Greenland - global warming
Gerth Gundel readies his harpoon while fishing between the icebergs in the Disko Bay. He is worried about the rising temperatures, the influx of freshwater in the oceans from the melting glaciers, the potential of changing ocean currents.
The Jakobshavn glacier is probably the fastest moving ice stream in Greenland, and in mid August 2015, scientists from the European Space Agency reported that a 12,5 square kilometer chunk of ice had broken loose.
According to researchers at the Danish Meterological Institute, the Greenland ice sheet is shrinking at an alarming speed. Nearly ten cubic kilometres of ice melts every day, dumping freshwater into the ocean. The ice sheet plays an important role in cooling down the planet, as 90 percent of sunlight is reflected back out into the atmosphere. Losing the Greenland ice due to man made global warming will rise sea levels by up to 20 feet, disrupt the ocean currents by diluting the salinity and accelerate the heating of the planet.
