KerPlunk! and Planet Earth

This chapter provides an overview of the book's main themes, which focus on the potential human costs of climate change. The book attempts to illustrate the impact of climate change based on the assumption that temperatures will rise by 2° C by the end of the twenty-first century. It argues that the most important barrier to a sensible and determined response to climate change is a lack of public understanding about the ways in which people's lives will be affected.
