							<![CDATA[Namibia has granted an environmental clearance to a controversial marine phosphate extraction project. The clearance allows the Sandpiper Project, operated by Namibian Marine Phosphate (NMP), to dredge the seabed off the coast of Walvis Bay for phosphate. Environmentalists are concerned about the impact on the country’s fisheries sector and the potential health impacts from consuming fish that breed in the areas earmarked for dredging. The Environmental Clearance Certificate (ECC) granted to NMP by the Ministry of Environment, Forestry and Tourism (MEFT) on Aug. 5 allows industrial mining within concession 170 (ML 170) off the west coast of Namibia in country’s Exclusive Economic Zone (EEZ). The concession area covers roughly 2,234 square kilometers (863 square miles) of the Atlantic seabed, according to the company’s website. NMP plans to dredge phosphate-rich sediments present in the seafloor at depths of 180-250 meters. Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors and other water bodies. Nonprofit Ocean Conservation Namibia (OCN) has strongly criticized the decision to issue the ECC, saying “that the large-scale development could have significant impacts on the Benguela marine ecosystem, Namibia’s fishing industry, and marine conservation.” Saltpans in Walvis Bay, Namibia.

							<![CDATA[In 1888, researchers aboard the R/V Albatross began the world&#8217;s first concentrated marine research expeditions off California&#8217;s Pacific coast. The team collected untold plant and animal specimens, including orange cup corals from the Salish Sea, which they carefully preserved and stored in collections at the Smithsonian Institution. These specimens have now become rare physical evidence of ongoing changes in the chemistry of the Pacific Ocean as seawater absorbs the carbon dioxide released into the atmosphere by burning fossil fuels. Researchers recently analyzed these 130-year-old samples, which come from a time before the Industrial Revolution&#8217;s greenhouse gas impacts had really kicked in. Then they compared them with new specimens collected in the same locations by a team aboard another research vessel, the R/V Rachel Carson, in 2020. They discovered that this region is acidifying, far faster than models have predicted, findings they recently published in the journal Nature Communications. “Ocean acidification is not a distant or abstract phenomenon. It is already underway, it is amplified in some regions, and it has real consequences for ecosystems and coastal economies today,” study lead author Mary Margaret Stoll, from the University of Washington, told Mongabay. This research focused on the Salish Sea and the cold California Current System, an interweave of four currents predominantly flowing south from the Canadian province of British Columbia to the Mexican state of Baja California. Prevailing winds push water away from the coast along these currents, drawing water up from the deep, bringing nutrient-rich sediments along with it.

							<![CDATA[Ocean health is moving into a danger zone, with rampant human-caused carbon dioxide emissions having already pushed ocean acidification levels beyond safe limits in large swaths of the marine environment, according to a recent study. The new findings underline the urgent need to ramp up protection of the world’s oceans, while simultaneously slashing CO2 emissions, say experts. But from a scientific perspective, worsening ocean acidification is not an overly surprising finding, considering that carbon dioxide emissions remain high, says lead author Helen Findlay, a biological oceanographer at the Plymouth Marine Laboratory in the U.K. Researchers have known for decades that humanity’s CO2 emissions are being absorbed by seawater, triggering chemical reactions that release hydrogen ions, in turn reducing the abundance of carbonate ions. This ocean acidification process — which has escalated in tandem with atmospheric emissions — has implications for a large number of ocean-dwelling calcifying species that rely on calcium carbonate for their shells, with harm to those species potentially reverberating throughout marine ecosystems. “We have really good data sets, and the data sets and this paper really just emphasize that we&#8217;re just watching the system crash.… [W]e need to be making real change now so that we don&#8217;t make things worse,” Findlay says. “In my assessment, [this new paper] confirms what we&#8217;ve been expecting,” agrees Johan Rockström, director of the Potsdam Institute for Climate Impact Research in Germany, who was not involved in the current study. “[W]e are unfortunately moving beyond the safe boundary on ocean acidification.” Researchers&hellip;This article was originally published on <a href="https://news.mongabay.com/2025/06/as-ocean-acidification-ramps-up-experts-call-for-speedy-ocean-protection/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Ocean-based carbon dioxide removal technology is ramping up, with startups and existing companies racing to develop electrochemical techniques that either remove carbon from seawater or prompt oceans to suck up more. Electrochemical marine carbon dioxide removal (mCDR) aims to store carbon in the ocean or strip it from seawater using electricity. Broadly speaking, mCDR is divided into two methods with some overlap: ocean alkalinity enhancement (OAE) and direct ocean capture (DOC), also known as direct ocean removal. OAE electrochemically splits seawater into a base and acid stream. The base stream is added back to the ocean, notching up pH to make the ocean’s surface more alkaline, prompting more CO2 to be absorbed from the atmosphere over time in the form of bicarbonate. The acidic stream can be used by industry or sequestered in the deep sea. “If you think of the ocean like a sponge, adding alkalinity makes that sponge bigger, so it&#8217;s able to take up more carbon dioxide,” says Helen Findlay at the Plymouth Marine Laboratory. DOC also uses electrochemical processes to strip carbon dioxide from seawater. One method converts dissolved inorganic carbon within seawater into a gas that is then captured. Low CO2 water is returned to the ocean, where it naturally rebalances as carbon dioxide is drawn down from the atmosphere. The captured carbon can be stored geologically or used in industrial processes, much like direct air capture on land. “Back to the sponge analogy, direct ocean capture is like squeezing the sponge and then allowing&hellip;This article was originally published on <a href="https://news.mongabay.com/2024/12/electrochemical-removal-of-ocean-co2-offers-potential-and-concerns/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Coral reefs support fisheries, protect coastal communities, and sustain tourism worldwide. However, rising ocean temperatures and acidification from the climate crisis threaten these ecosystems. Scientists warn that even if the Paris climate agreement targets on reducing emissions are met, massive coral reef loss is inevitable and reefs could collapse within decades, impacting a billion people who depend on them globally. Yet the situation may not be quite so grim, according to a recently published study that challenges the 2023 prediction by the U.N.&#8217;s Intergovernmental Panel on Climate Change that coral reefs will decline by more than 99%. It suggests that reefs could instead adapt and avoid collapse, albeit with significant changes. The study authors say the findings nevertheless underscore the need to reduce local stressors and make rapid, deep cuts in carbon emissions to meet the Paris Agreement&#8217;s warming limit of 2° Celsius (3.6° Fahrenheit) above pre-industrial temperatures. “Coral reefs are not inevitably doomed,” lead author Christopher Jury, a post-doctoral researcher at the University of Hawaiʻi at Mānoa’s Hawaiʻi Institute of Marine Biology, told Mongabay by email. A research diver encounters Porites evermanni coral in Hawai’i. Image courtesy of Keoki Stender. The new paper acknowledges that even if the world agrees to reduce carbon emissions, temperatures will keep rising, “such that reaching or even exceeding [Paris Agreement] targets now seems inevitable.” “If we limit climate change to Paris Climate Agreement targets, or at least get relatively close, and also manage local stressors such as destructive fishing practices and coastal pollution,&hellip;This article was originally published on <a href="https://news.mongabay.com/2024/12/coral-reefs-could-survive-climate-change-but-in-altered-state-study-says/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[The first ever pulse check of the planet’s health shows that the Earth is far beyond it’s safe operating space for humanity. Six of nine key planetary boundaries are already transgressed, and continue moving deeper into risk zones that could threaten our planet’s habitability. A seventh boundary, ocean acidification, is on the verge of transgression and may exceed safe limits in a matter of years. That’s according to the first-ever Planetary Health Check, a nearly 100 page report produced by the new Planetary Boundaries Science (PBScience) initiative led by Earth System scientist Johan Rockström and the Potsdam Institute for Climate Impact Research (PIK), and supported by the Planetary Guardians and other partners. Boundaries for climate change, biosphere integrity, land system change, freshwater change, biogeochemical flows, and the introduction of novel entities (such as synthetic chemical pollutants) are all surpassed, as a study published last year found. Worryingly, in this latest report, all those already transgressed are moving deeper into the red zone, says Levke Caesar, a report author and co-leader on planetary boundaries at the Potsdam Institute for Climate Impact. “Our updated diagnosis shows that vital organs of the Earth system are weakening, leading to a loss of resilience, and rising risks of crossing [irreversible] tipping points. “We see it&#8217;s not changing [for the better]. It is actually getting worse,” she says. The breach of planetary boundaries heightens the risk of permanently damaging Earth’s life support functions, with the report warning that the world is entering a “dangerous new era.”&hellip;This article was originally published on <a href="https://news.mongabay.com/2024/09/inaugural-planetary-health-check-finds-ocean-acidification-on-the-brink/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[The Earth is in crisis — a reality made increasingly clear by intensifying heat, drought and storms, worsening pollution, land stripped of forests, and the ramping up of the sixth great extinction. But some scientists say we’re failing to prioritize a critical Earth change that is accelerating in the modern world and that helped drive past global extinction events: aquatic deoxygenation. In 2023, scientists suggested that anoxia, the lack of dissolved oxygen in a water body, played an important role in ocean ecosystem disruption and extinctions during the Triassic-Jurassic mass extinction around 200 million years ago, while others say it contributed to the “great dying” of the Permian extinction 50 million years earlier, which wiped out 90% of all marine species. Today, human-caused hypoxia (reduced oxygen levels), due increasingly to synthetic agricultural fertilizer pollution and climate change, annually helps create vast dead zones in the Gulf of Mexico, Baltic Sea, East China Sea, and estuaries, lakes and streams around the globe. Now, a new perspective piece in Nature Ecology &amp; Evolution seeks to add aquatic deoxygenation of both fresh- and saltwater ecosystems to the planetary boundary framework, a theory currently used to define the safe operating limits for Earth’s natural systems. Red tide under the Astoria Bridge, Oregon, U.S. Image by Alex Derr via Flickr (CC BY-NC-SA 2.0).

							<![CDATA[ATHENS — At 88, Sylvia Earle is at an age when most people would be slowing down. But retirement doesn’t appear to be on the radar of the famous oceanographer and marine biologist, known by many as “Her Deepness” due to the more than 7,500 hours she’s spent underwater. When Earle’s not diving in the ocean, she’s speaking at events or campaigning for her nonprofit organization, Mission Blue, with boundless energy to inspire global action to protect the ocean. As she told Mongabay, “When you&#8217;ve seen what I&#8217;ve had the privilege of seeing, I&#8217;m just driven to try to share the view.” For some, Earle needs no further introduction. But for those unfamiliar with her, it’s worth knowing a little about her life and work. Earle studied biology and oceanography before earning a Ph.D. in phycology, the study of algae. Early in her career, before her doctoral studies were complete, Earle joined several research expeditions, including ones that voyaged into the Indian Ocean, the Galápagos Islands, the Chilean coast, and the Panama Canal Zone between 1964 and 1966. She was one of the only women on board for many of these expeditions. In 1968, Earle became the first woman scientist to descend into the ocean in a submersible vehicle, which she did as part of the Smithsonian Institution’s Man-in-Sea project. The following year, Earle led an all-female team to participate in the Tektite II Project, which required the team to live 50 feet (15 meters) underwater for two weeks to&hellip;This article was originally published on <a href="https://news.mongabay.com/2024/05/our-life-support-system-is-at-risk-interview-with-her-deepness-sylvia-earle/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[In 2009, a controversial scientific experiment dumped 6 metric tons of dissolved iron into the Southern Ocean to see if it would trigger a massive bloom of phytoplankton in iron-deficient waters. In one way, the experiment succeeded: The scientists produced a phytoplankton bloom. However, they didn’t get what they were really after: Proof that such a scheme could lead to large-scale carbon dioxide sequestration. You see, when phytoplankton die, they sometimes sink to the bottom of the sea — a phenomenon known as marine snow — carrying the carbon dioxide they absorbed during photosynthesis with them to be sequestered in the seabed for decades to millennia. In 2009, the vast majority of the experimental bloom was consumed by zooplankton near the surface and failed to reach the ocean floor. Since then, except for an even more controversial attempt by a for-profit company in 2012 in Canadian waters, there have been no large-scale experiments of ocean iron fertilization as a potential tool to counteract climate change. Now, researchers hope to change that. Dennis McGillicuddy and Ken Buesseler, both with the Woods Hole Oceanographic Institution in Massachusetts, U.S., have a multistage project in mind that Buesseler says would be about “10 times longer [and] 10 times bigger” than any past experiment. They say they hope such a scaled-up experiment will answer many of the questions that still remain about the efficacy of ocean iron fertilization. McGillicuddy says iron fertilization remains intriguing because it has the potential to store “gigatons per year” of&hellip;This article was originally published on <a href="https://news.mongabay.com/2023/11/is-ocean-iron-fertilization-back-from-the-dead-as-a-co%e2%82%82-removal-tool/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[At eight in the morning, the sun is already scorching the avenues and shopping malls of Barra da Tijuca, an upper-middle-class neighborhood on the west side of Rio de Janeiro. From the scalding runway of a busy private airport, helicopters transport tourists and executives along one of the most beautiful and renowned coastlines in the world. One of these helicopters is preparing to take off as Mario Moscatelli settles into the passenger seat and checks his camera. There will be no images of Christ the Redeemer; the biologist&#8217;s eyes are trained to see things most tourists prefer to ignore. Behind the buildings, a wide coastal plain is revealed, embraced on three sides by mountains with a dramatic profile. Between the white rows of luxury condo towers and car-lined avenues stretch long lagoons, each surrounded by a thin border of mangrove swamp. The Lagoon Complex of Jacarepaguá is what remains of a once-untouched tropical ecosystem that connected the surrounding Atlantic Forest with the ocean. Instinctively, the biologist points his telephoto lens downward, snapping pictures of the lagoons at a point where deep blue water mixes with a brilliant green. The odd color is evidence of high levels of cyanobacteria that thrive in organic material — in this case, thousands of liters of raw sewage. Seemingly unconcerned, jet skis cross the toxic mix in front of Iberian-style mansions with tennis courts and swimming pools. Degraded over decades of feverish urban expansion, the so-called Veneza Carioca, in its current state, is just the&hellip;This article was originally published on <a href="https://news.mongabay.com/2023/08/the-endless-struggle-to-clean-up-rio-de-janeiros-highly-polluted-guanabara-bay/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[The marine biodiversity hotspot known as the Coral Triangle is home to more than 76% of the world&#8217;s known coral species and more than 3,000 species of fish. It sustains the livelihoods of more than 100 million people living along the coasts of Indonesia, Malaysia, Papua New Guinea, the Philippines, the Solomon Islands and Timor-Leste. It&#8217;s also home to a lot of plastic. Much of the waste clogging the waters of Coral Triangle countries is the result of poor waste management at the local and national levels. But a recent study published in the Journal of Marine Science and Engineering shows that plastic also comes from much farther afield. It found that microplastics in the Mekong River in mainland Southeast Asia are spreading to the densely populated coasts of the archipelagic countries of the Philippines and Indonesia. As the region hosts some of the richest fauna and flora on the planet, experts say these findings show that cooperation between Southeast Asian nations is crucial to reduce the harm done to marine life and the communities that depend on aquatic resources.

							<![CDATA[Imagine showers of little green sand grains drifting through the ocean: collecting on coral reefs, rolling off the backs of whales, sprinkling schools of tuna — and helping to save all those creatures, and humanity, too. At least that’s the idea. These green showers are crushed olivine, an abundant volcanic mineral, delivered by a fleet of ships. And it is climate change that launched these thousand ships, crisscrossing the ocean in a surreal bid to undo the damage we’ve done. You see, as the olivine settles on the ocean floor it disintegrates and chemically transforms, making that part of the ocean a little more alkaline and converting dissolved CO2 into carbonate and bicarbonate molecules, a process that stores the carbon for hundreds of thousands of years. The seawater can then trap more CO2 from the air to replace the stored carbon. Scientists call this ocean alkalinity enhancement, or OAE, and some believe it could be a vital tool for drawing down and securely storing a portion of the 1.5 trillion tons of CO2 that we’ve added to the atmosphere since the industrial revolution, not to mention the billions more we’ll add before we hit net zero. Olivine is a volcanic mineral which, when introduced to the ocean, disintegrates and chemically transforms, making that part of the ocean a little more alkaline and securely storing dissolved CO2 as carbonate and bicarbonate molecules.

							<![CDATA[A stone causeway connects an islet, the famed Aragonese Castle perched atop it, to the island of Ischia off the coast of Naples in southern Italy. Below water, along the islet’s northern and southern contours, CO2 bubbles from volcanic rocks. Across these effervescent strips of seabed, pH ranges from an extreme low of 6.6 to a normal 8.1. Between 7.8 and 7.7, values that according to worst-case climate projections will be common in ocean waters globally by the end of the century, seagrass and macroalgae, or seaweed, dominate the seascape. Since 2008, scientists from all over the world have been using this area as a natural biogeochemistry lab and a window on the future. Researchers working in these waters, naturally acidified due to the presence of underwater volcanoes, are studying animal and seagrass populations that have inhabited these rocks for generations, among other aspects of local ecology. “We have photosynthetic organisms like [the seagrass] Posidonia and other types of macroalgae, which are already somehow adapted to marine acidification,&#8221; Marco Munari, a marine ecologist and ecotoxicologist at Zoological Station Anton Dohrn (SZN) in Naples told Mongabay in an interview. Until earlier this year, Munari was coordinator of SZN’s Ischia Marine Centre; he has since moved to a different SZN branch in Fano. The local populations of these organisms are already prepared for the stressors that populations in other areas might experience in a not-so-distant future.

							<![CDATA[Melting sea ice may evoke images of polar bears stranded on shrinking floes or dramatically collapsing ice shelves. But according to a study published recently in the journal Science, ice melt is triggering another ecological threat: a drastically acidified Arctic Ocean. This has diminished access to key chemical building blocks for organisms that call the Arctic home, potentially disrupting the entire food web in this region. An international team led by scientists at the University of Delaware found that the Arctic Ocean grew 50% more acidic from 1996 to 2020, changing three times faster than the rest of the ocean. “I thought it would be a little bit higher,” said study co-author Wei-Jun Cai, a marine chemist at the University of Delaware. “But I didn&#8217;t know it would be that high.” Sun illuminates melting ice floes in the western Arctic Ocean. Scientists estimate that Arctic summer ice will disappear completely by 2050. (Courtesy of Zhangxian Ouyang) The Arctic is warming faster than any similar region on Earth, causing sea ice to retreat rapidly. Ocean water trapped under the ice is low in carbon dioxide, which dissolves readily in cold water. But as the icy shield melts, these frigid waters suck up carbon dioxide from the air, forming a carbon-rich layer that sits on top of the ocean. When carbon dioxide dissolves in water, some of it reacts to form acid. So Cai, who first reported this carbon-rich layer 12 years ago, wondered whether these Arctic waters might grow more acidic&hellip;This article was originally published on <a href="https://news.mongabay.com/2022/12/melting-ice-created-the-perfect-storm-for-a-rapidly-acidifying-arctic-ocean/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[The 2015-16 El Niño fueled deadly record cyclones in the South Pacific and Mexico, as well as  severe droughts that resulted in thousands of early deaths from fires and haze in southeast Asia and tens of millions going hungry amid crop failures in southern Africa. Strong El Niños like that one could happen more frequently in the future as Arctic sea ice starts to disappear in the summer, according to a recent study published in Nature Communications. The research is the first to find a direct link between sea ice loss and the occurrence of El Niño, a warming of surface water in the eastern Pacific off of Peru that encourages higher global temperatures and extreme weather around the planet. Research has already indicated that the warming Arctic is affecting weather in the mid-latitudes, such as when polar vortex “stretching” likely contributed to a deadly cold wave in Texas last year. But the new study suggests that changes in the Arctic will also influence the tropics. Arctic pack ice. The Arctic is warming at a rate up to four times faster than the planet as a whole and has lost a third of its sea ice volume in just two decades.

							<![CDATA[The trillions of pieces of plastic currently roving through the global ocean are known to be an assault on life. Turtles get tangled up in discarded plastic fishing nets. Whales open their mouths to eat and unwittingly fill their stomachs with shopping bags. Filter-feeding fish and other organisms gobble up tiny plastic particles, poisoning themselves with the plastic’s toxins and passing that toxicity along to any animal that consumes them. And now, new research suggests that plastic pollution could be harming the ocean in an additional way: by contributing to its acidification. Through a series of laboratory experiments, scientists from the Marine Sciences Institute in Barcelona, known as ICM-CSIC by its Spanish acronym, found that when plastic — especially aged, degraded plastic — interacts with sunlight, it releases a cocktail of chemicals, including organic acids, into the ocean. Organic acids are known to lower the pH of seawater, causing it to become more acidic. In addition, the sun’s degradation of plastic can lead to carbon dioxide (CO2) release, which can cause pH to plummet further. In highly polluted parts of the ocean, such as coastal areas, plastic could contribute to a drop of up to 0.5 pH units, which is “comparable to the pH drop estimated in the worst anthropogenic emissions scenarios for the end of the 21st century,&#8221; says Cristina Romera-Castillo, a postdoctoral researcher at ICM-CSIC and lead author of the study documenting the findings. Lead author of the study Cristina Romera-Castillo examines a sample of polluted ocean water.&hellip;This article was originally published on <a href="https://news.mongabay.com/2022/10/one-more-thing-about-plastics-they-could-be-acidifying-the-ocean-study-says/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Hours after being born, oysters are already working to form their protective, chalk-layered shells. Drawing calcium and carbonate from seawater, they combine the two to form hardened shells. But as humans have pumped voluminous sums of carbon dioxide into the atmosphere, this ancient process has come under threat. It’s estimated that the global ocean absorbs around 30% of human carbon emissions. While this carbon sequestration creates a powerful buffer against climate change by reducing the amount of CO2 flowing into the atmosphere, it changes the chemistry of seawater, decreasing the pH and causing seawater to become more acidic. Besides affecting oysters, ocean acidification can dissolve the aragonite (a form of calcium carbonate) shells of pteropods, tiny marine snails that swim through the water column, and which whales, seabirds and fish rely on as a food source. Acidification slows corals’ ability to grow their skeletons. Marine animals like sea urchins find it more difficult to reproduce. New research has also shown that ocean acidification can exacerbate other issues, including the impacts of marine heat waves, compounding stress on an already stressed-out ocean. Ocean acidification is considered to have such wide-ranging global impacts that scientists have designated it as one of nine planetary boundaries responsible for regulating and maintaining Earth’s functionality. Each of these nine boundaries refers to a biophysical subsystem or process that has a clear limit to which it can withstand anthropogenic changes. The theory, which was first introduced in a 2009 paper and updated in a 2015 paper, suggests&hellip;This article was originally published on <a href="https://news.mongabay.com/2022/09/acid-test-are-the-worlds-oceans-becoming-too-acidic-to-support-life/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[In deep waters off the coast of Japan, a hermit crab is wearing haute couture. On its shell is the new-to-science anemone species Stylobates calcifer, named after the fire demon Calcifer from the novel and Studio Ghibli film Howl&#8217;s Moving Castle. A research team led by Akihiro Yoshikawa, a professor from the University of Tokyo, collected the anemone-hermit crab duo from the sea floor at a depth of 100 to 400 meters (330 to1,300 feet) in the sea of Kumano and Suruga Bay on the Pacific side of Japan. Researchers have published descriptions of the new anemone species in The Biological Bulletin. The newly described anemone species appears to live exclusively on the shells of the hermit crab species Pagurodofleinia doederleini, a hint that these two species are in an obligate symbiotic relationship, or that they need each other to survive. The new-to-science anemone species Stylobates calcifer on the back of its hermit crab host. Photos by Akihiro Yoshikawa from Yoshikawa et al 2022. Much like a conch shell, anemones use their own secretions to form their shell-like attachments (in this case, to their hermit crab host). “The shell-making ability of the new species in the species-specific relationship appears as if Calcifer was in a magical contract with the Wizard Howl, constructing his Moving Castle,” Yoshikawa told Mongabay in an email. In a series of first-ever video recordings of the hermit crab and anemone duo, the crab is seen moving into a larger shell.

							<![CDATA[When is seaweed much more than seaweed? In the United States, seaweed farms are sprouting up all over the country, but on the east end of Long Island, New York, a new project cultivating kelp in the waters of Shinnecock Bay is more than a follower of a new trend. The Shinnecock Kelp Farm is the first Indigenous-owned seaweed farm on the East Coast. Its founders hope that it may alter the course of a bay devastated by pollution — and, perhaps, restore the sovereignty of the tribe that cultivated these waters for millennia. “It really goes back to this concept of reciprocity; Indigenous people know that if we take care of Mother Earth, that Mother Earth will then take care of us,” says Tela Troge, one of the six women running the farm. Troge is also a member of the Shinnecock Nation, the tribe that lived on the bay since the end of the last Ice Age. Tela Troge heads back into shore from the kelp lines. Behind her and to the right you can see Shinnecock Nation territory.

																					<content:encoded>
							<![CDATA[Blocking the sun’s rays with an artificial particle shield launched high into Earth’s atmosphere to curb global temperatures is a technological fix gaining traction as a last resort for containing the climate crisis — but it needs to be stopped, wrote a coalition of over 60 academics in an open letter and article released in the WIREs (Wiley Interdisciplinary Reviews) Climate Change online publication on January 17. “Some things we should just restrict at the outset,” said one of the open letter&#8217;s lead authors, Aarti Gupta, a professor of Global Environmental Governance at Wageningen University. Gupta placed solar geoengineering in the category of high-risk technologies, like human cloning and chemical weapons, that need to be off-limits. “It might be possible to do, but it’s too risky,” she told Mongabay in an interview. The color of the sky could change. The chemical composition of the ozone layer and oceans may be permanently altered. Photosynthesis, which depends on sunlight, may slow down, possibly harming biodiversity and agriculture. And global weather patterns could change unpredictably. Despite the potential dangers, no mechanism exists today to stop an individual, company or country from launching a solo mission, said Gupta. To prevent this, the open letter suggests five urgent protective measures: no outdoor experiments, no implementation, no patents, no public funding, and no support from international institutions such as the United Nations. The 1991 Mount Pinatubo volcanic eruption in the Philippines threw enough sulfate and other aerosol particles into the stratosphere to cool the Earth.

							<![CDATA[The ocean is now warmer than it’s ever been in recent history, according to a new study. And this isn’t the first time such a record has been set. For the past six years, ocean temperatures have exceeded each previous year in a trend one scientist calls “inexorable.” Human-induced climate change is to blame, says John Abraham, co-author of the new study published Jan. 11 in Advances in Atmospheric Sciences.  “We should be very concerned,” Abraham, a professor of thermal sciences at the University of St. Thomas in Minnesota, U.S, told Mongabay in a video interview. “But frankly, we should have been concerned years ago.” The research team used a network of high-tech autonomous ocean buoys to measure global ocean temperatures, which they compared to data from the 1950s. They found that in 2021, the upper 2,000 meters (6,600 feet) in all of the oceans absorbed 14 zettajoules more of human-made energy than the previous year, equal to about 145 times the world’s electricity generation in 2020. Abraham puts it another way: “It&#8217;s the equivalent of seven Hiroshima atomic bombs detonated every second of every day of every week of every month. “The story we&#8217;ve been telling since 2018 is that every year it&#8217;s getting hotter and hotter,” he added. “And records are being broken as this inexorable, unrelenting rise of ocean temperatures occurs.” The global upper 2000 meters of ocean heat content from 1958 through 2021.

							<![CDATA[Environmental causes have traditionally attracted only a small share of philanthropic support in the United States: Between 1-3% of annual giving, depending on how the issue area is defined. But that may be changing as the impacts of climate change worsen and awareness of the links between a healthy planet and healthy society rises. Sonali Patel, a partner with The Bridgespan Group, which advises nonprofits and philanthropists on strategy, told Mongabay that she’s seeing more interest among donors in climate issues. She said that philanthropy can be particularly impactful in the climate space by supporting innovative ideas that may be too risky for investors or governments and putting resources into areas that may not otherwise attract attention. “Currently only 1% of spend on climate change comes from philanthropy,” she told Mongabay during a recent interview. “Philanthropy can play a unique role in funding where either the risk is too great or there is a whitespace.” Of those gaps, Patel cited ocean acidification and climate equity as examples. “The entire [ocean alkalinity/ acidification] field has about $5M of investment but the potential in the field is large,” she said. On climate equity, she pointed to the gains that could be realized by strengthening Indigenous peoples’ rights. “Indigenous peoples are the best stewards of current sinks and have few legal rights to their land. Protecting their rights and livelihoods can have significant impact on preserving our natural sinks and increase the economic productivity and support the communities who will be most impacted&hellip;This article was originally published on <a href="https://news.mongabay.com/2021/09/climate-philanthropys-opportunity-for-impact-qa-with-bridgespans-sonali-patel/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Advanced human societies emerged during an unprecedented period of stability on Earth. During the 12,000 years prior to the Industrial Revolution, our planet’s surface temperature varied by less than 1° Celsius (1.8° Fahrenheit) above or below the average for that entire period. As a result, life — both human and wild — thrived. But over the past two centuries, humanity has dramatically increased greenhouse gas concentrations in the atmosphere, pushing us outside this “safe” climate zone; outside the conditions for which civilization has been designed. Unfortunately for us, climate change represents just one of nine critical planetary boundaries, which the imprudent actions of our species risk dangerously destabilizing and overshooting. The nine planetary boundaries, counterclockwise from top: climate change, biosphere integrity (functional and genetic), land-system change, freshwater use, biogeochemical flows (nitrogen and phosphorus), ocean acidification, atmospheric aerosol pollution, stratospheric ozone depletion, and release of novel chemicals (including heavy metals, radioactive materials, plastics, and more). Image courtesy of J. Lokrantz/Azote based on Steffen et al. 2015 (via Stockholm Resilience Centre). A safe operating space for humanity In the mid-2000s, Johan Rockström, founding director of Sweden’s Stockholm Resilience Centre, gathered an international, interdisciplinary team of scientists to unite behind a single goal: define the boundaries for a “safe operating space for humanity” on Earth. They asked themselves: what are the safe operating limits of our planet, and what changes can we force on it before we trigger rapid, catastrophic environmental harm? In 2009, the center published the Planetary Boundaries Framework, which outlined&hellip;This article was originally published on <a href="https://news.mongabay.com/2021/03/the-nine-boundaries-humanity-must-respect-to-keep-the-planet-habitable/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[1. The ocean in a worldwide pandemic As the year that challenged the world with a widespread pandemic draws to a close, COVID-19 has affected almost every aspect of life as we knew it. Even the ocean, the most powerful force in the world, is not immune to its effects. The amount of marine plastic pollution, 13 million tons of which was already entering the ocean each year, has certainly grown with the addition of improperly disposed personal protective equipment, such as single-use masks and gloves. People are using an estimated 129 billion face masks and 65 billion gloves every month; one report predicts that 1.56 billion face masks could end up in the ocean this year. State and city rollbacks on bans of plastic items like bags and utensils due to concern over spreading the virus via reusable options could contribute as well. The influx of yet more plastic to the sea not only poses a threat to human health, but also heightens the risk of injury or death to some 600 wildlife species that may consume debris they mistake for food. On a brighter note, the early days of the pandemic provided a rare opportunity to study a quieter underwater habitat resulting from reduced worldwide trade. Researchers examined underwater sound in real-time near the port of Vancouver and found a consistent reduction in low-frequency sound attributed to ship traffic from January to April, when imports and exports dropped 20%.

							<![CDATA[How does a business grow and expand, but function in a way that doesn’t overexploit the Earth? A new enterprise is offering an answer to this question. Last week, the Science Based Target Network (SBTN), an offshoot of a global partnership called the Global Commons Alliance (GCA), launched a program to help companies, consultancies and industry coalitions set environmental targets that would help them operate sustainably. Carbon emissions are often the focus of sustainable business models, but the SBTN aims to broaden this approach by offering guidance on how companies can take action to protect all aspects of the natural world alongside climate. While the SBTN is still in its infancy, the organizers say the project has the potential to draw an array of companies — from small businesses to large, multinational corporations — into a global partnership that can proffer solutions to the world’s sustainability issues. The SBTN’s goal, as set out in its initial guidelines for companies, is to create a “nature-positive world,” in which nature loss is brought to a standstill, enabling the natural world to mount a recovery.

							<![CDATA[When scientists first discovered glass sponge reefs in British Columbia’s waters in the late 1980s, they couldn’t have been more surprised. Prior to this, they believed that glass sponge reefs went extinct 40 million years ago. “If you think of it, it’s like stumbling upon a whole herd of dinosaurs in our backyards,” says Angela Stevenson, a researcher based in British Columbia who studies glass sponges intensively. Glass sponge reefs may have outlived the dinosaurs, but they may not survive much longer. In May, Stevenson and her colleagues published a study in Scientific Reports that warns that the impacts of climate change will likely weaken glass sponges’ skeletal strength and filter-feeding ability. The team from the University of British Columbia (UBC) explored the dual impacts of ocean warming and acidification on one of the only three reef-building glass sponge species in the world, the cloud sponge (Aphrocallistes vastus). Working in a lab, the scientists placed the sponges in conditions mimicking future projected warming and acidification, based on scenarios from the Intergovernmental Panel on Climate Change (IPCC). While individual glass sponges are found worldwide, glass sponge reefs are unique to the Northeast Pacific Ocean. These deep-sea reefs can grow to 19 meters (62 feet) in height, and rise to 22 meters (72 feet) below sea level, allowing for scientists in British Columbia to dive to the ancient reefs and study them closely.

							<![CDATA[In March, Australia’s Great Barrier Reef suffered its most widespread bleaching event to date. Sixty percent of the reef underwent moderate to severe bleaching, and some corals may never recover. The cause of this bleaching event was climate change, which brought unusually warm waters to the Great Barrier Reef in February, and disrupted the delicate, symbiotic relationship between the corals and their life-sustaining algae. In general, when sea temperatures rise, corals become stressed and expel algae from their tissues. Without this algae, the corals turn ghostly white and slowly starve. An Acropora coral reef in Chuuk, Micronesia. Image by David Burdick, NOAA. But there’s another big threat to coral reef systems, one that could be more serious than sea temperature rise and acidification. According to David Hughes, lead author of a new study published in Nature Climate Change, corals and other organisms living on the Great Barrier Reef could also be suffering from deoxygenation, and this could greatly impede the reef’s recovery. “We know that the stresses of warming and the deoxygenation are likely to interact with each other,” Hughes, a research associate at the University of Technology Sydney’s Climate Change Cluster, told Mongabay. He explained that as water warms, corals and other organisms need more oxygen to breathe. But warm water holds less oxygen than cold water. As corals and other organisms struggle to get the oxygen they need, they consume more oxygen in the process.

							<![CDATA[1. Climate change and oceans Climate change impacts on land made almost daily headlines this year: fires, floods, more extreme storms. Equally intense effects are being realized in our seas. This year, more than 100 scientists from 30 countries brought these impacts on the ocean into sharp focus with the Intergovernmental Panel on Climate Change (IPCC) special report on the ocean and cryosphere. The findings were bleak: Sea level rise is accelerating, marine heatwaves are more extensive and intense and coral bleaching events are occurring with increasing frequency. The report’s predictions up the ante on action. Even if we meet the Paris Agreement mandate to keep warming to below a 2-degree Celsius rise over pre-industrial levels, the report suggests that by 2100 sea levels will rise by 0.3 to 0.6 meters (1 to 2 feet), there will be 20 times more marine heatwaves and the ocean will be 40% more acidic. The urgency for ocean/climate action was happily mirrored at the close of this year with an all-time bump in importance for oceans at the recent U.N. climate negotiations (COP 25) in Madrid, with the event even being billed by some as the “Blue COP.” Roads washed away due to sea-level rise and storm surge from Hurricane Sandy at Assateague Island off the coast of Maryland and Virginia in 2012.

							<![CDATA[As humans continue to emit record levels of carbon dioxide, we are putting marine habitats at risk. One consequence of these emissions, ocean acidification, is a serious threat to many undersea environments—especially coral reefs. Now, a multinational study on the Great Barrier Reef in Australia offers a small ray of hope. Reefs with higher numbers of living corals will be more resilient than expected to damage from acidifying seawater, scientists reported recently in Nature Evolution and Ecology. A healthy coral reef community on Heron Island in the Great Barrier Reef. Photo Credit: Ove Hoegh-Guldberg at Oregon State University on Wikimedia Commons. The ocean absorbs much of the carbon dioxide we put into the air, converting it to a molecule called carbonic acid. This acid makes it harder for corals to recruit the building blocks they need to grow their skeletons. Worse, coral skeletons start to dissolve when seawater becomes too acidic. The Intergovernmental Panel on Climate Change predicts in one model that the average pH on reefs could drop 0.25 units by 2100. That sounds like a small change, but it could devastate corals. Researchers have previously simulated ocean acidification in simple aquariums, showing that corals struggle to thrive—much less survive—as the acidity in the tank worsens. But David Kline, a staff scientist at the Smithsonian Tropical Research Institute in Ancon, Panama, and first author of the study, wanted to move beyond the “glass box” and look at ocean acidification in a more realistic setting.

							<![CDATA[PALAWAN, Philippines — Twenty years ago, people in this fishing village in the municipality of Quezon, on the Philippine island of Palawan, would just walk to the shore, throw a net, and haul in an abundant catch of big fish for their own meals and to sell in the local market. But over the next few years, the fishermen suddenly found themselves sailing out farther into rough waters, for 24 hours or more at a time. Small catches they got were just enough to pay for the boat fuel and daily expenses. Budenido Calderos, 46, a fisherman from Barangay Isugod, a ward in Quezon, says it’s the same story in other parts of the fishing community: it’s getting increasingly difficult to find fish. Calderos has trouble pinpointing a single reason; most of the fishermen blame a combination of overfishing, pollution, increasing population in the villages and may be warming seas and changing rainfall patterns that are triggering more cyclones. Fishing has traditionally sustained communities in the archipelagic province of Palawan that borders the marine resource-rich West Philippine Sea, supporting nearly 850,000 people in the province. “I have been fishing for more than 20 years and it is becoming more difficult to catch fish. It is getting harder and harder to find fish nowadays. Between rising costs of living and falling catch, our income were low and erratic,” Calderos says. Like many other fishermen in his village, he’s had to supplement his income with extra work, such as working at a private fishpond in the nearby village,&hellip;This article was originally published on <a href="https://news.mongabay.com/2019/06/small-scale-women-seaweed-farmers-ride-the-rough-tides-of-climate-change/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Research over the past few years has shown that ocean acidification impacts Atlantic cod at the earliest stages of their lives, while they are still eggs and larvae. Scientists hoped that those cod who managed to reach maturity might be helping the species adapt to the conditions brought on by global climate change. But new research appears to have dashed those hopes. Earth’s oceans absorb as much as one-third of the excess carbon dioxide pumped into the atmosphere by human activities. When that CO2 reacts with water, it forms carbonic acid, lowers the pH level of marine waters, and thus makes the oceans more acidic. While marine species can shift their ranges to avoid the warmer water temperatures driven by climate change, there is no way for them to escape ocean acidification. For a 2016 study, Martina Stiasny of the GEOMAR Helmholtz Centre for Ocean Research, a research institute in Kiel, Germany, led a research team that conducted experiments with Atlantic cod (Gadus morhua) caught from two wild populations in the Western Baltic and the Barents Sea. The researchers determined that, at the ocean acidification levels expected by the end of the century if we do nothing to draw down C02 emissions, twice as many cod larvae will die within their first 25 days, causing the number of cod who reach maturity and reproduce to drop by 8 and 24 percent for the Western Baltic and Barents Sea populations, respectively. Stiasny was among the scientists who&#8217;d hoped that those cod&hellip;This article was originally published on <a href="https://news.mongabay.com/2019/03/ocean-acidification-could-impacts-atlantic-cod-populations-more-severely-than-previously-thought/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[2017 currently holds the record for hottest ocean temperatures, but, according to a new study, 2018 is likely to take the top spot as hottest year on record for Earth’s oceans as global warming’s impacts accelerate. Thanks to the Argo ocean observation system, a network of autonomous floats that was deployed in the early 2000s, we now have much greater capacity for monitoring ocean temperatures. At the same time, researchers have been steadily improving our understanding of long-term ocean heat content trends by correcting for biases and errors in previous analyses of the existing pre-Argo data. The result is that it is now possible to reconstruct the ocean temperature record all the way back to 1960 with a high degree of accuracy, according to Dr. Lijing Cheng of the Institute of Atmospheric Physics at the Chinese Academy of Sciences. Cheng led a research team that combined new observations enabled by the Argo network with the adjusted data from the past to show that ocean warming is accelerating at a rapid pace and will continue to do so unless we draw down greenhouse gas emissions. The team’s findings were detailed in a paper published in Science today. The mean speed of ocean warming over the past 60 years, from roughly 1958 to 2017, was 5.46 zettajoules per year, Cheng told Mongabay, which is more ocean warming than was reported in the Intergovernmental Panel on Climate Change&#8217;s Fifth Assessment Report, published in 2013.
