Rising sea levels and Greenland's glacial melt have not increased as fast as previously predicted, but ice loss has still increased 30 percent over the last decade, and sea level rises have endangered low-lying coasts, according to a new report published in the May issue of Science. Previous studies estimated that glaciers would double their ice loss by 2010 and continue at that speed, and the actual flow of ice rivers has caused "significantly less" of an increase in sea level rise. However, the team analyzing the data estimated that glaciers may eventually flow faster than earlier studies predicted. The study based its findings on data stretching back to 2000. "There is the caveat that this 10-year time series is too short to really understand long-term behaviour," said co-author Ian Howat from Ohio State University. The researchers also said that, while we are not in the worst-case scenario, the glacier melt is speeding up and there is no sign of it stopping.
