    Throughout the last ice age, the climate changed repeatedly and rapidly during so-called Dansgaard-Oeschger events, where Greenland temperatures rose between 5 and 16 degrees Celsius in decades. When certain parts of the climate system changed, other parts of the climate system followed like a series of dominos toppling in succession. This is the conclusion from an analysis of ice-core data by a group of researchers that included postdoc Emilie Capron and associate professor Sune Olander Rasmussen from the Section for the Physics of Ice, Climate and Earth at the Niels Bohr Institute, University of Copenhagen, in Denmark.
    CLIMATE CHANGE:

    Abrupt ice age climate changes behaved like cascading dominoes

    Researchers the world over have long believed that 70 percent of the universe is composed of dark energy, a substance that makes it possible for the universe to expand at an ever-increasing rate. But in a new study, University of Copenhagen researchers tested a model which suggests that the universe’s expansion is due to a dark substance with a kind of magnetic force. Should the model stand, it means that dark energy simply doesn’t exist, according to the UCPH professor behind the study.

    For the first time ever, researchers have found fossils under Greenland's ice sheet that are so large and well preserved that they can be seen with the naked eye. The fossils reveal several million years of details about climate and plant life in Greenland according to the UCPH researcher behind the discovery.
