1. Over the past century, tornado deaths in the U.S. have been declining significantly. Have the number of observed tornadoes gone down as well? Is there any relationship between these two variables? What does this tell us about cause-and-effect relationships? Over this time period, how has the impact of tornadic storms on U.S. society changed and why?

2. What importance is there in how the general population perceives storm watches and warnings? For example, how did the population of New Orleans react to the warnings about Hurricane Katrina?

3. For the most part, when we look at climate change we are looking at atmospherically oriented change that occurs over long periods of time over large areas. There has been some division in the scientific community about whether we are going through a period of global warming or not. What are some reasons why society, especially in the U.S., has been more and more accepting of the view of global warming?
