Mary Evelyn Tucker, a senior lecturer and senior research scholar at Yale University and a co-founder and co-director of its Forum on Religion and Ecology gave the keynote address for the “Sustaining hope in the face of climate change” gathering in Washington, D.C., May 1-2, sponsored by the Episcopal Church and the Church of Sweden. She suggested that the academy (and scientists in particular) and the church must both change their stances in the face of overwhelming evidence of climate change.
