GEO 2

We have read in chapter 7 of the textbook about the various types of atmospheric disturbances of the Earth.  One of the types of disturbances that manifests itself across many areas of the globe are tropical cyclones (or as we're familiar with as - hurricanes).  Hurricanes played a major role in Al Gore's movie "An Inconvenient Truth", a 2006 documentary regarding the issue of global warming (notice the hurricane displayed on the movie poster).  Not only in the movie, but also from many other sources, it was claimed that both the frequency and intensity of hurricanes will increase due to the warming of the globe.  What is the relationship between hurricanes (tropical cyclones) and a warming globe that would suggest we will see more of them and more powerful ones?  Or is there?

Secondly, It has been well over 10 years since the movie and the case was strongly proposed for a connection between global warming and hurricane frequency and intensity.  We now have data to investigate whether the claim is true or is there something else going on?  Look into what the data over the last 10 plus years is telling us and explain what you think it says...
