Skip to comments.How many gallons of water needed to raise the Seas?
Posted on 01/18/2010 2:47:33 PM PST by Former MSM Viewer
There are 140,000,000 sq miles of oceans.
I want to calculate how many acre/feet or in this case sq mile/ft of water would be needed to raise the level of the sea 1'.
One acre/foot is the amount of water it takes to cover 1 acre 1' deep, which is about 323,000 gallons.
There are 640 acres in 1 sq mile.
To raise 1 sq mile 1', it would take 323,000 X 640= 206,720,000 gallons.
There are approximately 140 million sq miles of ocean on our Blue planet.
To raise 140 million sq miles 1' it would take 140,000,000 X 206,720,000=
This is where I need some mathematical help.
What is the volume in cu ft or how many Mt Everests = almost 29 quadrillion gallons of water.
Remember, 29 qualdrillion gallons will only raise the seas 1'. The Global Warming crowd says the seas will rise over 6' if we dont pay up...
One gallon equals 0.1336806 cubic feet.
Antarctica has about 7 million cubic miles of ice. That’s 7.7 quintillion gallons.
Yall have too much time on your hands. :o)
Good Question for Algore.
I think I’ve done these calculations before, based on what I could find for volume of land ice...and the 6 ft number is true, if it all melts...but alot of libs still live in Florida without fear.
I’m still trying to figure out how many licks it takes to get to the center of a Tootsie Pop.
I think that a large fraction of the rise is supposeed to come from thermal expansion of seawater.
Basically, no sensible person should worry about any rise in sea levels. It ain't gonna happen.
one acre foot equals 325851.428571 gallons. You do the math.
Less than one if you can figure out how to measure it!
****** “ where is all this water supposed to come from? “ *****
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.
so apparently every ice cube, frost, snow, and glacier on Earth would have to melt?
Don’t forget, as the oceans rise, even by 1 foot, the 140,000,000 sq miles of oceans will increase.
but, but, but.... what about Algore peeing in the ocean?
Psssst, he is working on that - Global Flooding
He got away with Global Warming, meeeedia are already sharpening their pennnnns and another Nobel is aroud the cornerrrr,
How much explosives would it take to lower an island?
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.
Al Gore doesn’t answer questions—because he knows he can’t defend his lying position.
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?
Great info! I never thought about this aspect before.
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.
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)
Ask the makers of the movie Waterworld.
The sea level would not increase instantly. So they would have a chance to move inland. As well as everyone else that lives near the ocean.
One simple fact that the global warming crowd ignores, Ices expands and when it warms up it’s volume decreases.
If all the ice in the world melted the sea level would go down not up. Not to mention the higher temperatures would cause more water to be vaporized.
It is just bad science from someone that failed to get a degree in theology.
Gallons? Too easy. How about teaspoons? ;’)
I posed this to my grandson, who has his Masters in Mechanical Engineering from the University of Michigan. He offers the following:
Let me begin by saying that I am using the following rough assumptions.
http://hypertextbook.com/facts/2000/HannaBerenblit.shtml has a reasonable estimate of the volume of polar ice caps (33 million cubic kilometers)
Ice is about 9% less dense than water (source: wikipedia)
So let’s start.
It was previously computed that 29 quadrillion gallons of water would raise sea level 1 foot. Cool. That’ll never happen, I mean that’s a ton of water right?
Let’s see what the Ice Caps have to say about that.
As stated as an assumption, we will assume 33 million kilometers of frozen ice.
converting that to cubic meters of ice, we get 3.3*10^16 cubic meters of ice.
Now we melt that to WATER, which is 9% less dense
that leaves us with 3.003*10^16 cubic meters of WATER.
Converting cubic meters to gallons (264.1721 gal/cubic meter)
gives us 7.933*10^18 gallons of water.
Divide that by the amount of water to raise sea level 1’ (29 quadrillion) gives us
7.933*10^16 / 2.9*10^16 = 273.55476
or about 274’ of raised sea level.
now, take three case
The Ice caps are all above sea level already, in which case ALL of this water would raise the sea level (answer = 274 feet)
The Ice caps are like icebergs, with 90% underwater, already (answer = 27.4 feet)
Most likely, a lot but not all ice is above water, call it 50/50 (137 feet)
Case 1 and Case 3 probably drown all of Miami, Manhattan, New Orleans, Netherlands, most of the Caribbean, never mind what it does to the climate and weather.
Case 2 still destroys New Orleans, probably the Netherlands, and probably seriously hurts Manhattan and miami. If nothing else it is going to mess with the weather to have all that extra water in places like Mexico and Africa, and Southeast Asia.
Oh yeah Southeast Asia probably gets hit pretty hard by Case 1 and Case 3 as well. I wonder what all that water does to the deserts of the Middle east.
Anyway there you go.

Your numbers and the original poster’s numbers are all we need to know to come to the conclusion that there’s nothing humans could possibly do to create the disaster that the liberals fear, even if we all tried our best to bring it about.
The earth is simply too big and we humans are too miniscule a part to be a factor in that way.
But if it evaporated we would quickly run out of water!
Al Gore flunked out of divinity school. I suspect he can't balance his checkbook without removing his shoes & socks, let alone do simple mathematical calculations to figure the rise in sea levels.
