John Shortridge writes: Re. "Pell-mell: what Australia's cardinal will really bring to the Vatican" (Friday). I have no views on Cardinal Pell in general. However, his view that on the subject of climate change the consensus of the overwhelming majority of qualified scientists is nothing but a new green paganism should concern us. At the height of some public discussion of creationism a few years ago I commented to a Catholic friend that it seemed to me (from a distance) that the Catholic Church didn't generally give too much credence to that sort of nonsense. His reply was "you have to remember that they got their fingers burned with Galileo". Cardinal Pell appears to have forgotten Galileo.
