Drought Early Warning: Theory and Practice, a book written by Chris Funk and Shrad Shukla, provides a comprehensive overview of drought-related scientific research, describes the available tools and techniques, and informs readers on how to use these tools and techniques to effectively identify, predict and communicate potential drought-related disasters. Throughout the book, the authors incorporate "climate change" as a pragmatic component of effective drought early warning, dealing explicitly with climate non-stationarity, increased climate variability, and the impacts of air temperature extremes. This comprehensive resource simultaneously addresses the physical, social and information management aspects of drought early warning. The book is available for purchase here.

A blog about climate science and making a difference.
