An attitude of “denial” of the perils of climate change “must not prevail” if mankind is to successfully combat global warming, the Vatican’s Secretary of State warned Tuesday.

In his message on behalf of Pope Francis to participants in the U.N.’s COP24 climate meeting in Katowice, Poland, Cardinal Pietro Parolin said that information from the U.N.’s most recent climate change report is “even more worrying given that the current commitments made by States to mitigate and adapt to climate change are not sufficient to achieve the objectives set by the Paris Agreement.”

While “it is still possible to limit global warming,” Parolin said, “to do so will require a clear, forward-looking and strong political will to promote as quickly as possible the process of transitioning to a model of development that is free from those technologies and behaviours that influence the over-production of greenhouse gas emissions.”

What about greenhouse emissions from the church ?
