Changes in growing season in Fennoscandia 1982-1999

Abstract

This study has shown large regional differences in the changes of the length of the growing season, during the period 1982-1999 in Fennoscandia. It clearly indicates that the impact on length of growing season of global warming will be different depending on the regional climate. Whether the measured changes in spring and autumn events are caused by climate change or are of a temporal and stochastic nature remains to be seen. This study also demonstrates that NOAA AVHRR data, with a method using a different threshold value applied on each individual pixel, are well suited for studying the regional impact of a changing climate even in heterogeneous and sparsely vegetated areas. © 2007 Springer-Verlag Berlin Heidelberg.
