In addition, more warm and salty [...] regional climate model for the Arctic. The model consists of several components: the atmosphere, sea ice, ocean and land. Simulations with this model help us interpret the Arctic climate, its variability and [...] climate changes in the Arctic are connected to the weather and climate in central Europe. The difficult thing about these interactions is the fact that, in addition to the Arctic factors, other aspects

On the seafloor of the shallow coastal regions north of Siberia, microorganisms produce methane when they break down plant remains. If this greenhouse gas finds its way into the water, [...] these coastal waters. As a result, the gas can be transported thousands of kilometres across the Arctic Ocean and released in a completely different region months later. This phenomenon is the subject of [...] current issue of the online journal Scientific Reports.
