Greenland's ice melting four times faster than in 2003

Greenland's ice melting four times faster than in 2003

Scientists say if all of Greenland's vast ice sheet were to melt, global sea levels would rise by 7 meters (23 feet), flooding most coastal developments around the world. But the fact that the ice is melting faster and faster, even inland, and running out as a river of water, "that's a surprise", he added. There, they melt and contribute significantly to the rise in sea level. The new study published in the Proceedings of the National Academy of Sciences discovered that Greenland's southwest region has suffered the largest sustained ice loss from early 2003 to 2013. While glaciers are smaller streams of ice that creep over the landscape and can break apart and liquefy from warm ocean water, the actual big ice sheet was believed to be more resistant to that kind of melt. One example is the pace at which sea levels are rising in the Earth's polar regions. Southwest Greenland hasn't been considered a threat when it came to Greenland ice melting.

"We knew we had one big problem with increasing rates of ice discharge by some large outlet glaciers", he said. More importantly, though, the warning concludes that faster sea level rise is inevitable without intervention.

Greenland's ice sheet is melting at an accelerated rate, faster than previously estimated.

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. The Eisverlust has increased since 2003, partly significantly, write the researchers, Michael Bevis of the Ohio State University in a study.

"We are watching the ice sheet hit a tipping point", he said, which would condemn the entire giant ice block to melting over a time scale of hundreds, or several thousand, years.

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.

That could open the way for several different outcomes, ranging from a so-called "managed no-deal" exit to another referendum. United Kingdom data disappointed, indicating shrinking business activity amid Brexit uncertainty.

Bevis said a natural weather phenomenon - the North Atlantic Oscillation, which brings warmer air to West Greenland, as well as clearer skies and more solar radiation - was building on man-made climate change to cause unprecedented levels of melting and runoff, the PTI report said. "But suddenly, because of this global warming, this relatively small fluctuation can push you over the top [and cause] a degree of melting we haven't seen before".

Humans are melting the world's ice.

Between year 2002 and 2016 Greenland lost about 280 gigatonnes of ice per year. They also found this acceleration largely took place in Greenland's southwest. Then the NAO went briefly and dramatically positive, coinciding with the ice loss pause, before dipping negative again.

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. Presently, a new study indicates how much global warming is beating another territory: Greenland.

While the amount varies from region to region, sea levels rose worldwide by an average of 20 centimetres (about eight inches) in the 20th century.
