August 8, 2007
Permafrost--the perpetually frozen foundation of the north--isn't so permanent anymore, and scientists are scrambling to understand the pros and cons when terra firma goes soft. Permafrost serves like a platform underneath vast expanses of northern forests and wetlands that are rooted, literally, in melting permafrost in many northern ecosystems.
