Scientists say pope may be the key player on climate change

USA Today - Scientists weary after years of often vicious opposition by doubters of their climate-change findings see this year as crucial to the planet's future because of a religious document expected from Pope Francis on Thursday.

"Many people have this rosy view that there's this knowledge deficit, and that if we just provided more information or if we explain the science better or if we package it better, maybe with colored graphics, or write another scientific paper, that will be the one to convince (doubters)," said climate scientist Katharine Hayhoe of Texas Tech University.

"But the reality is it's not a scientific issue (any longer). It is an ideological issue. We have to appeal to people based on values. Not just on data and facts. And for me as a scientist to say that is very unusual," Hayhoe said. "So from that perspective the pope is a very effective messenger."
