Regarding ice melts and raised ocean levels, here are some interesting things to think about.
When water freezes it takes up more volume.
Temperature 20 C, density = 0.998207 g/cm^3
Temperature 4 C, density = 0.999975
Temperature 0 C, density = 0.9998425
Temperature -0.1 C, density = 0.9150
When frozen, water takes up about 9% more volume than in liquid form. Less dense means more volume as the above statement defines. This is also easily
proven if you freeze a can of soda, it explodes.
Now, another interesting fact. Icebergs are 90% under water. So if an iceberg melts you aren't introducing 10% more volume into the ocean (the part
that's sticking out) you are adding a significantly lower percentage due to the fact the 90% is now taking up 9% less volume than when frozen.
Of course any ice that melts on land would add volume to the oceans.
If you have studied google maps or even read threads on ATS of ancient artifacts under water it begs the question. Would the melting of the ice caps
actually decrease the ocean levels? Would all of the ice at the poles actually be artificially propping up the ocean levels we see currently due to
the 9% increase in volume of all the ice on a global scale?
I don't have the answers to these questions but it sure is fascinating to wrap your mind around.
