I hope that you are right garinda but science is of the opinion that the Gulf Stream will not get as far north as it does today if the north polar ice cap carries on melting at the current rate, because of the density of fresh and sea water differential, not to mention the actual cooling effect of ice cold water from the arctic.

However I should have been talking about the North Atlantic Drift, which stems from the original Gulf Stream.

I may not be around to feel the effect but then no one expected well established and long standing ski resorts to be without snow and humungous chunks of the arctic polar ice detaching itself and drifting south.

Have a look at http://en.wikipedia.org/wiki/Gulf_Stream and http://www.bbc.co.uk/climate/impact/gulf_stream.shtml and http://www.ace.mmu.ac.uk/eae/Climate/Older/Gulf_Stream.html

I'm not disagreeing with you about the effect the Gulf Stream has, and how it effects our climate. My main point was that not many places of a similar latitude have the same weather, as it depends where they are placed in relation to the major continental land masses.

Sorry to disappoint you steeljack but there is a Prince Edward Island in the Indian Ocean at the coordinates I gave. In fact it is two islands one named Prince Edward Island and the other named Marion Island. Get an atlas and look it up.

I had forgotten all about the Prince Edward Island off Nova Scotia.

Lastest update......Carbon saturation in the earths atmosphere at it's highest level for 20 million years (arctic researchers)...Earth heats up, ice caps melt...sea levels rise between 1 and 2 metres (bye east anglia), ice caps melt earth gets even warmer as the caps reflect alot of heat from the sun. As more fresh water enters the seas the Gulf stream slows and eventually stops. Northern hemosphere then freezes plunging the world into a new ice age (which is several hundred years overdue). last ice age last 10,000 years.
Time to get your thermals out!!!

No dissappointment here, there may in fact be a rock outcroping in the southern Indian ocean , , but that was not the P.E.I. being discussed , it was the other one ....... the one adjacent to the route of the Gulf stream , near the Canadain mainland, the one more people know about ,that the other writer was talking about before you decided to give us the geography lesson

There is no may about it. Prince Edward Island exists as I stated and is large enough to be noted on a school atlas.

You really do need to brush up on your geography if you think that the Canadian PEI is adjacent to the Gulf Stream. The Gulf Stream starts in the Gulf of Mexico travels round Florida and up the USA eastern seaboard (to round about North Carolina) before galloping off across the North Atlantic towards us lot over here. Or put it another way it doesn’t come within 1,500 miles of the PEI that is off the north coast of Nova Scotia and New Brunswick. There is no PEI adjacent to the Gulf Stream unless you call 1,500 miles adjacent.

In any case at latitude 46 degrees north PEI is just a bit south of the UK and without the benefit of the Gulf Stream or more accurately the North Atlantic Drift, as Ianto.W. pointed out, their winters are for real. Without the benefit of the warming waters from the south we would have winters similar to theirs.

From wikipedia ......The Gulf Stream, together with its northern extension, the North Atlantic Drift, is a powerful, warm, and swift Atlantic ocean current that originates in the Gulf of Mexico, exits through the Strait of Florida, and follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean.........

if you notice, your school atlas will show , probably in the pages showing the British Empire.....Newfoundland is north-east of Nova Scotia and New Brunswick (which PEI is adjacent) therefore one would logically assume that the Gulf Stream passes this area before reaching Newfoundland and then swinging out into the North Atlantic .

Have a look at the map they so thoughtfully provide at http://en.wikipedia.org/wiki/Image:Gulf_Stream_water_temperature.jpg Where the Gulf Stream becomes the North Atlantic Drift is off the North Carolina coast. That orangy/yellow bit and that swings out north eastward across the North Atlantic. In fact it is more east-north-east.

So the map is at odds with the statement “follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean.........” However if you compare their map with the eastern seaboard of the USA that black peninsula near the top is south of Baltimore and Baltimore is nowhere near Canada.

I should imagine that the map is an image taken from a satellite and being a photograph I would suggest that it is right. Whoever wrote the text did so in the mistaken belief that the GS or NAD goes up as far as Newfoundland. That’s what they used to teach at school many years ago until technology showed that the teaching wasn’t quite correct.

In any case if Newfoundland and PEI were influenced by the GS wouldn’t they have milder winters than they do? Would the St Lawrence River and the Gulf of St Lawrence be frozen in winter if the GS went up that far?

its the fresh water in the St Lawrence river what freezes and closes down the seaway, the Maritime province ports are open

Although it's in French, the warm sea currents are in red, the cold ones being the white.

The ex merchantman who first 'wised' me up about the Gulf Stream and PEI, was on a ship that got trapped in the ice on the way to pick a rather worthless cargo up, they had to keep going back and forth for hours before an icebreaker rescued them. Hence my interest in the subject steeljack, thanks to both yourself and jambutty for the input and help, never to old to learn.

The sea currents won't change their direction, whatever happens with the temperature. The equator will always be hotter than the Poles because it's nearer to the sun. It's just the effect they may have if they become cooler or warmer, that will have an impact on places like the UK.

Just a thought garinda - if the closer to the sun one is the warmer one is, can anyone explain why there is snow on the top of Himalayas and other mountain ranges? After all the top of a mountain is closer to the sun than the bottom.

It's all down to altitude. It always amazes me when you're flying that you get ice on the plane windows. I wonder why that didn't happen to Icarus?
