World's biggest iceberg on collision course with penguin island

An enormous iceberg is heading towards South Georgia Island in the southern Atlantic, where scientists say a collision could devastate wildlife by threatening the food chain.
Scientists have long been watching this climate-related event unfold, as the iceberg - the size and shape of Jamaica – has meandered and advanced over two years since breaking off from the Antarctic peninsula in July 2017.

Iceberg A68a is 4,200 sq km in size and is about the same shape and size as Jamaica.
The peninsula is one of the fastest-warming places on Earth, registering a record high temperature of 20.75 degrees Celsius on February 9. The warming has scientists concerned about ice melt and collapse leading to higher sea levels worldwide. ....

South Georgia Island: Giant iceberg 'days away' from island impact, killing millions of wildlife

A68A, the monstrous 4200-square-kilometre iceberg is the size of South Georgia itself.
The impact would crush marine life on the sea floor, such as coral, sponges and plankton.

It also has the potential to block the island s 2 million penguins as well as seals from their hunting areas, Norman Ratcliffe, a seabird biologist in the Ecosystems Division of the British Antarctic Survey who have been monitoring the iceberg, said.
Whether the collision is days or weeks away is unclear, according to Geraint Tarling, a biological oceanographer who has been tracking the iceberg with the British Antarctic Survey. ....

Iceberg A68a, photographed by European Space Agency satellite Sentinel-3 on December 9, approaches South Georgia in the South Atlantic.
On South Georgia, a remote island in the South Atlantic, millions of penguins in some of the largest colonies on the planet live out their days amid a pristine environment shared with only a handful of humans. An ex-whaling outpost, today it sits in over one million square kilometers of marine protected area, allowing species to thrive despite its rugged, sometimes hostile climate. ....

A68a the world's biggest iceberg heads for disaster

A68a the world’s biggest iceberg heads for disaster
Manhattan Island,
World’s biggest iceberg heads for disaster
The mass is now moving straight toward a remote south Atlantic island populated by penguins and seals. Scientists say a collision could cause a local, environmental catastrophe.
By
Iceberg A68a has been on a slow journey toward cataclysm.
The mass broke from the Antarctic peninsula’s Larsen C ice shelf in July 2017 and headed slowly for the open ocean, sliding through the water for over two years until it hit the powerful Antarctic Circumpolar Current circling the southernmost continent.
And then, like a speed skater, it was on its way. The current propelled the berg on a fast track through what scientists call “iceberg alley,” a northeast route traveled by chunks of ice that break from the peninsula. ....
