Green power saved Earth from iceball fate Paris (AFP) July 1, 2009 
Vegetation helped save Earth from runaway cooling that would have encased the planet in ice, according to a study published on Wednesday. The paper sheds light on the big natural mechanisms that over hundreds of millions of years have swung the globe like a pendulum between deep chill and intense heat. Around 50 million years ago, the planet's poles were ice-free and crocodiles roamed ... read moreIce Sheets Can Retreat In A Geologic Instant 
Buffalo NY (SPX) Jun 22, 2009Modern glaciers, such as those making up the Greenland and Antarctic ice sheets, are capable of undergoing periods of rapid shrinkage or retreat, according to new findings by paleoclimatologists at the University at Buffalo. The paper, published on June 21 in Nature Geoscience, describes fieldwork demonstrating that a prehistoric glacier in the Canadian Arctic rapidly retreated in just a ... more

Greenland celebrates era of self-rule
Nuuk, Greenland (AFP) June 21, 2009Inuit choirs gathered around the port of Greenland's capital sang traditional songs Sunday to welcome a new era of self rule after 300 years under Danish authority. The prospect of global warming opening up access to Greenland's potentially rich oil and mineral wealth put an international spotlight on the ceremonies, which saw thousands of the island's 57,000 citizens gather at the port of ... more 'Brief' ice age actually lasted 30M years 
Leicester, England (UPI) Jun 18, 2009 British scientists have determined an ice age occurring about 440 million years ago that's been regarded as a brief period actually lasted 30 million years. University of Leicester geologists said their findings suggest that during the ancient ice age, global warming was curbed through the burial of organic carbon that eventually led to the formation of oil -- including the "hot shales" ... more Lifestyle melts away with Uganda peak snow cap 
Bundibugyo, Uganda (AFP) June 15, 2009When Yasamu Maate was a younger man, he could stand in his garden on a clear, cloudless morning and stare at the ice caps on Uganda's Rwenzori Mountains. But on a recent Friday the 87-year-old lamented the loss of those ice caps, which have all but disappeared, as the world around him has gotten warmer. "We used to use the snow and ice as our guide," he said, sitting on a roadside chair ... more Drilled Cores Yield Unique Arctic Climate Data 
Amherst MA (SPX) Jun 12, 2009A team of scientists from the United States, Germany, Russia and Austria returned recently from a six-month sediment drilling expedition at a frozen lake in Siberia, where they retrieved cores going back further than ever before collected in the Arctic-information they call "of absolutely unprecedented significance." Data will help scientists to understand the region's geologic climate ... more |

53 Million-Year-Old High Arctic Mammals Wintered In Darkness
Boulder CO (SPX) Jun 05, 2009Ancestors of tapirs and ancient cousins of rhinos living above the Arctic Circle 53 million years ago endured six months of darkness each year in a far milder climate than today that featured lush, swampy forests, according to a new study led by the University of Colorado at Boulder. CU-Boulder Assistant Professor Jaelyn Eberle said the study shows several varieties of prehistoric mammals ... more Melting Greenland Ice Sheets May Threaten Northeast USA And Canada 
Boulder CO (SPX) May 28, 2009A melting of the Greenland Ice Sheet this century may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax, and other cities in the northeastern United States and Canada, new research shows. The study finds that if Greenland ice melts at moderate to high rates, ocean circulation by 2100 may shift and cause sea levels off the north ... more Permafrost melt poses long-term threat, says study 
Paris (AFP) May 27, 2009Melting permafrost could eventually disgorge a billion tonnes a year of greenhouse gas into the atmosphere, accelerating the threat from climate change, scientists said Wednesday. Their probe sought to shed light on a fiercely-debated but poorly-understood concern: the future of organic matter that today is locked up in the frozen soil of Alaska, Canada, northern Europe and Siberia. ... more Microfossils Challenge Prevailing Views Of The Effects Of Snowball Earth 
Santa Barbara CA (SPX) May 28, 2009New fossil findings discovered by scientists at UC Santa Barbara challenge prevailing views about the effects of "Snowball Earth" glaciations on life, according to an article in the June issue of the journal Nature Geoscience. By analyzing microfossils in rocks from the bottom of the Grand Canyon, the authors have challenged the view that has been generally assumed to be correct for the ... more |
