Warming-Stoked Eating Huge Holes In Greenland Glacier

Published

Greenland –

Daily tides fueled by warmer water ate a hole taller than the Washington Monument to the bottom of one of Greenland’s biggest glaciers in the last several years, hastening the glacier’s retreat, according to new research.

Scientists are concerned that the occurrence is not isolated to just one glacier, calling into doubt prior estimates of melting rates on the world’s vulnerable ice sheets.

The rapid melt seen in this study occurred on Petermann Glacier in Greenland’s extreme northwest. If this happens throughout the rest of Greenland and the even larger Antarctic ice sheet, global ice loss and sea level rise could accelerate up to twice as quickly as previously estimated, according to a study published in the Proceedings of the National Academy of Sciences on Monday.

“It’s bad news,” said research author and glaciologist Eric Rignot of the University of California, Irvine. “We recognize that the present predictions are overly conservative. We know they will have a difficult time matching the current melt record.

He stated that the newly discovered effect of tidal activity “could potentially double the projections” of global melt.

The study focuses on the critical grounding line area of glaciers on ice sheets. This is the point at which glaciers transition from being on land to floating on the sea. Previous research indicates that it is also a hotspot for rapid ice loss.

The grounding line zone at rural Petermann, where few people have gone and no base camps, is more than six-tenths of a mile (1 kilometer) wide and might be as much as 3.7 miles (6 kilometers) wide, according to the study.

Scientists used to believe that daily tides had little impact on the melt. Rignot claimed the day before leaving for an expedition to Petermann that the snow dumped on top of the glacier compensated for the tides pushing further in.

The rapid melt seen in this study occurred on Petermann Glacier in Greenland’s extreme northwest.

However, in Greenland with a warmer ocean due to climate change, tides have become “a very powerful mechanism,” according to Rignot.

“The seawater goes much farther beneath the grounded ice (than previously thought), kilometers, not hundreds of meters,” Rignot added. “And that water is hot enough to melt the glaciers quickly.” And it’s also the glacier’s most vulnerable area.”

Rignot’s team discovered a 669-foot-tall (204-meter) hollow near the grounding line using satellite altitude readings, where the melt rate had been 50% higher in the previous three years than from 2016 to 2019. Previous models predicted no melting there.

Rignot hypothesized that the melting in Petermann has intensified in recent years, later than in the rest of Greenland, since it is so far north that the water melting it from beneath is from the North Atlantic, and it takes longer for the warmer water to arrive there.

Rignot is investigating Petermann this month to obtain further ground-based data utilizing ultrasonography. He last arrived in 2006, a decade before satellites revealed the alterations. When Rignot visited Petermann before the glacier’s retreat increased, he noted motions that made it appear alive.

“When you are standing on that shelf or sleeping on that shelf, you hear noises all the time, loud noises from deep inside cracks forming,” Rignot explained. “That’s when the idea of a glacier being alive starts to sink in.”

Jason Box of the Geological Survey of Denmark and Greenland, who was not involved in the study, praised Rignot’s technique and stated the work made sense, demonstrating “that ocean heat delivery to tidewater glacier grounding lines represents a potentially destabilizing effect.”

Box calculates 434 billion metric tonnes of ice on Petermann is already committed to melting using a new technique called “zombie ice,” which employs a different technique to quantify how much ice is no longer being fed by glaciers and is bound to melt.

According to Pennsylvania State University glaciologist Richard Alley, who was not involved in the Rignot study, “The study provides strong evidence that models need to include these tidal effects deep inland, and if they don’t, they are underestimating future sea level rise.”

Argentina Asks To Join NATO As President Milei Seeks A More Prominent Role For His Nation

BUENOS AIRES, Argentina – Argentina formally sought on Thursday to join NATO as a worldwide partner, paving the stage for further political and security cooperation at a time when President Javier Milei’s right-wing government seeks to strengthen ties with Western powers and attract investment.

The request came as NATO Deputy General Secretary Mircea Geoana met with visiting Argentine Defense Minister Luis Petri in Brussels to discuss regional security problems.

Argentina Asks To Join NATO As President Milei Seeks A More Prominent Role For His Nation

Geoana said he supported Argentina’s bid to become an accredited partner in the alliance, which is a valuable role short of “ally” for nations outside NATO’s geographical territory and not compelled to participate in joint military actions. NATO membership is currently confined to European countries, Turkey, Canada, and the United States.

The classification may provide Argentina with access to modern technology, security systems, and training that it did not previously have, according to the Argentine presidency.

“Argentina plays an important role in Latin America,” Geoana stated at NATO headquarters. “Closer political and practical cooperation could benefit us both.”

Milei has been promoting a radical libertarian agenda aimed at undoing years of protectionist trade policies, overspending, and debilitating international debt that have thrown the country’s economy into disarray.

Argentina Asks To Join NATO As President Milei Seeks A More Prominent Role For His Nation

Over the last four months as president, he has reshaped Argentina’s foreign policy to one of almost unconditional support for the United States, as part of an effort to restore Argentina’s global economic prominence after previous administrations allowed relations with Washington and European allies to deteriorate.

Milei’s government is likewise looking for security gains from improved ties with Western countries. On Thursday, the US government revealed that it would provide Argentina with $40 million in foreign military financing for the first time in more than two decades, allowing critical US allies such as Israel to purchase American weapons.

The money, meant to assist Argentina equip and modernize its military, will help cover the cost of 24 American F-16 fighter aircraft purchased from Denmark earlier this week. Defense Minister Petri described the acquisition of the upgraded jets as “the most important military purchase since Argentina’s return to democracy” in 1983. Milei’s political opponents have criticized the $300 million price tag, which comes as he lowers government expenditure.

Formal partnership with NATO requires the agreement of all 32 NATO countries. Argentina’s relations with crucial NATO partner Britain have been strained since 1982, when the two went to war over the disputed Falkland Islands in the South Atlantic.

The Alliance’s other global partners include Afghanistan, Australia, Iraq, Japan, the Republic of Korea, Mongolia, New Zealand, and Pakistan. Colombia is now NATO’s lone partner in Latin America.

Giving a country the title of “global partner” does not guarantee that NATO allies will defend it in the case of an attack. That pledge, outlined in Article 5 of the North Atlantic Treaty Organization’s founding treaty, is limited to full members of the alliance.

NATO’s conversation with Argentina began in the early 1990s. Former President Bill Clinton labeled Argentina a “major non-NATO ally” in 1998, partly as a symbolic gesture to reward the pro-American government at the time for contributing soldiers on peacekeeping operations in Bosnia.

The prosecutors claimed that close cooperation with Ukrainian prosecutors and security agencies, who tipped them off and provided crucial evidence, made the arrest possible. They stated the case is progressing.

On Thursday, prosecutors in Germany announced the arrest of two German-Russian individuals on suspicion of espionage, with one accused of agreeing to carry out assaults on potential targets, including US military bases, in the hopes of damaging supplies to Ukraine.

Dieter S. and Alexander J. were arrested Wednesday in Bayreuth, Bavaria, according to German federal authorities.

Since Moscow initiated its campaign on Ukraine in February 2022, several persons have been arrested in Poland on suspicion of spying for Russia, including a dual Russian-Spanish citizen.

TAIPEI, Taiwan — The U.S. 7th Fleet reported that a Navy P-8A Poseidon flew through the Taiwan Strait on Wednesday, a day after U.S. and Chinese defense leaders conducted their first discussions since November 2022 to ease regional tensions.

The patrol and reconnaissance jet “transited the Taiwan Strait in international airspace,” according to a 7th Fleet news release.

US Navy Flies Aircraft Through The Taiwan Strait A Day After US – China Defense Chiefs Hold Rare Talks

The statement stated, “By operating within the Taiwan Strait in accordance with international law, the United States upholds the navigational rights and freedoms of all nations.”

The vital strait, 160 kilometers (100 miles) wide, separates China from the self-governing island democracy. Although it is on the international seas, China regards the passage of foreign military aircraft and ships through it as a threat to its sovereignty.

China claims Taiwan and has threatened to protect it with force if necessary, despite U.S. military support for the island.

According to a report on the Chinese People’s Liberation Army’s Eastern Theater Command’s official Weibo social media site, China dispatched fighter jets to “monitor the U.S. plane’s passage” and operated “in accordance with laws and regulations.”

“Theater troops are on high alert at all times to resolutely safeguard national sovereignty and security as well as regional peace and stability,” Li said in a statement.

China often issues severe protests and deploys fortifications in reaction to the passage of ships and military planes across the Straight, particularly those from the United States.

China also regularly deploys navy ships and airplanes into the strait and other locations around the island to wear down Taiwan’s defenses and scare its 23 million people, who staunchly support their de facto independence.

“By operating in the Taiwan Strait in conformity with international law, the United States protects all nations’ navigational rights and freedoms. The aircraft’s passage through the Taiwan Strait underlines the U.S. commitment to a free and open Indo-Pacific. According to the 7th Fleet statement, the United States military flies, sails, and operates wherever international law allows.

U.S. Defense Secretary Lloyd Austin spoke with his Chinese counterpart, Adm. Dong Jun, on Tuesday in the latest move to strengthen relations with the Chinese military and lessen the likelihood of a regional conflict.

It was Austin’s first time speaking with Dong and his first time speaking in depth with any Chinese counterpart since November 2022. The call lasted slightly more than an hour, as U.S. Secretary of State Antony Blinken will visit China this month for discussions.

Military-to-military contact ended in August 2022 when Beijing terminated all communication following a visit by then-House Speaker Nancy Pelosi to Asia. China replied by firing missiles over the country and increasing military exercises, including what seemed to be a rehearsal for a naval and aerial blockade of the island.
