AGW Evidence In The Lack Of Atlantic Hurricanes

In case you missed it…the fact that the 2009 hurricane season in the Atlantic is running as one of the slowest in living memory, is evidence of…anthropogenic Global Warming!

Of course it is. Why, everybody should know by now that “global warming may spur wind shear, sap hurricanes” and that we should expect “‘fewer hurricanes’ as world warms” because “under warmer, high-CO2 conditions […[ hurricane frequency will be reduced“.

In other news: some time ago we were told that “the frequency of Atlantic storms has been rising in concert with tropical ocean temperature, probably because of global warming“.

In other other news: the only thing that appears to be able to disprove AGW would be a series of Atlantic hurricane season with zero hurricanes. But that would mean ipso facto a change in global climate, thereby once again demonstrating…AGW!

You are basically correct about the argument going on with regards to hurricanes and AGW. The argument is over the strength and not frequency of hurricanes. The connection, as you point out, is straightforward: warmer waters provide more fuel for hurricanes, AGW will cause oceans to warm, the result is stronger hurricanes when hurricanes do get going. This year was a pretty weak season (what 8 named storms?), 2 hurricanes, one of which was a major hurricane. Most of the storms which formed later in the season were torn apart by shear.

In the eastern and western pacific basins, the season was much more active, both basins producing multiple major hurricanes or super typhoons.

Rattus – you haven’t shown yet how all of that is not a mere consequence of whatever happens on a year-on-year basis. More hurricanes? AGW. Fewer hurricanes? AGW. Stronger hurricanes? AGW. Weaker hurricanes? AGW. More hurricanes here than there? AGW. And so on and so forth.

Climatology is full of just-so stories like that. There’s always an ENSO or a NAO to “blame” if things don’t follow what was predicted just a few years back.

I too am fed up with the Atlantic hurricane issue. How about calling it regional, not global, and moving on?

You might have mentioned that there are fewer hurricanes during El Ninos, and that we are currently in an El Nino.

I’m relatively new to the global warming issue. “Frequency” of hurricanes was before my time. I thought “intensity” was all that was being argued now.

And shouldn’t some acknowledgement be given to the storm track play-by-play? If the hurricane’s path takes it over an area of warmer water, it will intensify.
