Northern Norway reports abnormally warm start to October
Night-time temperatures of 15-16 degrees Celsius in Norway are not normal for the time of year.
The northern part of the country in particular has had an unusually warm start to October.
Bodø, the capital of the North Norway county, registered a temperature of 16.5 degrees on the first day of the month, an all-time record for the location, NRK reports.
Warm evenings in the north have continued since, with the other days in October seeing night temperatures between 12 and 15 degrees.
The weather has also been dry, with only small amounts of rain since the beginning of this month.
Other locations including Kristiansand, Arendal, Værnes and Bergen have also experienced record high temperatures for October, according to the broadcaster’s report.
But the north of the country is showing the most marked trend.
“There is a clear trend. North Norway has had the most warming generally, including in the autumn,” Met Norway researcher Helga Therese Tilley Tajet told NRK.
“North Norway is the region (in Norway) which has had the highest warming since 1900. The autumn, along with spring, is the season which has increased most,” she also said.
Tajet cited global warming as the cause for the measured increases. But several factors are involved in the relatively faster warming in the north, she said.
“Less snow cover results in higher warming up when the sun is out. Less sea ice means the sea gets more heat from the sun,” she said.
“It is concerning that heat record after heat record is being broken. September was the warmest (September) ever measured globally,” she added.
