Arctic Fossil Record Traces Greenland Ice Sheet's Past
2013-11-23 05:24:05

April Flowers for redOrbit.com - Your Universe Online There have been many studies telling us how small the Greenland ice sheet is today. A new study, published in the journal Geology, reveals that the ice sheet was actually smaller between 3,000 and 5,000 years ago. Surprisingly, the sheet was as small during this period as it has ever been in recent history. The international research team used a new technique they developed for interpreting the Arctic fossil record. “What’s...

Moraine Research May Alter Thinking On Climate’s Effect On Glaciers

redOrbit Staff & Wire Reports - Your Universe Online A Dartmouth College-led study published in the latest edition of the journal Quaternary Geochronology describes a newly discovered, more accurate method to date the soil and rock debris left behind by high altitude tropical glaciers. The research could alter pre-existing interpretations of how climate change affected equatorial ice masses, the study authors explained in a statement Tuesday. Currently, scientists use a variety of...

The landform known as a drumlin, created when the ice advanced during the Ice Age, can also be produced by today's glaciers. This discovery, made by researchers from the University of Gothenburg, Sweden, has just been published in the scientific journal Geology. Drumlins generally consist of an accumulation of glacial debris "“ till "“ and are found in areas that were covered by ice sheet. As the ice advanced, it moved rocks, gravel and sand and created tear-shaped raised ridges...

A new study that reports precise ages for glacial moraines in southern Peru links climate swings in the tropics to those of Europe and North America during the Little Ice Age approximately 150 to 350 years ago. The study, published this week in the journal Science, "brings us one step closer to understanding global-scale patterns of glacier activity and climate during the Little Ice Age," says lead author Joe Licciardi, associate professor of Earth sciences at the University of New Hampshire....

 The U.S. Geological Survey has released the results of a long-term study of key glaciers in western North America, reporting this month that glacial shrinkage is rapid and accelerating and a result of climate change. University of Illinois geologist William Shilts spent nearly two decades studying glaciers on Bylot Island, an uninhabited island about 300 miles southwest of Thule, Greenland. He, his students and other geologists who followed in his footsteps have chronicled the decline...

According to a paper in this week's issue of the journal Science, the vast majority of the world's glaciers are retreating as the planet gets warmer.  For the last 7,000 years, New Zealand's largest glaciers have moved out of step with glaciers in the Northern Hemisphere, showing strong regional variations in climate, the paper reported. "This research should provide much more accurate reconstructions of glacial advances worldwide, allowing us in turn to make climate models more...

A melting glacier and flash flooding fears at a Canadian park on Baffin Island forced officials to evacuate tourists and declare much of the area off-limits. The Auyuittuq National Park on the island's northeast coast recently witnessed record-breaking warmth and substantial amounts of rain, Parks Canada spokeswoman Pauline Scott told Canwest News Service. This summer's events are beyond anything we're used to, Scott said from Iqualuit, Nunavut. This is no doubt a result of climate...

ESA -- This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows flow features most likely formed by glaciers or 'block' glaciers. This unusual 'hourglass'-shaped structure is located in Promethei Terra at the eastern rim of the Hellas Basin, at about latitude 38º South and longitude 104º East. A so-called 'block' glacier, an ice stream with a large amount of scree (small rocks of assorted sizes), flowed...
