"PARIS — The cold hard numbers of science haven't spurred the world to curb runaway global warming. So as climate negotiators struggle in Paris, some scientists who appealed to the rational brain are enlisting what many would consider a higher power: the majesty of faith.

It's not God versus science, but followers of God and science together trying to save humanity and the planet, they say.

Physicist John Schellnhuber, founder of the Potsdam Institute for Climate Impact Research in Germany, said he has been coming to these international talks for 11 years and essentially seen negotiators throw up their hands and say 'sorry guys we tried our best.' And no one protested. But this time, with the power of Pope Francis' encyclical earlier this year calling global warming a moral issue and an even more energized interfaith community, Schellnhuber feels the world's faithful are watching and will hold world leaders accountable.

'They know they will be measured against the encyclical,' Schellnhuber, a member of the Vatican's Pontifical Academy of Sciences, said Saturday at a Catholic Church event. Ever the scientist, Schellnhuber said on Saturday he hadn't seen any evidence yet during the first week of negotiations that this will happen, but he has faith it will."
