The number of warm days in Sweden with at least 30 degrees has more than doubled in the last decade, compared to the previous measurement period.
This is shown by an examination where Sveriges Radio's Ekot has processed the Swedish Meteorological and Hydrological Institute's historical temperature data.
In the last decade, Sweden has on average had 14 days per summer with temperatures above 30 degrees or more. During the previous reference period, 1961-1990, it was six times per summer.
The heat has also been noticed in more places than before. Days with 30-degree heat have been unusual in northern Sweden, but are now occurring more often.
We're starting to get a climate in Sweden where we'll need to start adapting, says Christofer Åström, researcher at Umeå University to the radio.
He points out the danger of the heat. The body is directly affected when it gets hot, especially among older people, which contributes to the cardiovascular system having to work harder. This increases the risk of getting sick or dying.
The record summer of 2018 is estimated to have resulted in around 600 people dying due to the heat.
