Local Beaches Awash With Dead FishAP, Aug 4
OCEAN CITY, Md. (AP) - A surge of cold water generated from an offshore current killed nearly a million adult Atlantic croaker, leaving maintenance crews at local resorts with their hands full of carcasses to clean up.
In Ocean City, maintenance crews scoured the beaches Tuesday picking up and disposing of hundreds of dead Atlantic croaker - a silvery greenish and grayish fish with brassy spots - who succumbed to thermal shock.

The Maryland Department of Environment on Tuesday attributed the cause of the deaths to a sudden temperature drop in the water. No other species of fish or marine animals are believed to have been affected by exposure to the cold water temperatures, and tests for harmful algae blooms and bacteria have come up negative, according to spokesman Richard McIntire.
McIntire said several hundred thousand to slightly more than a million croaker have died.
"They were probably swimming in water temperature around the 60 degrees," he said. "Then it got down to the 40s. Just like humans, some of us suffer heatstroke or suffer frostbite at different temperatures. Same thing with fish. They couldn't handle the rapid temperature drop."

GREENLAND’S cover of ice is melting ten times quicker than previously thought, an increase that could lead to floods across the world, scientists have found.
Newly published research shows an alarming rise in the rate of collapse of the massive Greenland ice-sheet as a result of global warming. Scientists now believe the ice-sheet is shrinking at the rate of ten metres a year, not the one metre previously thought
...
One medium-term side-effect of the destruction of the Greenland ice-sheet could be the loss of the Gulf Stream, which keeps Europe warm and temperate. The fresh water from the ice mixes with the salt water in the sea, altering the salinity and changing the direction and behaviour of major currents.
