Arctic sea ice hits lowest peak in satellite record, says US agency

  • Arctic sea ice forms and expands during the dark, frigid northern winter, reaching its seasonal high point in March
  • In recent years, less new ice has formed, and the accumulation of multi-year ice has steadily declined

WASHINGTON: This year’s Arctic Sea ice peak is the lowest in the 47-year satellite record, according to data released by the US National Snow and Ice Data Center (NSIDC) on Thursday, as the planet continues to swelter under the mounting effects of human-driven climate change.
Arctic sea ice forms and expands during the dark, frigid northern winter, reaching its seasonal high point in March. But in recent years, less new ice has formed, and the accumulation of multi-year ice has steadily declined.
The maximum sea ice level for 2025 was likely reached on March 22, measuring 14.33 million square kilometers (5.53 million square miles) — below the previous low of 14.41 million square kilometers set in 2017.
“This new record low is yet another indicator of how Arctic sea ice has fundamentally changed from earlier decades,” said NSIDC senior research scientist Walt Meier in a statement.
“But even more importantly than the record low is that this year adds yet another data point to the continuing long-term loss of Arctic sea ice in all seasons.”
The Arctic record follows a near-record-low summer minimum in the Antarctic, where seasons are reversed.
The 2025 Antarctic sea ice minimum, reached on March 1, was just 1.98 million square kilometers, tying for the second-lowest annual minimum in the satellite record, alongside 2022 and 2024.
Combined Arctic and Antarctic sea ice cover — frozen ocean water that floats on the surface — plunged to a record low in mid-February, more than a million square miles below the pre-2010 average. That is an area larger than the entire country of Algeria.
“We’re going to come into this next summer season with less ice to begin with,” said Linette Boisvert, an ice scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It doesn’t bode well for the future.”
US scientists primarily monitor sea ice using satellites from the Defense Meteorological Satellite Program (DMSP), which detect Earth’s microwave radiation.
Because open water and sea ice emit microwave energy differently, the contrast allows sea ice to stand out clearly in satellite imagery — even through cloud cover, which obscures traditional optical sensors.
DMSP data is supplemented with historical records, including early observations from the Nimbus-7 satellite, which operated from 1978 to 1985.
While floating sea ice does not directly raise sea levels, its disappearance sets off a cascade of climate consequences, altering weather patterns, disrupting ocean currents, and threatening ecosystems and human communities.
As reflective ice gives way to the darker ocean, more solar energy is absorbed rather than reflected back into space, accelerating both ice melt and global warming.
Shrinking Arctic ice is also reshaping geopolitics, opening new shipping lanes and drawing geopolitical interest. Since taking office this year, US President Donald Trump has said his country must control Greenland, a Danish autonomous territory rich in mineral resources.
The loss of polar ice spells disaster for numerous species, robbing polar bears, seals, and penguins of crucial habitat used for shelter, hunting, and breeding.
Last year was the hottest on record, and the trend continues: 2025 began with the warmest January ever recorded, followed by the third-warmest February.
NOAA predicts that La Nina weather conditions, which tend to cool global temperatures, are likely to give way to neutral conditions that would persist over the Northern Hemisphere summer.
Polar regions are especially vulnerable to global warming, heating several times faster than the global average.
Since mid-2023, only July 2024 fell below 1.5 degrees Celsius of warming, raising concerns that the Paris Agreement’s goal of limiting long-term warming to 1.5C may be slipping out of reach.


SpaceX says debris recovery attempts hindered after Starship explosion

SpaceX says debris recovery attempts hindered after Starship explosion

  • The Starship rocket appeared to have experienced at least two explosions in rapid succession

SpaceX said on Thursday its debris recovery efforts after last week’s Starship explosion have been hindered and it has sought cooperation from Mexico, whose president has raised the possibility of legal action against the company.
A massive Starship spacecraft by SpaceX exploded into a dramatic fireball during testing in Texas last week, which Elon Musk’s space firm attributed to a “major anomaly.”
The Starship rocket appeared to have experienced at least two explosions in rapid succession, lighting up the night sky and sending debris flying, according to video capturing the moment it exploded.
“Despite SpaceX’s attempts to recover the anomaly related debris, which is and remains the tangible property of SpaceX, these attempts have been hindered by unauthorized parties trespassing on private property,” the company said in a post on social media platform X.
“We have requested local and federal assistance from the government of Mexico in the recovery,” it said, adding that it also has offered resources and assistance in the clean-up.
President Claudia Sheinbaum said on Wednesday that her administration is investigating the security and environmental impact of the launch of rockets, particularly for the Mexican state of Tamaulipas.
A general review is being conducted to determine what international laws are being violated. “From there, we’ll start a process, because there is indeed contamination,” Sheinbaum had said during a morning press conference.
A Starship spacecraft exploded in space minutes after lifting off from Texas in March, prompting the FAA to halt air traffic in parts of Florida, in a setback for Musk’s Mars rocket program.
In January, a Starship rocket broke up in space minutes after launching from Texas, raining debris over Caribbean islands and causing minor damage to a car in the Turks and Caicos Islands.

Sean ‘Diddy’ Combs used ‘power, violence and fear’: prosecutor

NEW YORK:  Sean “Diddy” Combs used “power, violence, and fear” as the head of a decades-old criminal enterprise, a prosecutor said Thursday in closing arguments in his high-profile trial.
“He counted on silence and shame to keep his crimes hidden,” Christy Slavik told the jury as the government began wrapping up its case against the once-powerful music mogul.
The 55-year-old Combs was seated behind the prosecutor as she delivered her closing arguments, passing an occasional message to his lawyers.
Slavik methodically walked the jury through the charges against Combs, which include racketeering and sex trafficking.
“He used power, violence and fear to get what he wanted,” she said, and relied on a network of “loyal lieutenants” — none of whom testified at his trial — to cover up his crimes, which included forced labor, bribery and witness tampering.
“He became more powerful and more dangerous because of the support of his inner circle and his businesses,” she said. “This is Mr.Combs’s kingdom.”
Slavik told the jury the case was not about criminalizing unorthodox sex.
“It’s not about free choices at all,” she said.
The women involved were “drugged, covered in oil, sore, exhausted” as Combs made them have sex with escorts for hours, she said.
The famed producer coerced two women — the singer Casandra Ventura and later a woman who testified under the pseudonym Jane — into years of drug-addled sex with paid escorts, prosecutors say.
The most serious charge, racketeering — which includes the existence of a criminal enterprise that committed a pattern of offenses — could send Combs to prison for life.
He faces two charges of sex trafficking and two more for transportation for purposes of prostitution.
Combs denies it all. His lawyers have argued that the artist’s relationships were consensual and have sought to convince jurors that many of the witnesses who testified were doing so for financial gain or jealousy.
Along with alleged victims, government witnesses included former assistants and other employees, as well as escorts, friends and family of Ventura, and a hotel security guard who said he was bribed with $100,000 in a paper bag.
Combs opted against testifying on his own behalf, a common strategy of defense teams who are not required to prove innocence, only to cast doubt on government allegations of guilt.
The government’s evidence included thousands of pages of phone and text records, and hours of testimony involved meticulous readings of some of the most explicit and wrenching exchanges.
Many of those records appear to indicate distress on the part of the alleged victims. But a lot of the messages also show affection and desire — texts the defense underscored again and again.
Jurors have seen video evidence of the sex parties prosecutors say were criminal, while the defense has exhibited exchanges they say imply consent.
Also in evidence are reams of financial records — including CashApp payments to escorts — as well as flight and hotel records.
Since early May the proceedings have gripped the Manhattan federal courthouse where they’re taking place.
And though electronics are barred from the building, dozens of influencers and content creators have buzzed around the courthouse’s exterior every day, delivering hot takes to eager social media fans.
Combs is incarcerated and does not enter or exit the courthouse publicly. But some of the high-profile attendees and witnesses do, including members of the music mogul’s family and figures like Kid Cudi, the rapper who testified that Combs’s entourage torched his car.
The closing arguments by the prosecution are expected to wrap up on Thursday and the defense is likely to start its closing on Friday.
The jury of 12 New Yorkers could get the case as early as Friday afternoon.

Microsoft and OpenAI dueling over artificial general intelligence, The Information reports

  • The report comes at a time when one of the most pivotal partnerships in the field of AI is under strain

Microsoft and OpenAI are at odds over a contractual provision related to artificial general intelligence, The Information reported on Wednesday.
Under the current terms, when OpenAI achieves AGI, Microsoft’s access to such a technology would be void. Microsoft wants OpenAI to remove that clause but so far OpenAI has refused, the report said.
“We have a long-term, productive partnership that has delivered amazing AI tools for everyone. Talks are ongoing and we are optimistic we will continue to build together for years to come,” OpenAI and Microsoft said in a joint statement emailed to Reuters.
The report comes at a time when one of the most pivotal partnerships in the field of AI is under strain.
OpenAI needs Microsoft’s approval to complete its transition into a public-benefit corporation. But the two have not been able to agree on details even after months of negotiations, according to sources.
Microsoft partnered with OpenAI in 2019, investing $1 billion to support the startup’s development of AI technologies on its Azure cloud platform.

 


An Alaskan brown bear has a new shiny smile after getting a huge metal crown for a canine tooth

An Alaskan brown bear has a new shiny smile after getting a huge metal crown for a canine tooth

  • The 360-kilogram Tundra was put under sedation Monday and fitted with a new crown
  • “He’s got a little glint in his smile now,” zoo marketing manager Caroline Routley said

MINNESOTA: An Alaskan brown bear at the Lake Superior Zoo in northeastern Minnesota has a gleaming new silver-colored canine tooth in a first-of-its-kind procedure for a bear.

The 800-pound (360-kilogram) Tundra was put under sedation Monday and fitted with a new crown — the largest dental crown ever created, according to the zoo.

“He’s got a little glint in his smile now,” zoo marketing manager Caroline Routley said Wednesday.

The hour-long procedure was done by Dr. Grace Brown, a board-certified veterinary dentist who helped perform a root canal on the same tooth two years ago. When Tundra reinjured the tooth, the decision was made to give him a new, stronger crown.

The titanium alloy crown, made by Creature Crowns of Post Falls, Idaho, was created for Tundra from a wax caste of the tooth.

Brown plans to publish a paper on the procedure in the Journal of Veterinary Dentistry later this year.

“This is the largest crown ever created in the world,” she said. “It has to be published.”

Tundra and his sibling, Banks, have been at the Duluth zoo since they were 3 months old, after their mother was killed.

Tundra is now 6 years old and, at his full height on his hind legs, stands about 8 feet (2.4 meters) tall. The sheer size of the bear required a member of the zoo’s trained armed response team to be present in the room — a gun within arm’s reach — in case the animal awoke during the procedure, Routley said. But the procedure went without a hitch, and Tundra is now back in his habitat, behaving and eating normally.

Other veterinary teams have not always been as lucky. In 2009, a zoo veterinarian at Henry Doorly Zoo and Aquarium in Omaha, Nebraska, suffered severe injuries to his arm while performing a routine medical exam on a 200-pound (90 kilogram) Malaysian tiger.

The tiger was coming out of sedation when the vet inadvertently brushed its whiskers, causing the tiger to reflexively bite down on the vet’s forearm.

Bears get paws on the honey in UK wildlife park escape

  • The pair made a beeline for their food store where they scoffed snack’s including the seven-day supply of honey
  • During the hour-long drama, the bears were “continuously monitored both on the ground and via CCTV“

LONDON: Two young bears escaped from their enclosure at a UK wildlife park and devoured a week’s worth of food store honey before falling asleep, the attraction said on Tuesday.

Mish and Lucy, both aged four, got out of their enclosure at Wildwood Devon in southwestern England on Monday afternoon.

The pair made a beeline for their food store where they scoffed snack’s including the seven-day supply of honey, a park statement said.


The bears “posed no threat to the public at any point” although visitors on site were escorted to a secure building as a precaution.

During the hour-long drama, the bears were “continuously monitored both on the ground and via CCTV” until they were returned to their enclosure by keepers and promptly “fell asleep,” Wildwood added.

Police attended the scene and an investigation was underway to determine how the animals managed to break out, it said.

The park spread across 40 acres (160 hectares) of gardens and woodland is home to an array of wildlife including brown bears, wolves and arctic foxes.
