Interestingly enough I read two articles a/b the potential collapse of an ice sheet in Antarctica the other day. The one on Fox news said it might collapse and this was GW rearing it's ugly head. The other was much more scientific and said that Antarctica is experiencing rapid ice/snow growth and will be on track for a record year even before winter starts there.

And I still think everyone should at least try to read this:
