Climatic Changes in Scandinavia

Flowering rape field in November 2009

After October with night frost in several places November has been on the warm side of the freezing point in Denmark. Not one of DMI's meteorological stations has measured just one case of night frost in November and the frost will not appear in the first days to come. Statistically it is unlikely that November ends without frost, this has not happened in Danish weather-history which goes back to 1873. The mildest November until now was in 2000. But today is the 27th of November and still very mild - it seems that the record is about to be beaten.

There were many fields with yellow rape-flowers last Saturday, not as bright yellow as in May of course - and there are small cautious flowers in cherry and magnolia trees.

There is a large focus on the climatic changes and their negative influence on nature. The poles and archipelagos are in risc of being flooded, but the changes are also seen in several other places, i.e. in Scandinavia. The changes do not only strike single species or habitats in the North; the influence is broad on all levels, says a new report about climatic changes in the North, worked out by Nordisk Ministerråd. Their basis were 14 various species, which are indicators and meant to show the influence of the climatic change in various ecosystems. By following these indicators it is possible to follow more general tendencies instead of an indivual development progress. The earlier beginning of the pollen season, the changed distribution of the fish populations and changes in the behaviour pattern of the birds are just a few examples of that the climatic changes have already secured a foothold.

The report is in English and can be downloaded on:
