Climate change has already brought major changes to the Arctic, and still greater ones are expected in the future. Svalbard stands on the verge of a new climate characterised by winters lacking temperatures below -20°C, less sea ice and a longer growing season in summer.

The MOSJ climate indicators provide information on changes in the Svalbard climate in the atmosphere, in the sea and on land. Since there are large natural variations in the Arctic, it is important to monitor the climate indicators over a long period.
