Global warming could affect the gulf stream and freeze Britain in the Winter
| The study, in the journal Nature, says it may be a response to increased melting ice and is likely to continue.
Researchers say that could have an impact on Atlantic ecosystems.
Scientists involved in the Atlas project - the largest study of deep Atlantic ecosystems ever undertaken - say the impact will not be of the order played out in the 2004 Hollywood blockbuster The Day After Tomorrow.
| But they say changes to the conveyor-belt-like system - also known as the Atlantic Meridional Overturning Circulation (Amoc) - could cool the North Atlantic and north-west Europe and transform some deep-ocean ecosystems.
Scientists believe the pattern is a response to fresh water from melting ice sheets being added to surface ocean water, meaning those surface waters "can't get very dense and sink".
| "That puts a spanner in this whole system," lead researcher Dr David Thornalley, from University College London, explained.
The concept of this system "shutting down" was featured in The Day After Tomorrow.
"Obviously that was a sensationalised version," said Dr Thornally. "But much of the underlying science was correct, and there would be significant changes to climate it if did undergo a catastrophic collapse -
| although the film made those effects much more catastrophic, and happening much more quickly - than would actually be the case."
Nonetheless, a change to the system could cool the North Atlantic and north-west Europe and transform some deep-ocean ecosystems.

| Fuck
| Guess they maybe should have thought about the environment instead of knife safety.
| This is old news, why are they making another article about it? Hasn't this been known for many years?
| This already happened in the past. Look up "river Thames ice fair". Weather changes across the centuries, this is just more politically motivated BS.

Now it could happen
A significant shift in the system of ocean currents that helps keep parts of Europe warm could send temperatures in the UK lower, scientists have found.
They say the Atlantic Ocean circulation system is weaker now than it has been for more than 1,000 years - and has changed significantly in the past 150.
