Climate Change Is Pushing Greenland Over the Edge<\/a><\/h3>\n

New data from Greenland shows that modern warming is outpacing even historically warm eras like the Medieval Warm Period.<\/strong><\/p>\n<\/header>\n

Matthew Osman stands atop an ice cap in western Greenland looking out over the Nuussuaq Peninsula. In the distance and more than 2,000 meters below, the village of Ilulissat is a tiny speck in the vast expanse of snow and ice. As Osman steps into the snow, he sinks into a crevasse up to his thigh. Carefully easing his way out, he\u2019s reminded of the hazards of working on ice. Like others who have ventured to drill into Greenland\u2019s ice, Osman and his colleagues are braving the dangers to search for clues as to how the climate has changed in the past, and, by extension, how it may change in the future. What they\u2019ve found is an unexpected sign of just how acute ongoing climate change really is.<\/p>\n

The research team led by Osman, a geoscientist at the University of Arizona, came to Greenland to extract a 140-meter-long ice core. This core stretches nearly to bedrock and, in the gases and chemicals housed within, holds evidence of climate change over the past 2,000 years.\u00a0Their analysis of the core<\/a>\u00a0shows that in this place during the Medieval Warm Period,\u00a0a roughly 400-year phase<\/a>\u00a0of higher global temperatures around 1,000 years ago, the ice was growing thicker and advancing\u2014the opposite of what it\u2019s doing today.<\/p>\n
