Scientists Say That the Greenland Ice Sheet Is Melting Very Fast

The research provides fresh evidence of the dangers posed to vulnerable coastal places as diverse as Miami, Shanghai, Bangladesh and various Pacific islands as climate change shrinks the world's land-based ice.

However, scientists in the newly published study say they realize there is another major source of ice melt, in the country's southwest region, which is mostly devoid of large glaciers.

The Bevis led study, published Monday in the Proceedings of the National Academy of Sciences, analysed Global Positioning System data from Greenland's coast to more precisely understand previous research from a joint project between NASA and the German Aerospace Center. In spite of the fact that ice sheets are still the significant contributor to sea-level rise, the researchers foresee that it's increasing, melting in southwest Greenland will become a major player in the future.

"By limiting greenhouse gas emissions we will limit warming, and thus also limit how rapidly and intensely Greenland affects our coastal communities through sea level rise", Trusel said.

Greenland was losing ice four times faster in 2012 than it was in 2003, new research has found. "But now we recognise a second serious problem: Increasingly, large amounts of ice mass are going to leave as meltwater, as rivers that flow into the sea", he added.

"We're going to see faster and faster sea level rise for the foreseeable future", Bevis grimly summed up.

However, the National Geographic report said, Greenland is dwarfed by the Antarctic ice sheet, which could raise sea level 57 meters if fully melted.

Greenland's ice sheet is melting at an alarming rate which is now four times faster than 16 years.

Speaking about the study, the Ohio State University's professor of geodynamics and lead author of the study Michael Bevis said that the research found humanity may have passed the point of no return when it comes to combating climate change.

A United States research team examined ice cores from western Greenland that record the behaviour of the ice sheet dating back to 1650.

Scientists believe global warming is to blame - and the findings could have serious implications for coastal USA cities including NY and Miami, as well as island nations particularly vulnerable to rising sea levels. Now, the new study revealed that Southwestern Greenland region is also melting at a faster rate than the researchers expected.

The rate at which the ice is melting across the island was far from steady.

The Greenland ice sheet covers nearly the entire island and extends over 1.7 million square kilometers.

The ice above the Arctic Circle is disappearing far quicker than experts previously thought, and it's feared this will lead to faster sea level rises as Earth's atmosphere continues to warm. When combined with man-made global warming, the effects are "supercharged".

Even more, both Southwest Greenland and Eastern Antarctic Ice Shelf were deemed as safe regions, not affected by global warming and ice sheet meltdown. It meant sea levels rose by about 0.03 inches annually.

Researchers say the accelerated ice loss is caused by a combination of global warming, as well as the North Atlantic oscillation, a periodic weather phenomenon that brings warmer air to western Greenland.
