May 31, 2016 · Why Is Antarctica's Sea Ice Growing While the Arctic Melts? Scientists Have an Answer Global warming is melting the Arctic and glaciers worldwide, but not so much the sea ice in Antarctica. Nov 04, 2005 · Greenland's ice sheet seems to be thickening at a rate of 6.4 cm (2.6 inches) a year above altitudes of 1,500 metres (5000 feet). Below that altitude, the ice sheets are decreasing in thickness. The Greenland Ice Sheet, the mythical and huge ice cap, has attracted adventurers for centuries. You can experience it up close several places in Greenland, not least at Kangerlussuaq, where you can get up and walk on it. Greenland’s ice sheet is the second largest ice cap in the world, only surpassed by the ice cap on the Antarctic. Guest post by NedThe Greenland ice sheet has a negative mass balance, meaning that it is losing ice (Velicogna 2009, Jiang 2010). This loss occurs because the gain of new ice (in the form of snowfall within the ice sheet's interior zone of accumulation) cannot keep up with the rapid loss of ice through melting and the discharge of ice by marine terminating outlet glaciers (van den Broeke 2009). Greenland Ice Sheet, also called Inland Ice, Danish Indlandsis, single ice cap or glacier covering about 80 percent of the island of Greenland and the largest ice mass in the Northern Hemisphere, second only in size to the Antarctic ice mass.

May 31, 2016 · Why Is Antarctica's Sea Ice Growing While the Arctic Melts? Scientists Have an Answer Global warming is melting the Arctic and glaciers worldwide, but not so much the sea ice in Antarctica. As I mentioned last week, the Antarctic Ice Sheet is growing faster than we’re ever been led to believe. In fact, the Old Byrd Weather Station has been crushed in recent years by more than 50 feet of ice. The original Syple and South Pole stations are likewise buried under the ice. Mar 27, 2019 · Greenland's biggest glacier is growing for the first time in 20 years, according to Nasa. The Oceans Melting Greenland (OMG) project has recorded growth on the edges of the Jakobshavn Glacier since 2016. The findings, published in Nature Geoscience, explain that the "re-advancing, slowing and ...

Meanwhile, starting around 2000, a few studies raised the additional possibility that the Greenland Ice Sheet, contrary to what most scientists had figured, might not be comfortably stable over the next few centuries. In the warmer summers the snow on the surface would get wet, and become darker.
Nov 29, 2012 · WASHINGTON Fueled by global warming, polar ice sheets in Greenland and Antarctica are now melting three times faster than they did in the 1990s, a new scientific study says. So far, that s only ... New Class on Predicting the Effects of Climate Change on Global Forests ... Uncovering the Future of Greenland's Ice Sheet. ... Historic Shrinking of Antarctic Ice ...
Aug 15, 2016 · How old is mystery ice from the base of Greenland’s ice sheet? Some is almost a million years old, which is good news. Scott K. Johnson - Aug 15, 2016 3:22 pm UTC Dec 18, 2014 · "In August 2014, the reflectivity of the ice sheet was the lowest observed since satellite observations began in 2000. When less of the sun's energy is reflected by ice, melting increases. If all of the glacier ice on Earth were to melt, sea level would rise ~ 80 m (~ 265 ft), flooding every coastal city on the planet. If all of Earth’s temperate glaciers melted, sea level would rise ~ 0.3–0.6 m (~ 1-2 ft). If all of Greenland’s glaciers melted, sea level would rise ~ 6 m (~ 20 ft). Jan 13, 2015 · Despite fears that global warming is harming the Arctic region faster than the rest of the world, Greenland is defying climate scientists and currently growing at its fastest rate in four years. The Danish Meteorological Institute reports that Greenland’s ice sheet has seen more growth so far this year than in the last four years. Sep 14, 2017 · As a result, the ice sheet has been shrinking. According to an end of season summary from Greenland experts with the Danish Meteorological Institute, 2017 may turn out differently. According to the Institute’s preliminary estimates, about 544 billion tons more snow fell on the ice sheet between September 2016 and August 2017 than melted away.
