The Clergy Letter Project, originally formed to demonstrate that numerous members of the clergy embrace evolution and regard it as harmonious with their faith, is now also addressing the climate crisis. A new letter from the project entitled "The Climate Crisis: A Clergy Call to Action" recognizes the reality of anthropogenic climate change and pledges "to express our love for humanity and for all life on Earth by advocating for an immediate change in our behaviors that continue to threaten the health of the planet, its people, and their varied cultures." It is already endorsed by 753 members of the clergy in twelve countries, and new endorsers are welcome.
