    Okay peoples so I had a thought and I wanted to share it okay so tell me what u think.

    So some peoples say that the earth is getting warming and okay that as that happens the icebergs will melt and that means the oceans will rise.

    But water is one of the rare chemicals that possess the property of greater density in liquid phase, which is why ice floats in a glass of water, and in point, why icebergs float rather than rest on the ocean floor. Incidentally, the fact that water, crucial for life on this earth, possesses this property is fascinating to me, coz if it dint then every winter many freshwater ecosystems would be seriously damaged, with the subsequent cascade of consequences elsewhere in the environment.

    Now part of icebergs is seen above the water but most of dem is below the surface, where they displace more volume as a solid then they would as a liquid.

    So my questions peoples is that if icebergs melt, wouldn't that result in a net decrease in the volume of the ocean and concurrently, in a decrease in ocean sea levels?

    I'm not debating global warming here, at all. I just had this thought about ice and water and all and was curious what the actual explanation was.

    Is the focus more on the runoff from glaciers? Or does the fact that at least a portion of an iceberg protrudes above the surface offset the net decrease in volume when one melts? Whats the deal, yo?

    the answer is: Ruff. That's the way your mother likes it.

    Ok seriously I have no clue. Paging Llamatron!

    This is D_C's thing also, and I'm guessing he or someone else will have a ready explanation that makes perfect sense.

    I just can't come up with it on my own.

    true. Would it have something to do with density vs. mass?

    EDIT: Yeah wikianswers. Don't know if it's true, but sounds pretty damn smart.

    Melting iceburgs wont effect the water level. It's iceCAPS. The stuff that's on land.

    The whole north pole could melt away and it wouldn't make a difference to the sea level, for the exact reasons you've stated; that water is already in the ocean. It's just in ice form.

    It's the south pole (and all the other above-land ice) you have to worry about.

    Yeah, after reading what I quoted more thoroughly, that seems to coincide with what you are saying.

    Huh.

    Yeah, that was a lot easier to explain that I thought it would be. Oh, well, here's hoping my place in Atlanta becomes beachfront property!

    Man there is a certain picture of certain polar bears with a certain sign asking for the help of a certain ex-vice president that I REALLY wish I could post here, it's so appropriate...

    Yeah, its if the antarctic and greenland icecaps melt that there could be trouble.

    I would more worried about their effect on ocean current flow than the rise in ocean levels.

    If you think icebergs melting due to global warming is serious, then that's nothing compared to the possibility that the polar ice caps melt... if that happens, the oceans are going to swell with this new surge of water, and all areas vulnerable to flooding will be submerged; only lands high above sea level will be left, and then... well, I'll leave that up to your imagination.

    That is assuming that global warming is an actual issue.

    The oceans will rise 1-3 feet above current sea level of coastal regions tops if the ice caps melt entirely, from what I've heard (I think that estimate was from the UN's climate change council). Though we won't really have to worry about that, as the current climate change thing says that global temperatures have cooled (they peaked in 1998, and have been decreasing since) due to all the ice entering the ocean due to global warming.

    That's right: the temperature's getting colder because of global warming.
