The results of laboratory studies concerning self-ignition in Central Europe are presented in this paper. There are known cases of self-ignition of peatlands in Indonesia and tropical regions of Africa, as well as in Southern Europe (for example in Italy and Spain). Therefore, there is a possibility that this phenomenon could also occur in Central Europe due to a climate warming. The laboratory studies, using adiabatic calorimeters, were carried out to assess the tendency of peat to self-ignition. The main aim of ...

In 1900, just at the end of the Little Ice Age, a present day fjord valley was filled with a huge glacier, Hambergbreen, which protruded into the Barents Sea. By 1936, a weakly incised bay, named Hambergbukta, appeared at the glacier?s front due its retreat. Afterwards, the glacier?s recession and frontal retreat have continued until the end of the 1950s, when a fjord appeared. This frontal retreat was reversed by the glacier?s surge which filled up the fjord valley with the fissured glacier?s tongue just after 19...
