ocean conditions are changing due to Rapid Global Climate Shift

[Boston]

Has the Gulf stream stopped ?

EDIT
answer is no, but there is substantial data to support it having slowed significantly and the NAO is experiencing one of its lowest moments since records have been kept

The wealth of research concerning changing ocean conditions due to Rapid Global Climate Shift is overwhelming. Large increases in wave height have been recorded and reported over the last 30 or so years in numerous oceans throughout the world.

Changes in current strength ( gulf stream down by 30% and I'm still researching one site that claims the gulf stream has stopped ) and ocean temp ( up 1°F in the over the last 100 years ) are also being studied and mapped as both these parameters play key roles in ocean dynamics

"It's a lot worse than the public thinks," said Nate Mantua, an associate research professor at the University of Washington's Climate Impacts Group.

Mantua, who's read the report, said it was clear what was causing the oceans' problems: greenhouse gases. "It is not a mystery," he said.

Virtually every parameter of ocean dynamics is changing due to Rapid Global Climate Shift

how will this effect yachting overall and on a more selfish note, how will it effect my own retirement plans ?

As I have time I'll include more and more papers documenting the changes.

That is not true. As a navigator I have used Pilot Charts for years. There isn't such a radical change. The data goes back centuries. The first publication date for the modern style pilot charts was 1847. The data shows periodic changes like the ones that are happening now. "Rapid Global Climate Shift" is one of the new catch phrases by activists. It does not have a rigorous scientific definition.

Interesting posts.

I would settle for' "The ocean conditions are changing."

I very much doubt the author of that article could recite the second law of thermodynamics.

In Patrick O'Brian's carefully researched Stephen-Maturin series, there are numerous references to dramatic, extreme or otherwise unusual climatic conditions in both hemispheres around the time Bonaparte was trying to take over the world. Those references are straight from the Ship's Logs of British naval officers over two hundred years ago. It's time we got our news from climatologists, instead of twenty-somethings with a major in Communications.

If there is GLOBAL WARMING why is there 8" of snow at my house in ALABAMA....HAHAHAHA

[cthippo]

I wonder how this will change the classification societies rules. Vessels will need to be able to handle heavier seas.

@Billy. All weather, hot or cold, good or bad, is driven by heat. More heat = more extreme weather. Same reason you get thunderstorms and hail when it's hot. The hot weather combines with the wet air to make violent storms and hail in the middle of summer.

[hoytedow]

Hail is formed when adiabatic cooling transforms water vapor in a rising air mass into ice.

[CatBuilder]

No chance the Gulf Stream has stopped. Just ask the crew of that 90' Gunboat that lost power and sail raising ability. They were fighting against it about 2 weeks ago.

Correct, but the rising air masses are directly related to air temperature.

[hoytedow]

Of course. Warm air rises. That is what makes adiabatic cooling. As warm air rises, relative humidity increases decreasing ability of water vapor to stay uncondensed. After a wild roller coaster ride in the atmosphere, the stone grows in size until gravity holds sway over updraft resulting in precipitation of icy spheroids.

its is very hard to argue with the overwhelming amount of data to support my previous statements. You may not want to believe it, but the times they are a changin and it aint looking good kids,


Britain faces big chill as ocean current slows to 1/4 of its former strength

Thermohaline Circulation and the Effects of Global Warming

Human induced anthropogenic changes in our atmosphere are no longer a matter of debate, they are fact

.

the 30% figure is one from 5 years ago in which a 30% drop in the strength of the gulf stream is noted

The ocean current that gives western Europe its relatively balmy climate is stuttering, raising fears that it might fail entirely and plunge the continent into a mini ice age.

The dramatic finding comes from a study of ocean circulation in the North Atlantic, which found a 30% reduction in the warm currents that carry water north from the Gulf Stream.

Failing ocean current raises fears of mini ice age

I've been slacking in bringing to the public eye the severity of the issues concerning the climate, the oceans reaction to Rapid Global Climate Shift, and the yachting lifestyle. Which I'd like to try and enjoy as I slowly devolve into the grumpy bastads you all seem to have become.

I read the books a long time ago but I don't recall references to weather pattern changes. I would like to check those: do you know which book(s) and the chapter numbers?

[hoytedow]

Coriolis effect plus land mass position influence currents.

[Boston]

yes, as do a few other factors, but the main driver of vertical currents is temp and salinity which are both directly related to the current warming trend of Rapid Global Climate Shift. The portion of the gulf stream that is slowing, stopped, stuttering, or moved ( I really need to weed through all the latest and figure out if that has been determined yet and if so to what degree. ) is apparently one that moderates western European weather. Not good for Europe and specifically England which will be and is being effected first.

A documented ten day halt in parts of the gulf stream 04

Prof Bryden's group stunned climate researchers last year with data suggesting that the flow rate of the Atlantic circulation had dropped by about 6m tonnes of water a second from 1957 to 1998. If the current remained that weak, he predicted, it would lead to a 1C drop in the UK in the next decade. A complete shutdown would lead to a 4C-6C cooling over 20 years.

The study prompted the UK's Natural Environment Research Council to set up an array of 16 submerged stations spread across the Atlantic, from Florida to north Africa, to measure flow rate and other variables at different depths. Data from these stations confirmed the slowdown in 1998 was not a "freak observation"- although the current does seem to have picked up slightly since.

Cold winter in a world of warming

The Gulf Stream is still flowing . I think that many of those numbers are chosen to prove an already decided upon position. That is politics and not science. They decide to pick something to blame and overlook anything else. For example, historical climate change patterns, Sun activity, volcano eruptions.
