Dead starfish wash up on beach

HUNDREDS of dead starfish were washed up on a beach in the second such incident in south-east England. They were found at Brighton, Sussex, 10 days after a similar find in Kent. The Environment Agency is investigating.

Scientists blame ocean dead zones on climate change

Peering into the murky depths, Jane Lubchenco searched for sea life, but all she saw were signs of death.

Video images scanned from the seafloor revealed a boneyard of crab skeletons, dead fish and other marine life smothered under a white mat of bacteria. At times, the camera's unblinking eye revealed nothing - a barren undersea desert in waters renowned for their bounty of Dungeness crabs and fat rockfish.

"We couldn't believe our eyes," Lubchenco said, recalling her initial impression of the carnage brought about by oxygen-starved waters. "It was so overwhelming and depressing. It appeared that everything that couldn't swim or scuttle away had died."

Upon further study, Lubchenco and other marine ecologists at Oregon State University concluded that that the undersea plague appears to be a symptom of global warming. In a study published in the journal Science, the researchers note how these low-oxygen waters have expanded north into Washington and crept south as far as the California state line. And, they appear to be as regular as the tides, a cycle that has repeated itself every summer and fall since 2002.
 
Bad news stories, but both don't appear to have anything to do with thermohaline circulation as suggested by your topic title.

it seems more like evidence of a possible oceanic anoxic event, where oxygen levels in the oceans are depleted. Thermohaline circulation is to do with the circulation of warmer and cooler waters, the much talked about "conveyor belt" of heat energy around the earth in the oceans.

Correct me if I'm wrong though.
 
At least there are a lot of bacteria. They'll evolve and we'll have new species hundreds of thousands from now.

Presently, this is awful news. It can be foreshadowing the potentially devastating effects of global warming.

starfish are extremely important in the field of regenerative medicine. you can chop a starfish into 5 sections and it will grow into 5 new starfish.

as for the natural selection part, hopefully all the starfish in that area didn't die. if the strong remained, they will reproduce and hopefully make up for the loss. it's still sad to see all those dead starfish.

Then what you are saying is that it isn't global warming.
 
"starfish are extremely important in the field of regenerative medicine. you can chop a starfish into 5 sections and it will grow into 5 new starfish."

Solution. Annual mass congregation of environmentalist chefs take cleavers to remaining starfish, thereby replenishing the population.
 
The Mystery of Global Warming's Missing Heat
by Richard Harris,
NPR.org

· Some 3,000 scientific robots that are plying the ocean have sent home a puzzling message. These diving instruments suggest that the oceans have not warmed up at all over the past four or five years. That could mean global warming has taken a breather. Or it could mean scientists aren't quite understanding what their robots are telling them. (read more)
 
No, no word game. I just was not to sure what you were saying.

According to satellite data there has been no globally-averaged atmospheric temperature increase since 1998.
 
Climate change might have played a roll in this, this has been a very interesting couple of weeks, the breakup of a large section of Wilkins Ice shelf earlier in the week, and now this. but this could also be natural.
 
NASA's Argos buoys have shown a slight ocean cooling. Eight weather satellites have shown an averaged 0.14C warming of the atmosphere over the last 30 years - well within natural fluctuations. That kind of atmospheric warming will not cause large Antarctic Ice Shelves to break off. In fact, the Antarctic ocean ice extent recorded in 2007 was one of the largest.
 
all I was stating was, its been interesting due to these natural phenomenon happening over the last few weeks, I have no desire to revisit the "Climate Change" thread fiasco again.
