Washington, Nov 11: Scientists from 10 European nations working together in the European Project for Ice Coring in Antarctica (EPICA) have established a precise link between climate records from Greenland and Antarctica using data on global changes in methane concentrations derived from trapped air bubbles in the ice.
In a research appearing in the journal Nature, the scientists concluded that though the climate records looked different, they is a similarity in temperatures and weather patterns caused by changing currents in the Atlantic Ocean.
The Antarctic ice core analyses were performed on the new EDML (EPICA Dronning Maude Land) ice core, while the Greenland ice core analyses was performed on the North Greenland Ice core Project (NGRIP).
Based on the new synchronized time scale the scientists were able to compare high-resolution temperature proxy records from north and south.
Their analysis revealed that a bipolar seesaw occurred systematically between the north and south hemisphere, causing really dramatic climate changes during the glacial period.
Scientists from Belgium, Denmark, France, Germany, UK, Italy, the Netherlands, Norway, Sweden and Switzerland participated in the study.
