Interesting report published recently about global warming and hurricane intensity.

The study focuses not on flawed methodology of linking warming to hurricane srength, but says the data is flawed. Better equipment which more accurately can measure wind strength near the eye is being used. Older equipment was not as advanced or accurate and underestimated wind strength. So the hypothesis is that hurricanes are not increasing in strength, only that equipment is better hat is being used to take measurements.
This reminds me of when the "ozone hole" was discovered. The first time he ozone above the arctic was measured, there was a huge hole. Panic erupted. Problem was that there was no historical data to show if there was previously an ozone hole or not. Growth or shrinkage was immediately reported as good or bad news without any knowledge as to the cyclical growth or shrinkage, if any, before it was even discovered.
