It seems that the Pope would rather be the vicar of Al Gore instead of God...
I don’t think the Pope should be involving himself in something like this. If he wishes to tell the flock to do their best to be good citizens, I don’t have a problem with it. His views are important to his people. I don’t think he should try to drive public policy.
The information on this is just too spotty. There’s no consensus that the planet is doing anything other than just what it always has.
It’s unfortunate for him to have done this IMO.
