Besides the trends in average values, also the extremes of temperature and precipitation are of importance for water scarcity and droughts and floods. Extremes of cold have become less frequent in Europe while warm extremes have become more frequent. Since 1880, the average length of summer heat waves over Western Europe has doubled and the frequency of hot days has almost tripled. Extreme high temperatures are projected to become more frequent and last longer across Europe over the 21^st century. There are no widespread significant trends in either the number of consecutive dry or wet days across Europe. Heavy precipitation events are likely to become more frequent in most parts of Europe. The changes are strongest in Scandinavia in winter and in northern and eastern central Europe in summer.
