From the IPCC we know:

Based on a range of models, it is likely that future tropical cyclones (typhoons and hurricanes) will become more intense, with larger peak wind speeds and more heavy precipitation associated with ongoing increases of tropical SSTs. There is less confidence in projections of a global decrease in numbers of tropical cyclones. The apparent increase in the proportion of very intense storms since 1970 in some regions is much larger than simulated by current models for that period. {9.5, 10.3, 3.8}

But if we look at the cyclone data for 2007 we see the following:

Seems like the cumulative impact of cyclones is fizzling, so doesn't that mean that Global Warming has reversed course into Global Cooling by this measure? *

* This is a rhetorical question meant to illustrate the stupidity of the underlying premise that Global Warming increases hurricane intensity.
