9. According to the WGI, it is very likely that the number and intensity of hot days have increased markedly in the last three decades and virtually certain that this increase will continue into the late 21 st century. In addition, it is likely that the occurrence of heat waves (multiple days of hot weather in a row) has more than doubled in some locations, but very likely that there will be more frequent heat waves over most land areas after mid-century.
