A short update on Koeppen climate shifts in Europe between 1901 and 2003

The question is investigated how far global warming in the period 1901-2003 will affect the region of Europe. For this purpose, changes of the climate zones that exist according to Koeppen will be analysed. The trends and outliers in terms of expansion and location of individual climate types are used as statistical indicators of climate change. The most important results of this study are: a) a significant increase of the extension of the climate types BS and Cr; b) a significant decrease of the extension of the climate types Dc and Ec; c) the largest changes are observed within the last two decades. These changes are discussed in relation to the mean conditions of temperature and precipitation. Moreover, significant correlations between the area extensions of climate types and the NAO index could be found.
