Warming waters a major factor in the collapse of New England cod, study finds

For centuries, cod were the backbone of New England's fisheries and a key species in the Gulf of Maine ecosystem. Today, cod stocks are on the verge of collapse, hovering at 3-4% of sustainable levels. Even cuts to the fishery have failed to slow this rapid decline, surprising both fishermen and fisheries managers. For the first time, a new report in Science explains why. It shows that the cod collapse is in large part due to rapid warming of the ocean in the Gulf of Maine - 99 percent faster than anywhere else on the planet. The rapid warming is linked to changes in the position of the Gulf Stream and to climate oscillations in the Atlantic and the Pacific. These factors add to the steady pace of warming caused by global climate change. In the face of already depleted cod stocks, fisheries managers in 2010 had placed a series of restrictions on harvesting this key Gulf of Maine species, but even strict quota limits on fishermen failed to help cod rebound.

Hmmmm. Just another one to add to the long list of all the other things AGW is allegedly responsible for

I'm still not feeling guilty :cool:

Yep. Cod is on the list.

There is something a bit suspect in the timing,
The Cod hit a major decline in 1992,

Most of the rain use to be absorbed by the open ground, and only some of it making it to the Gulf of Maine from rivers. So much more fresh water is now going directly to the sea through storm sewers.

If you read the various material of this area, they have studied it for well over a decade. Land use changes are the largest contributor to the reduction of salinity, plus this the area has been getting more than normal rainfall. The salinity changes affect the food chain.

What we are seeing now is not a surprise, and it has nothing to do with temperature or CO2. It's salinity changes.

That brings up a interesting point, when the midwest was the dust bowl, the CCC dug millions of ponds and planted tree rows,
to slow down the wind and keep some of the water.
A dug pond will only last about 60 years, before nature starts some serious reclamation.
That combined with all our new concrete, could alter the flow patterns.

Man does have a notable effect on the climate. Too bad they want to only focus on greenhouse gasses, which likely do us more good than harm.
 
Here is something I found that's informative.

I would be curious what is happening to what they feed on and dredging practices.

1992 is when the Canadian government implemented a Cod Moratorium, to prevent overfishing. Drag-net fishing had become popular and modern technology made it possible to harvest enormous quantities of fish, beyond which natural reproductive processes could replenish. You can read more about it here. It was a major crisis on all levels.

Global fish stocks are currently threatened by over fishing, but also temperature increases. This has been known for the better part of a decade now. All nations with coastal communities whose primary food source is fish are already feeling the pressure, especially undeveloped nations. Fish like Atlantic cod need the colder temperatures for survival. In general, fish that don't have suitable temperatures in their environments start getting stressed out, stop reproducing, and become more vulnerable to disease. Have you ever had an aquarium at home? Same principle, but on a global scale.

Human activities are screwing this planet over. We're pumping out greenhouse gases at unprecedented rates while also destroying all the natural reservoirs that would naturally sequester the excess, like the rainforests.

Indonesia's ecosystems are totally on fire right now thanks to slash burning that got out of control, and the media isn't even talking about it. It's predicted to be the worst ecological disaster in a century. The loss of rare species is going to be hard to tabulate, and there has already been more CO2 released than the entire U.S. economy releases in a single year. All because some idiots wanted to make a buck on palm oil.

We do have the ability to foul our own nest, but in the case of the cod,
I think overfishing is the culprit not the warming water.
 
Warming waters?

It's not global warming...it's way more people in the world then ever before and too many of them are peeing when they go swimming in the ocean.

:wink:

Of course you do.

Classic.

Article is published in Science.

Denier has a small amount of knowledge on subject.

Without reading paper, denier disputes experts on topic, because he doesn't want to believe in AGW.

Repeat with any AGW topic and multiply by 'x' deniers for an orgy of ignorance.

The evidence shows that both problems are occurring simultaneously. Countries like China, Russia and the U.S. don't obey moratoriums once they reach international waters. That's where most of the damage is being done.

But warming waters are changing reproductive patterns of many species all over the world right now too.

Sea sediments show that warming and cooling phases like we see today are a natural phenomenon that has occurred dozens of times since the last glaciation. Todays warming is very modest in terms of both its level and rate of change. Some species will thrive and others won't its just nature doing what it does

Whatever... I'm not going to argue with someone who has their head in the sand and has already made up their mind.

History will judge this human era as incredibly selfish, destructive and wasteful, and there will be plenty of examples of propaganda used to excuse the continuance of such behavior.

All the real evidence shows that ecological disaster is happening on an exponential scale, but I have no time or desire to regurgitate such information for you. :shrug: Fortunately, the green industries are already starting to gain headway in many parts of the world, so the kind of dinosaur thinking which perpetuates human stagnancy will be a thing of the past in the coming decades.
 
yep now good old pumpkin carving causes global warming. I wish these people would stop putting climate change in there.
lol what will these people come up with next.

Is climate change what lights up the pumpkin?

I guess global warming is now helped along by people lighting pumpkins.
these fools can't get any dumber but I bet they will.

ol yea they did get dumber

PRUDEN: Flatulent cows and the global warming scare - Washington Times

seriously folks you can't make this crap up and call it science.

Cows emit a massive amount of methane through belching, with a lesser amount through flatulence,” explains How Stuff Works, an Internet website. “Statistics vary regarding how much methane the average cow expels. Some experts say 100 liters to 200 liters a day … while others say it’s up to 500 liters a day.”

Malthusian population growth may be facing us more and more as we approach the 10 billion projected limit for the Earth.

It is convenient to dump runoff and treated sewage into the seas, but it is probably not a very good idea.

Salmon on the West Coast have also declined dramatically to the extent where state fish and wildlife departments have had to call off salmon seasons.

At some point we will reach the Malthusian limit.

That's when farmed fish and poultry will need to become our major source of meats, with a few calves from the dairy industry, goats and sheep from the wool industry, and the omnivorous pigs will need to feed us meat.

I personally do not believe that global warming and other Malthusian trends are reversible. We just need to live with it.
 
Whatever... I'm not going to argue with someone who has their head in the sand and has already made up their mind.

Now just wait a minute there bud I've made up my mind based on facts and evidence. If emotion works better for you then good luck with that. You are the one having made up their mind based on media driven hysteria about a minor temperature fluctuation over a few decades

If you don't like the facts being presented to you then don't post here. Get a placard and go on an anti globalisation march somewhere if that makes you feel better

Pollution and resource management is one thing this AGW malarky is quite another.

Fortunately, the green industries are already starting to gain headway in many parts of the world, so the kind of dinosaur thinking which perpetuates human stagnancy will be a thing of the past in the coming decades

Fortunately many western governments are now dumping green energy as fast as they can because experience has shown they are too expensive and impracticable to be viable
