Greenland Ice Melt Has 'Gone Into Overdrive,' Says Scientists

Ice loss from Greenland is one of the key drivers of global sea level rise, according to the study.

Previous studies have shown that the Greenland ice sheet may disappear completely by the middle of next century. A contemporary study portrays this enormous melt out wasn't only an irregularity juxtaposed with the last 40 years but the last 350. It suggests that if the trend of warmer summers continues causing unprecedented rates of melting it could accelerate the already fast pace of sea level rise. Researchers also provided more firm evidence of how much the surface around the Arctic has been melting due to rapid climate change.

From these numbers, the researchers estimated that ice sheet-wide levels of meltwater runoff have jumped 50 per cent in the past 20 years compared with pre-industrial times.

In July 2012, a spate of warm weather caused almost the entire surface of the Greenland ice sheet to begin melting, an event with no precedent in the satellite record.

The Test rankings will next be updated at the conclusion of the two-Test series between New Zealand and Sri Lanka. This was hugely significant for New Zealand, who so rarely win series of three tests or more away from home.

They found that the surface of Greenland's ice sheet melts on summer days.

Today, these rates are "off the charts", said glaciologist Sarah Das, who is a co-author of the study, published this week in the journal Nature.

The group analyzed ice layers spanning 350 years and found that the amount of Greenland ice sheet disintegrating was "exceptional" and that minimal but continued warming at present could inflict additional damage to the ice. This threatens cities such as London and Venice and entire nations such as the Maldives, which within decades could be swallowed by the rising level of the sea.

'We found a 50 per cent increase in total ice sheet meltwater runoff since the start of the industrial era, and a 30 per cent increase since the 20th century alone'. Instead of escaping the ice sheet, the short-lived meltwater forms icy bands that stack up layers of densely packed ice over time.

The next entry into the visceral, gore-ridden fighting franchise also has a release date, and is due to launch April 23rd, 2019. If you haven't heard of it, that's because it's an original, as announced on the official Mortal Kombat Twitter account.

The cores of the drilling contained records of past melts, which allowed the scientists to extend their records back to the 17th century.

The team analysed these results in combination with the imaging data collected by various satellites and the data from sophisticated climate models, which enabled them to determine the rate of ice melting, not only at core site, but also broadly across Greenland.

Study co-author Matt Osman, a graduate student, said: "We have had a sense that there's been a great deal of melting in recent decades, but we previously had no basis for comparison with melt rates going further back in time".

"We need to be aiming for net-zero emissions before 2050". "So the ice sheet's response to human-caused warming has been non-linear".

Mika Singh ‘held in Dubai for harassing Brazil teen’
Singer Mika Singh has been detained in United Arab Emirates (UAE) after a girl complained against him for alleged harassment. A 17-year-old Brazilian model has accused Mika of sending "indecent photos" with promising her a role in a Bollywood movie.

In the wake of October's dire report from the UN Intergovernmental Panel on Climate Change warning that civilization has just more than a decade to stave off climate catastrophe, Thursday's report spells more bad news for the planet, especially the millions of people living near the world's oceans. Ice core samples were brought back to the labs at the U.S. National Science Foundation Ice Core Facility in Denver, Colorado., WHOI in Woods Hole, Massachusetts, Wheaton College in Norton, Mass, and the Desert Research Institute in Reno, Nevada.
