Climate and climate change
The word ”climate” denotes a statistical summary of weather patterns over a certain span of time (often 30 years). Twenty per cent of the earth has a polar climate, which means that the area is characterised by cold summers and no month of the year has an average temperature exceeding 10°C. Climate change denotes changes in major weather patterns over a long time-scale, and results from both natural variability and the influence of human activities.
The causes underlying climate change are complex and include many different feedback mechanisms that either enhance or counteract climate change. In polar regions, changes observed in sea ice, snow cover and glaciers can provide knowledge about climate change.
