The AP has an article up on how global warming is causing the Mediterranean Sea to get saltier. Often in articles like this, there are a few lines that people without scientific backgrounds read, but have no idea if they’re true or not…like this passage:

“The Mediterranean is becoming warmer and saltier” due to increased evaporation, Ferrara told the conference, which was held at the Rome-based U.N. Food and Agriculture Organization. Ferrara said this could disrupt the flow at the Strait of Gibraltar, a key gateway to the Mediterranean. The higher salt concentration in the Mediterranean would cause water to flow out into the Atlantic Ocean, as opposed to Atlantic water coming into the Mediterranean, which serves as the sea’s lifeline.

I’m not really sure how or why saltier water would flow into less salty water, but maybe it’s true. Anyway, while trying to find out the answer to this question, I found this article on one of the effects of a too salty Mediterranean that the AP failed to mention:

MINNEAPOLIS / ST. PAUL–About 150,000 years ago, an anomalous ice age was triggered by an increasingly salty Mediterranean Sea, a development that’s occurring today and may start new ice sheet growth in the next few decades, according to a study at the University of Minnesota. Robert Johnson, an adjunct professor of geology and geophysics, will present his study of the glaciation 150,000 years ago and discuss its implications for today’s climate on Tuesday, Oct. 29, at the annual meeting of the Geological Society of America in Denver.

How it works: At the Strait of Gibraltar, deep, salty Mediterranean water flows into the Atlantic and northward as it mixes up into the salty Gulf Stream surface water. Today some of that mixture flows westward into the Labrador Sea Southwest of Greenland, and much of it also flows beyond the Faeroe Islands off Scotland and eventually into the Arctic Ocean. About 160,000 years ago, an ice age was already under way, and the seas east and west of Greenland were very cold. But the salinity of the mixture reaching Labrador made the water dense enough to sink easily when cooled in winter, and the warmer salty replacement mixture kept the seas south of Greenland relatively warm.
“Storms usually track over areas where warm and cold conditions exist side by side,” said Johnson. This temperature contrast with the Greenland ice sheet and other cold areas kept eastward-moving storms to the north. This channelled large amounts of moisture over both European and Siberian areas, causing enormous growth of the ice sheets there.

Good news. Global warming will cause an increase in ice sheet growth. Problem solved.
