Within the realm of climate change / global warming alarmism, there are scientists who practice admitted fraud, such as Peter Gleick, then there are those who practice incompetence - meet the extraordinarily "incompetent" Jeff Masters of wunderground.com
The global warming alarmism science community has an alarming number of fraudsters (google Fakegate and Climategate), and it has an overabundance of pathological exaggerators and serial incompetents: meet Jeff Masters, per one of his critics.
Steve Goddard of Real-Science has been tracking the proclamations and predictions of the Wunderground's weather "guru" with much glee and entertainment.
Steve has identified how Masters always takes current individual severe weather events and then claims the event is unprecedented or unusual in weather history. Unfortunately for the public (and Wundergound's reputation) Jeff is always wrong a lot and Steve takes no prisoners in pointing out the unequivocal and accelerating incompetence.
