"People of faith are vital to the effort to combat the climate crisis and represent all walks of life," Gore said regarding Thursday's gathering at the Loews Vanderbilt Hotel in Nashville.

Gore spoke to members of 18 religious denominations at the gathering, ranging from Presbyterian leaders to Roman Catholic officials.
