Six noted tropical cyclone experts wrote a paper in the Bulletin of the American Meteorological Society titled "Hurricanes and Global Warming." Their three main points were: No connection has been established between greenhouse gas emissions and the observed behavior of hurricanes. The scientific consensus is that any future changes in hurricane intensities will likely be small and within the context of observed natural variability. Finally, the politics of linking hurricanes to global warming threatens to undermine support for legitimate climate research and could result in ineffective hurricane policies.
Stanley Goldenberg, a meteorologist at the Hurricane Research Division of the National Oceanic & Atmospheric Administration, says, "Katrina is part of a well-documented, multidecadal scale fluctuation in hurricane activity. This cycle was described in a heavily cited article printed in the journal Science in 2001." His colleague Chris Landsea agrees, saying, "If you look at the raw hurricane data itself, there is no global warming signal. What we see instead is a strong cycling of activity. There are periods of 25 to 40 years where it's very busy and then periods of 25 to 40 years when it's very quiet."
About the connection between hurricanes and global warming, Goldenberg concludes, "I speak for many hurricane climate researchers in saying such claims are nonsense." The bottom line for President Bush is that unless he's God, he shouldn't accept the blame for Hurricane Katrina.
