So cardinal Pell, is speaking out against human caused global warming. In all honesty his opinion here matters far less then it does in his normal field of preaching morality.
And as usual the Sydney Morning Herald has chosen to not allow comments on this story. Probably for fear that the "good" cardinal would be well and truly roasted in them.
For what my opinion on the subject matters, Which is very little, I have been a skeptic for a very long time. However I think that the position of climate change skeptic is getting more an more tenuous and unscientific with every passing day. And the reality that there is hard scientific evidence for climate change is now well and truly beyond reasonable doubt.
