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...

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...

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...

A sediment core from a South American lake revealed a steady, sharp drop in crucial monsoon rainfall since 1900, leading to the driest conditions in 1,000 years as of 2007 and threatening tropical populations with water shortages, a team from Pitt, Union College, and SUNY-Albany reports in PNAS A 2,300-year climate record University of Pittsburgh researchers recovered from an Andes Mountains lake reveals that as temperatures in the Northern Hemisphere rise, the planet's densely populated...

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...

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...

The steady retreat of glaciers on China's Qinghai-Tibet plateau during the past 40 years is troubling, scientists in the Asian nation said Wednesday. Xin Yuanhong, senior engineer in charge of a three-year field study, said the glaciers at the headwaters of the Yangtze, China's longest river, now cover 406 square miles, down from 482 square miles in 1971, Xinhua reported. The scientists said the melting, enough to fill Beijing's largest reservoir, was occurring at a worrisome speed, the...

COLUMBUS, Ohio (AP) - An earth sciences professor at Ohio State University was named Tuesday to receive a National Medal of Science from the White House, the university announced. Lonnie Thompson, a glaciologist, received the medal for his work providing evidence of global climate change. He is one of eight researchers who will receive the award this summer during a White House ceremony. Thompson has worked for nearly three decades, leading more than 50 research expeditions to ice caps and...
