A worrying warning about ice sheets is five times bigger than London

The new activity of a trillion-ton ice sheet is worrying scientists.

A one-trillion-ton ice sheet has five times the area of ​​London spinning on the ocean after it is separated from an Antarctic ice shelf, The Sun reported.

A-68 ice is five times larger than London.

The large ice sheet, known as A-68 , broke off the Antarctic Larsen C ice shelf last year.

Previous scientists thought the ice sheet would get stuck in the seabed and not drift away.

But the new data has shown that in the past few months, the ice sheet has begun to spin.

With a thickness of about 335m, scientists fear the ice sheet will have a huge impact on sea level.

Polar oceanographer Mark Brandon said in July that "weather conditions and ocean currents could cause the trillion tons of ice A68 to rotate in an anti-clockwise direction."

Writing on his blog, he said July 20 temperatures were nearly 20 degrees warmer than normal temperatures.

Professor Brandon predicts the iceberg will continue to spin.

'I guess A68 will continue to spin . until its edge touches Larsen C's front , ' Brandon said.

'It has great momentum and will not stop easily. I think we'll see some interesting bumps on the ice shelf in the next few months. '

Scientists fear the ice shelf may continue to collapse and affect the planet's climate balance.

Ice shelves float on the sea, acting as a giant braking system, preventing the river from flowing directly into the ocean.

If the ice blocks fell to Antarctica, they could raise global sea levels by about 10cm, the researchers said.

Ice shelves are known to collapse naturally, but global warming is said to accelerate this process.
