"This handbook describes the five-step process for developing multivariate climate change scenarios taught by the Global Business Network (GBN) during a series of training workshops hosted by the National Park Service in 2010 and 2011. The authors created this guide as a reference for workshop participants who possess some familiarity with scenario planning. The process featured in this manual is not a definitive method for building climate change scenarios, since many valid methods exist to develop climate change scenarios. The technique presented here is just one effective and proven approach. "
