Antarctic have already been in news for the long period. A study has been conducted on this which states that global sea levels could rise at a significantly higher rate than had been predicted earlier and Antarctic ice is melting regularly.
Glaciologist Hamish Pritchard of the British has research Antarctic Survey (BAS) theory. It has been found that Antarctica’s massive ice shelves are shrinking because they are being eaten away from below by warm water, a new study finds. That suggests that future sea levels could rise faster than many scientists have been predicting. The western side of Antarctica is shedding 23 feet of ice sheet each year, from a mixture of causes, most of which are man-made.
With the help of NASA ICES at satellite, which recorded 4.5 million measurements over five years, the BAS discovered that 20 of Antarctica’s 54 ice shelves across Antarctica were actually being melted from below, by warm water, rather than warmer air caused by global warming. It is believed that changes in wind currents pushed warmer water towards the ice shelves.
This means that a larger amount of ice is melting in the area than was previously thought.
The cause of the wind change itself was because of man-made greenhouse gases and the hole in the ozone layer. As long as warm water will keep encircling the continent, it will provide “a further push from the wind”. It can cause newer areas start shrinking.
