Read here. There are scientists from the past and present who have managed to command center stage of the world's press despite their known incompetencies. Kevin Trenberth is one such scientist. The media just plain love his shrill, non-scientific hysteria that human CO2 emissions cause cherry-picked weather disasters, yet the man has no empirical, scientific evidence to back it up.
Case in point: hurricanes.
In the U.S., no hurricanes have made landfall in nearly 3 years.
In 2004 though, Trenberth proclaimed that hurricane frequency and intensity would increase, using only the highly speculative AGW hypothesis as his base of hysterical predictions - a definite non-expert, non-empirical fabrication.
An actual IPCC hurricane expert at the time took very serious issue with Trenberth's hurricane incompetence and fabrication of AGW-caused hurricane activity:
"It is beyond me why my colleagues would utilize the media to push an unsupported agenda that recent hurricane activity has been due to global warming. Given Dr. Trenberth’s role as the IPCC’s [coordinating] Lead Author responsible for preparing the text on hurricanes, his public statements so far outside of current scientific understanding led me to concern that it would be very difficult for the IPCC process to proceed objectively with regards to the assessment on hurricane activity...I was disappointed when the IPCC leadership dismissed my concerns when I brought up the misrepresentation of climate science while invoking the authority of the IPCC. Specifically, the IPCC leadership said that Dr.Trenberth was speaking as an individual even though he was introduced in the press conference as an IPCC lead author; I was told that that the media was exaggerating or misrepresenting his words, even though the audio from the press conference and interview tells a different story…and that Dr.Trenberth was accurately reflecting conclusions from the [2001 Climate Bible], even though it is quite clear that [it] stated that there was no connection between global warming and hurricane activity. The IPCC leadership saw nothing to be concerned with in Dr. Trenberth’s unfounded pronouncements to the media…"
Obviously, Trenberth is a highly incompetent scientist, based just on his frequent wild-assed speculations that seemingly are always wrong. If the climate science community is ever wanting to be believed by the American public, they need to jettison Trenberth and his likes from the public podium and taxpayer funded research - it's a no-brainer.
