The story about the research explains further

“You don’t need to sell your beach real estate yet, because melting of these large ice sheets will take from centuries to a few thousand years,” explained louis vuitton sunglasses Rutgers geologist Kenneth Miller in this story. “The current trajectory for the 21st century global rise of sea level is 2 to 3 feet (0.8 to 1 meter) due to warming of the oceans, partial melting of mountain glaciers, and partial melting of Greenland and Antarctica.” In a perspective essay titled "Regional Sea-Level Projection", appearing in the same issue of Science, Josh Willis of the Jet Propulsion Laboratory and John Church with the Centre for Australian Weather and Climate Research warn that scientists must investigate sea level rise and make more precise estimates before it's too late. "Without adaptation, a rise by (20 inches) would displace 3.8 million people in the most fertile part of the Nile River Delta," they wrote. "A rise by (6.5 feet) could displace 187 million people globally. Credible projections of sea-level rise in the 21st century are essential for devising adaptation or mitigation measures. Yet, present estimates of future sea-level rise are too imprecise to inform such decisions." This newest study led by Moon focused specifically on the velocity of Greenland’s big-dog outlet glaciers as they flow toward their crackling oblivion in the ocean -- a louis vuitton mens sunglasses 2012 small, but significant piece of the world’s total ice-destruction prospects. The faster these glaciers move, the more ice and meltwater they ultimately add to the sea. In previous studies, scientists have conjured scenarios where Greenland glaciers doubled this rush toward destruction, or even accelerated tenfold, with sea level rising anywhere from four to 19 inches by 2100 as a direct result. But no one knew for sure how fast the glaciers were actually traveling in the real world. In the new study, funded by NASA and the National Science Foundation, Moon and team took a detailed glimpse at most of Greenland’s 206 biggest glaciers. Using three louis vuitton sneakers for men 2012 satellites, the scientists examined glacier motion in the winter of 2000-01 and then repeated the process for each winter from 2005-06 through 2010-11. Based on data from 178 glaciers between 2000 to 2005, and another 195 observed between 2005 and 2010, they found that the velocity of these colossal ice rivers had not surged as much as some studies projected. "In some sense, this raises as many questions as it answers. It shows there's a lot of variability," explained co-author Ian Joughin, a glaciologist in the UW's Applied Physics Laboratory and Moon's doctoral adviser. "We can't look at one glacier for 100 years, but we can look at 200 glaciers for 10 years and get some idea of what they're doing.” The results were complicated. The story about the research explains further. The scientists cautioned that 10 years was too short of a window to pin down the long-term dynamics of Greenland’s ice. Monitoring and research must continue. With more data, and a longer horizon, Greenland’s contribution could surprise us all. (And not in a good way.)
