Monster iceberg ‘A23a’ just shy of a trillion tonnes
Scientists now have good numbers to describe the true scale of the world’s biggest iceberg, A23a.
Satellite measurements show the frozen block has a total average thickness of just over 280m (920ft).
Combined with its known area of 3,900 sq km (1,500 sq miles), this gives a volume of roughly 1,100 cubic km and a mass just below a trillion tonnes.
The iceberg, which calved from the Antarctic coast in 1986, is about to drift beyond the White Continent. It has reached a critical point in its journey, researchers say, with the next few weeks likely to decide its future trajectory through the Southern Ocean.

To put the new thickness data in some context, London skyscraper 22 Bishopsgate is 278m tall – bettered, in the UK, by only the 310m Shard tower.
But A23a is also more than twice the area of Greater London, giving it an overall profile much like that of a credit card.

The measurements of A23a come from the European Space Agency’s CryoSat-2 mission. This veteran spacecraft carries a radar altimeter able to sense how much of a berg’s bulk is above the waterline.
Using information about the density of ice, it is then possible to determine how much must be submerged.
“Altimetry satellites like CryoSat-2, which measure the distance to the iceberg surface and to the sea surface, allow us to monitor iceberg thickness from space,” Dr Anne Braakmann-Folgmann, from the University of Tromsø – The Arctic University of Norway, told BBC News.
“They also enable us to watch the iceberg thinning as it gets exposed to warmer ocean waters. “And together with knowledge of the sea-floor topography, we know where an iceberg will ground or when it has thinned enough to be released again.”

When the berg started moving, after 2020, it became increasingly difficult to obtain broad thickness measurements. But assuming an area of 3,900 sq km and an average total thickness of 285m, then A23a has a volume of 1,113 cubic km and a mass of 950 billion tonnes.

Born in a mass breakout of bergs from the Filchner Ice Shelf, in the southern Weddell Sea, A23a was almost immediately stuck in shallow bottom muds to become an “ice island” for more than three decades. And the CryoSat data can now explain why.
The berg is not a uniform block – some parts are thicker than others.
CryoSat indicates one section in particular has a very deep keel, which in 2018, had a draft – the submerged portion of an iceberg – of almost 350m and it is this section that anchored A23a for so long.
Satellite images show crevasses directly above the keel.
“This is likely the surface expression of the damage that was caused when A23a hit the seabed,” Prof Andrew Shepherd, from Northumbria University and the Natural Environment Research Council Centre for Polar Observation and Modelling (CPOM), said.

And in the years that followed, A23a gradually lost mass to eventually free itself and start moving.
“Over the last decade, we have seen a steady 2.5m per year decrease in thickness, which is what you would expect given the water temperatures in the Weddell Sea,” Dr Andy Ridout, a CPOM senior research fellow from University College London, explained.
A23a has now reached the tip of the Antarctic Peninsula, where there is a convergence of various streams of fast-moving water that turn clockwise around the continent.
How it interacts with these and the westerly winds that dominate in that part of the world will control where the behemoth goes next.
But it is expected take a track called “iceberg alley” that points in the direction of the British overseas territory of South Georgia.

Scientists will follow its progress with interest.
Bergs this big have a profound influence on their environment. “They’re responsible for very deep mixing of seawater,” Prof Mike Meredith, from the British Antarctic Survey, told BBC News. “They churn ocean waters, bringing nutrients up to the surface, and, of course, they also drop a lot of dust.
“All this will fertilise the ocean – you’ll often see phytoplankton blooms in their wake.”

Heavy rains and flooding kills at least 23 in Nairobi
At least 23 people have been killed in Nairobi after heavy rain overnight caused severe flooding in Kenya’s capital city.
Police said about 30 people had been rescued but many others drowned after being swept into rivers – some have been electrocuted.
Kenya’s military has been deployed to help people trapped inside their cars as police described widespread damage to properties as well as road closures.
Several flights bound for Nairobi Airport had to be cancelled or diverted to the coastal city of Mombasa.
“The torrential rains have led to significant flooding, unfortunately resulting in 23 fatalities so far, the destruction of property, road closures, and the displacement of residents,” police said in a statement on Saturday afternoon.

Qatar partially reopens airspace as Iranian strikes continue to hit Gulf
Qatar has partially reopened its airspace days after Iranian missile and drone strikes forced the country to ground all flights as a United States-Israeli military campaign against Iran continues into its seventh day.
The Qatar Civil Aviation Authority announced the limited opening on Friday evening, saying flights would operate through “designated navigational contingency routes with limited operational capacity” in coordination with the Qatari armed forces.
The move marks a cautious first step towards restoring air links to one of the Gulf’s most important aviation hubs but falls well short of a return to normality, with scheduled commercial flights to and from Doha remaining suspended until a further official announcement is made.
The Qatar Civil Aviation Authority said the partial reopening covers only a narrow category of flights “designated for passenger evacuation” and air cargo services.
Passengers with confirmed bookings were urged to follow updates from their airlines directly before travelling to the airport.
Early on Saturday, Qatar Airways said it “intends to operate repatriation flights on 07 March, departing Hamad International Airport to the following airports: London (LHR), Paris (CDG), Madrid (MAD), Rome (FCO), Frankfurt (FRA)”.
It added that priority would be given to “stranded passengers with families, elderly passengers, and those with urgent medical and compassionate travel needs”.
The Gulf country has been repeatedly struck by Iranian missiles and drones throughout the now seven-day conflict, forcing the country to activate its air force and use interceptors to defend its territory. Qatar’s Ministry of Defence confirmed the country had been struck by 14 ballistic missiles and four drones fired from Iran on Thursday.
More than 2,000 flights have been cancelled at Doha’s Hamad international airport since the conflict began.
Aviation across the Gulf
Across the Gulf, airports and airlines have been scrambling to manage the fallout from nearly a week of Iranian missile and drone barrages, launched in retaliation for the ongoing US-Israeli military campaign – codenamed Operation Epic Fury – which has killed at least 1,332 people in Iran since strikes began last Saturday, according to Iranian officials.
Emirates airline announced it is operating a reduced schedule while working to restore full network operations, carrying approximately 30,000 passengers out of Dubai on Friday alone.
By Saturday, the airline said it would have 106 daily return flights operating to 83 destinations, close to 60 percent of its full network, with a return to 100 percent expected “within the coming days, subject to airspace availability”.
Dubai international airport, the world’s busiest airport for international passengers, was evacuated on Sunday following Iranian strikes and has recorded close to 4,000 flight cancellations since Monday.
Abu Dhabi’s Zayed international airport has seen more than 1,000 cancellations and continues to operate at limited capacity.
Kuwait, also impacted by Iranian strikes, saw its airport undergo sustained physical damage in drone strikes, leaving some workers with minor injuries, and its airspace remains fully closed to commercial traffic.
Kuwait Airways has begun rerouting citizens with prior bookings through Jeddah, Saudi Arabia.
An estimated 23,000 flights have been cancelled since late February, according to analytics firm Cirium.

Human rights court orders reparations for forced sterilization case in Peru
The Inter-American Court of Human Rights (IACHR) has ordered Peru to pay reparations to the family of Celia Ramos, a mother of three whose death resulted from a campaign of forced sterilizations during the 1990s.
Thursday’s landmark ruling stated that the 34-year-old Ramos was coerced into sterilization against her will, causing an allergic reaction that led to her death.
The court ordered Peru to pay her family $340,000 as part of the ruling.
It noted that the Peruvian government had “failed to fulfill its obligation to initiate and conduct a thorough investigation” into Ramos’s case, heightening the strain on her family.
“Ms Ramos Durand’s family members — especially her three daughters, who were children at the time of the events — suffered profound harm as a consequence of the sterilization and death of Celia Edith Ramos Durand and the impunity surrounding the case,” the IACHR wrote in its decision.
Peru’s campaign of forced sterilization took place under the late President Alberto Fujimori, whose tenure included widespread human rights abuses that continue to cast a shadow over the country.
The scheme largely targeted poor and Indigenous women who were often tricked or coerced into sterilisation procedures.
This week’s ruling is the first time the human rights court has weighed in on the issue, which has been the subject of years of legal contestation in Peru.
“After almost 30 years of searching for justice, the Inter-American Court of Human Rights recognised the responsibility of the Peruvian state in the forced sterilization and death of Celia Ramos,” the Peruvian feminist organisation DEMUS said in a social media post, celebrating the ruling.
“This ruling marks a fundamental step in reparations for Celia, her family and the thousands of victims of forced sterilizations in Peru.”
As many as 314,000 women and 24,000 men were sterilized against their will in Peru under Fujimori’s government, which sought to forcibly lower the birth rate as a means of addressing poverty.
The procedures were particularly invasive for the women involved, and some suffered long-term complications, including death.
Family members often received little information about the circumstances that led to loved ones dying after the unnecessary operations. Some survivors did not realise what had happened to them until years later, when they discovered they were unable to have children.
In Ramos’s case, the 34-year-old mother had gone to a state health clinic for medical assistance on July 3, 1997, but was instead forced to undergo tubal ligation.
Ramos, however, suffered a severe allergic reaction during the procedure. She was placed in a recovery room, but the clinic was not able to treat her adequately.
In its decision, the IACHR explained that the clinic “lacked the necessary equipment and medications for adequate risk assessment or to handle emergencies”.
Ramos was ultimately transferred to an intensive care unit in the city of Piura, where she died 19 days later, on July 22, 1997.
The state did not carry out an autopsy and declined to share details with her family.
The compensation outlined in this week’s ruling includes reimbursement for the costs of medical procedures conducted to save Ramos’s life and the estimated loss of income from her death.
In October 2024, the Committee on the Elimination of Discrimination against Women at the United Nations ruled that Peru’s sterilization programme amounted to sex-based violence and discrimination against poor, rural and Indigenous women.
The committee’s statement cited a lack of adequate medical facilities and a lack of informed consent, just as the IACHR did in its decision this week.
“The victims described a consistent pattern of being coerced, pressured, or deceived into undergoing sterilizations at clinics lacking proper infrastructure or trained personnel,” committee member Leticia Bonifaz said.
“The procedures were carried out without informed consent from these victims, with some of them, especially those from remote areas, unable to read and speak Spanish, or fully understand the nature of the procedure.”
Scholars have concluded that Fujimori’s sterilization campaign was driven, in part, by racist views among government officials who saw rural, Indigenous communities as an obstacle to economic modernisation.
