How many glaciers are there in Washington State? The four U.S. referenceglaciers have shown an overall decline in mass balance since the 1950s and 1960s and an accelerated rate of decline in recent years (see Figure 2). Although currently glaciers make a large contribution to global sea level rise, their total contributions are eventually limited by their relatively small area. The Global Land Ice Measurements from Space (GLIMS) programme defines guidelines and rules for conducting glacier inventories3-10. Cambridge, United Kingdom: Cambridge University Press. The numbers could increase because more glaciers are getting mapped, he said. The estimate of glacier volume depends strongly on the method used, and more data are urgently required to improve the uncertainties on this estimate. Jim White, a climate scientist and interim dean of the College of Arts and Sciences at the University of Colorado Boulder, said a better measure of glacier change is ice volume, because that translates to potential sea level rise if that ice melts. According to Qin Xiang, one of the first scientists to gather data from this region, the rate at which the glaciers are melting has almost doubled since 2005.

"We just dont have the snapshots from space in 1948," Colgan said. Learn how the atmospheric temperature can increase leading to global warming, explore some of its causes and how it affects climate change, and discover the role of the greenhouse effect on global warming. ICSU (WDS)/IUGG (IACS)/UNEP/UNESCO/WMO. | Why Do We Have Seasons? The inventories should include glacier attributes, such as area, length, slope, aspect, terminal environment (calving into the sea or lake, or terminating on dry land), elevation, and glacier classification.

A better indicator of climate change is studying glacier mass, which has reduced significantly over the 20th and 21st centuries. For consistency, measurements are in meters of water equivalent, which represent changes in the average thickness of a glacier. There are approximately 186 named glaciers in Washington according to the Geographic Names Information System (GNIS). At the end of the Last Glacial Maximum, about 19,000 years ago, the vast Greenland ice sheet rapidly melted, pushing sea levels up by about ten meters. "Today, only 130,000 remain. Under IPCC scenario RCP 8.5 (a more business-as-usual scenario), global sea level contributions from glaciers will be 216 44 mm by 2100 AD14. Small glaciers tend to respond more quickly to climate change than the giant ice sheets. Now that we have a complete dataset on global glacier outlines, we can use these data to understand glacier mass balance and potential contributions to sea level rise. 9 How many glaciers are there in Washington State?
