The startup company, Arctic Ice, shipped its first container of around 22 tons of Greenland ice to Dubai this year for sale to high-end bars and restaurants. Founded in 2022 by two Greenlanders, Arctic Ice has an interesting — and controversial — business model. Arctic Ice claims it’s offering a novel way to harness a natural resource, carving out new economic opportunities and raising awareness of the Arctic. Various attempts have been made over the past few decades to bring back natural ice commercially, but with little success. But perhaps inevitably for a business model that involves shipping a diminishing natural resource halfway across the world, Arctic Ice has attracted controversy.

CNN —The area of Greenland’s ice loss in the past three decades is roughly 36 times the size of New York City — land that is rapidly giving way to wetlands and shrubs, a study published Tuesday shows. Ice loss has exposed barren rock in parts of the country. Mark Smith/University of LeedsWarmer air temperatures have driven ice loss, which has in turn raised land temperatures. Snow and ice typically reflect the sun’s energy back into space, preventing excessive heating in parts of the Earth. Ice melt also increases the amount of water in lakes, where water absorbs more heat than snow, which increases land surface temperatures.

Greenland’s expansive ice sheet is known to be shrinking, especially since the 1990s, because of warming from climate change. It’s a fate shared by the Antarctic Ice Sheet as well as glaciers around the world. Now, a new study reveals that about 20 percent more of the Greenland ice sheet has disappeared than previous estimates show. The missing ice has been breaking and melting from the ends of glaciers around Greenland’s perimeter. “Almost every glacier in Greenland is retreating.

Now housed in the Danish National Archives, the historical images inspired her and other researchers to reconstruct the territory’s glacial history and how it has changed amid a rapidly warming climate. The comparison found Greenland’s glaciers have experienced an alarming rate of retreat that has accelerated over the last two decades. For the first time on record, it rained at the summit of Greenland — roughly two miles above sea level during the summer of 2021. Earlier this week, scientists found that northern Greenland’s huge glaciers, which were long thought to be relatively stable, now pose potentially “dramatic” consequences for sea level rise. “[The paper] really reinforces that our choices over the next few decades and how much we reduce our emissions really matter to these glaciers,” Larocca said.

Greenland’s mountain glaciers and floating ice shelves are melting faster than they were just a few decades ago and becoming destabilized, according to two separate studies published this week. The island's peripheral glaciers, located mostly in coastal mountains and not directly connected to the larger Greenland ice sheet, retreated twice as fast between 2000 and 2021 as they did before the turn of the century, according to a study published on Thursday. “It got a lot harder to be a glacier in Greenland in the 21st century than it had been even in the 1990s,” said Yarrow Axford, a professor of geological sciences at Northwestern University and a co-author of the paper, published in the journal Nature Climate Change. Dr. Axford’s team found that glaciers in southern Greenland have become shorter by 18 percent on average since 2000, and glaciers elsewhere on the island have become shorter by 5 to 10 percent.

CNN —At the top of the world, northern Greenland’s huge glaciers — long thought to be relatively stable — are in trouble, a new study shows. As the ocean warms, Greenland’s last remaining ice shelves are rapidly weakening, destabilizing the nearby glaciers and threatening potentially “dramatic” consequences for sea level rise, according to the study published Tuesday in Nature Communications. When they melt and weaken, more of the land-based ice is able to slide into the ocean, adding to sea level rise. Since 1978, the ice shelves supporting northern Greenland’s glaciers have lost more than 35% of their total volume, according to the study. After the collapse of the Zachariæ Isstrøm glacier’s ice shelf in 2003, the ice discharge into the ocean doubled, according to the study.

A luxury cruise ship carrying 206 passengers and crew members has been stuck in the cold northern waters of Greenland since Monday after it ran aground. The ship — named the Ocean Explorer and operated by Aurora Expeditions, a cruise company based in Australia — had been traveling toward Alpefjord, which is in a remote corner of Greenland. Its destination was the Northeast Greenland National Park, which is the northernmost national park in the world and is home to icebergs, glaciers and high mountains. The Joint Arctic Command, which is part of Denmark’s defense forces, said on Facebook on Tuesday that there were no injuries on board the Ocean Explorer and that there is no threat to the environment. On Wednesday, a fishing research vessel owned by the government of Greenland tried unsuccessfully to pull the Ocean Explorer at high tide.

In 2021, along a two-lane highway in Mandan, N.D., a giant billboard showing masked figures in clothing that was inspired by both Indigenous tradition and science fiction declared: “WE SURVIVE YOU.” Its artist, Cannupa Hanska Luger, is one of 17,000 members enrolled in the Mandan, Hidatsa and Arikara Nations today. In 2007, the Anishinaabe artist Rebecca Belmore photographed an Indigenous woman with a “fringe” of blood (represented by red string) trickling from a diagonal scar across her back. “To me it is a wound that is on the mend,” Belmore has said. “She will get up and go on, but she will carry that mark with her.”Over the years, the Kalaaleq artist Laakkuluk Williamson Bathory has performed Greenlandic mask dances, or uaajeerneq, for audiences around the world: “It is a fearsome, sexy clown act,” she’s written, “that was handed down to me from my mother and other Inuit activist artists from Greenland’s movement to self-government in the 1970s.”

Instead, moderate, natural warming led to large-scale melting and sea level rise of more than 1.4 meters (4.6 feet), according to the report published Thursday in the journal Science. This would have significant impacts on sea level rise. The potential implications for sea level rise are enormous, Tammy Rittenour, a professor from Utah State University and study co-author said in a statement. “We are looking at meters of sea level rise, probably tens of meters. “The current greenhouse gas emission-driven warming may reduce the Greenland ice sheet faster than forecast,” he told CNN.

CNN —A major glacier in northwest Greenland is interacting with the ocean tides, scientists reported Monday, resulting in previously unaccounted-for melting and potentially faster sea level rise. This is an important finding: The traditional view among scientists was that the grounding line did not migrate with the tides – and this introduces another major source of melting that could be accelerating sea level rise. Between 2016 and 2022, warmer tidal cycles melted a 670-foot-tall hole in the underside of the glacier along the grounding line — big enough that two Statues of Liberty could be stacked on top of one another inside it. The study raises more concerns for the already worrisome prospect of sea level rise, which threatens coastlines around the world. Greenland’s melting ice is the single largest contributor to sea level rise, according to NASA, which has been accelerating in recent years.
CNN —The Earth’s ice sheets lost enough ice over the last 30 years to create an ice cube 12 miles high, according to new research. They found that ice sheet melting has increased six-fold over the past 30 years, as record levels of planet-heating pollution push up global temperatures. The worst year for ice sheet loss was 2019, the report found, when the ice sheets lost around 675 billion tons of ice. Ice sheet melting now accounts for a quarter of all sea level rise – a fivefold increase since the 1990s. Otosaka expects the Greenland ice sheet to continue losing ice, but said it’s not yet clear what might happen to the Antarctic ice sheet.
SHORT TERM FLUCTUATIONSGlobal surface temperatures are heavily influenced by annual Pacific Ocean patterns known as El Nino and La Nina, and collectively as ENSO (El Niño–Southern Oscillation). A large El Nino event followed by a La Nina can “lead to a temporary ‘pause’ in global temperatures over timescales of a decade or so”, Hausfather said. This is “what we are now seeing after the 2015/2016 super El Nino event”. Whenever there is a trend with variability like global temperatures, “you can isolate cherry-picked intervals and claim that something has paused or accelerated, but this is not appropriate”, Colose said. Temperature data for the past eight years do not reflect long-term trends, experts say, and longer-term data clearly show a continuing rise in overall global temperatures.
CNN —A core of ice age sediment from northern Greenland has yielded the world’s oldest sequences of DNA. They then compared the DNA fragments with existing libraries of DNA collected from both extinct and living animals, plants and microorganisms. It was super exciting when we recovered the DNA (to see) that very, very different ecosystem. They found no DNA from carnivores but believe predators — such as bears, wolves or even saber-toothed tigers — must have been present in the ecosystem. Further study of environmental DNA from this time period could help scientists understand how various organisms might adapt to climate change.
Lewis Pugh had to contend with large shipping vessels while swimming across the Red Sea. Pugh completed his swim across the Red Sea -- home to some of the world's most biodiverse coral reefs -- in 16 days. The Lewis Pugh FoundationFor sections of the swim, Pugh was joined by open-water swimmer Mariam Saleh Bin Laden – who became the first Arab, first Saudi and first woman to swim from Saudi Arabia to Egypt – and Egyptian swimmer Mostafa Zaki. The purpose of the swim was to shine a spotlight on the world’s coral reefs – home to the earth’s most vibrant marine ecosystems – and their precarious status amid the climate crisis. The Lewis Pugh FoundationThis week, Pugh has traveled to the COP27 climate summit in Sharm El-Sheikh, Egypt – a location he passed during his swim across the Red Sea.

The much higher asking price 18 months ago for the downtown Los Angeles apartment building was less than Greenland’s development costs. A major Chinese developer on Tuesday disposed of the tallest rental apartment tower in downtown Los Angeles at a steep loss, the latest in a recent wave of Chinese investors unloading prized U.S. real-estate assets. The U.S. subsidiary of China’s Greenland Holding Group sold the 59-story apartment skyscraper for $504 million, according to the buyer, privately held apartment owner Northland.

How do we weigh the risks of underreacting to climate change against the risks of overreacting to it?

That’s particularly true if climate change is akin to cancer — manageable or curable in its earlier stages, disastrous in its later ones.

But sea levels have been rising for 100 years in Baltimore.”ROCKET SCIENCEThe irony is evident at Wallops Flight Facility. Yet this bastion of climate research has been slow to apply the science of sea level rise to its own operations. Reviewers from state and federal agencies criticized the 348-page document for failing to adequately take rising sea levels into account in the project design and impact, or to temper future plans for expansion. Joshua Bundick, Wallops’s environmental planning manager, explained that he distilled the issues “down to only the highest points,” and sea level rise wasn’t among them. The cost to American taxpayers of repeated destruction of the parking lot and causeway from rising sea levels would only increase, Fish and Wildlife officials said.
