A crack in the ice shelf!

Due to warming temperatures a crack in Antarctica’s fourth-largest ice shelf is about to break up. As a result of this the break will create one of the largest icebergs ever recorded. An ice shelf is created when runoff from glaciers float in water and provide support to the glaciers. When they collapse the glaciers behind them can accelerate towards the ocean.

This ice shelf called Larsen C would not add much water to the global sea level. But the problem is that with collapsing ice shelves glaciers will flow more quickly towards the ocean and that could cause higher levels of ocean rise.

As the climate becomes warmer it is a safe bet that other ice shelves in Antarctica will be more vulnerable to collapse, with the result that more water would be added to the oceans, with unpredictable results. Coastal settlements would surely be affected in the long run.
