Here's a surprise! The Earth is changing! Just like it's done the past Billions of years! Who knows, maybe Ohio will be the new polar ice cap?

Try observing the change in water level in a glass of water with a frozen ice and then after it melts.

Of course the earth is an unstable system and changes are natural, same as tsunamies which kill 300,000 people in SE Asia are natural. Doesn't mean we should ignore the dangers of change does it?

What alot of you cretins overlook is that the south pole and the ice on greenland is not floating in water but it is resting on landmass.
gg no re

i learned that iceland is really green and greenland is really icey on mighty ducks quack quack quack quack

Scientists previously lacked knowledge of changes in terrestrial storage of water. Surveying of water retention by soil absorption and by reservoirs outright ("impoundment") at just under the volume of Lake Superior agreed with a dam-building peak in the 1930s-1970s timespan. Such impoundment masked tens of millimetres of sea level rise in that span. ( Impact of Artificial Reservoir Water Impoundment on Global Sea Level. http://www.sciencemag.org/cgi/content/full/320/5873/212?rss=1. B. F. Chao,* Y. H. Wu, Y. S. Li). Just need to build more dams, problem solved ...err masked.

Polar ice caps are generally used to refer to any ice in a polar region, though ice caps specifically refer to ice over land (glaciers).
By Archimedes's principle, we know that any ice floating in ocean water would not raise the sea level at all. However, the melting of ice caps / glaciers WILL cause significant rises in sea level; you cannot calculate sea rise linearly (with your little 2mm x 100) because ice reflects sunlight much better than water does, so as more and more ice melts, there is more water -> water soaks up more heat -> ice melts even faster. Vicious cycle of doom.

So, lets focus now and forget the future, eh?

I really expected better from teamliquid.
So much armchair science going on. Your arrogance astounds me. How could you possibly think something as vastly complex as the earth's climate can be solved with one short sentence?
Actually... well done to many of you, you've exposed the myth that is global warming. It's that easy. Seriously. All the scientists (amongst which there is a greater consensus than any other field of science) are wrong. There is nothing to worry about, we can all go back to business as usual. Seriously though, do you actually think nobody has considered the immensely basic principal that the melting of suspended ice does not increase the water level in and of itself?
I'm reminded of an xkcd comic:
Oh and here is most of the climate change denier's arguments refuted in one go.
+ Show Spoiler + To quote xkcd again:
What is more likely -- that you have uncovered fundamental flaws in this field that nobody has ever thought about, or that you need to read a little more? Hint: It's the one that involves doing less work and sticking your head in the sand.

That is an awesome picture. I think I'll use that in every global warming argument i ever enter

Your point is a good one, we must be mindful of allowing ourselves to become trapped within our axioms. The reason, I feel, that such an idea survived for so long, was because it was itself axiomatic and simply accepted as fact rather than extensively researched.
Scientists in the field know how much resistance there is to the widespread acceptance of their theory. One feels, upon reading such reports as those given to congress last year, that they have gone above and beyond what would generally be required.

LOL thats what I get for mixing mass quantities of marijuana with simple 2nd grade math skills. Sigh.

Another thing people in this thread seem to be forgetting (or simply never learnt) is that a materials mean temperature doesn't begin to change significantly until a decent proportion of the material has changed state. Because of this mean surface temperatures at the polar ice caps won't change significantly. Locally both the ice and water may be 0 degrees C. However once the ratio of ice to water reduces you will begin to see an acceleration in temperature change, (because of the nature of heat transfer. with a lower surface area the ability of energy to transfer between the ice and water will reduce.).
This is also without taking into account the fact that ice will reflect a lot of radiation away while water will absorb more of it, this also causes the energy going into the system to increase and can occur without significant temperature change (because of what I explained in my first paragraph). This process can also cause a local decrease in air temperature because a lower proportion of energy is being radiated back through the atmosphere.(due to increased levels of liquid water)
Most people don't seem to look at the system as a whole. They will either look solely at atmospheric temps or surface temps without understanding how they're interelated.
Reduction in polar ice caps shows that the enthalpy of the system is increasing. This is essentially acting as a buffer to temperature change. The more they reduce the greater the acceleration of temperature change will be because energy will no longer be able to stored by merely a substance changing state.
