The "Algores" of the world will be telling us that we are doomed, sea levels will rise, people will die dogs & cats will be living together in sin! We're doomed! Big whoop! So an iceberg the size of delaware broke off. About the only impact it will have is all the nut job photo hunters wanting to go take a photo of it, screwing up the sea lanes when it reaches a more moderate temperature zone, and, getting to close to it as chunks the size of buildings fall off and smack their boats. Stuff like this has been going on since the ice age, it's just that "humans" are here to witness it.
