Climate Church, Climate World contends that climate change is the greatest moral challenge humanity has ever faced. Hunger, refugees, poverty, inequality, deadly viruses, war—climate change multiplies all forms of global social injustice. Environmental advocate Rev. Jim Antal calls on the church to meet this moral challenge, to embrace a new vocation so that future generations might live in harmony with God’s creation. After illuminating how human beings are responsible for the dangers our planet now faces, Antal proposes how people of faith can embrace new approaches to worship, preaching, witnessing, and other spiritual practices that honor creation and cultivate hope.
