A number of different factors can affect the formation and development of hurricanes, including sea surface temperature (SST), lower tropospheric humidity, vertical wind shear, and large-scale atmospheric circulation patterns. Which of these factors are most important and which are responsible for the increase in global hurricane intensity observed since 1970? Hoyos et al. (p. 94, published online 16 March) use a method based on Bayesian statistics and information theory to isolate the causes of the trend from short-term variability, for all of the major ocean basins where these storms occur. They conclude that only rising tropical SSTs have had a significant influence on the recent multi-decadal trend.
