NOAA climate scientist Thomas Knutson is invited to give a presentation on global warming and hurricanes as part of a science seminar series on Capitol Hill sponsored by the American Meteorological Society. The presentation is cleared by the NOAA, but there is nonetheless concern about the title of his lecture—“Global Warming and Hurricanes.” Scott Carter, an NOAA legislative affairs officer, sends an email to NOAA official Ahsha Tribble asking her to comment on it. “I wanted to get your thoughts on him using the term global warming,” Carter says. “His title slide is ‘Global Warming and Hurricanes.’ I see the event does ask that, and I am no scientist, but I know that term is sensitive, so any problem in him using the term?” Some time later Knutson is advised not to use the term “Global Warming” in his title. “Just a heads-up… wouldn’t want the higher ups coming down on you. There is discomfort in the administration with these terms.” Knutson ignores the request. [Maassarani, 3/27/2007, pp. 10 pdf file]

The Journal of Climate publishes a paper by hurricane expert Robert Tuleya and NOAA climate scientist Thomas Knutson suggesting that an increased concentration of carbon dioxide in the atmosphere may increase the intensity of hurricanes. Knutson’s study is based on computer analysis performed at the Commerce Department’s Geophysical Fluid Dynamics Laboratory in Princeton, N.J. The two scientists created some 1,300 virtual hurricanes using a more powerful version of the same supercomputer simulations that the NOAA uses to track and predict the behavior of real hurricanes. The New York Times reports that according to independent experts “this study is particularly significant… because it used half a dozen computer simulations of global climate, devised by separate groups at institutions around the world.” MIT climate scientist Kerry A. Emanuel says Knutson’s study “is by far and away the most comprehensive effort” to analyze the issue using computer simulations. [New York Times, 9/30/2004; Tuleya and Knutson, 2005 pdf file]

Rick Rosen, the assistant administrator for the NOAA’s Office of Oceanic and Atmospheric Research, contacts Ahsha Tribble and suggests that the agency issue a press release to publicize a piece by climate scientist Chris Landsea that will be published several months later in the Journal of Climate. Landsea’s article, dealing with the issue of hurricane intensity and climate change, takes a position that is supportive of the Bush administration’s view on the issue. Rosen writes in an email, “It challenges the conclusions reached by Knutson and Tuleya (2004) (see September 28, 2004) regarding the potential for more intense hurricanes in a warmer climate. It is not likely to attract the same media attention as the original Knutson and Tulyea [sic] paper, but we should consider drafting a NOAA press release nonetheless.” Often, proposed press releases suggesting a link between human activity and global warming or global warming and hurricane intensity are delayed because of the “politically sensitive” nature of the topic. Sometimes they are not published at all. Such was the case for the 2004 Knutson and Tuleya study referred to by Rosen. Knutson submitted a press release on the paper, but it was never approved (see Before September 28, 2004). [Maassarani, 3/27/2007, pp. 30 pdf file]

Thomas Knutson, a research meteorologist with the agency’s Geophysical Fluid Dynamics Laboratory in Princeton, NJ, recieves an interview request from CNBC television for its program “On the Money.” Knutson forwards the request to NOAA public affairs officer Kent Laborde for approval, as is required by NOAA’s media policy (see September 29, 2005). Laborde then directs the request to Chuck Fuqua, deputy director of communications at the Department of Commerce, who asks: “What is Knutson’s position on global warming vs. decadal cycles? Is he consistent with [Gerry] Bell and [Chris] Landsea?” (Bell and Chris have views that are more in line with the Bush administration’s position on global warming) Laborde then calls Knutson and asks him about his views on the future trend of Atlantic hurricane activity. Laborde then writes to Fuqua, saying that “he is consistent, but a bit of a different animal. He isn’t on the meteorological side. He’s purely a numerical modeler. He takes existing data from observation and projects forward. His take is that even with worse [sic] case projections of green house gas concentrations, there will be a very small increase in hurricane intensity that won’t be realized until almost 100 years from now.” Two minutes later Fuqua responds, “Why can’t we have one of the other guys on then?” Knutson is then informed that the interview request has been declined.

NOAA public affairs officer Carmeyia Gillis mentions in an email to colleagues Kent Laborde, Jana Goldman, and John Leslie that media inquiries submitted to the Climate Prediction Center concerning climate change should first be cleared by senior political administrators James R. Mahoney or Ahsha Tribble. [Maassarani, 3/27/2007, pp. 17 pdf file]

Reporter Peter Lord of the Providence Journal calls the NOAA public affairs office and requests an interview with scientist Thomas Knutson, the author of a 2004 paper (see September 28, 2004) suggesting that increased carbon dioxide in the atmosphere may increase the intensity of hurricanes. Lord speaks with public affairs officer Kent Laborde, who tells him that NOAA has discounted research linking global warming to more intense hurricanes. “What we’ve found is, if you look at a couple segments of science, observational or modeling, there is no illustrated link between climate change and hurricane intensity,” Laborde says. “We actually have periods of intensity followed by periods of lower intensity. We have evidence of periods going back to the 1930s. It follows a clear pattern.” When Lord says he would like to interview Knutson, Laborde asks, “What is the topic?” Lord says he wants to talk about Kerry Emanuel’s “theories linking climate change to worsening hurricanes.” Laborde responds, “Chris Landsea would be better. He’s an observational scientist.” Unlike Knutson, Landsea does not believe hurricane intensity is influenced by global warming.
