In this lesson students will explore hurricane frequency and intensity, along with the correlation to global warming. In order for a hurricane to grow, warm water is an absolute necessity. So, if the Earth continues to warm, the students will attempt to answer the question, "What does it mean for hurricanes and their intensity?" The students will look at past hurricane data by researching the intensity and frequency of hurricanes using the Live Access Server and several internet sites found in the "Lessons Link" section. Detailed procedure and materials, vocabulary linked to an on-line glossary, and teacher notes are provided. Educational levels: High school
