The National Catholic Rural Life Conference, headquartered in Des Moines, Iowa, has revised their Study Guide, Global Climate Change: A Catholic Reponse. It's available at the NCRLC Web site.
The Guide uses a reflection/action methodology called Shared Christian Praxis. The process has five progressive movements, beginning with identifying where people are in their life experiences, then engaging them in critical reflection on their experiences and relating those experiences to the Story and Vision of our Catholic faith. This process concludes with outlining the dimensions for future actions -- by an individual, a group, or an entire community. The end result is meant not only to change attitudes but to change behaviors on behalf of solidarity with the world and with God's creation.
