Hot year
According to NASA, the year of 2016 may be the hottest so far.
Danish meteorologists (DMI) have reported that September 2016 was one of the hottest and sunniest in history.
Although the average temperature was 16.2 degrees, which corresponds to record years of 1999 and 2006, the average maximum daily temperature reached 20.5 degrees, which breaks previous records.
DMI also measured 201 hours of sunshine and only 35 millimetres of rainfall, which is about half of the precipitation in a typical September.
