World’s largest iceberg stuck near Antarctic island after 40-year journey
London: Iceberg A23a, the world’s biggest iceberg, has become stuck 73 km from a remote Antarctic island after drifting towards South Georgia since 2020. Measuring approximately 3,300 sq km and weighing nearly 1tn tonnes, its grounding has raised concerns about its potential impact on local wildlife, including penguins and seals.
According to The Guardian, which cited a research organisation, there were initial fears that the iceberg could collide with the island or run aground in shallow waters, making it difficult for animals to feed their young. However, British Antarctic Survey (BAS) oceanographer Andrew Meijers stated that if the iceberg remains in its current position, it is unlikely to ‘significantly affect the local wildlife.’
A23a, which calved from the Antarctic ice shelf in 1986, had remained stuck for decades before breaking free in 2020. Since late 2023, researchers have been tracking its movement via satellite. While a 19 km-long chunk broke off in January, the iceberg has not shown significant signs of disintegration along its current path.
Meijers noted that icebergs following this route through the Southern Ocean typically break up, disperse, and melt. However, concerns remain about the impact on South Georgia’s wildlife, as animals may be forced to travel further to reach feeding grounds, potentially increasing mortality among penguin chicks and seal pups.
Meanwhile, researchers have warned that a rise in global temperatures to between 1.5 and 2 degrees Celsius above preindustrial levels could accelerate the melting of frozen water, leading to significant ocean level increases.

PM Modi to flag off Meerut Metro, Namo Bharat train on Feb 22
New Delhi (PTI): Prime Minister Narendra Modi on Sunday will visit Meerut and flag off the Meerut Metro and Namo Bharat train at Shatabdi Nagar Namo Bharat station in the western Uttar Pradesh town.
From there, the prime minister will undertake a metro ride till Meerut South station and at around 1 pm, he will inaugurate and dedicate to the nation various development projects worth around Rs 12,930 crore in Meerut.
Modi will also address the gathering on the occasion, said a statement issued by the Prime Minister's Office.
The prime minister will dedicate to the nation the entire 82 Km Delhi–Meerut Namo Bharat corridor. He will inaugurate the remaining sections of India's first Namo Bharat Regional Rapid Transit System (RRTS), which include the 5 km section between Sarai Kale Khan and New Ashok Nagar in Delhi and the 21 km section between Meerut South and Modipuram in Uttar Pradesh.

With a design speed of 180 km per hour, Namo Bharat is India's first regional rapid transit system. It will connect major urban centres such as Sahibabad, Ghaziabad, Modinagar and Meerut with Delhi at a faster pace, the statement said.
The Sarai Kale Khan, the originating station of the corridor, is one of the four Namo Bharat stations to be commissioned with this inauguration.
It is strategically located as a major multi-modal hub, seamlessly connecting Hazrat Nizamuddin railway station, Delhi Metro's pink line, Veer Haqeeqat Rai ISBT, and the ring road. The other three Namo Bharat stations, Shatabdi Nagar, Begumpul and Modipuram, being commissioned are in Meerut.
The prime minister will also inaugurate the Meerut Metro services between Meerut South and Modipuram, operating on the same infrastructure as Namo Bharat, in a first-of-its-kind initiative in the country.
The Meerut Metro will be India's fastest metro system with a maximum operational speed of around 120 kmph. The metro will cover the entire stretch in just 30 minutes, with all scheduled stoppages en route.
This seamless integration of Namo Bharat and Meerut Metro on the same infrastructure will ensure high-speed intercity travel and swift intra-city movement, setting a benchmark for integrated urban and regional transit in India. It will decongest road traffic and consequently lead to a significant reduction in vehicular carbon dioxide emissions.
These projects will provide further impetus to the prime minister's vision of transforming urban mobility and ensuring seamless, efficient, modern and sustainable public transport systems that improve ease of living for citizens, the statement said.
