Collapse of Atlantic current may be imminent

Thank you for posting. An underappreciated concern regarding a heating planet.

 

If the current stops or slows, the north gets colder. Is that the earth cooling itself?

 

At least it wasn't an off topic

 

They made a movie about this....20 years ago

 

Interesting to contemplate but the other effects might be catastrophic

 

Part 1 of your statement I agree with.
Part 2 It's a natural process.

As a poster that I percieve as believing in science, I would suggest to you, that the subject trickster is posting about should be of serious concern.

I assume you are familiar with the Younger Dryas Climatic period: 12,900 to 11,700 BP.

A subject that has been, and continues to be, much scrutizinzed.
Fot those thqat don't know, this period is distinguished by a bizarre period of cooling.

The climate had been experiencing a general trend of warming (exemplified by the melting of the Laurentide Ice Sheet that covered Canada and a good part of the Northern USA.) for thosands of years.

Then (oddly) for 1200 years the earth cooled. Then warmed up again.

Why should "WE" care about that?

The Greenland Ice-Core study shows some REMARKABLE temperature variations at the time of the Younger Dryas and before the Younger Dryas event. As in temperature flutuations
up to 15 even 18 degrees in a relatively short time span. Some say as short as hundreds of years but more concerning, some scientists interpret the data to suggest temperaure fluctuations were in much briefer time intervals - as in 10 or 20 years.

What happened in the Younger Dryas? The extinction of a wide variety of MEGA-FAUNA all over the planet but in particular in the Americas.

It should also be pointed out that during the melting of the Laurentide Ice Sheet Sea levels ROSE by as much as 300 feet.
The coasts were many miles from there present position.

The mos devastating point in all this is drastic temperature change. Should temperatures rise or fall anywhere near double digits Agriculural production, world-wide, would plunge.

Resources humans depend on would be changed.

I have menioned this in previous posts, ICE Core data show that world wide, climate has been quite stable since the Younger Dryas event ended. A gradual but realatively stable warming trend with minor temperature flutuations have been a driving force for humankind to floursh on the planet the last 10,000 years.

Should climate temperatures revert to wildly oscillating levels, as the Ice Core data from the pre Younger Dryas period shows, the Human species will no longer be pissing and moaning about politics, gender and wealth distribution.

Humans will be fighting like Neanderthals in the struggle against nature to survive.

 

As I understand it, England would look more like Greenland if it weren't for this particular current. I don't know how it effects the rest of Europe.

 

once the ice was of sufficient volume, it would seem that the current would reestablish itself as the cold water sank and refueled the engine that drives the current. the side effects in the meantime would definitely lead to disruptions and forced adaptations.

 

Just curious, for those that don't agree that mankind's behavior is the cause of global warming OR that global warming doesn't exist, what led you to that belief? I'm genuinely curious, no prepared "gotchas".

 

Will the Gulf Stream really collapse by 2025?

But scientists including Ben Booth at the Met Office Hadley Centre say the paper's conclusions "are far from settled science".

"We just don't have the evidence to state that it has declined," says Prof Penny Holliday at the National Oceanography Centre, University of Southampton.

"We know that there is a possibility that Amoc could stop what it's doing now at some point, but it's really hard to have certainty about that," she says.

The reasons for many scientists' reservations is that they say the study's authors made a series of assumptions about how to understand Amoc.

But the climate system is extremely complex and experts do not have all the evidence they need to fully understand the Amoc.

The predictions that it could collapse as early as 2025 or by 2095 should be taken with a large grain of salt, says Jon Robson at the National Centre for Atmospheric Science, University of Reading.

 

If I may be so presumptious (I am firmly on the side of man made climate change as it relates to rising Co2 levels):

1) As I mentioned in my earlier posts extreme temperature variations have been shown in the Greenland Ice Core data. Pre Human industrialization. So no Exxon - So why??

2) Volcanism / supervolcanic events
3) Bolide or space impactor
4) Tilt of the earth (change) on it's journey around the Milky Way Galaxy
5) Extreme methane releases, from the ocean or permafrost regions.
6) The sun / super flare
7) Changes in the earths inner, outer cores or the mantle - loops back to #1.
8) And finally, in a nod to the OP - Changes in the earths oceans and seas circulatory systems)

From what I have read. I am no scientist.

For skeptics, (or the interested) I suggest that they look at the Ice Core
temperature range graphs that have been published. The temperature variations are SHOCKING, pre Younger Dryas. There appears to be numerous factors that affect climate and temperature change and it's not just human industrialization. Humans just added another component into the equation.

 

The filth of our touch is an apocalypse.

Yellowstone

 

Hi Homer,
Sadly I have become quite the narrcissist in my posts regarding humanity and our behavior.

I do not believe that supernatural being are in charge of our creation or our demise, thats just my opinion, and I mean no disrespect if you do not agree with that.

I do believe that planet Earth is worthy of respect if not worship.
It seems to me that our species see's it and every living thing on it as an exploitable commodity, to be devalued as seen fit by the masters of capital or military power.

The pacific ocean is now the pacific DUMP. I have been watching countless videos of sea creature "rescues" from rash or fishing nets. Pretty sad. Of course that does not take into account the marine harvesting "super-ships" that are devouring and destroying everything in their path.

Just today I read that 1/3 of all vertebrate species on this planet are used for food or resource consumption / exploitation.

Now if you were an alien showing up, how would YOU view that?

Funny how the religons of the world descibe ourselves as "holy" or sitting on the right hand side of whatever god they worship.
I must say, if that is true, I am not particularily impressed.

OK back to Yellowstone -
Is just one of many caldras with Supervolcanic histories.

Interestingly Yellowstone, and the series of caldera's around it are like the Hawaiian Islands. Apparantly these are mantle "Hot-Spots" - In other words as the tectonic plates move and slide, they slide over a zone that has periodic but IMMENSE super-eruption events.

The hot spot does not move, it just erupts periodicly in these places. The time gaps are enormous, the Yellowstone area erupting at intervals of around 600,000 years but not in all cases, I recall one time gap of 1.3 million years in the yellowstone case.

 

Earth is 4.5 billion years old ……a mere 45 years ago the ‘ settled science/Consensus’ was calling for impending ice age (Google time magazine penguin cover). Now my generator at a Gator tailgate is causing global warming and we have to destroy any civilized progress and bankrupt ourselves for someone else’s religion. The thought that the world has survived 4 billion years without adjusting for temperature changes is absurd. Even recently we were all hen pecked to death about warmer water temperatures destroying the Great Barrier Reef, and drum roll. Nature made adjustments as it always does and now the Great Barrier Reef is flourishing. Shocker, NOT! And no it is not flourishing because John Kerry dropped a green peace bomb. The water is warmer and new coral has grown. Period. Anyone with an ounce of humility and integrity would admit it and pause and reflect. Did they? Nope. Double down and continue the con and say we just more time and more money. First rule of the Con is always stay in the con. Just as the Great Barrier Reef adjusted so will the rest of the globe… if anyone is alive long enough to live through the natural periods of cooling and warming, you will witness it too. So yes I double bacon disagree with OP and the ‘man made’ Nonsense….aka global grift

 

I was wondering why it got so cold in Ukraine during the winter so I took a look at a map of Europe. The southernmost parts of continental Europe appear to be at about the same latitude as North Carolina, so most of Europe climate is probably about like that of let's say, Kansas and states further north and Canada. Brrrrr!!!!
