Description:In the scientific literature there have been suggestions that anthropogenic climate change (ACC) may lead to slower movement of tropical cyclones, potentially resulting in more intense precipitation in their path. Motivated by this, a recent innovative study1 suggested that over about the past 70 years there has been a considerable monotonic slowdown in translational speed in many regions of the world. Here I raise doubt as to the veracity of that finding, because the long-term changes appear to be due primarily to a few abrupt, step-like changes, both natural and artificial, in the early part of the record. This greatly reduces the likelihood that the apparent slowdown is driven primarily by anthropogenic causes.
