Just as many of you have posted, there is no threat that the oceans will rise because of floating icebergs melting, even though this goes against common sense thinking by assuming the ocean will rise. One bit of information that I found interesting from http://www.howstuffworks.com/question473.htm is that if the temperatures warm up a little, then chunks of ice will break off of the frozen glaciers on landmasses and fall into the ocean. This will cause the oceans to rise.
This is a great lesson to share with students to get them to really think and draw conclusions for themselves about a current questionable hot topic.
