Abstract
Increases in global mean temperatures have caused the climate to change, affecting the frequency and magnitude of extreme events. Series of daily minimum temperatures for the period 1951-2014 has been analyzed in Sweden. It was found that cold extremes such as frost days, cold spells and annual minimum temperatures all show significant warming trends with a statistical significance of 90%. Frost days show a decrease of 0.4 frost days/year and days below the 10th percentile show a decrease of 0.3 days/year. Annual minimum temperatures have increased by 0.07 °C/year. There are more southerly stations than northerly showing warming trends, although they are not significant. From a societal perspective a decrease in cold extremes would... (More)

There are more southerly stations than northerly showing warming trends, although they are not significant. From a societal perspective a decrease in cold extremes would indicate that wildlife, agriculture and energy sectors will have to adapt to a different climate. The Swedish society must thus consider its vulnerability and exposure within different sectors and systems and make decisions regarding climate adaptation. (Less)
