Warning signs of Gulfstream collapse

This has been a real possibility for a long time. I read an article ten years ago covering the same ground in national geographic.

It's a worry but not a new one.
 
Blumming Brexit.

In layman’s terms I would assume that means we get a lot colder? Given our latitude?
 
Gulf Stream? We get the majority of our weather from the EU, and we couldn't even agree a tariff for that. It'll all end in disaster when we have a complete breakdown in the weather supply chain; we'll be left with no weather at all.

Not any more. It's Aussie summers and winters now. 35C Christmas dinners. Although the transition will be over 10 years to allow the farmers and turkeys to adapt.
 
Over time the poles are meant to change which isn’t going to happen over night so I’d image things will get much worse than what we experience now .
Major climate change isn’t always going to be associated with our actions but nature running it’s course .

It's the magnetic poles that flip, it doesn't mean the earth is going to turn upside down! 🤦‍♂️

The axial tilt only changes a degree either side of our current axis, and takes about 50,000 years to go from one extreme to that other and back again. It is believed this cycle has been stable for a couple of billion years since the moon traveled outwards enough to regulate it.

A magnetic flip will proabably allow more harmful radiation to hit the surface, mess about with satelites, electricity grids, it'll probably impact weather and sea levels too etc. but it's hardly a species level extinction or probably even a civilisation ending scenario. It might also not happen for another 100,000 years so I wouldn't get too hung up on it. the last one happened about 40,000 years ago and they believe it happens every 250,000 years, again don't get too hung up on it.

So I shouldn’t be sat on the edge of my seat waiting for it then ? Cheers 👍😎
 
I tried to explain the Gulfstream to a young Rumanian who had been on holiday to the West of Scotland.

All it proved is that it was a good thing I never went into teaching.

Absolutely right - how much climate change is due to mankind, and how much is down to natural cycles?

I believe that the climate is changing but I'm very skeptical that we have much to do with it.
 
Hypothetically, even if 1% of change is directly linked to human behaviour (for the record I believe it's much more) - wouldn't you want to act to try influence what you can? Ultimately it's the continued existence of the human race which is at stake here.

It may all be futile eventually, but I'm not sure this falls into the "too hard/can't be bothered" basket.
 
There are a lot of scientists sceptical about the collapse of the gulf stream. To much water flows through it, 4 billion cubic litres per second, for desalination from melting ice to adversely affect it.

I have no idea, but did read about this a few years ago.

As for mankind not contributing to global warming... Most scientists think its a fact but it is based on collection of historical data over a miniscule period of time, geologically speaking.

The problem is, if mankind speeds up this process by only a little it can still quicken its impact on life on this planet.

Geologically speaking we may be making little difference but that small difference may end human life several thousand years before it otherwise would, if nature were left to its own devices. That's the problem. Nature would get there on its own, eventually, let's not do anything to speed it up until we have an interstellar migration programme.

I'm pretty sure the existence of the human race isn't at stake?

Our current way of life and complex societies may well be, I envisage it will be a bit like mad max/ dark ages (early medieval) for a few hundred years before things start to rebuild.

Definitely not fun times to live through but humanity should survive it.

Language clarified by another expert & said the newspapers are being imprecise.

Gulf stream is driven by winds & so it will continue, although with the loss of AMOC, it is likely to be more direct east / further south than it currently is.

They agreed with the possible impact on global weather though as highlighted in the article:
severely disrupting the rains ... in India, South America and West Africa; increasing storms and lowering temperatures in Europe

Said a similar mini event in the late 70's early 80's lead to drought, war & then the famine in Ethiopia.
