The US denial propagandists, funded by conventional energy companies and a foundation controlled by conservative petrochemical billionaire Charles Koch, will try to persuade the Vatican that global warming does not exist. They have chosen this week because the Pontifical Academy of Sciences is holding a summit tomorrow called "Protect the Earth, Dignify Humanity: The Moral Dimensions of Climate Change and Sustainable Development."

As well as secular leaders, representatives from all the world's major religions will attend the meeting. Speakers will include UN secretary-general Ban Ki-moon and Columbia University economist and author of The Age of Sustainable Development Jeffrey Sachs.

From the conference website:

Organised by the Pontifical Academy of Sciences, the Pontifical Academy of Social Sciences, SDSN and Religions for Peace, the goal of this summit is to raise awareness and build a consensus that the values of sustainable development cohere with values of the leading religious traditions, with a special focus on the most vulnerable; to elevate the debate on the moral dimensions of protecting the environment in advance of the papal encyclical; and to help build a global movement across all religions for sustainable development and climate change throughout 2015 and beyond.
