The Mountain Social Ecological Observatory Network (MtnSEON) is a US National Science Foundationfunded Research Coordination Network that focuses on social-ecological systems (SES) science approaches to understanding the vulnerability, resilience, and sustainability of complex mountain landscapes. Papers from members of several MtnSEON working groups are presented in this Special Issue, with topics ranging from applying an SES conceptual approach to social-ecological observatories to dealing with the human aspects of predator-livestock interactions in the American West. All of these articles portray varying degrees of integration of social and ecological sciences and methodologies in order to better address both complex and "wicked" problems inherent to many coupled natural and human systems. The diversity of approaches presented here reflect the different project histories, disciplines being integrated, fields of expertise, and nature of the environmental problems and issues being addressed.

This article uses interview data with people who were once skeptical about climate change but have come to accept climate science to assess the factors that contribute to their shifts in perspectives. Our findings show two trajectories of change for skeptics, depending on the nature of their skepticism. For those who move from actively denying climate change, shifting beliefs about climate change occur via a profound need to reconcile what emerges as cognitive dissonance due to challenges to their religious identities. For skeptics who move from being unsure about climate change, moving to accept climate science happens through either encountering new information from a trusted source or personally observing the effects of climate change. This extends existing scholarship on the factors that contribute to changing minds on climate change.
