Global Warming Science Report: Tropical Cyclone Activity

Global warming alarmists link every natural disaster to global warming. Most recently, they blamed the Australian wildfires on global warming and, of course, one cannot forget their efforts to connect global warming with Hurricane Katrina. But is this really the case. The short answer is no.

In fact, new findings from Florida State University that global and northern hemisphere tropical cyclone activity is still the lowest in thirty years and will likely continue down that path [1]:

Tropical cyclone (TC) activity worldwide has completely and utterly collapsed during the past 2 to 3 years with TC energy levels sinking to levels not seen since the late 1970s. This should not be a surprise to scientists since the natural variability in climate dominates any detectable or perceived global warming impact when it comes to measuring yearly integrated tropical cyclone activity. With the continuation (persistence) of colder Pacific tropical sea-surface temperatures associated with the effects of La Nina, the upcoming 2009 Atlantic hurricane season should be above average, as we saw in 2008. Nevertheless, since the Atlantic only makes up 10-15% of overall global TC activity each year (climatological average during the past 30 years), continued Northern Hemispheric and global TC inactivity as a whole likely will continue.”

As Heritage Senior Policy Analyst Ben Lieberman writes, natural disasters are just that: natural [2]. They will occur with or without global warming and their frequency or intensity cannot be linked to global warming.
