Increasing trends in regional heatwaves
Perkins-Kirkpatrick & Lewis (2020) conducted a study to determine the regional and global observed heatwave trends in frequency and intensity, using the Berkeley Earth temperature data set and the key heatwave metrics. The study showed that in almost all regions, there was an increase in the frequency of heat waves which was observed to be rapid and significant. Additionally, the study revealed an acceleration in the intensity and duration of heat waves since the 1950s. A deduction from the study reveals that a reduction in the heatwave frequency and intensity can only occur due to several factors; one such factor is if there is room for availability and accessibility of urban green spaces.
