    The European warming will be higher than the global mean temperature increase. As can be seen in Fig. this temperature increase is different from region to region and season to season. In the autumn and winter months the temperature change in North and Eastern Europe will be higher (up to 3 °C) compared to South Europe (1– °C).

      The Abisko Station has also collaborated with some SCANNET Stations to introduce remotely operated photographic observations of winter snow cover. One development in was the establishment of an eddy correlation tower together with automated chambers to monitor CO 2 fluxes in the birch forest and its understory (Heliasz et al. ). It is clear that winter snow cover is an effective thermal buffer against severe air temperatures in polar areas, and as this protection is reduced, becomes intermittent or is completely lost, the effects on some species may be profound; some freeze-tolerant species cannot survive through repeated freeze—thaw cycles, the winter-enhanced

      To better understand the diversity of lake responses to climate change and give managers insight on individual lakes, we modelled daily water temperature profiles lakes in Michigan If snow accumulates on top of the land surface, a new layer is added on top of the DEM as described in Zanotti et al. (). Surface boundary conditions are given by hydrometeorological measurements (rainfall, temperature, wind velocity), regionalized as described in Bertoldi ().
