The article does suggest that those bears are "trapped"...
For God's sake the bears can easily swim 100 miles. They look incredibly healthy. BTW they like to stalk and eat humans.
"They cling precariously to the top of what is left of the ice floe, their fragile grip the perfect symbol of the tragedy of global warming. ...the pair of polar bears look stranded on chunks of broken ice."
Gag me with a spoon. (I figure the 6th grade vernacular fits with this sentence.)
The seals need a better press agent!
