1. Melting Point Greenland

2013 National Headliners Award First Prize Environmental Reporting:
“In the summer of 2012, one of the most vital ecosystems on earth, the Greenland ice sheet, experienced a meltdown that alarmed scientists the world over. Greenland is an island encased in ice and it’s the world’s second largest ice sheet after Antarctica. That summer, ninety-seven percent of the surface ice melted. “Melting Point” is a comprehensive examination of this event. Videographer Snorre Wik shot the footage under tough conditions—hauling around 1,000 pounds of gear by helicopter, by SUV (on Greenland’s mostly dirt roads) and out on a thinning ice sheet made treacherous by the sun. Wik improvised to get the shots he needed—lying on helicopter floors to steady his camera without a gyro-stabilized mount, or holding his DSLR by hand on the dashboard of SUVs. His efforts were both breathtaking and disturbing.
Additionally, Jens Christiansson is responsible for filming the destruction of the Watson River bridge. Marco Tedesco and his team of researchers filmed the moulins and ice cap during the record meltoff.”
2. Huge Lakes Found Under Greenland’s Ice Cap!

Scientists using satellite images and data from NASA’s Operation IceBridge have found evidence of a drained and refilled subglacial lake beneath northeastern Greenland’s Flade Ice Cap. This sub-ice body of water is only one of a handful that have been detected in Greenland and its presence sheds new light on how the Greenland Ice Sheet reacts to warming temperatures.
3. What Scientists Are Seeing Over Greenland

Why are scientists out flying over Greenland, drilling into its ice, and monitoring it from space? The answer is that they see it as a bellwether of future Earth. Scientists are sampling, drilling, and flying over this great island because they believe it may be a bellwether of future Earth. Greenland is two million square kilometers of land… 81% of which is covered by a giant central ice cap, the Inland Ice. Here is 2.8 million cubic kilometers of ice… layered and packed over the millennia. Its thickest points lie beneath two massive ridges… the northern at 3 kilometers thick, the southern over 3.2 kilometers.
The Inland Ice basin is framed by parallel mountain ranges. Its bedrock basement floor is down near sea level… depressed by the weight of the ice above it. If this ice sheet were to melt, the land beneath would be underwater, dotted with small islands. Over time, with the weight lifted, it would gradually rise. Today, the sheer mass of the Inland Ice exerts a gravitational pull on surrounding oceans. This pull raises sea levels all around the island.
In the event of extreme melting, a recent study showed that sea levels would actually drop out to a distance of about 1000 kilometers. More distance shores, however, would experience an average global sea level rise of over 7 meters.
