Newly discovered Greenland mega canyon sends water to the sea
2013-08-30 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Researchers have found a "mega canyon" in Greenland tucked under a mile and a half of ice that could rival the size and depth of Arizona's Grand Canyon. While the discovery won't become a major tourist attraction, it does provide insight into how meltwater courses its way underneath the world's second-largest ice sheet, and how that might affect ice shelves and glaciers at its periphery. Melting ice from Greenland and Antarctica is now the dominant contributor to global sea level rise, which is expected...

Deep Ice Canyon Found Far Below Greenland Surface
2013-08-30 04:06:00| Climate Ark Climate Change & Global Warming Newsfeed
Environment News Service: Using ice-penetrating radar, scientists have discovered a long, deep canyon that exists a mile beneath the Greenland ice sheet, data from a NASA airborne science mission and an international research team reveals. The scientific team identified a continuous bedrock canyon that extends from almost the center of the island and ends at its northern extremity in a deep fjord connecting to the Arctic ocean. The canyon looks like a winding river channel at least 460 miles (750 kilometers) long, making...
Huge canyon under Greenland ice
2013-08-29 20:00:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: One of the biggest canyons in the world has been found beneath the ice sheet that smothers most of Greenland. The canyon - which is 800km long and up to 800m deep - was carved out by a great river more than four million years ago, before the ice arrived. It was discovered by accident as scientists researching climate change mapped Greenland's bedrock by radar. The British Antarctic Survey said it was remarkable to find so huge a geographical feature previously unseen. The hidden valley...

How Greenland may become greener
2013-08-28 08:37:00| Climate Ark Climate Change & Global Warming Newsfeed
Daily Mail: Climate change could bring about the greening of Greenland by the end of the century, scientists predict. Today only four indigenous tree species grow on the island, confined to small areas in the south and three quarters of the world's most most sparsely populated country is covered by a barren ice sheet. But by the year 2100 swathes of verdant forest could be covering much of its land surface, potentially changing the landscape and making life difficult for arctic animals, according to experts....
Climate change could turn Greenland green by 2100

Guardian: Climate change could bring about the greening of Greenland by the end of the century, scientists predict. Today only four indigenous tree species grow on the island, confined to small areas in the south. Three-quarters of Greenland, the world's most sparsely populated country, is covered by a barren ice sheet. But by the year 2100 swaths of verdant forest could be covering much of its land surface, according to experts. "Greenland has .. the potential to become a lot greener," said lead...
