Description

This image shows Hurricane Katrina a few hours before it struck Louisiana, resulting in flooding and catastrophic damage to New Orleans. This hurricane resulted in ~$80 billion dollars of damage[1] and killed at least 1700 people [2], making it the deadliest hurricane in the United States since 1928 and the most expensive natural disaster in United States history.

History of tropical storms, hurricanes and major hurricanes in the North Atlantic, as well as several major milestones in the technology used to study hurricanes. It is likely that during most of this record the number and severity of hurricanes was underestimated due to inadequate techniques and incomplete coverage.

It is impossible to connect Katrina or any other specific hurricane to global warming[3]; however, extreme weather events in general, and Katrina in particular, often increase public interest in global warming and lead to considerable speculation on whether a link exists[4]. The best available evidence is that global warming should cause a moderate increase in storm intensity[5][3], and some suggest that this has already been observed[6]. However, many scientists believe that the natural fluctuations in hurricane frequency and intensity are sufficiently large, and the expected signal sufficiently small, that it is unlikely that any connection could be established at the present time[3][5].
