Casey, the main character in Brian Adams’ novel Love in the Time of Climate Change, has obsessive-compulsive disorder. A community college professor, he frets over global warming, proper recycling protocols and winning over one of his female students — and that’s just the tip of the iceberg. Helplessly drawn into a series of increasingly awkward situations — think field trips gone awry and shoplifting at Walmart — Casey delivers equal parts humor and eco-friendly musings. Within these missteps and wayward wanderings lies a message about the state of the planet that has readers learning while laughing.
