where is all this water supposed to come from?

[lacrew]

One gallon equals 0.1336806 cubic feet.

[KarlInOhio]

Antarctica has about 7 million cubic miles of ice. That’s 7.7 quintillion gallons.

[goseminoles]

Yall have too much time on your hands. :o)

[TexasCajun]

Good Question for Algore.

[dfwgator]

I’m still trying to figure out how many licks it takes to get to the center of a Tootsie Pop.

[bagman]

I think that a large fraction of the rise is supposeed to come from thermal expansion of seawater.

[ClearCase_guy]

Taking the exact opposite tack -- people have worked out a fairly simple plan to build a canal from the Mediterranean to the Quattara Depression (in Libya). Any rise in sea level (although, as you point out, any such rise seems unlikely), but any such rise which did occur could be easily sent out into the depression where it would quickly evaporate. Substantial hydro-electric power could be generated as well.

Basically, no sensible person should worry about any rise in sea levels. It ain't gonna happen.

[dblshot]

one acre foot equals 325851.428571 gallons. You do the math.

[dalereed]

Less than one if you can figure out how to measure it!

At a dollar a gallon 0bama and Algore could find it

Treat the sq miles of the oceans as the area of a circle and then use the volume of cylinder to raise the height of the oceans to any measurement you want.

I did this a few weeks ago. For instance, for the world oceans to rise 6 inches, it would take 216 Greenlands to completely melt.

[GeronL]

so apparently every ice cube, frost, snow, and glacier on Earth would have to melt?

[vamoose]

Don’t forget, as the oceans rise, even by 1 foot, the 140,000,000 sq miles of oceans will increase.

[SkyDancer]

How much explosives would it take to lower an island?

[HD1200]

Why bother? If the caps melt, the weight of the water will be spread over the whole ocean (9/10ths of the earth’s surface) instead of the caps. The caps will rebound from the weight removal while the cean floor will be more compressed from the weight addition. End result; no change in the height of the oceans.

PS: The glacial areas are STILL rebounding upwards after the loss of the weight of the last glacier that covered the area.

[SampleMan]

If you take the ice caps (non-floating) of Greenland and Antarctica, do the math on water having less volume than ice, assume no increase in atmospheric water. You come up with about 37 feet of ice that needs to melt off of the entire areas to increase the seas by 1 foot.

Now, if you look at Antarctica, you will find that most of the continent never gets anywhere close to 32 degrees. With that in mind, how does warming Antarctica from -5 to -4 or even -1, melt the ice cap?

[dps.inspect]

Presumably, if the sea level rises, that increases the water surface of the earth exposed to the sun. Q. If the sea level rises, will there necessarily be more evaporation of the sea surface? if so, then would there be more atmospheric moisture? if so, would the additional atmospheric moisture act to cool the surface of the planet? if so, would the arctics pile up ice again reducing the sea level to where it once was? if so, is the earth's climate self regulating? No I don't know earth sciences very well, but what would physics imply or even equate.

[scottteng]

The forgotten item in all these calculations is that most of the ice is floating on water displacing the same amount of water by weight as it weighs. Ice is less dense than water if it were not then the bottoms of lakes would freeze first killing al the fish. When ice melts the water level stays the same. Check it out with a brimful glass of ice water.

[pfflier]

Also remember Ice has more volume than water. So, as it melts, it will result in a lesser amount of liquid water by about 8%. (Mass density of ice is .92 g/ml vs 1 g/ml for water)
