Pope Francis outlined his views on climate change in two encyclicals, Laudato Si’ (2015) and Laudate Deum (2023). Concisely, the Pope fears that the world in which we live is collapsing and may be nearing the breaking point because of climate change. In fact, the Pope announced in his encyclicals that there is a “global climate crisis.”

In the essay Pope Francis’ Climate Crusade or the erosion of faith in God chemist and theologian Jaap C. Hanekamp and statistician and meteorologist William M. Briggs reflect on both encyclicals, though they do not assess the scientific information on climate change as such. Instead, they examine the Pope’s use and understanding of models, and delve deeper into the overarching philosophy that sustains both encyclicals. They conclude that the Pope, carelessly in their view, embraces scientism, and not science, which inadvertently weakens his position, and those that follow his scientistic prescriptions.

Scientism is the ideology that science alone is deemed capable of elucidating and resolving all genuine human problems, and that all human affairs can be reduced to science. Accordingly, scientism is the effort to expand science to all other fields of human affairs, even theology, and to usurp them in a reductionist fashion.

Hanekamp and Briggs conclude that the climate scientism Pope Francis peddles stands diametrically opposed to the Christian worldview. “Scientism of any stripe is incommensurable with not only the Christian faith but also with science.”

ABOUT CLINTEL
The Climate Intelligence foundation (Clintel) was founded in 2019 by emeritus professor of geophysics Guus Berkhout and science journalist Marcel Crok. Clintel’s main objective is to generate knowledge and understanding of the causes and effects of climate change, as well as the effects of climate policy. Clintel published the World Climate Declaration, which has now been signed by more than 1900 scientists and experts. Its central message is “there is no climate emergency”. In 2023 Clintel published the book The Frozen Climate Views of the IPCC, in which it documented serious errors and biases in the latest IPCC report.
