Peruvian Ice Cores Reveal History Of Earth's Tropical Climate
2013-04-05 13:11:38

April Flowers for redOrbit.com - Your Universe Online Earth's tropical climate history has been revealed in unprecedented detail — year by year, for almost 1,800 years — by two annually dated ice cores drawn from the tropical Peruvian Andes. In 2003, a research team led by Ohio State University retrieved core samples from a Peruvian ice cap. They noticed some startling similarities to ice cores they had gathered from Tibet and the Himalayas. Even though the cores were taken...

West Antarctic Ice Sheet Warming Faster

redOrbit Staff & Wire Reports - Your Universe Online A portion of the Antarctic ice sheet is warming nearly twice as quickly as experts had previously believed, which could increase the region's future contribution to rising sea levels, a team of researchers from the Ohio State University (OSU) has discovered. According to BBC News Environmental Correspondent Matt McGrath, the study authors analyzed temperature records from Byrd Station, a scientific outpost in the center of the...

80-Year-Old Photos Aid In Greenland Ice Melt Study
2012-05-30 09:11:47

Researchers from Denmark´s University of Copenhagen have gained new insight into the loss of ice mass in Greenland´s glaciers thanks to a chance discovery of 80-year-old photo plates discovered in a Danish basement. It is often difficult for scientists to assess the scale and speed of Arctic ice melt, but the extremely rare photos provide them with a more accurate picture. Greenland´s ice was rapidly melting in the 1930s, followed by a cooling period in middle of the 20th...

  Researcher Alun Hubbard, of the Center for Glaciology at Aberystwyth University said he was rendered “speechless” when a glacier about twice the size of Manhattan he and his team have been tracking appeared close to breaking off, reports MSNBC. In 2009, scientists installed GPS masts on the Petermann Glacier to track its movement and in August of last year, the “calving” event of the glacier, where it separates itself from land, began following the tides...

Written by Pam Frost Gorder, Ohio State University The northernmost mummified forest ever found in Canada is revealing how plants struggled to endure a long-ago global cooling. Researchers believe the trees -- buried by a landslide and exquisitely preserved 2 to 8 million years ago -- will help them predict how today's Arctic will respond to global warming. They also suspect that many more mummified forests could emerge across North America as Arctic ice continues to melt. As the wood is...

Glaciologists who drilled through an ice cap perched precariously on the edge of a 16,000-foot-high Indonesian mountain ridge say that the ice field could vanish within in the next few years, another victim of global climate change. The Ohio State University researchers, supported by a National Science Foundation grant and the Freeport-McMoRan mining company and collaborating with Meteorological, Climatological and Geophysical Agency (BMKG) Indonesia and Columbia University, drilled three ice...

NASA-funded researchers monitoring Greenland's Jakobshavn Isbrae glacier report that a 7 square kilometer (2.7 square mile) section of the glacier broke up on July 6 and 7. The calving front "“ where the ice sheet meets the ocean "“ retreated nearly 1.5 kilometers (a mile) in one day and is now further inland than at any time previously observed. The chunk of lost ice is roughly one-eighth the size of Manhattan Island, New York. Research teams led by Ian Howat of the Byrd Polar...

Researchers spent two months this summer high in the Peruvian Andes and brought back two cores, the longest ever drilled from ice fields in the tropics. Ohio State glaciologist Lonnie Thompson said that this latest expedition focused on a yet-to-be-named ice field 5,364 meters (17,598 feet) above sea level in the Cordillera Blanca mountain range. The researchers hiked to a col, or saddle, between two adjacent peaks "“ Hualcán and Copa "“ set up camp and used a ground sensing...

U.S. scientists have used deep ocean sediment to reconstruct an ancient climate record dating to more than 500,000 years. Ohio State University researchers said the sediment -- trapped within the top 65.6 feet of a 1,312-foot sediment core drilled in 2005 in the North Atlantic Ocean -- has provided new information about the four glacial cycles that occurred during that period. We've now generated a climate record from this core that has a very high temporal resolution, one that is...

 Researchers watching the loss of ice flowing out from the giant island of Greenland say that the amount of ice lost this summer is nearly three times what was lost one year ago.The loss of floating ice in 2008 pouring from Greenland's glaciers would cover an area twice the size of Manhattan Island in the U.S., they said."We now know that the climate doesn't have to warm any more for Greenland to continue losing ice," Box said.  "It has probably passed the point where it could...
