Antarctica

In a recent research in Antarctica, scientists found out that the crack in Antarctica ice shelf has grown by 17 kilometres and soon going to be a treat for human life.

According to the British scientists, a mammoth crack in one of Antarctica’s largest ice shelves grew vividly over the past few months, and a gigantic mass more than twice the size of ice shelf could break away very soon next summer. This can be an enormous threat to the human life.

If this cracks continuous to grow, it can accelerate to break up a further mass of the ice shelf. It is effectively removing towards a massive cork of ice that prevents some of Antarctica’s glaciers from flowing into the ocean.

Scientists are suspecting that this crack followed by melt down of the ice shelf can raise the water level by 10 centimetres. They are striving to find some way to prevent this crack from falling off. However, this sudden crack is the latest sign of major ice loss in the fast warming Antarctic Peninsula. History has already shown the sudden breakup of two other massive shelves in the same region. Main cause of such event is widely endorsed to climate change.

This sudden crack in the ice shelf is known as Larsen C. Initially, it cracked for 17 kilometers till December. But it is eventually reaching towards 21 kilometres dangerously. If this crack continues, scientists say it will be impossible to handle the consequences.

The researchers, in their final statement said, “When it calves, the Larsen C Ice Shelf in Antarctica will lose more than 10 per cent of its region. It will leave the ice front at its most retreated position ever recorded; this event will primarily change the landscape of the Antarctic Peninsula,”

The rift has grown over 80 kilometres since 2011. It is almost 160 kilometres long in entire length. It has widened to well over 300 metres. Now, only 19 kilometres of ice is connected to the chunk with the rest of the ice shelf in Antarctica.

The researchers also noted the point to the public that fortunately the Antarctic Peninsula does not contain nearly as much ice as other peninsula. The thicker parts of Antarctica are the West and East Antarctic ice sheets. And the peninsula is not much thicker compared to that. If Larsen C ice shelf falls off to water, the potential rise will be measured in centimetre and not in feet.
