Warming-Stoked Eating Huge Holes In Greenland Glacier

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.”

train

NEW DELHI — At least 50 people were killed, and hundreds more were trapped inside more than a dozen damaged rail cars when two passenger trains in India crashed on Friday, according to officials.

According to officials, the disaster occurred in eastern India, around 220 kilometers (137 miles) southwest of Kolkata, and about 400 people were sent to hospitals. The cause was being looked into.

Amitabh Sharma, a spokesman for the railway ministry, reported that ten to twelve coaches of one train derailed, and pieces of some of the damaged coaches fell onto an adjacent track.

According to Sharma, a passenger train traveling the other way struck the debris, and up to three coaches of the second train also derailed.

According to the Press Trust of India news agency, a third goods train was reportedly apparently involved, but there was no immediate confirmation from railway authorities.

Television photos from the aftermath showed rescuers scaling the rubble to pry open doors and windows and use cutting torches to free trapped survivors.

A passenger train traveling the other way struck the debris, and up to three coaches of the second train also derailed.

Vandana Kaleda, a passenger, said to the New Delhi Television news station that she “found people falling on each other” as her carriage shook erratically and deviated from the lines. She claimed that her survival was fortuitous.

Another survivor, who wished to remain anonymous, claimed that the impact woke him up while he was asleep. He claimed to have observed other people with damaged faces and shattered limbs.

At least 50 persons were reported dead, according to Balasore district’s senior administrator Dattatraya Bhausaheb Shinde. At least 70 people had died, according to The Press Trust.

According to Pradeep Jena, the state’s chief executive officer of Odisha, there were close to 500 police officers and rescue personnel at the scene, along with 75 ambulances and buses.

Rescuers were working to release 200 individuals who were thought to be trapped in the rubble, according to Shinde.

The Coromandel Express, which derailed, was traveling from Howrah in West Bengal state to Chennai, the state capital of southern Tamil Nadu, according to The Press Trust.

Narendra Modi, the prime minister of India, expressed sympathy for the deceased families.

Having spoken with the railway minister, Modi tweeted, “May the injured recover soon,” adding that “all possible assistance” was being provided.

Several hundred incidents happen annually on India’s railways, the world’s largest train network with single management, despite government efforts to increase rail safety.

The deadliest train catastrophe in Indian history occurred in August 1995 when two trains crashed close to New Delhi, killing 358 people.

Human mistakes or out-of-date signaling equipment are the main causes of trains accidents.

Every day, 14,000 trains carrying more than 12 million passengers traverse India’s 64,000 kilometers (40,000 miles) of railway.

Toyota Debuts Hydrogen-Fueled Corolla Race Car As Auto Racing Begins Shift Away From Gas In 2023

Published

on

toyota

Japan’s Oyama — A little Corolla powered by liquid hydrogen debuted in a vast circuit close to Mount Fuji as part of an initiative to introduce cutting-edge technology into the racing scene and showed Toyota’s commitment to creating eco-friendly cars.

Akio Toyoda, chairman of Toyota, was beaming as he prepared to drive the hydrogen-fueled Corolla around the track while clad in a fire-resistant racing costume.

“Racing using a liquid hydrogen automobile is a first for the world. In the effort to combat global warming, we hope it will present an additional choice. I want to run one lap, even one second further, to make everyone happy, declared Toyoda, a former Toyota CEO, the company’s founder’s grandson, and a licensed racer himself.

It will be soon that the hydrogen-powered Corolla race vehicle appears at your dealer. According to Toyota representatives, the Super Taikyu 24-hour race at Fuji Speedway was only a test for the technology.

Unlike electric vehicles, it has a combustion engine, but it burns liquid hydrogen rather than petrol.

Toyota Motor Corp., a Japanese carmaker that sells roughly 10 million vehicles annually, has lagged in the global transition to battery-powered electric vehicles (EVs), but it has long viewed hydrogen as a potentially carbon-neutral alternative.

Experts claim that hydrogen has enormous potential. However, most hydrogen produced to date has been used using fossil fuels like natural gas, including the hydrogen used to power the Corolla racing vehicle.

The need for alternative energy sources has become more urgent due to rising fuel prices and worries about global warming, particularly in Japan, where nearly all of its oil is imported.

Auto racing has been eschewing its gas-guzzling, snarling machines. Honda Motor Co., a rival of Toyota, has said it would resume competing in Formula One, citing the opportunity presented by the new regulations for developing new technology. General Motors Co. and other automakers have made comparable commitments.

Akio Toyoda, chairman of Toyota, was beaming as he prepared to drive the hydrogen-fueled Corolla around the track while clad in a fire-resistant racing costume.

The 24 Hours of Le Mans, the most prestigious endurance race in the world, will be available to hydrogen-powered vehicles utilizing both fuel cells and combustion engines beginning in 2026, according to an announcement made last week by Pierre Fillon, president of the Automobile Club de l’Ouest, the organization that puts on Le Mans.

For me, hydrogen is a very intriguing future solution, Fillon told reporters. “To achieve zero emissions, we must move. This is crucial for the environment and our future generations.

Toyota CEO Koji Sato stated that he planned to announce Toyota’s involvement in Le Mans soon.

John Heywood, an MIT professor emeritus and authority on automobile engines, noted that the conversation about green energy solutions has barely begun and that EVs also have disadvantages, such as the requirement for crucial minerals that are sometimes obtained in unethical or environmentally harmful ways.

There is nothing ‘ungreen’ about internal combustion engines. The fuel it utilizes is what counts, according to Heywood.

The hydrogen for Toyota’s race car is produced at an Australian coal gasification facility and distributed by the Japanese energy business Iwatani Corp. as part of a project supported by the Japanese government to encourage the use of hydrogen for various sectors, including those using fossil fuels.

Green hydrogen is produced when water is electrolyzed to separate its hydrogen and oxygen molecules. This happens when renewable energy sources drive an electrical current through water. The technique does not result in greenhouse gas carbon dioxide. However, the IEA estimates that fewer than 0.1% of the hydrogen produced globally is now produced this way.

According to critics, it could be preferable to use that renewable energy instead of converting it to hydrogen. However, proponents of hydrogen claim that when carbon emissions are captured and stored underground, even those created from natural gas can be environmentally good.

Sato recognized the difficulty.

“First, we must establish a setting conducive to employing hydrogen. “It’s important that the cycle of that system is working in all steps, including transporting it and making it, for hydrogen use to become widely used, and that environment must be stable,” he told reporters on the sidelines of the race.

toyota

In addition to the credentials of hydrogen’s greenness, there are other problems.

On the Formula One Grand Prix and other events test run at the Suzuka circuit in March, a Toyota vehicle powered by liquid hydrogen caught fire.

A leak sensor that was correctly functioning stopped the hydrogen leak in less than a tenth of a second from a pipe that had become loose due to the vehicle’s vibrations. According to Toyota, nobody was harmed, the cabin was secured, and the fire was put out.

Toyota’s No. 32 Corolla, one of the dozens of vehicles competing in the 24-hour race at Fuji Speedway, was doomed to fall short. Refueling and pit checks—important to racing—took several minutes in a race where competitors are battling for seconds.

However, according to Tomoya Takahashi, president of Toyota’s Gazoo Racing Co., introducing liquid hydrogen into racing may be a modest step in the right direction.

“We’re constructing for the future in this. He argued that the internal combustion engine has potential and is not the only solution.

2023: Decorated Australian War Veteran Unlawfully Killed Prisoners In Afghanistan

Published

on

australian

Melbourne — Australian Ben Roberts-Smith, the recipient of the Victoria Cross, claimed that the media falsely accused him, but a judge concluded on Thursday that he unlawfully killed captives and committed other war crimes in Afghanistan.

Roberts-Smith, a former Special Air Service Regiment corporal who is currently a media firm executive, is accused of committing a series of war crimes, according to publications published in 2018. Federal Court Justice Anthony Besanko determined that these articles were essentially factual.

Besanko concluded that Roberts-Smith, who received the Medal of Gallantry for his contributions during the Afghanistan War, had “broken the moral and legal rules of military engagement” and had dishonored Australia with his actions.

The decision, which came after a contentious trial that lasted 110 court hearing days and is estimated to have cost more than 25 million Australian dollars ($16 million) in legal bills, is viewed as a landmark victory for press freedom against Australia’s draconian defamation rules.

A machine gun was allegedly used by Roberts-Smith, a judge’s son, to shoot a detainee wearing a prosthetic leg in the rear in 2009 in a Taliban base in the province of Uruzgan known as Whisky 108. He retained the man’s prosthetic to use as a fun beer mug.

The man was one of two unarmed Afghans taken from a tunnel by Roberts-Smith’s patrol. To “blood the rookie,” Roberts-Smith forced a “newly deployed and inexperienced” soldier to murder the second, more seasoned warrior.

The decision came after a contentious trial that lasted 110 court hearing days and is estimated to have cost more than 25 million Australian dollars ($16 million) in legal bills.

In addition, it was established that in the Afghan hamlet of Darwan in 2012, Roberts-Smith kicked an unarmed, handcuffed farmer named Ali Jan off a cliff and into a riverbed before killing him. Then Roberts-Smith ordered one of his soldiers to shoot Jan to death.

Allegations that Roberts-Smith, who is 2.02 meters (6 feet, 7 inches) tall, intimidated soldiers and abused Afghan villagers were also proven genuine.

The judge determined that two of the six unlawful killings Roberts-Smith was alleged to have participated in were not proven by the civil court standard of the balance of probabilities.

Additionally, it was determined that the allegations of domestic violence against Roberts-Smith were false and defamatory. The judge concluded that the unfounded charges would not further harm the veteran’s reputation.

Such claims of war crimes would have required proof beyond a reasonable doubt if they had been made in a criminal court.

The 44-year-old Roberts-Smith has denied any misconduct. His attorneys attributed his termination to “corrosive jealousy” on the part of “bitter people” within the SAS who had waged a “poisonous campaign against him.”

Because of their stories, the Sydney Morning Herald, The Age, and The Canberra Times were accused of defaming each other in the civil lawsuit.

One of the journalists, Nick McKenzie, who wrote the divisive articles, commended the SAS veterans who had testified against the national hero.

The day of justice is today. It’s a day of justice for those courageous SAS members who came out and exposed Ben Roberts-Smith for the war criminal, bully, and liar that he is, McKenzie told reporters outside court.

The Australian Federal Police is investigating Roberts-Smith and other Australian military members for possible war crimes in Afghanistan.

“Those SAS members are a proud representation of Australia. The bulk of the SAS stood up for what was right, and their actions were rewarded, said McKenzie.

Arthur Moses, the attorney for Roberts-Smith, requested an additional 42 days to contemplate filing an appeal with the Federal Court’s Full Bench.

Billionaire Kerry Stokes, executive chair of Seven West Media, where Roberts-Smith works, has agreed to pay the case’s legal expenses.

Stokes’s statement in support of Roberts-Smith was, “The judgment does not accord with the man I know.”

Ben has always maintained his innocence, so I know this will be difficult for him, Stokes said.

Roberts-Smith had been there each day of his trial but did not show up in Sydney for the verdict. On Wednesday, media outlets published a picture of him relaxing by a pool in Bali, an Indonesian tourist destination.

The first criminal accusation about an alleged illegal killing in Afghanistan was brought in March. Oliver Schulz, a former SAS trooper, was accused of committing a war crime by killing an Afghan in a wheat field in Uruzgan province in 2012.

The decision was a “very disappointing day” for the elite unit, according to Martin Hamilton-Smith, chair of the Australian Special Air Service Association. He said that charges against more veterans should be brought immediately if they were tried for war crimes.

According to Hamilton-Smith, the only way to learn the real truth about this is to bring it before a criminal court, where both sides of the story may be presented, and the facts can be proven beyond a reasonable doubt.

When Roberts-Smith received the Victoria Cross in 2011, Australia’s highest honor for valor in the face of an enemy, he was elevated to a national hero. As a famous Australian, he had multiple meetings with Queen Elizabeth II.

He received the medal 2010 for taking out a machine gun nest at Tizak, Kandahar, during combat. Two machine gunners and an enemy preparing to throw a rocket grenade were killed thanks to Roberts-Smith. No allegations of war crimes related to that conflict.
