Atlantic Ocean circulation nearing ‘devastating’ tipping point

Or it might turn out that another part of our planet will offer the best chances of survival and we Brits could become the migrants!

People migrating from Africa etc because of climate conditions is nothing new. This article is 13 years old and more than likely it’s been happening for eons.

I don`t need scientific papers ww. I studied oceanography and geophysics as part of my scientific background. I am definitely not a scaremonger, unlike some who like to subliminally worry people and seem to spend all their waking hours doing so. Misery does indeed like company

We are witnessing huge changes more rapidly than the catastrophic changes which have occurred over millennia and we need to adapt.
The alternative is extinction.

My AC are well-educated, well-travelled and intelligent. Yet they don't seem to heed the warnings. They are always buying yet more and more stuff for their houses and they think nothing of jetting off on holiday. I have gone on and on about the effect on the environment to no avail. I think most people of a similar age are the same. I think most of them think that somebody else will sort the problem. And yet if that generation isn't too bothered there isn't much hope. I'd be an activist if I was younger.

Then it seems that you need to get more up to date.

My son, an environmental scientist works extensively with climatologists, and his profession involves mitigating against climate change.

So I listen to him and am thankful that there are agencies that do indeed listen to and take action to try to reduce devastation that is and will be caused by climate change.

So he has been involved with flood defence, both structurally and naturally, and in doing so, he makes every effort to put value back into the natural environment.

Positive action is the way to go!

Thank goodness for people like your son Whitewavemark..I remember James Lovelock's predictions so many years ago when people ridiculed him.. His predictions have happened sooner than even he thought possible.. and yet still some people choose to ignore what is happening..

Worth reading this article in the Daily Telegraph
www.telegraph.co.uk/news/2024/02/09/climate-change-modelling-wrong-claim-uk-scientists/
which quotes British scientists pouring some much needed 'cold water' on the florid claims made in the study - and how its authors fiddled the inputs to get the outcome they desired.
An extract:
However British scientists warned that the outcome had been “forced” by using unlikely variables, such as assuming large influxes of freshwater into the Atlantic.

Prof Jonathan Bamber, director of the Bristol Glaciology Centre at Bristol University, said: “They did this by imposing a huge freshwater forcing to the North Atlantic that is entirely unrealistic for even the most extreme warming scenario over the next century.

“Their freshwater forcing applied to the North Atlantic is equivalent to six cm/year of sea level rise by the end of the experiment, which is more than seen during the collapse of the ice sheet that covered North America during the last glaciation.”

The UN’s Intergovernmental Panel on Climate Change has said that the AMOC is unlikely to collapse this century, and many scientists do not believe it will fail even if the climate continues to warm.

In 2006 Lovelock predicted that by the middle of this century that most of the Earth would be uninhabitable

Clearly an extreme prediction

Migration is not primarily due to climate it is Economic or Political migration, in many parts of Africa in particular population growth has exceeded the capacity of the country to feed itself.

but sadly becoming true.. it's only 26 years away..

Migration is not primarily due to climate it is Economic or Political migration, in many parts of Africa in particular population growth has exceeded the capacity of the country to feed itself.

The other thing about is that parts of Africa are so productive and could feed the whole continent, were it not for wars and conflicts, even within nations.

Please excuse typos.

Africa could easily feed itself, even with its higher population but tribalism, wars and corruption continue to make cooperation between states impossible.

It seems to me that we human beings have created more pollution during the last 150 years that at any time previously. We are seeing evidenee of climate change all around us. Ice caps melting, glaciers disappearing, severe coastal erosion along the coast in Suffolk and Norfolk, lakes appearing in parts of Amerrica which have been dry for may years extreme flooding in the Southern USA etc etc. And yet some people prefer to ignore this evidence.

Apologies for any typos - recovering from a cataract op and can't quite see clearluy close up.

I’m just glad I’m at this end of my life and not a young person.

Dinahmo re cataract op. I found some non prescription spectacles in local pharmacy to tide me over until checkup and new prescription in 6 weeks. Also magnifying glasses help.

What’s up with that today explains the thinking behind the tipping argument. In essence we would need to wait about another 2000 years or so to tip plus 7 x more water is needed to tip than is currently on the planet. Chill.

And good old rishi Sunak is signing off on hundreds of gas and oil drilling permits for the North Sea. Wonder if the Tories and their supporters have a bolthole to go to when everything goes to s...? Sorry about the rant - just cannot believe what this evil government has done to us!

Ah....the Guardian!

Ah....the Guardian!

And a lot more.

Also, views from a number of scientists

www.sciencemediacentre.org/expert-reaction-to-modelling-study-suggesting-atlantic-ocean-circulation-amoc-could-be-on-course-to-collapse/

Consensus seems to be that there is uncertainty, but that we shouldn't be sitting back waiting for it to happen...

These doom and gloom stories have been doing the rounds for several decades to my knowledge and probably longer.

I for one am extremely relieved that Rishi has signed further contracts for North sea oil and gas drilling.
He is trying to keep us as self sufficient as possible for as long as possible.

Of course if Starmer does get in all that will change.

Our own Met Office say that any changes in Atlantic Circulation is very unlikely and they have no axe to grind.
I’m happy to go with an unbiased opinion rather than one with a vested interest.

Scientists get research grants so it’s in their interest to spread doubt and uncertainty, nobody is going to get funding to research that it’s all fine.

CO2 emissions are still rising, there is no indication that they will fall in the foreseeable future, possibly not until global population reduces sometime next century.

I think you have a very odd view of science, Katie59. Very odd, indeed.

They get research grants to research Katie, not to prove their pre-judged conclusions. Also they publish their methods and all the data they based their conclusions on, so any errors in analysis can be discovered by others in peer-reviewed journals.
