Climate Speaker Directory

Are you looking for a climate speaker for your event?

You will find here a list of inspiring speakers who can provide expert insights into the various scientific, social or religious aspects of climate change.  On this page, you’ll find informed and skilled communicators who are enthusiastic about engaging with diverse groups about the urgency of climate change, and about real solutions to this crisis.  We have chosen these speakers because we know they are skilled at creating dynamic sessions, and because they represent a wide range of expert perspectives on real climate issues.

All speakers come to these events with the following CSCS principles:

-Trusted authorities who are trained in their area of expertise.
-Selected for their ability to communicate effectively.
-Respectful of individuals who disagree, and start from a position of listening when conversing with audiences.  
-Comfortable conversing with audiences from a variety of ethnic, socioeconomic, cultural, faith and political backgrounds.   
-Speak from an Anabaptist perspective, but do not assume that audiences come with the same Anabaptist or other faith perspectives.  

To arrange a speaker, email us at We can respond to specific events you’ve arranged, or help you set up a virtual event.  In the current pandemic context, we are offering speakers for virtual events only.  In the future, we will respond to requests for in-person events as we can. We provide honoraria for speakers, and do not charge for making speakers available, but welcome donations to CSCS to help cover costs.

Doug Kaufman, CSCS Director of Pastoral Ecology

Douglas Kaufman is Director of Pastoral Ecology at CSCS, and Co-pastor of Benton Mennonite Church, Goshen Indiana.  He has worked with his congregation and more broadly on ecological and sustainability issues for about 20 years, since learning that the river where they baptize sometimes has too much manure for safe contact.  That has led to ongoing volunteer water testing through Hoosier Riverwatch, and more recently to a Master’s of Theology in ecology from the University of Toronto.  His more recent research has focused on ritual and theological responses to the emotional barriers that keep people from engaging the climate crisis.  

“Our faith needs to be a resource to help us engage the reality of climate change, rather than a way to help keep us in some form of denial about it.”

Speaking Topics include

-How faith can help us move from soft forms of climate denial to engagement
-How hope can help us confront climate despair
-Also available for:
        +Sermons and Sunday School sessions for churches
