It's also interesting to note that
overall global trends in the T2 data sets are more divergent, but there is no apparent step in 1992.

the overall global trend of increasing hurricane intensity, the key issue of concern raised by our study is that the hurricane intensities in the North Atlantic for the last decade have been lower than elsewhere on the globe.
I think that
the overall global trend is still moving towards a colder regime but only slowly.
