Read about this scenario in the NZ in North Atlantic thread. Let's say we move Greenland South by 30 degrees latitude? How would that affect the Gulf Stream? What would the climates of NYC and London be like?

I don't know how this would effect the climate of NYC, but it would surely make London cooler. Not to mention that Greenland would actually be green.

Come to think of it I think that a good portion of Greenland would have a much more desirable climate, with it being on the Gulf Stream. Certainly a lot better then the freezing hell hole it currently is.

Sea levels would obviously rise by 10 metres, so bye-bye Rotterdam!

Freezing the Greenland's current spot sea from 67 N upwards, as would be likely would probably minimize the damage to half of that. Greenland would have a strong continental climate, whilst Europe would have a chillier four-season climate with proper winters in northern England and Scotland and similar winters to Montréal in southern Scandinavia. Summers would probably be unaffected due to the warm outflows from the Greenlandic east coast from lower latitudes.

But do not forget that much of Greenland would not be land if not for the glaciers. It'd be split into several nearby islands. There would be some serious summer vacation hotspots on those ultra-continental coastlines.

London 23/13 + 3/-3
Dublin 19/12 + 3/-2
Plymouth 19/13 + 4/-2
Birmingham 21/12 + 0/-6
Sheffield 21/10 + -2/-7
Liverpool 19/12 + 2/-4
Manchester 20/11 + 1/-6
Glasgow 18/10 + -1/-8
Aberdeen 17/10 + -1/-8
Lerwick 13/9 + 2/-5
Stockholm 23/14 + -5/-13
Copenhagen 22/13 + -3/-9
Oslo 22/13 + -6/-15

Something like that?

Well, global sea levels would be significantly higher because there would not be an ice sheet. There may actually be some pretty interesting climates in the interior of Greenland in this scenario - the ice sheet is actually "held in" by the mountains surrounding the island, so it would be in a deep valley surrounded by high mountains.

East coast of North America would probably be more continental, or maybe warmer if Greenland redirects the Gulf Stream back toward the continent. Interesting idea.

I have to admit I never even thought about the ice sheet, which makes this idea even more intriguing. But the sea levels being significantly higher wouldn't be good

I really love the thought of the east coast of North America being warmer. Especially where I'm at, which is the snow capital of Atlantic Canada.

New Brunswick would have minimal impact from a southerly Greenland due to westerly jetstream influence year round. Halifax would have a similar climate to NB though - due to colder winters.

I'm sure that this would happen.


You should make some climate guesses for the new Greenland. You seem to be really good at this.

Central inland basin at 35 N: 34/18 in summer and 12/4 in winter.

Northern tip east of Newfoundland: 17/10 in summer and -2/-10 in winter.

Coastal northerly town towards the west today at new 40 N: 24/13 in summer and 8/3 in winter... lesser moderation than in California.

Inland coastline within the split islands at roughly 42 N: 29/15 in summer and 0/-8 in winter...

Awesome.

It might take centuries, but eventually much of the submerged shelf would rise above sea level due to isostatic rebound of the crust leaving a very large island again. The melting of billions of tons of ice would leave the earth's crust in that area in a serious state of gravitational disequilibrium. As a result the semi-liquid substrate would act to slowly "fill in" the mass deficiencies and move the solid plate crust around to accommodate. This would result in lots of small earthquakes as well. This effect has been seen on the Canadian Shield as a result of the loss of ice mass after the end of the last Glacial Age about 20,000 years ago. Still a few cm's of upward displacement and small earthquakes each year.
