A new study from Boston College reveals that an overwhelming 90% of Christian leaders in the United States, spanning denominations from Catholics to Evangelicals, believe in human-caused climate change. Published in the Proceedings of the National Academy of Sciences, the research highlights a communication gap that could be critical in mobilizing faith-based climate action. Despite some prominent Evangelical figures denying climate change facts, a survey of 1,600 U.S. religious leaders revealed that nearly 90% of Christian leaders acknowledge anthropogenic climate change to some extent. A second of nearly 1,000 American Christians across major denominations, respondents significantly underestimated how many religious leaders believe in human-caused climate change. In a follow-up experiment, another group of nearly 1,000 Christians—half of whom were informed that 90% of Christian leaders accept man-made climate change—showed significant shifts in perception.
