"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."
