I just heard this morning that a The British Antarctic Survey discovered a huge piece of Wilkins Ice shelf in the Antartic is "hanging by a thread". Apparently it is 7 times the size of Manhattan!!!

I found a link to the press release by Britain's National Environment Research Council:

And another link to USA Today's story on it:

This is some rather disturbing news and big phat wake up call !! Interesting timing with EARTH HOUR being only 56 hours away!
