Earth Almanac: Nature’s Calendar for Year-Round Discovery

By Ken Keffer

After writing a number of books focused on inspiring kids and families to get outside and appreciate nature, I shifted to adult audiences with my new book Earth Almanac: Nature’s Calendar for Year-Round Discovery.

The book presents the greatest hits of North American nature! Structured around phenology, the day-by-day descriptions offer insight into activities and connections throughout the natural world. Beginning with the Winter Solstice in December, Earth Almanac highlights a wide range of natural history, including mammals, birds, fish, reptiles, insects, intertidal and marine life, trees, plants, fungi, weather phenomenon, geology, astronomy, notable environmental activists, and more, and reveals the ebb and flow of nature across the planet. Each season features more than 90 entries, and sidebars throughout provide calls to environmental action, citizen science opportunities, and details on special dates or holidays. The book can be enjoyed one day, month, or season at a time—dip in and out as you observe the world around you. Engaging and accessible, Earth Almanac inspires readers to learn about and appreciate the natural world and to get outside and explore it.
