A couple of days ago I heard on the radio, not science, that the ocean levels have not changed much over the last 20 years.
How much ice melt does it take to raise the ocean one inch?
I suggest that you look at the Salton Sea, located in the southern California desert. It is the largest lake in the state, and is fed almost entirely from agricultural runoff.
-21 here in the heat island of Fairbanks. -42 elsewhere. Real cold due Friday, maybe -55. Be sure to keep us posted on ice loss.
I've also heard that moving ocean water to the Salton Sea would actually decrease the salinity of the Salton Sea. True?
There are about 6*10^17 square inches of ocean on the surface on the earth. There are about 2.5*10^14 cubic inches in a cubic mile. When you divide the two, you find that there are about 2400 cubic miles per inch of ocean depth. At 50 cubic miles of melting per year (which I don't believe) it would take 48 years to raise the ocean an inch.
Thanks for the ping. Other reports indicate that amount of ice is increasing.
The basin has dried out and refilled many times, and has a much larger capacity than its current content. However, I was really pointing it out as a “recently” filled saline lake.
Another major example is the Mediterranean Sea, which has evaporated (fully or partly) several times over the ages, due to the intermittent closure of the Strait of Gibraltar. It still loses more water by evaporation than it receives from its watershed, with the difference made up from the Atlantic through Gibraltar. Also, Israel is considering tapping the Mediterranean to replenish the Dead Sea, which is losing volume rapidly due to diversion of the Jordan River.

Something else the chicken littles fail to factor in is that rising rainfall (or rising oceans which contribute to the same) does not translate into equal levels of moisture retention in bodies of water.
If this were not so, much of the Laurel Hill region around Pittsbugh would be underwater most of the year. We have generous amounts of rain stored in the flora of this region. I'm not a botanist, but we bought a house here for a bargain price because it was getting basement seepage. A couple of low-tech modifications (suggested by an expert which I paid $300 before finalizing the house deal) removed the problem:

If they really were shrinking at 48 cubic miles per year, it would take over 1,600 years for them to lose one percent of the Greenland + Antarctic estimated sum of about 7.8 million cubic miles.
In one of the report’s most worrisome findings, the agency estimates that in light of recent ice sheet melting, global sea level rise could be as much as four feet by 2100. The IPCC had projected a sea level rise of no more than 1.5 feet by that time, but satellite data over the past two years show the world’s major ice sheets are melting much more rapidly than previously thought. The Antarctic and Greenland ice sheets are now losing an average of 48 cubic miles of ice a year, equivalent to twice the amount of ice that exists in the Alps.
2001 estimate - CBS News
Antarctica contains about 7.2 million cubic miles of ice, about 84 percent of all the glacial ice on Earth, according to the USGS.

East Antarctic Ice Sheet Gains Mass and Slows Sea Level Rise, Study Finds
From 1992 to 2003, Curt Davis, MU professor of electrical and computer engineering, and his team of researchers observed 7.1 million kilometers of the ice sheet, using satellites to measure changes in elevation. They discovered that the ice sheet’s interior was gaining mass by about 45 billion tons per year, which was enough to slow sea level rise by .12 millimeters per year. The interior of the ice sheet is the only large terrestrial ice body that is likely gaining mass rather than losing it, Davis said.
Eco-Economy Indicators, 2005: Ice is Allegedly Melting Everywhere
A conservative estimate of annual ice loss from Greenland is 50 cubic kilometers (12 cubic miles) per year, enough water to raise the global sea level by 0.13 millimeters a year.

Omg...the Greenie Sea Level Rising Wackos ain’t gonna like you. Imagine...just siphon the excess sea water into huge low lying areas...nope, they ain’t gonna like you at all.
Thanks for your very informed reply.
I’ve seen this project mentioned and it’s interesting. Tap the power as water flows from the med to the depression, maintaining the flow as the lake evaporates. My question is - what happens with all the salts left behind?
The lake actually increases in salinity, but water evaporates and returns as rain. The salt remains behind.
A good clue as to what happens over thousands of years is the Great Salt Lake in Utah.
The east side of the lake is or was actually fairly productive farmland before it got urbanized. I think some of the most productive fruit orchards in the country were there, albeit on a much smaller scale than California.
The west side, on the other hand, is total desert. The prevailing west winds dump most of thier moisture in the Reno-Tahoe area and then moisture gets scarce as you travel eastward. You get some decent low moisture crops like hay and alfalfa around Lovelock, Nevada, but by the time you get as far east as the Utah state line, vegetation is so scarce, even low intensity sheep ranching is not possible.
If you ever have the opportunity to take I-80 or US-50 east out of the Reno area, you'll get a real education on how climate and saline lakes shape an environoment. Funny thing is, the transformation from total desert to habitable area is even more sudden going east out of the Nevada/Utah desert than going east into it.
