Why might a rise in the earth's temperature cause oceans to rise?

Question

It has something to do with isostasy, i think.

Answer 1

polar ice caps melt, hence more water, higher levels

Answer 2

All of the water sequestered in the form of ice at the poles will melt and raise the ocean levels.

Answer 3

Cause the ice caps at the poles melts.

Answer 4

because a rise in temperature means melting the polar ice caps. and that water then cycles south and other places into the oceans.

therefore causing them to rise!

Answer 5

Because the climate models using computer software cannot ever completely account for everything happening in nature.

For every action there is an equal and opposite reaction. What some scientists who are studying the sea levels have found is that there is more evaporation taking place that was not accounted for in the computer models that predicted AGW would cause the seas to rise. Also, glaciers that are melting in one part are expanding in another currently. If a glacier is not on land, its water displacement has been for all intents and purposes been nullified. This is very simplistic....mind you.

Fill a glass half full of water and the rest with ice and when the ice melts the glass has not spilled over. This goes for glaciers as well.

I could go on with other items like this all relating to just one aspect of climate research. The point is that even scientists that believe in global warming are constantly scratching their heads as to why climate models have such a wide variance or why they don't act like nature.

I think that we shouldn't necessarily accuse the scientists who often only look at one aspect of climate research of being stupid or wrong, but that maybe no one can clearly see the whole picture.

You have so many variables Solar Flares, Earth's rotation, Plate Tectonics, Volcanic activity on land and at sea etc....etc.... We cannot clearly see how it all fits together or how one will react with another force applied.

I think scientists need to constantly observe the earth before trying to predict a catastrophe based soley on computer modelling.

Answer 6

because it causes ice that's on land to melt and flow into the oceans.
