Colliding icebergs and chirping seals: Polar ocean sounds are reimagined in art-science collaboration
- The United Nations declared the 2020s the UN Decade of Ocean Science for Sustainable Development to highlight the need for public engagement, citizenship, and connection to harness positive change for the world’s seas.
- Art and science collaborations can make the hidden depths of the oceans come alive for people via creative pieces drawing from real marine research.
- Researchers in Germany and artists from around the world united to highlight the sounds of the polar oceans through art projects created with recordings from the Ocean Acoustics Group at the Alfred Wegener Institute.

Killer whales have found new homes in the Arctic Ocean, potentially reshaping marine ecology
- The vast ice sheets that historically kept killer whales out of the Arctic Ocean are melting as the region rapidly warms.
- Two small, genetically distinct groups of killer whales now live in the Arctic, after migrating from more southern regions of the Atlantic Ocean.
- Killer whales put pressure on the local ecosystem, including Arctic whales important to Indigenous groups.

The new Arctic: Amid record heat, ecosystems morph and wildlife struggle
- Every species of animal and plant that lives or breeds in the Arctic is experiencing dramatic change. As the polar region warms, species endure extreme weather, shrinking and altered habitat, decreased food availability, and competition from invading southern species.
- A wide array of Arctic organisms that rely on sea ice to feed or breed during some or all of their life cycles are threatened by melt: Over the past 40 years, the Arctic Ocean has lost about 75% of its sea ice volume, as measured at the end of the summer melt season. This translates into a loss of sea ice extent and thickness by half on average.
- Researchers note that the rate of change is accelerating at sea and on land. While species can adapt over time, Arctic ecosystem alterations are too rapid for many animals to adapt, making it difficult to guess which species will prevail, which will perish, and where.
- The only thing that could limit future extinctions, researchers say, is to quickly stop burning fossil fuels, the main driver of climate change.

North Atlantic orcas reveal the troubling persistence of toxic ocean pollutants
- As the top predators in the ocean, killer whales suffer from the magnifying level of pollutants that build up in the marine food web.
- Scientists found that North Atlantic orcas feeding on marine mammals carry significantly higher levels of pollutants than orcas that eat fish.
- Levels of polychlorinated biphenyls in the orcas’ blubber are ten times higher than the toxic threshold for these dangerous household chemicals.

‘Not a good sign’: Study shows Greenland temperatures at 1,000-year high
- New research shows that north-central Greenland experienced the highest temperatures between 2001 and 2011 over a 1,000-year period.
- Scientists came to this conclusion after reconstructing climate conditions over the last millennium by analyzing ice cores from the Greenland ice sheet.
- This study can provide a foundation for future studies on ice melt and sea level rise, the authors say.

Greenland shark, world’s longest-living vertebrate, gets long-awaited protection
- In September, the Northwest Atlantic Fisheries Organization (NAFO), an intergovernmental organization that manages fisheries, prohibited the retention of Greenland sharks in international waters.
- This ban would apply to the intentional catching of Greenland sharks as well as the retention of the species as bycatch.
- However, bycatch exceptions could be made if countries prohibit the discarding of fish.
- Greenland sharks are known to be the longest-living vertebrate in the world, reaching ages of between 270 and 500 years.

Greenland’s Indigenous population favors extracting sand from melting ice sheet
- In 2022, the Greenland ice sheet experienced net ice loss for the 26th year in a row. But that loss is producing a potentially valuable resource: sand, which the melting ice sheet is depositing on the coast.
- Together, sand and gravel are one of the most traded commodities in the world, and a study by researchers at McGill University found that the majority of Greenlanders, including Indigenous people, supported extracting sand for export.
- But Greenlanders—who have staunchly opposed some mining projects in the past—say this activity needs to be done with adequate environmental protection and consultation of Greenland’s predominantly Indigenous population.
- The environmental consequences are uncertain but could include impacts from sucking sand off the substrate and increasing shipping traffic.

With sea ice melting, glacial ice could be a lifeline for polar bears
- Scientists recently discovered a new subpopulation of polar bears living in southeast Greenland that is genetically and behaviorally distinct.
- While most polar bears depend upon sea ice for survival, the polar bears in Southeast Greenland use pieces of glacial ice as habitat and hunting platforms.
- Large numbers of polar bears are expected to decline as climate change accelerates, but small populations may persist in places like this, where the pace of melting is expected to be slower, experts say.

As Arctic warms, scientists wrestle with its climate ‘tipping point’
- A leaked version of the newest science report from the U.N. Intergovernmental Panel on Climate Change warns of looming, potentially catastrophic tipping points for Arctic sea ice melt, tundra thaw, savannification of the Amazon rainforest, and other planetary environmental thresholds beyond which recovery may be impossible.
- But what are tipping points, and how does one pinpoint what causes them, or when they will occur? When studying a vast region, like the Arctic, answering these questions becomes dauntingly difficult, as complex positive feedback loops (amplifying climate warming impacts) and negative feedback loops (retarding them) collide with each other.
- In the Arctic, one working definition of a climatic tipping point is when nearly all sea ice disappears in summer, causing a Blue Ocean Event. But attempts to model when a Blue Ocean Event will occur have run up against chaotic and complex feedback loop interactions.
- Among these are behaviors of ocean currents, winds, waves, clouds, snow cover, sea ice shape, permafrost melt, subarctic wildfires, aerosols and more, with many interactions still poorly understood. Some scientists say too much focus is going to tipping points, and research should be going to the “radical uncertainty” of escalating extreme local events.

‘Red-carded’ Australian miner signals intention to play on in Greenland
- The advancement of a huge rare earths and uranium mining project in Greenland sparked a snap election in April that saw a green party elected and a new government formed that is opposed to the mine.
- The Kvanefjeld project, developed by small Australian mining company Greenland Minerals Limited, with Chinese partner Shenghe Resources, would exploit one of the world’s largest deposits of rare earth metals and uranium near the small township of Narsaq and increase Greenland’s greenhouse gas emissions by 45%.
- While new coalition partners Inuit Ataqatigiit (Party for the People) and Naleraq campaigned against the mine and have a written agreement opposing any uranium mining in Greenland, the consultation process for Kvanefjeld is continuing, and NGOs are concerned that Greenland Minerals will try to pressure the new government to agree to the project in some form.
- In early July, Greenland’s Ministry of Mineral Resources released a draft bill banning uranium mining and exploration and limiting the amount of uranium present as a by-product in any mining operations to 100 parts per million — which would prevent the Kvanefjeld operation going ahead.

Arctic biodiversity at risk as world overshoots climate planetary boundary
- The Arctic Ocean biome is changing rapidly, warming at twice the rate of the rest of the world. In turn, multiyear sea ice is thinning and shrinking, upsetting the system’s natural equilibrium.
- Thinner sea ice has led to massive under-ice phytoplankton blooms, drawing southern species poleward; fish species from lower latitudes are moving into the peripheral seas of the Arctic Ocean, displacing and outcompeting native Arctic species.
- Predators at the top of the food chain, such as polar bears, are suffering the consequences of disappearing ice, forced onto land for longer periods of time where they cannot productively hunt.
- The Central Arctic Ocean Fisheries Agreement has been signed by 10 parties to prevent unregulated commercial fishing in the basin until the region and climate change impacts are better understood by scientists. International cooperation will be critical to protect what biodiversity remains.

We’re approaching critical climate tipping points: Q&A with Tim Lenton
- Over the past twenty years the concept of “tipping points” has become more familiar to the public. Tipping points are critical thresholds at which small changes can lead to dramatic shifts in the state of the entire system.
- Awareness of climate tipping points has grown in policy circles in recent years in no small part thanks to the work of climate scientist Tim Lenton, who serves as the director of the Global Systems Institute at Britain’s University of Exeter.
- Lenton says the the rate at which we appear to be approaching several tipping points is now ringing alarm bells, but “most of our current generation of politicians are just not up to this leadership task”.
- The pandemic however may have caused a shock to the system that could trigger what he calls “positive social tipping points” that “can accelerate the transformative change we need” provided we’re able to empower the right leaders.

The glaciers of the Greenland Ice Sheet are running away
- Greenland’s massive ice sheet will continue shrinking even if snowfall rates return to the higher levels of decades ago, when the ice sheet was stable, a new study shows.
- Rates of ice loss climbed dramatically in the early 2000s before settling at a higher, sustained state of decline.
- For each kilometer that Greenland’s glaciers retreat, their rate of ice loss speeds up by 4 to 5 percent—a bleak trend that will accelerate sea-level rise.

Ice breakers in the Arctic: Let’s talk Inuit safety (commentary)
- A little-considered impact of warming temperatures in the Arctic is the increased activity of ice breakers.
- Martin Robards, Regional Director for the Arctic Beringia Program at the Wildlife Conservation Society, and Beverly Maksagak, Manager of the Ekaluktutiak Hunters and Trappers Organization, write that ice breakers potentially pose a threat to traditional Inuit ways of life.
- Robards and Maksagak write about the Proactive Vessel Management (PVM) initiative, which last year brought together communities, industry, and vessel operators find solutions to issues of concern on Arctic waterways.
- This post is a commentary: the views expressed are those of the author, not necessarily Mongabay.

Brave New Arctic: Sea ice has yet to form off of Siberia, worrying scientists
- After a summer that saw record Siberian fires and polar temperatures topping 100 degrees Fahrenheit, along with near record low sea ice extent in September, the Arctic Ocean’s refreeze has slowed to a crawl.
- The Laptev Sea and East Siberian Sea are, at this point, failing to re-freeze as rapidly as in the past. Scientists see all of these worrying events, along with many other indicators including fast melting permafrost, as harbingers of a northern polar region that may be entering a new climate regime.
- Models predict the Arctic will be ice-free in summer by 2040 or 2050, with unforeseen negative impacts not only in the Far North, but on people, economies and ecosystems around the globe. One major concern: scientists worry how changes in the Arctic might alter temperate weather systems, impacting global food security.
- “We’re conducting this blind experiment, and we don’t yet know the real implications,” one sea ice researcher tells Mongabay. “How do you sell climate change to be as much of an emergency as COVID-19? Except that it will kill a lot more people.”

Arctic Sea ice melts to second-place finish at annual minimum
- At the annual September Arctic sea ice minimum this year, the ice extent was reduced to just 3.74 million square kilometers, a low that surpassed every year since 1979 except 2012, which saw a minimum of 3.41 million square kilometers.
- While 2012 was an anomaly (a year in which an immense August cyclone shattered the weakened ice), 2020 came very close to that record, but without any such storm, though the region did see intense July and August heat.
- A new study finds, once again, that what starts in the Arctic doesn’t stay there. Researchers say that Asia is seeing lengthier bouts of extreme storms, droughts, heat and cold as weather systems stall there, possibly due to a weakening Northern Hemisphere jet stream — an effect thought to be due to Arctic warming.
- In other new research, scientists say a layer of warm Atlantic water entering the Arctic, which had always stayed down deep in the past, is starting to rise toward, and mix with, colder surface waters. That mixing could be fatal to the Arctic sea ice in the future — with unknown, but potentially dire impacts on global climate stability.

Climate conundrum: Could COVID-19 be linked to early Arctic ice melt?
- The COVID-19 pandemic has yielded unexpected environmental benefits, as wildlife explore urban streets and 2020 carbon emissions drop by the largest amount since World War II. But now researchers are wondering if a record hot and sunny start to the Arctic sea ice melt season could be linked to the Coronavirus lockdown.
- The possible cause: a reduction in atmospheric sulphate aerosol pollutants emitted by factories, ships and other sources. Sulphate aerosols increase the amount of clouds and brighten the atmosphere, reflecting more solar heat, thus masking global warming intensity — and making the Arctic cloudier and colder.
- Scientists are working to determine if, and by how much, sulphate aerosols have declined due to the industrial slowdown brought by the COVID-19 pandemic.
- These figures could help them more precisely determine how aerosols have been inhibiting atmospheric heating around the world, especially in the Arctic. One study found that sulphate aerosol-seeded clouds could be masking about a third of all warming from greenhouse gases. However, the question is far from settled.

2019 in line for second lowest Arctic sea ice extent record
- 2019 has seen constant heat and melt conditioning of the Arctic sea ice, resulting in record, and near record, daily and monthly extent and volume stats over much of the melt season. The average volume for July, for example, fell to 8,800 cubic kilometers (2,111 cubic miles), a new record low.
- Whether 2019 will set a new all-time extent or volume record at the September sea ice minimum remains to be seen, with ice extent shrinking less quickly since mid-August, possibly putting this year in second place, though certainly among the top five record lowest minimums.
- The big news this year was the relentless heat in the Arctic, with record heat waves over Alaska, Scandinavia and Greenland, resulting in massive glacial runoff into the sea. Wildfires were rampant, with reindeer and fish including salmon possibly adversely impacted by very hot air and water temperatures.
- Whether or not 2019 sets a new sea ice extent or volume low record this September is incidental. What this year dramatically showed is that the climate crisis has anchored itself firmly in the Arctic, and shows no signs of easing over the long-haul.

More than 50 lakes lie hidden beneath Greenland ice sheet, study finds
- Scientists say they’ve identified 56 lakes beneath the Greenland ice sheet, bringing the total to 60 known subglacial lakes underneath the thick ice mass.
- While some of these lakes are just 200 meters (650 feet) long, some are nearly 6 kilometers (3.7 miles) in length.
- There are probably many more such subglacial lakes under the Greenland ice sheet waiting to be uncovered, the researchers say.

Agreement bans commercial fishing across much of the Arctic, for now
- Nine jurisdictions — Canada, Norway, Russia, the U.S., China, Iceland, Japan, South Korea, Denmark (including Greenland and the Faroe Islands) and the European Union — have signed a legally binding agreement that bans commercial fishing in the high seas portion of the Central Arctic Ocean, covering 2.8 million square kilometers, or an area about the size of the Mediterranean Sea, for at least 16 years.
- As part of the agreement, the signatory parties have committed to a joint scientific research and monitoring program to gain a better understanding of the changing Arctic ecosystem and determine the region’s potential for commercial, sustainable fisheries in the future.
- The moratorium will initially cover 16 years, but this can be extended in five-year increments, if the parties agree to do so.

The Arctic’s oldest, thickest ice is breaking up
- Strong southerly winds pushed sea ice away from Greenland’s north coast twice this year — a possible first.
- We’re unlikely to see a new record sea ice extent minimum in the Arctic Ocean come September 2018. Sea ice extent in the Arctic is currently clocking in at 5.396 million square kilometers (about 2.1 million square miles). That’s the good news.
- But the melt-out above Greenland has alarming implications for the future. If even the thickest, oldest ice is now susceptible to increased warming and changes in weather, what hope is there for the rest of the Arctic?

Audio: Bowhead whales in the Arctic sing hundreds of complex songs
- Scientists have recorded 184 elaborate, very different bowhead whale songs in a bowhead subpopulation living east of Greenland. This makes it the largest set of bowhead whale song recordings ever.
- The bowhead’s vocal repertoire is rivaled only by a few species of songbirds, researchers say.
- But why these whales have so many different song types and why they change their songs each year is still a mystery.

Abnormal Arctic ice season may signal abrupt climate change
- A so-called “Blue-Ocean Event” — a period during the melt season with less than 1 million square kilometers (a little over 386,100 square miles) of Arctic sea ice — was not expected to occur until 2070 to 2100 by most science modeling projections of the early 21st Century.
- Recent polar ice observations, however, indicate extreme loss of volume. Daily sea ice loss rates since late April 2016 have averaged about 75,000 square kilometers (about 29,000 square miles) per 24 hours, resulting in continuously record low levels.
- Many climate scientists now project the first “Blue-Ocean Event” within a decade or less. Some experts speculate it may even occur during the melt season of 2016.

New dams may expose Canadian seafood consumers to higher levels of neurotoxin
- Methylmercury, a dangerous neurotoxin, can build up in the bodies of marine mammals and fish, threatening the humans who eat them.
- New research suggests dams and reservoirs in sub-Arctic regions may release methylmercury downstream.
- Native residents who depend on hunting and fishing are especially at risk.

Scientists can now accurately count polar bears…from space

Polar bears are big animals. As the world’s largest land predators, a single male can weigh over a staggering 700 kilograms (about 1,500 pounds). But as impressive as they are, it’s difficult to imagine counting polar bears from space. Still, this is exactly what scientists have done according to a new paper in the open-access […]
Climate change’s ominous secret

Climate change is happening and humans are causing it, primarily from the increase in atmospheric carbon dioxide caused by burning fossil fuels. This much we know. The “secret” comes from changes happening in the fast-warming Arctic: we may be surprisingly close to an Earth that supports far fewer humans than it does today. Permafrost and […]
