The Arctic Ocean has a real possibility of becoming ice free for the first time since the last ice age due to rising global temperatures. If oceanic ice continues to melt, how long will continental ice stored on Greenland and Antarctica last before it melts too? Melting ocean ice will not cause a rise in sea levels but melting continental ice will. What would that mean for low lying areas like Louisiana? It would certainly not be pretty.
