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...

Scientists studying the world's most enigmatic lake have only 165 feet left to drill as time is running out. Vostok is a sub-glacial lake in Antarctica, hidden about 13,000 ft beneath the ice sheet. With the Antarctic summer almost over, temperatures will soon start to drop. Scientists will leave the remote base on February 6, when conditions are still mild enough for a plane to land. The team has not stopped drilling for weeks. "It's like working on an alien planet where no one has been...

Raimund Muscheler is a researcher at the Department of Earth and Ecosystem Sciences at Lund University in Sweden. In the latest issue of the journal Science, he and his colleagues have described how the surface water temperature in the tropical parts of the eastern Pacific varied with the sun's activity between 7 000 and 11 000 years ago (early Holocene). Contrary to what one might intuitively believe, high solar activity had a cooling effect in this region. "It is perhaps a similar...


Word of the Day

  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
