Recent studies have shown these natural drainpipes, called moulins, can speed up the slow seaward march of the grinding ice by lubricating the interface with bedrock below. Now, though, a new Dutch study of 17 years of satellite measurements of ice movement in western Greenland concludes that the speedup of the ice is a transient summertime phenomenon, with the overall yearly movement of the grinding glaciers not changing, and actually dropping slightly in some places, when measured over longer time spans. The work, the authors and other experts caution, does not mean that more widespread surface melting could not eventually destabilize vast areas of the world's second-largest ice storehouse. But for the moment, the study, which is being published in Friday's edition of the journal Science, throws into question the notion that abrupt ice losses in Greenland are nigh. "The positive-feedback mechanism between melt rate and ice velocity appears to be a seasonal process that may have only a limited effect on the response of the ice sheet to climate warming over the next decades," said the paper. "with the overall yearly movement of the grinding glaciers not changing, and actually dropping slightly in some places, when measured over longer time spans" The glaciers have not accelerated!

About Dot Earth Andrew C Revkin on Climate Change By 2050 or so, the world population is expected to reach nine billion, essentially adding two Chinas to the number of people alive today. Those billions will be seeking food, water and other resources on a planet where, scientists say, humans are already shaping climate and the web of life. In Dot Earth, reporter Andrew C Revkin examines efforts to balance human affairs with the planet's limits. Supported in part by a John Simon Guggenheim Fellowship, Mr Revkin tracks relevant news from suburbia to Siberia, and conducts an interactive exploration of trends and ideas with readers and experts. wind power Access to cheap energy underpins modern societies. Finding enough to fuel industrialized economies and pull developing countries out of poverty without overheating the climate is a central challenge of the 21st century. arctic melt Enshrined in history as an untouchable frontier, the Arctic is being transformed by significant warming, a rising thirst for oil and gas, and international tussles over shipping routes and seabed resources. water troubles Human advancement can be aided by curbing everyday losses like the millions of avoidable deaths from indoor smoke and tainted water, and by increasing resilience in the face of predictable calamities like earthquakes and drought. wildlife Earth's veneer of millions of plant and animal species is a vital resource that will need careful tending as human populations and their demands for land, protein and fuels grow.

Up on Mount Shasta, the glaciers are not behaving like you'd expect. Mount Shasta, at 14,162 feet seems to have a mind of its own these days. What has surprised scientists about the glacier is that if the theories about global warming are true, the glacier ought to be shrinking, but it's not. "Unlike most areas around the world, these glaciers are advancing, they are growing. Thirty percent in the last fifty years," says scientist Erik White. White and mountain climber Chris Carr are Shasta experts. But the glacier changes dramatically, year to year," says Carr. So why are the glaciers larger today than they were a century or more ago? "Mount Shasta is right at the very northern end of areas influenced by El Nino and were at the southern end of areas affected by La Nina. So between the two we get to see the benefits of that which means more snow and rain in this area," says White. Snow scientists have been tracking the glaciers' size by comparing photos from a century ago to those taken decades later, and then using satellite data and computer modeling to determine the rate of growth. Those models predict Shasta will continue to receive more than normal snowfall, but if the temperature continues to rise, the glaciers will begin to recede. For now, the growing glaciers are good news to the town of Mount Shasta which hosts the thousands of tourists who come to here to experience the thrill of ice climbing. You can climb mountain Shasta all the way to the glaciers to see for yourself, but, you'd better have good hiking equipment and be in good shape too!
