[T]here is a strong, credible body of evidence, based on multiple lines of research, documenting that climate is changing and that these changes are in large part caused by human activities. While much remains to be learned, the core phenomenon, scientific questions, and hypotheses have been examined thoroughly and have stood firm in the face of serious scientific debate and careful evaluation of alternative explanations. * * * Some scientific conclusions or theories have been so thoroughly examined and tested, and supported by so many independent observations and results, that their likelihood of subsequently being found to be wrong is vanishingly small. Such conclusions and theories are then regarded as settled facts. This is the case for the conclusions that the Earth system is warming and that much of this warming is very likely due to human activities. 
A liberal critic might contend that I have now engaged in some fairly obtuse hair-splitting. By suggesting that the Holy Father’s criticisms are directed only at a fairly extreme ideological position, it may seem that I am illegitimately minimizing the impact of his message. And my interpretation may just seem implausible, given that the Holy Father is clearly criticizing attitudes that he regards as both pervasive and problematic in the world today. Hardened libertarians are a fairly rare breed, and they have had minimal success in their efforts to establish a largely-unregulated free market economy. It might seem strange for the pope to show such intense concern over a minority view.
In an interview with the editorial board of the Pittsburgh Tribune-Review on March 25, 2008, Hillary Clinton commented on Obama's attendance at Trinity United Church of Christ, stating, "You don't choose your family, but you choose what church you want to attend." Later the same day, during a press conference, Clinton spoke on her personal preference in a pastor: "I think given all we have heard and seen, [Wright] would not have been my pastor." A spokesperson for the Obama campaign asserted that Clinton's comments were part of a "transparent effort to distract attention away from the story she made up about dodging sniper fire in Bosnia" the prior week.  Weeks later during the Pennsylvania debate in Philadelphia , Clinton said, "For Pastor Wright to have given his first sermon after 9/11 and to have blamed the United States for the attack, which happened in my city of New York, would have been just intolerable for me."
