The Least Sea Ice In 800 Years
Copenhagen, Denmark (SPX) Jul 03, 2009
New research, which reconstructs the extent of ice in the sea between Greenland and Svalbard from the 13th century to the present indicates that there has never been so little sea ice as there is now. The research results from the Niels Bohr Institute, among others, are published in the scientific journal, Climate Dynamics. There are of course neither satellite images nor instrumental ... read more

Plants Put Limit On Ice Ages
Palo Alto CA (SPX) Jul 03, 2009
When glaciers advanced over much of the Earth's surface during the last ice age, what kept the planet from freezing over entirely? This has been a puzzle to climate scientists because leading models have indicated that over the past 24 million years geological conditions should have caused carbon dioxide levels in the atmosphere to plummet, possibly leading to runaway "icehouse" conditions. ... more

  • 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 ... more

    Ice Sheets Can Retreat In A Geologic Instant
    Buffalo NY (SPX) Jun 22, 2009
    Modern 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, 2009
    Inuit 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

    Spring Agricultural Fires Have Large Impact On Melting Arctic
    Durham NH (SPX) Jun 08, 2009
    Scientists from around the world will convene at the University of New Hampshire to discuss key findings from the most ambitious effort ever undertaken to measure "short-lived" airborne pollutants in the Arctic and determine how they contribute in the near term to the dramatic changes underway in the vast, climate-sensitive region. The two-year international field campaign known as POLARCA ... more

    Unstated Assumptions Color Arctic Sovereignty Claims
    Ottawa, Canada (SPX) Jun 05, 2009
    Settling the growing debate over ownership of Arctic Ocean resources is complicated by the fact that the various countries involved have different understandings of the geography of the place. Phil Steinberg, an associate professor in the Department of Geography at Florida State University in Tallahassee, says coming to terms with those divergent views is the first necessary step to ... more

    53 Million-Year-Old High Arctic Mammals Wintered In Darkness
    Boulder CO (SPX) Jun 05, 2009
    Ancestors 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, 2009
    A 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
