It can be done:
[W]hen it comes to talking to evangelical audiences about climate change, [climate scientist and evangelical Christian Katharine] Hayhoe doesn’t emphasize the age of the Earth, simply because, she says, there’s no need. “When I talk to Christian audiences, I only show ice core data and other proxy data going back 6,000 years,” says Hayhoe, “because I believe that you can make an even stronger case, for the massive way in which humans have interfered with the natural system, by only looking at a shorter period of time.”
“In terms of addressing the climate issue,” says Hayhoe, “we don’t have time for everybody to get on the same page regarding the age of the universe.”
