Hurricane Katrina: Possible Causes

Hurricane Katrina devastated New Orleans and other Gulf Coast communities when it blew ashore on August 29, 2005. This essay discusses current thinking among experts on whether global warming may be contributing to the increased strength of hurricanes. It includes the results of a study using statistical data dating back to the nineteenth century that suggests hurricanes are lasting longer and reaching higher peak wind speeds, and a paper reporting that precipitation during hurricanes in the United States has increased seven percent during the 20th century. There is also a link to a video that discusses hurricane prediction and how it effects cities like New Orleans. A background essay and list of discussion questions are also provided.
