitrate in limited supply this mechanism cannot work effectively,' Santos-García said.
"To understand ecosystem changes in the Arctic, the researchers analyzed two decades of data from the Fram Strait, a passage between Greenland and Svalbard, Norway, that is the main gateway through which Arctic waters flow into the Atlantic Ocean. They found a sharp decline in nitrate levels in this region after 2009, which coincided with a dramatic reduction in Arctic sea ice and a gradual shift in phytoplankton communities toward smaller species that can cope with low nutrient levels.
" 'Shifts towards smaller phytoplankton have already been observed in parts of the Arctic, although these changes have not previously been linked to nitrate losses,' Santos-García said. 'This matters because smaller phytoplankton are generally less efficient at transferring energy up the food web. More of the energy is recycled within microbial communities rather than being passed on to larger zooplankton, fish, seabirds, and marine mammals.'
"Phytoplankton sit at the very bottom of the marine food chain, so the impacts of nitrate depletion will ripple through the Arctic ecosystem, impacting species at the highest levels. This could also affect fisheries in regions that depend on Arctic nutrient exports, such as the North Atlantic. But pinpointing what will happen in ecosystems downstream of the Arctic Ocean requires more research, Santos-García said.
"For years, researchers thought the long-term impact of sea ice loss in the Arctic would be an increase in phytoplankton, because more organisms can bathe in sunlight and multiply when the sea ice extent is small. However, the increase in phytoplankton since 2009 has depleted nitrate levels enough to limit future phytoplankton growth.
"Whereas phytoplankton proliferation used to be limited by how much sunlight reached surface waters, it is now controlled by nitrate levels. Therefore, nitrate must be considered as a key driver of future changes in the Arctic, Santos-García said.
" 'As nitrate is the nutrient that limits Arctic productivity, understanding these changes is therefore important not only for Arctic communities and ecosystems, but also for improving projections of future climate change,' she said."

So, a recurring dream that I had some years ago had involved rotting vegetation underfoot and the smell of hydrogen sulfide. Ummm...
"The hydrogen sulfide gas it releases when it rots is not only stinky but can irritate people's eyes, nose and throat, Florida Health says. The seaweed can also contain jellyfish or sea lice that can irritate skin."

#Algal #Toxins emerge as a new concern in #Alaska’s Northern Bering Sea
Locals who depend on the sea for food and culture are trying to understand the risks to traditional foods and wildlife populations in a region undergoing myriad changes
by Yereth Rosen, Alaska Beacon, May 31, 2026 via #ICTNews
Excerpt: "For countless generations, people of the #BeringStrait region have relied on the food they harvest from the sea without worrying about #HarmfulAlgalBlooms [#HABs] that threaten seafood eaters in warmer and more southern latitudes.
"Now, as the Northern Bering Sea undergoes cascading effects of a warming climate, algal risks pose a new challenge.
"The change has been dramatic.
"And it has prompted a change in the way #Nome youth grow up learning about collecting food from the waters around their home. In early April, Nome high school students traveled to Bethel with their science teacher, where they presented their research at the Western Alaska Interdisciplinary Science Conference held by Alaska Sea Grant.
"Algal toxins were present, at very low but detectable levels, in fish they eat.
"Sophomore Audrey Bruner-Alvanna was among the group of student researchers. She said young people are concerned about algal blooms, which proliferate in warmer conditions, and their potential effects on wild food resources.
" 'Because, you know, as the climate changes, as the world gets warmer and stuff, there’s going to be more of these toxins and stuff during summer,' she said. 'I feel like a lot of people that I’ve talked to have been wondering about how our subsistence is going to change in the future based on all of that.'
"The student research came about after one of the nation’s densest and biggest concentrations of toxin-producing Alexandrium algae ever documented burst forth in the waters of the Bering Strait region in 2022.
"Until the appearance of the 'massive bloom, the most toxic bloom, the longest-persisting bloom in the U.S.,' local people barely knew what harmful algal blooms or #Alexandrium are, said Emma Pate, president of the Nome Eskimo Community, the local tribal government.
" 'So we had to figure things out and learn really fast,' Pate said during an October 'Strait Science' presentation hosted by the University of Alaska Fairbanks’ Nome campus."

‘Only a matter of time’: Warming ocean water will make #FleshEatingBacteria that infected #CapeCod swimmer more common
By Sabrina Shankman Globe
August 15, 2025
"News that a Cape Cod swimmer contracted an infection from a bacteria that can cause a flesh-eating disease earlier this month has stunned many across #Massachusetts, but it was no surprise to David Hamer, an infectious disease expert at Boston University." 'It’s been sort of only a matter of time,' said Hamer, who helps lead work on #ClimateChange and emerging diseases at the university.
"The infection was caused by a #VibrioVulnificus — a bacteria that thrives in warm water and is more commonly found in areas like the Gulf Coast. Other bacteria in the Vibrio family, including those that cause cholera and acute gastroenteritis, similarly thrive in warm water.
"That’s where climate change comes in, making #NewEngland waters friendlier for the potentially deadly bacteria. 'With warmer water temperatures moving further north, it allows Vibrios to survive, during summer months in particular, at higher latitudes than it had previously,' said Hamer.
"And the water is warmer. Midsummer ocean temperatures were about 2.75 degrees warmer in the period from 2021 to 2025 than they were 20 years ago, according to data from an ocean temperature monitor in #WoodsHole, near where the swimmer contracted the virus."

"The infection was caused by a #VibrioVulnificus — a bacteria that thrives in warm water and is more commonly found in areas like the Gulf Coast. Other bacteria in the Vibrio family, including those that cause cholera and acute gastroenteritis, similarly thrive in warm water.
"That’s where climate change comes in, making #NewEngland waters friendlier for the potentially deadly bacteria. 'With warmer water temperatures moving further north, it allows Vibrios to survive, during summer months in particular, at higher latitudes than it had previously,' said Hamer.
"And the water is warmer. Midsummer ocean temperatures were about 2.75 degrees warmer in the period from 2021 to 2025 than they were 20 years ago, according to data from an ocean temperature monitor in #WoodsHole, near where the swimmer contracted the virus."

More victims of #ClimateChange and #WarmingOceans. Also, #KrillHarvesting has got to STOP!
Scientists Alarmed as #Whales Suddenly Going Silent
"When you really break it down, it’s like trying to sing while you're starving."
Aug 1, 10:27 AM EDT by Victor Tangermann
"Researchers are alarmed after noticing a significant drop in the number of vocalizations from #BlueWhales.
"As National Geographic reports, scientists used specialized underwater hydrophones, meaning the aquatic version of microphones, to record and trace the sounds of marine life, allowing them to analyze the impact human activity is having on various species.
"However, as detailed in a study published in the journal PLOS One, devastating heat waves have triggered worrying changes over the past decade, allowing #ToxicAlgae to bloom and undermine food sources for whales.
" 'It caused the most widespread poisoning of marine mammals ever documented,' coauthor and Monterey Bay Aquarium Research Institute biological oceanographer John Ryan told NatGeo. 'These were hard times for whales.'
"As a result, blue whale vocalizations dropped by almost 40 percent, according to the study, with populations of #krill and #anchovy collapsing.
" 'When you really break it down, it’s like trying to sing while you're starving,' Ryan explained. 'They were spending all their time just trying to find food.' "

#Jellyfish Keep Attacking #NuclearPowerPlants
By Gabriel Geiger
November 2, 2021"Jellyfish are continuing to clog the cooling intake pipes of a nuclear power plant in Scotland, which has previously prompted a temporary shutdowns of the plant.
"The #TornessNuclearPowerPlant has reported concerns regarding jellyfish as far back as 2011, when it was forced to shut down for nearly a week—at an estimated cost of $1.5 million a day—because of the free-swimming marine animals.
"In a short comment to Motherboard, #EDFEnergy, which runs the Torness plant, said that 'jellyfish blooms are an occasional issue for our power stations,' but also said that media reports claiming the plant had recently been taken offline because of jellyfish are 'inaccurate.' '[There were] no emergency procedures this or last week related to jellyfish or otherwise,' a spokesperson said. [Um, did they previously work for #TEPCOLies?]
" 'Like many other seaside power plants, the Torness plant uses seawater to prevent overheating. While there are measures in place to prevent aquatic life from entering the intake pipes, according to the #BulletinOfTheAtomicScientists, they are no match for the sheer number of jellyfish that come during so-called 'jellyfish blooms.'
" 'Usually, screens prevent aquatic life and similar debris from being drawn into the power plants’ cooling system,' the Bulletin of the Atomic Scientists wrote in a 2015 blog post. 'But when sufficiently large volumes of jellyfish or other aquatic life are pulled in, they block the screens, reducing the volume of water coming in and forcing the reactor to shut down.'
"While the case in Scotland has once again spotlighted concerns regarding the jellyfish and potential power plant shutdowns, these concerns are far from new. In 2008, a swarm of jellyfish shut down a nuclear power plant [#DiabloCanyon -- which had another incident in 2024] in #California, and three years later the same occurred at a plant in Japan [#Shimane]. In 2017, jellyfish clogged a power plant in Israel [#Hadera]."

#Jellyfish are taking over the world – and #ClimateChange could be to blame
Jan 8, 2019
by Sean Fleming
Senior Writer, Forum Stories"For 500 million years, jellyfish have been part of the maritime #ecosystem, but now they’re poised to take over the earth.
"They have no brain, no eyes, no spine, not even blood, but they have a remarkable capacity to reproduce and can pack an impressive sting, both literally and figuratively.
"Most recently, vast numbers of bluebottle jellyfish were pushed ashore by unusually strong winds and spells of hot weather in #QueenslandAustralia, stinging thousands of people and forcing the closure of popular swimming spots. About 13,000 stings were recorded in the past week.
"In June last year, over the course of just one week, over 1,000 people were stung in Volusia County, #Florida, following a period of exceptionally prolific jellyfish blooms. The explosion in their numbers has been attributed to warming seas and even increased pollution; unlike many other marine creatures, jellyfish can cope with reduced oxygen levels.
Small but deadly – at least some of the time
"Typically, jellyfish range in size from 1cm to 40cm. But they can be significantly larger – the #LionsManeJellyfish, for example, can reach 1.8 metres wide, with tentacles over 15 metres long.
"For the most part, the sting of a jellyfish is more unpleasant than it is harmful. The pain comes from venom delivered via millions of microscopic barbs in the creatures’ tentacles. Most jellyfish stings will only have a localized effect on the victim – redness, swelling, and discomfort where the barbs make contact with the skin.
"Some, however, will prompt a systemic, whole body, reaction. These may take several hours to emerge and can include symptoms such as headaches, nausea and drowsiness.
"In rare cases, the sting can be fatal. This is true of the #BoxJellyfish, which is spreading into waters that had previously been too cool to support it; its venom causes a severe reaction that can cause death within minutes.
A force of destruction
"But these booming jellyfish populations are doing far more harm than ruining people’s trips to the beach. In fact, the scope of their disruption has extended far beyond the water’s edge.
"In 2011, both reactors at the #TornessNuclearPowerPlant in #Scotland were shut down after an invasion of jellyfish started blocking the cooling filters. Two years later, the jellyfish struck again – this time in #Sweden. They forced the closure of the #OskarshamnNuclearPowerPlant, which contains the world’s largest boiling-water reactor.
"The island of Luzon, home of the Phillippines’ capital Manilla, suffered a blackout in 1999 due to jellyfish, and in 2006 the #USSRonaldReagan, a nuclear-powered aircraft carrier, was brought to a standstill by thousands of the little creatures. And while these events may stand out as exceptions, they are increasing in both scale and frequency.
"From sea-bed diamond mining in Namibia to salmon farming in Ireland, even jeopardising the sustainability of beluga caviar farming in the Caspian Sea, jellyfish are as destructive as they are abundant. And that abundance is being caused by a variety of factors, many of which are related to human activity.
Some like it hot
"Over the last hundred or so years, the average surface temperature of the world’s seas has risen by about 0.9°C. As the oceans get warmer, marine animals are able to spread into areas that had historically been too cold. Oxygen levels in the sea have fallen by around 2% over the last 50 years, due to rising temperatures and #pollution [including #NuclearOceanDumping, which reduces oxygen levels]
"Jellyfish can thrive in areas with lower oxygen levels, where other animals suffer. But there are other factors at work, too. Fishing has depleted the global stocks of some of the jellyfish’s natural predators – such as #tuna and #swordfish – and some they compete with for food – such as anchovies. With more food and fewer predators, some jellyfish populations can grow unchecked.
"In the #BlackSea, unchecked population growth is precisely what’s happened. #AnchovyFishing in the region had caused harm to the Black Sea’s ecosystem by the time stowaway jellyfish made the journey there from the eastern seaboard of the USA. Most likely transported in the ballast water of ships that made the crossing, 1982 saw the arrival of the warty comb jelly. By 1990, there were 900 million tons of them in the Black Sea.
"There are believed to be around 200 different species of jellyfish, not all of which can sting, and some are considered edible. This could offer one potential, and creative, approach toward dealing with an over-abundance of jellyfish – co-opting them onto our dinner plates." [That's one way to deal with invasive species -- eat them into extinction!]

Spike in #jellyfish sightings prompts coastal safety warnings across #Maine
#SouthernMaine communities advise beachgoers to stay alert with increased jellyfish sightings.
Published: 3:29 PM EDT June 24, 2025
Updated: 8:49 PM EDT June 24, 2025MAINE, USA — "Coastal communities in southern Maine are warning beachgoers to stay alert after a rise in jellyfish sightings, including the presence of large #LionsManeJellyfish and #MoonJellies along the shoreline.
"Municipal officials and public safety departments have issued safety advisories in recent days for swimmers, families, and pet owners visiting local beaches.
" 'Today, you may notice our lifeguards flying a purple flag alongside the green flag,' the #OgunquitME Fire Department said in a social media post. 'This indicates the presence of marine life hazards—specifically an increase in lion’s mane and moon jellyfish in our local waters, as well as at other beaches along the Maine coast.'
"While most jellyfish encounters are not harmful, officials said there have been 'a few instances of jellyfish stings locally.' Lion’s mane jellyfish, in particular, can deliver painful stings that remain potent even after the jellyfish wash ashore.
"In #EliotME, police issued a warning after recent sightings near Dead Duck at the Eliot Boat Basin. The department urged caution, especially for families with dogs.
" 'Dogs are especially at risk,' the Eliot Police Department said. 'Curious sniffing or contact can lead to serious injury or illness.'
"Officials recommend keeping pets and young children away from the water’s edge if jellyfish are visible. In addition to avoiding contact, beachgoers are encouraged to report sightings to lifeguards.
"At #WillardBeach in #SouthPortlandME, a nearly five-foot-wide lion’s mane jellyfish was spotted over the weekend, according to the city’s parks and recreation department. Lifeguards have been trained to safely remove jellyfish that wash ashore using tools like shovels.
" 'If you see one, don’t touch it,' the city advised in a public post. 'They sting. Observe it—they’re interesting to watch and pretty too.'
"Those interested in helping marine researchers track #JellyfishSightings can report #observations through regional #CitizenScience platforms or agencies like the #GulfOfMaineResearchInstitute or #BigelowLaboratory for Ocean Sciences.
"In the meantime, officials are reminding visitors to enjoy Maine’s beaches safely and stay informed."

Why the #GulfOfMaine Surface Ocean Waters are Warming Faster than Elsewhere
Posted on July 23, 2024Written by Rob Moir, Ph.D. No Comments
"None of us are strangers to the reports of the Gulf of Maine heating 97% faster than the world’s oceans. However, the actual reasons for this can be lost in the constant headlines about global warming and rising greenhouse gases. To explain this extraordinary phenomenon, let’s look closely at four factors: surface seawater temperatures, heat severity, air temperature, and rainfall, monthly for five years."

So, remember a couple of weeks ago when I posted about visiting the #AtlanticOcean in #Maine, and the water was very warm? I was *not* imagining it!
#Atlantic #HurricaneSeason is almost here, and conditions are primed for 'rapid intensification'
How many hurricanes will there be this year? Will this season be worse than 2024? AccuWeather meteorologists have the answers to these questions and more ahead of the official start of the Atlantic hurricane season on June 1.
By Brian Lada, AccuWeather meteorologist and senior content editor
Published May 21, 2025"One of the biggest factors for tropical development in 2025 is the abundance of warm water available to fuel storms. 'The water temperatures across most of the Atlantic are above average for this time of the year,' AccuWeather Lead Hurricane Expert Alex DaSilva said. 'They're not quite as warm as what we saw last year and in 2023, but they're still well, well above average.'
"Waters are expected to stay warm throughout most of the hurricane season, which will prime storms for explosive development. "

So, since I didn't make it to the beach on Sunday, I decided to visit the beach this afternoon. It was lovely... Hardly anyone there. Not too warm outside (68 F). I dipped my toes in the ocean. The water was warm. The Atlantic Ocean... in Maine! That's not right!

Half of all #eelgrass in #CascoBay has died within last four years, experts say
Eelgrass, according to Friends of Casco Bay, is home to juvenile lobster and fish. Without eelgrass, much of Maine's seafood economy loses its base, they said.

March 29, 2023SOUTH PORTLAND, #Maine — According to a report from Friends of Casco Bay, 54 percent of all eelgrass meadows in Casco Bay have died off since 2018.
"This comes as the 2022 to 2023 winter saw water temps reach four degrees above average.
"'My first response was it's heartbreaking,' Will Everitt, the executive director of Friends of Casco Bay said. 'My second response was now is the time we have to do more than ever to protect the bay.'
"Everitt said eelgrass is dying due to a combination of consequences from the warm water.
"Warm water attracts more invasive #GreenCrabs, which cut the eelgrass and eat softshell crabs, he said. This disturbs the naturally-occurring species, he said.
"'When we have a really cold winter it can kill back the green crabs,' Everitt said.
"He added a warm winter won't kill as many green crabs, allowing them to reproduce and spawn more green crabs for summer and fall.
"'The loss of this is tragic and could have a huge impact on our coastal waters,' Everitt said.
"Everitt added the #WarmingOceans in Maine also result in more frequent #AlgaeBlooms, which prevent the eelgrass from accessing proper sunlight to grow.
"Fewer eelgrass meadows mean fewer lobsters in inshore waters, he added.
"'A number of critters in the bay depend on this... the warming waters are going to do a number on this if it continues,' Everitt said.
"If the situation continues to worsen, Everitt suggested experts would recommend planting eelgrass from more southern states so that subspecies can handle the warmer temperatures Maine is set to experience."

Six rare #sawfish deaths in 7 days have scientists baffled amid bizarre #Florida fish behavior
“There is no concrete, conclusive proof of what is happening yet and that is still to be determined, which is quite terrifying.” said Gregg Furstenwerth, a lifelong diver in the Florida Keys. “If it continues, it is going to be the end of this #ecosystem as we know it.”

"Most tests for toxins have been negative, but scientists have seen an unusually high number of #algae called gambierdiscus that can produce a wide variety of #neurotoxins that can be harmful to fish and dangerous to humans.
#Gambierdiscus is normally found in tropical and subtropical waters all around the world, but the algae can grow quickly when waters are warmer than usual. The climate crisis has brought record hot temperatures to the waters around southern Florida."

Thousands of #eels die mysteriously in #NewZealand
Story by Vishwam Sankaran
April 1, 2024"'We noticed some #algae build-up, which generally is due to the stream water warming up,' said Hona Edwards, a member of a local guardian group that monitors the stream.
"'Then the biggest percentage of the stream was observed to range from very limited to no water flow. When there’s no flow, the dissolved oxygen reduces, and the toxins build up in the waterway,' he said.
"Such algal blooms occur when conditions such as warm water temperatures and low water volumes are coupled with nutrient flows from agricultural use and toxic #pollutants from human activities.
"While mass deaths of freshwater fish are known to occasionally take place across the world, a study of lakes in #Minnesota and #Wisconsin in the United States found that such incidents have increased globally in the past decade."

#Gambierdiscus and Its Associated Toxins: A Minireview
The global spread of #CFP has led to Gambierdiscus and its toxins being considered an environmental and human health concern worldwide.
Da-Zhi Wang, et al.
July, 2022"Gambierdiscus is a dinoflagellate genus widely distributed throughout tropical and subtropical regions. Some members of this genus can produce a group of potent polycyclic polyether #neurotoxins responsible for #ciguatera fish poisoning (CFP), one of the most significant food-borne illnesses associated with fish consumption. Ciguatoxins and #maitotoxins, the two major toxins produced by Gambierdiscus, act on voltage-gated channels and TRPA1 receptors, consequently leading to poisoning and even death in both humans and animals. Over the past few decades, the occurrence and geographic distribution of CFP have undergone a significant expansion due to intensive #anthropogenic activities and global #ClimateChange, which results in more human illness, a greater public health impact, and larger economic losses. The global spread of CFP has led to Gambierdiscus and its toxins being considered an environmental and human health concern worldwide."

WHOI: Harmful Algae: #Gambierdiscus
- Benthic dinoflagellate genus
- Over 18 defined species and several ribotypes identified
- Found globally in tropical and subtropical regions
- Produce #ciguatoxins, which may lead to:
• Human illness (Ciguatera Poisoning)
• Significant public health impacts
• Economic losses associated with health-related costs and lost productivity"Taxonomic studies have identified at least 18 species within the Gambierdiscus genus, many of which co-occur and differ significantly in toxicity. At least ten of these species have been found in tropical and subtropical regions of the U.S., including #Hawaii, the #GulfOfMexico, the #FloridaKeys, #PuertoRico, and the #USVirginIslands.
"Temperature is a key factor controlling CTX occurrence, and laboratory experiments investigating the influence of temperature on growth of various Gambierdiscus species have shown that most species exhibit maximum growth rates between 24–30°C, but that growth responses varied by species. For example, temperature tolerances vary among species, although all are sensitive to higher temperatures, with steep declines in growth as temperatures exceed ~31°C.
"Thus higher temperatures may favor growth of more thermally tolerant species in ciguatera endemic regions, and promote establishment of species shown to be less tolerant in subtropical and temperate regions. Warm surface temperatures may also favor increased abundance of Gambierdiscus populations in deeper waters.
"There is recent evidence of geographic range expansion of #Gambierdiscus and CP into higher latitudes in U.S. waters, associated with climate-driven warming. Over the past two decades CP and CTXs were reported for the first time in the northern Gulf of Mexico, and ephemeral populations of Gambierdiscus have also been documented in #NorthCarolina. Prolonged periods of elevated water temperatures at these locations and in northern Florida are hypothesized to result in increased Gambierdiscus and Fukuyoa cell densities."

Don't count on #nuclear plants to solve #ClimateChange. Hot water discharged from #NuclearPlants cause harmless algae to turn into #ToxicAlgae as well as increase their numbers: "Corals are particularly affected as they can shift the dominance of their symbiotic #algae to more stress-resistant types in [nuclear plant] discharge areas"
Meta-analysis of the thermal pollution caused by coastal nuclear power plants and its effects on marine #biodiversity
Louiza Soares Ferreira Guimaraes, et al.
October, 2023
Abstract:
"The rise in seawater temperature due to industrial activities is one of the main threats to marine biodiversity. In nuclear power plants, large volumes of water are used for their operation, returning to the #ecosystem at higher temperatures. A global meta-analysis was performed to evaluate the thermal effects caused by coastal #NuclearPowerPlants on marine organisms. We found 853 articles of which, 99 were included in the qualitative analysis and 75 in the meta-analysis. The meta-analysis showed an increase of 4.38 °C in water temperature near the outfall, and the temperature variation of each study was found to be associated with the power plant latitudes. The main effects on organisms were related to changes in the structure and composition of aquatic communities, with species abundance, distribution, dominance, and density being the most cited ones. Among the affected groups, photosynthesizing microorganisms were the most cited, potentially contributing to shifts in ecosystem dynamics."
Highlights
• Thermal discharges of nuclear plants caused an increase of 4.38 °C in nearby seawater.
• The temperature difference between sites was correlated with power plant latitudes.
• 38 studies linked temperature as the main factor affecting marine organisms.
• Shifts were noted especially in species abundance (14.65 %) and distribution (13.79 %).
• Among the affected organisms, photosynthesizing microorganisms were the most cited.https://www.sciencedirect.com/science/article/abs/pii/S0025326X2300886X
