Looks like Global Warming to me...

Cardinal Pell disagrees with the Vatican study on Global Warming...
.
[Just because the Vatican publishes a study doesn't mean the results become an article of faith BTW.]
.
This weekend I was hosted to a special dinner at a friend's house and somehow the conversation strayed off onto right-wing nuts and Sarah Palin and global warming - favorite topics I tend to bring up when there is a lull in the conversation.  My host asked, "How can these idiots say there is no global warming?"
.
I answered, "I don't know."
.
I went on to say I think there really is global warming but I'm not sure it is all man made, nor do I think man has the capability to do much about it.  I personally think it is part of the earth's natural cycle, like women and their hot flashes - the planet is going through a natural cycle of warming, and next it will probably begin cooling and ask for a sweater.  The concept is easy to grasp for the terminally subjective, since it has been a very cold spring so far this year.
.
Anyway - I find that I agree with Cardinal Pell on this one.

Sydney's Cardinal George Pell said the causes of climate change remain "unclear", even as a Vatican-appointed panel of scientists warned about the need to mitigate man-made global warning, reports the Sydney Morning Herald.
.
"Climate change is real," he told the newspaper. "The causes are unclear, and our ability to influence climate change [is] even less certain," he said. - Source

Yep!  Mother Nature's just having a hot flash.
