11 thoughts on “Greenland’s ice is melting faster than predicted by conservative scientists – ignored by conservative politicians

    A new analysis of Greenland’s past temperatures will help scientists figure out how fast the island’s vast ice sheet is melting, according to a new report from University of Arizona atmospheric scientists. https://www.eurekalert.org/pub_releases/2017-07/uoa-fo070517.php
    The ice sheet has been shrinking since 1900 and the yearly loss of ice has doubled since 2003, other researchers have shown. The accelerated melting of the Greenland ice sheet is contributing to sea level rise. The glaciers and ice sheet of Greenland cover a land area greater than the European countries of Germany, France, Spain and Italy combined. If all Greenland’s ice melted, sea levels would rise by about 7 meters (23 feet).

  2. Update says:

    Greenland’s ice sheet is becoming smaller and smaller. The melting takes place with increased strength and at a speed that no models have previously predicted.
    Today, in the esteemed journal Scientific Reports, researchers from the Arctic Research Centre, Aarhus University, and the Greenland Institute of Natural Resources present results that, for the first time, show that the deep bottom water of the north-eastern Greenland fjords is being warmed up by heat gradually lost from the Earth’s interior. And the researchers point out that this heat loss triggers the sliding of glaciers from the ice sheet towards the sea. https://www.eurekalert.org/pub_releases/2018-01/au-hlf011818.php

    Huge iceberg threatens Greenland village (BBC 7/14/18) https://www.bbc.com/news/world-europe-44831663 A huge iceberg has drifted close to a village in western Greenland, prompting a partial evacuation in case it splits and the resulting wave swamps homes. The village’s power station and fuel tanks are also in danger. Some experts have warned that extreme iceberg events risk becoming more frequent because of climate change. This in turn increases the risk from tsunamis. In June New York University scientists released video footage of a massive 4 mile long iceberg breaking away from the Helheim Glacier in eastern Greenland. https://www.nyu.edu/about/news-publications/news/2018/july/scientists-capture-breaking-of-glacier-in-greenland-.html The calving event took place over approximately 30 minutes (condensed to 90 seconds in this video). https://www.youtube.com/watch?v=7tyfSlnMe8E The resulting iceberg would stretch from lower Manhattan up to Midtown in New York City. https://www.nyu.edu/about/news-publications/news/2018/july/scientists-capture-breaking-of-glacier-in-greenland-/jcr:content/1/par/nyuimage.img.1280.high.jpg/1530911804143.jpg

      “If you needed a visual representation of our global environmental crisis in 2018, it doesn’t get much better (well, worse) than the gigantic iceberg looming over the village of Innaarsuit in Greenland, now seen from the vantage of space.” https://earther.com/giant-iceberg-looming-over-greenland-village-is-the-per-1827652006 “On Tuesday, the European Space Agency released a satellite image snapped by Sentinel-2A on July 9 that offers another striking visual of the village’s predicament. The ‘berg, which ESA says weighs approximately 10 million tons, looms large over the village, which wouldn’t even be visible if the space agency didn’t helpfully circle it in red.”

    “Greenland ice sheet melt ‘off the charts’ compared with past four centuries” (Woods Hole Oceanographic Institution December 12, 2018) https://www.eurekalert.org/pub_releases/2018-12/whoi-gis113018.php “Melting of the Greenland Ice Sheet has gone into overdrive. As a result, Greenland melt is adding to sea level more than any time during the last three and a half centuries, if not thousands of years,” said Luke Trusel, a glaciologist at Rowan University’s School of Earth & Environment and former post-doctoral scholar at Woods Hole Oceanographic Institution, and lead author of the study. “And increasing melt began around the same time as we started altering the atmosphere in the mid-1800s.”
    This research was funded by the US National Science Foundation, institutional support from Rowan University and Woods Hole Oceanographic Institution, the US Department of Defense, the Netherlands Organization for Scientific Research, the Netherlands Earth System Science Center, and the Belgian National Fund for Scientific Research.

    Climate change: Rain melting Greenland ice sheet ‘even in winter’ (BBC news 3/7/19) https://www.bbc.com/news/science-environment-47485847 Rain is becoming more frequent in Greenland and accelerating the melting of its ice, a new study has found.
    Scientists say they’re “surprised” to discover rain falling even during the long Arctic winter.
    The massive Greenland ice-sheet is being watched closely because it holds a huge store of frozen water. And if all of that ice melted, the sea level would rise by seven metres, threatening coastal population centres around the world.”
    (BBC July 2007): “Currently the Greenland ice sheet is adding up to 1mm a year to the rise in the global average level of the oceans. It is the largest mass of ice in the northern hemisphere covering an area about seven times the size of the United Kingdom and reaching up to 3km (2 miles) in thickness. This means that the average sea level would rise around the world by about seven metres, more than 20ft, if it all melted.” https://www.bbc.com/news/science-environment-40686984

    “After Scorching Europe, Heat Wave Is Poised to Melt Greenland” https://www.livescience.com/66041-heatwave-europe-greenland.html A heat wave that shattered records in Europe this week is on the move, and it could melt billions of tons of ice in Greenland.
    Hot air that originated over Northern Africa recently brought blistering heat to Europe; yesterday (July 25), Paris sizzled at a staggering 108.7 degrees Fahrenheit (42.6 degrees Celsius), and temperature records were broken across the continent by up to 6 degrees F (3 degrees C), according to Accuweather.com.
    Today (July 26), a representative of the World Meteorological Organization (WMO) announced that atmospheric flow would carry this scorching heat to Greenland, which lost over 170 billion tons (160 billion metric tons) of ice in July and 80 billion tons (72 billion metric tons) of ice in June from surface melting alone, Reuters reported.

    When this warm air arrives in Greenland, it will likely cause “another major peak in melt area,” said Twila Moon, a research scientist with the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado.

      (8/4/19): “Greenland’s ice wasn’t supposed to melt like last week until 2070” https://thehill.com/opinion/energy-environment/456112-greenlands-ice-sheet-wasnt-expected-to-melt-like-this-until-2070 “During the past week, temperatures at the highest reaches of the Greenland ice sheet rose above freezing, melting snow at the Summit Station (10,550 feet above sea level) for the first time since July 2012 and perhaps only the third time in the last seven centuries.
      Across lower elevations around the margins of the ice sheet, bare glacial ice melted at an unprecedented rate, losing 12.5 billion tons of water on Thursday alone, with daily losses likely exceeding any point in at least the past 70 years.
      The Greenland ice sheet covers an area the size of Alaska with enough ice to raise global sea level by more than 20 feet.”
