What will happen when the ice sheets of Antarctica melt entirely? Without any doubt we can say, it ends with the total destruction of the entire nature. Finally, a study found in 2016 that adding a couple of new processes to the model of the Antarctic ice sheets made them much more vulnerable to melt.

If this happens, it will also cause a remarkable increase in sea level globally. Actually, scientists just randomly conducted this experiment. The scientists left the assessment and solution of this problem as a question mark.

Hydrofracturing and collapsing of ice cliffs above a certain height were the new processes. A fracture in the surface of the ice sheet visible through to the bottom called the latter. Probably, hydrofracturing also plays a vital role in the process of the sudden collapse of Antarctica’s Larsen B ice shelf.

Normally, the work focuses on ice shelves. These are the floating models of ice that exists where a glacier slides into the sea.

The researchers look into these 3 factors to assess the relevance of hydrofracturing that may happen in the future of Antarctica:

The researches won’t use their hands to map the fractures. Instead of that, they used a machine that can help them to map the practice easily. First, they tried with a small area for the hand-marked fractures, then they checked all around Antarctica and identified nearly 32,000 fractures

The researchers converted to measurements and models of ice flow and temperature to figure out whether fractures are vulnerable to hydrofracturing. If there is enough tension in the ice perpendicular to the fracture, then only the hydrofracturing works.

The ice shelves that buttress the ice will be compared with the map of vulnerable fractures. And the result came out as a tension rising one. Around 60% of the area buttressing ice shelves in Antarctica should be vulnerable to hydrofracturing also.

By the end of this century, warming of air temperatures could lead to much greater amounts of surface meltwater on the ice. The most alarming problem for Antarctica has been warmer seawater eating away the ice shelves from the bottom.
