Hurricanes and Global Warming: Is There a Connection?

Furthermore, they note that research on possible future changes in hurricane frequency due to global warming has produced studies that "give such contradictory results as to suggest that the state of understanding of tropical cyclogenesis provides too poor a foundation to base any projections about the future.".....Perhaps of greatest significance of all to the issue of future hurricanes and the destruction they will cause is the nature and degree of human occupation of exposed coastal locations.

Several prominent scientists and a host of climate alarmists have claimed that the intense Atlantic hurricane seasons of 2004 and 2005, together with their considerable human and economic impacts, were linked to CO2-induced global warming. To help set the record straight on this important issue, Pielke et al. (2005) review what is fact and what is fiction about the matter.

With respect to hurricane numbers, the five scientists report that "globally there has been no increase in tropical cyclone frequency over at least the past several decades," citing the studies of Lander and Guard (1998), Elsner and Kocher (2000) and Webster et al. (2005) in support of this statement. Furthermore, they note that research on possible future changes in hurricane frequency due to global warming has produced studies that "give such contradictory results as to suggest that the state of understanding of tropical cyclogenesis provides too poor a foundation to base any projections about the future."

With respect to hurricane intensity, Pielke et al. note that Emanual (2005) claims to have found "a very substantial upward trend in power dissipation (i.e., the sum over the life-time of the storm of the maximum... more [truncated due to possible copyright]  
Several prominent scientists and a host of climate alarmists have claimed that the intense Atlantic hurricane seasons of 2004 and 2005, together with their considerable human and economic impacts, were linked to CO2-induced global warming. To help set the record straight on this important issue, Pielke et al. (2005) review what is fact and what is fiction about the matter.

With respect to hurricane numbers, the five scientists report that "globally there has been no increase in tropical cyclone frequency over at least the past several decades," citing the studies of Lander and Guard (1998), Elsner and Kocher (2000) and Webster et al. (2005) in support of this statement. Furthermore, they note that research on possible future changes in hurricane frequency due to global warming has produced studies that "give such contradictory results as to suggest that the state of understanding of tropical cyclogenesis provides too poor a foundation to base any projections about the future."
 
With respect to hurricane intensity, Pielke et al. note that Emanual (2005) claims to have found "a very substantial upward trend in power dissipation (i.e., the sum over the life-time of the storm of the maximum wind speed cubed) in the North Atlantic and western North Pacific." However, they report that "other studies that have addressed tropical cyclone intensity variations (Landsea et al., 1999; Chan and Liu, 2004) show no significant secular trends during the decades of reliable records." In addition, they indicate that although early theoretical work by Emanuel (1987) "suggested an increase of about 10% in wind speed for a 2°C increase in tropical sea surface temperature," more recent work by Knutson and Tuleya (2004) points to only a 5% increase in hurricane windspeeds by 2080, and that Michaels et al. (2005) conclude that even this projection is likely twice as great as it should be.
 
Perhaps of greatest significance of all to the issue of future hurricanes and the destruction they will cause is the nature and degree of human occupation of exposed coastal locations. By 2050, for example, Pielke et al. report that "for every additional dollar in damage that the Intergovernmental Panel on Climate Change expects to result from the effects of global warming on tropical cyclones, we should expect between $22 and $60 of increase in damage due to population growth and wealth," citing the findings of Pielke et al. (2000) in this regard. Based on this evidence, they state without equivocation that "the primary factors that govern the magnitude and patterns of future damages and causalities are how society develops and prepares for storms rather than any presently conceivable future changes in the frequency and intensity of the storms."
 
In concluding their review, Pielke et al. note that many climate alarmists continue to claim a significant hurricane-global warming connection for the purpose of advocating massive anthropogenic CO2 emissions reductions that "simply will not be effective with respect to addressing future hurricane impacts," additionally noting that "there are much, much better ways to deal with the threat of hurricanes than with energy policies (e.g., Pielke and Pielke, 1997)."
 
We agree. We should be doing the right things for the right reasons. Anything less not only hurts us, it debases us.
