The tropical-cyclone data analysed in this study were taken from the International Best Track Archive for Climate Stewardship (IBTrACS; https://www.ncdc.noaa.gov/ibtracs/, file ftp://eclipse.ncdc.noaa.gov/pub/ibtracs/v03r10/all/csv/Allstorms.ibtracs_all.v03r10.csv). Indices of a variety of the most commonly cited regional climate modes of variability were obtained from several sources: the Earth System Research Laboratory (ESRL; https://www.esrl.noaa.gov/psd/data/climateindices/), the National Centers for Environmental Information (NCEI; https://www.ncdc.noaa.gov/teleconnections/), the National Center for Atmospheric Research (NCAR; https://climatedataguide.ucar.edu/climate-data/), the University of East Anglia (UEA; https://crudata.uea.ac.uk/cru/data/nao/) and the British Antarctic Survey (BAS; http://www.nerc-bas.ac.uk/public/icd/gjma/newsam.1957.2007.seas.txt).
The FORTRAN code used to perform the change-point analyses6 is available from the author on request.

Extended data figures and tables
Each bar represents the trend (km h−1 yr−1) corresponding to one of the nine scenarios given in Extended Data Table 4. Since some scenarios are redundant for a given basin, only the first occurrence is plotted. Stippling indicates significance at the 5% level based on a two-tailed Student’s t-test. Each panel corresponds to a different region: GL (a), NH (b), SH (c), NA (d), EP (e), WP (f), NI (g), SP (h) and SI (i).
This file contains the Supplementary Methods, including sections describing: preparation of the storm track data and computation of translational speeds; Bayesian information criterion (BIC) analyses; generation of the curves in Fig. 2 and miscellaneous statistical considerations
