I urgently need an introduction to natural disasters in Denmark! ! !

Denmark has a maritime temperate climate and the weather is changeable. January has the lowest temperature, with an average of -2.4 degrees Celsius, and July has the highest temperature, with an average of 16.6 degrees Celsius. There are only two or three days in summer when the temperature exceeds 30 degrees Celsius. Denmark has basically never experienced major natural disasters such as droughts, floods, earthquakes, etc. According to historical records, it only suffered two hurricanes in the last century, in 1902 and 1999.
