Nature (17 December 2015) Albedo isn’t everything 2012 was a whopper summer for melting on Greenland; by 12 July of that year fully 98% of the ice sheet was covered in liquid water according to satellite data At one weather station a layer of ice as much as a meter thick melted in 4 days That brief episode and a subsequent 2-day melt contributed to 14% of the season’s ice loss But a recently published modeling study of the 2012 melting showed it wasn’t sun falling on darkened snow that drove the melt—in fact the skies were pretty cloudy over much of the island during the two melting events Instead it was warm temperatures and rainfall provided by big "blocking" high-pressure systems that kept the mild weather in place As the Arctic warms such melt episodes are likely to "occur much more frequently in the future" says Dirk van As of the Geological Survey of Denmark and Greenland in Copenhagen Earlier this year climate scientist Marco Tedesco of Columbia University published data supporting an earlier proposal that the retreat of Arctic sea ice has disrupted the polar jet stream causing weather systems to meander more slowly from west to east The topography of the ice sheet also plays a role in the accelerating melt Each increase in temperature drives the upper edge of the melt zone farther inland and higher up the ice sheet But because the ice sheet is steep at its edges but flatter toward the middle each successive degree of warming exposes a larger area of ice to melting than the last This nonlinear response to warming means that about 60% more meltwater was released from the ice sheet over the past decade than would have been the case if the ice slope were uniform scientists estimated in a recent paper Researchers hope to incorporate all of these factors into computer models of ice sheets which still struggle to mimic how real ice sheets respond to climate change In a recent comparison of four ice models for example the amount of meltwater they produced under current conditions varied by more than 40% Forecasts of future ice sheet behavior appear even more uncertain: Under the same high–global warming scenario eight ice sheet models predicted anywhere between 0 and 27 cm of sea level rise in 2100 from Greenland melt Better melt models would improve forecasts not only for Greenland but also for the Antarctic Ice Sheet It holds 10 times more water than Greenland and for now is losing nearly all of its ice through glacier calving not surface melting But sooner or later the thaw will reach the bottom of the world In the meantime the modelers working back in their cozy offices want to know more about the feedbacks driving Greenland’s decline One key question is how meltwater that drains to the base of the ice sheet affects the glaciers’ march to the ocean and the rate at which they shed icebergs Researchers also wonder how meltwater flows unleashed in the spring affect summer runoff Scientists have recently discovered that during spring melt-and-freeze cycles massive "ice lenses" as thick as 6 m form just below the snow surface Data from sensors in the snow suggest that the lenses block summer meltwater from percolating into deeper older snow known as firn Instead the meltwater is apparently getting trapped near the surface amplifying summer flows Next spring Tedesco will participate in a 150-km trek by snowmobile across southeast Greenland in –30°C temperatures to see how widespread the phenomenon is "It’s going to be pretty brutal but there’s no other way to get the data" he says Melting brings other challenges for field research as Black and Bloom researchers discovered last year when they tracked their "pixel" of eroding ice The researchers faced endless slush and puddles and a weekly chore of moving their working and sleeping quarters as the ice disappeared around them leaving the tents stranded on bizarre pedestals half a meter high But they also felt a sense of wonder at the transformation of the icescape McQuaid says "Each evening we marveled as the sun went low enjoying the fact that we were somewhere no one else had been and would never be again because of the melt" Reporting for this story was supported by the Pulitzer Center on Crisis ReportingWritten by ANI | Nevada | Published: November 18 2009 3:40 pm Related News Couples Retreat,but the consultancy related to business improvement, 2009 5:58 am Top News The Small Industries Development Bank of India (SIDBI), So, Any pickling that was done with the indigenous fruits of the season, 2016 12:02 am Top News Two weeks after being elected US President, 2017 12:22 am FIFA has published a list of 36 referees to attend a World Cup seminar from Nov.
