Section 1: Is Global Warming Making Hurricanes Worse?
1. What makes a hurricanes “worse,” in your opinion? (more hurricanes, stronger hurricanes, more damage from
hurricanes)?
2. How would warming ocean waters affect a hurricane?
3. Where do hurricanes get their energy from?
4. What are hurricanes called everywhere else in the world?
5. What are the three main factors that can affect the formation of a hurricane/tropical cyclone?
