- The genesis of the essays contained in the text is explained thus on the websites of Nature and the Pontifical Academy of Sciences: “From 9-13 November 1998 an important workshop was held at the Pontifical Academy of Sciences. This workshop on the subject of Geosphere-Biosphere Interactions and Climate was concerned with those environmental and climatic changes which may pose a threat to human society during the course of the next century… This meeting of world experts at the Pontifical Academy of Sciences summarised our present-day knowledge about the subject and identified gaps in our understanding of how the earth’s climate is affected by greenhouse gases, deforestation, and the circulation of the oceans.”

“What air is for biological life, the Holy Spirit is for the spiritual life; and as there is air pollution, that poisons the environment and living things, there is also pollution of the heart and the spirit, that mortifies and poisons spiritual existence. In the same way that we should not be complacent about the poisons in the air — and for this reason ecological efforts are a priority today — we should also not be complacent about that which corrupts the spirit.
“But instead it seems that our minds and hearts are menaced by many pollutants that circulate in society today — the images, for example, that make pleasure a spectacle, violence that degrades men and women — and people seem to habituate themselves to this without any problem. It is said that this is freedom but it is just a failure to recognize all that which pollutes, poisons the soul, above all of the new generations, and ends up limiting freedom itself.
“The metaphor of the strong driving wind of Pentecost makes one think of how precious it is to breathe clean air, be it physical air [with our] lungs, or spiritual air — the healthy air of the spirit that is love — with our heart.” (Pope Benedict XVI, Homily on the Solemnity of Pentecost, 31 May 2009.
