Eric Chivian, director of the Center for Health and the Global Environment at Harvard Medical School agreed, saying, "scientists and evangelicals have discovered that we share a deeply felt common concern and sense of urgency about threats to life on Earth, and that we must speak with one voice to protect it."
In February 2006, 86 evangelical leaders signed a statement to fight global warming, saying human-induced climate change is real, its consequences will hit the poor the hardest, and Christian moral convictions demand urgent response to the problem.
They contended that governments, businesses, churches, and individuals all have a role to play. Signatories included presidents of evangelical colleges, aid groups, and churches.
The National Association of Evangelicals did not sign the statement.
Speakers at the Wednesday announcement will include Pastor Joel Hunter, who refused to take the leadership of Christian Coalition of America because the organization wouldn't let him expand its agenda to include the environment and poverty.
Others are Harvard biologist and two-time Pulitzer prize winner Edward O. Wilson, and NASA scientist James E. Hansen who came under fire from the White House after a December 2005 lecture in which he called for urgent reductions in greenhouse gas emissions to slow global warming.
