From an Expert on Economics To an Expert on Global Warming

Pope Francis will meet with some of the world's oil executives next week, likely to give them another moral nudge to clean up their act on global warming.
Climate change policy and science experts are cautiously hopeful but aren't expecting any miracles or even noticeable changes. 

But lighting the witch on fire will cause carbon emissions! What now?

 The conference will be a follow-up to the pope's encyclical three years ago calling on people to save the planet from climate change and other environmental ills, Vatican spokesman Greg Burke confirmed Friday. Cardinal Peter Turkson, who spearheaded the encyclical, set up the June 8-9 conference with the executives. The pope himself will speak to the leaders on the second day of the summit, organized with the University of Notre Dame, Burke said. 

 Oil companies have talked about fighting climate change, but they haven't done much beyond talk, said MIT management professor John Sterman.
The pope offers "moral persuasion," but if it is just a photo opportunity for oil executives to show off "it doesn't mean anything and in fact it's just PR to help oil companies burnish up their image while they continue to delay actions," Sterman said


Dana Fisher, a sociologist who studies environmentalism at the University of Maryland, said the pope is cementing his leadership on climate.
"He certainly is trying to lead for the planet and lord knows we need it," she said. 

Hurray! Leading for the planet. When he gets done, mabe he could lead the Catholic Church!
