  1. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. There is also no trend in the frequency of major hurricanes (Cat 3 +) for the same period, although the trend for the last 20 years is downwards. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades.
