Peru Ice Cap Shrinking Due To Warming Temps, Not Less Snowfall
2014-02-26 12:56:35

Brett Smith for redOrbit.com - Your Universe Online When we think about how climate change is shrinking glaciers around the world – we are probably imagining the massive sheets of ice around the Earth’s polar regions. However, glaciers do exist in tropical latitudes, albeit at extremely high elevations, and a new study in the journal Geology has found that one of these tropical glaciers is shrinking as a result of warming temperatures – not lower snowfall levels as some scientists...

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...

Glacier Cores From Eastern European Alps May Yield New Climate Clues

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...

Written by Earle Holland, Ohio State University One of the world's foremost experts on climate change is warning that if humans don't moderate their use of fossil fuels, there is a real possibility that we will face the environmental, societal and economic consequences of climate change faster than we can adapt to them. Lonnie Thompson, distinguished university professor in the School of Earth Sciences at Ohio State University, posed that possibility in a just-released special climate-change...

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...

American glaciologist Lonnie Thompson has spent decades on glaciers drilling ice cores and has never come across a situation that is now occurring on top of Puncak Jaya -- a three-mile high glacier located in the Sudirman Range in the western central highlands of Papua province, Indonesia. Thompson had hoped to chronicle the affect of global warming on the last remaining glacier in the Pacific. But what he found has worried him even more. As he set up camp he could hear the ice melting...

The majestic snow-capped summits of Africa's Mount Kilimanjaro are melting quickly "” so quickly, in fact, that the ancient mountain's ice sheet could completely disappear within 20 years, says a US study released on Monday. In the study, published in the journal Proceedings of the National Academy of Sciences, climatologists reported that the ice cap crowning Kilimanjaro's peak shrank by some 85 in the nearly hundred years between 1912 and 2007.  Even more disturbing, ...

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...

Two abrupt and drastic climate events, 700 years apart and more than 45 centuries ago, are teasing  scientists who are now trying to use ancient records to predict future world climate. The events "“ one, a massive, long-lived drought believed to have dried large portions of Africa and Asia, and the other, a rapid cooling that accelerated the growth of tropical glaciers "“ left signals in ice cores and other geologic records from around the world. Lonnie Thompson, University...

Roughly 2 billion Asians will experience water shortages in the coming decades as global warming diminishes glaciers on the Tibetan Plateau, scientists warned on Friday.The plateau has more than 45,000 glaciers that accumulate during the region's snowy season, before they drain into Asia's main rivers, which include the Yellow, Yangtze, Brahmanputra and Mekong. Some scientists refer to the plateau as the "Third Pole" due to its massive glacial ice sheets. However, temperatures on the plateau...
