An anomalous return of the Odden ice tongue suggests unusual Arctic conditions

Data from many sources, including NASA, have shown a significant decrease in Arctic sea ice since 1979. However, the processes driving the melting and freezing of sea ice are complex, and fluctuations occur throughout the year. Short-term variations in temperature, winds, ocean convection and water salinity within a certain region can also affect how much ice can reform or melt.
