Almost all of the massive Greenland ice sheet begins to melt this month, a strange incident that surprised scientists.
Even the highest and coldest point of Greenland, Summit Station, showing the occurrence of liquefaction. Records of ice cores show this event happened last in 1889 and occurs once every 150 years. Three different satellites show what NASA called the melting of ice coating the island that was unprecedented. This event begins on July 8 and lasts for four days. Most of the es thick are still exist. Although the ice usually melts during the summer, this event is unusual because it happened so quickly and in a very wide area.
“There is a sweeping heat and melt the Greenland ice sheet (ice),” said NASA ice scientist Tom Wagner on Tuesday (24/7).
Melting permafrost region extends from 40 percent to 97 percent in four days, according to NASA. Until now, the melting of the ice sheets of the most extensive in the last three decades, going up to 55 percent.
According to Wagner, the researchers do not know how much of the Greenland ice sheet had melted, but it seems to start freezing again.
“If we see the ice melt in places that normally never happened before, in the long term, you are stunned and asked, what happened?” said NASA chief scientist Waleed Abdalati. “It’s the signal who very loud, which does it mean akan we were looking know within few years into the future.”
At the same time, a large iceberg off of the Petermann Glacier in northern Greenland. Snow and Ice Data Center National also announced that the ice-covered Arctic Ocean closer to a record low point.
According to Wagner and other scientists, the melting ice in Greenland has not been established because the unusual natural events or as a result of climate change. But they already know that the Greenland ice sheet is thinning certainly a result of climate change.
Summer in Greenland was warm because of the high pressure ‘parked’ in the islands, bringing warm weather that melts the ice and snow, climate experts said the University of Georgia, Thomas Mote.
According to Mote, this is the same high pressure ‘parked’ in the United States which led to drought and high temperatures.
Ohio State University ice scientist Jason Box, which recently returned from a three-week trip to Greenland said he was not wearing winter clothes when were there. Instead he wore a plain cotton pants she wears in the normal temperature, tend to be warm. “There the sun is very bright and warm, everyone was talking about how hot the weather,” said Box. “As the summer.”
