Glacier Cores From Eastern European Alps May Yield New Climate Clues
2012-01-10 05:41:00

Researchers are beginning their analysis of what are probably the first successful ice cores drilled to bedrock from a glacier in the eastern European Alps. With luck, that analysis will yield a record of past climate and environmental changes in the region for several centuries, and perhaps even covering the last 1,000 years.  Scientists also hope that the core contains the remnants of early human activity in the region, such as the atmospheric byproducts of smelting metals. The...

The National Snow and Ice Data Center reports that Arctic sea ice continues to shrink each summer to nearly record low levels, with this year´s ice loss the second-lowest ever since records first began being taken in 1979. Despite only a few decades worth of records, a new study, published in the British journal Nature, found that “both the duration and magnitude of the current decline in sea ice seem to be unprecedented for the past 1,450 years,” reported the authors. The...

An international team of scientists, led by Dr Stephen Barker of Cardiff University, has produced a prediction of what climate records from Greenland might look like over the last 800,000 years. Drill cores taken from Greenland's vast ice sheets provided the first clue that Earth's climate is capable of very rapid transitions and have led to vigorous scientific investigation into the possible causes of abrupt climate change. Such evidence comes from the accumulation of layers of ancient...

EVANSTON, Ill., July 11, 2011 /PRNewswire/ -- Since 1998, climate scientists have attempted to reconstruct global annual temperature over the last millennium using natural proxies such as tree rings and ice cores. However, a new study finds substantial uncertainty in these reconstructions. In their research, Professors Blakeley McShane of the Kellogg School of Management at Northwestern University and Abraham Wyner of the Wharton School at the University of Pennsylvania find that natural...

Application deadline is June 20, 2011; deployments to take place between July 12 and July 19, 2011 The National Science Foundation (NSF) is accepting written requests from professional journalists to report on research--including studies of the ice sheet, climate change and atmospheric chemistry--supported in Greenland by NSF's Office of Polar Programs (OPP). OPP and NSF's Office of Legislative and Public Affairs (OLPA) jointly manage and coordinate media visits to the Polar Regions. NSF...

The end of the Norse colonies on Greenland have long been shrouded in mystery, and while archaeologists have been able to fill in some blanks, there is limited written evidence of the colony's demise in the 14th and early 15th century. But now, new research from Brown University suggests that Greenland's early Viking settlers lived in a region with a rapidly changing climate with temperatures plunging several degrees on average in a span of decades. Climate scientists have been able to...

Cooling trend could be on the way unless thwarted by greenhouse gasses There's an old saying that if you don't like the weather in New Mexico, wait five minutes. Maybe it should be amended to 10,000 years, according to new research. In a letter published recently in the journal Nature, Los Alamos National Laboratory researchers and an international team of scientists report that the Southwest region of the United States undergoes "megadroughts""”warmer, more arid periods lasting...

Scientists took samples in New Jersey for latest research Twenty thousand years of massive volcanic eruptions doubled the level of carbon dioxide (CO2) in Earth's atmosphere 200 million years ago, according to research by Rutgers geologists published recently in the journal Science. Morgan Schaller, Jim Wright and Dennis Kent report that the level of atmospheric CO2 went from about 2,000 parts per million to 4,000 parts per million and then shrank back to pre-eruption levels over the next...

Research project completes drilling for the year, reaching two miles below West Antarctic Ice SheetOn Friday, Jan. 28 in Antarctica, a research team investigating the last 100,000 years of Earth's climate history reached an important milestone completing the main ice core to a depth of 3,331 meters (10,928 feet) at West Antarctic Ice Sheet Divide (WAIS). The project will be completed over the next two years with some additional coring and borehole logging to obtain additional information and...
