There’s now clear evidence that effects of global warming have reached the remote, high-elevation areas of central-north Greenland. The years 2001 to 2011, were the warmest in the past 1,000 years, with the region now 1.5 °C warmer than during the 20th century. The Greenland Ice Sheet plays a pivotal part in the global climate system. With enormous amounts of water stored in the ice (about 3 million cubic kilometers or almost 8 million gallons), melt and resulting sea-level rise is considered a potential tipping point. For unmitigated global emissions rates the ice sheet is projected to contribute up to 50 centimeters to global mean sea-level by 2100.
