Images of harp seals taken from hundreds of miles above show their plight. They should spur us to action

This week, remarkable images were released of harp seals scattered across a fragmented and rapidly disintegrating ice sheet east of Greenland. With record high temperatures and early melting in the Arctic, great cracks create a deadly mosaic on the sheet, an icy crazy paving on which you can make out dark specks - each one a seal, peering out as if bemused by its fate. In such an inhospitable environment, viewed from such height, the marine mammals resemble alien life forms glimpsed on another planet.

By 2035, it is estimated that the disappearance of Arctic sea ice will mean that around 7.5 million harp seals will lose their home. It is another cruel turn for animals that in the 20th century were extensively hunted for their fur - especially the flawless white pelts of their pups. They depend on the sea ice: it is the arena in which they rest after hunting for food, mate, and give birth. The ice is the centre of their lives.
