I am wondering what would happen if Greenland was located 20 degrees further south, so that the southern part was at 40 N and the northern part was at 63 N. It seems like it might have a climate similar to the eastern United States and Canada at that latitude. Though I could imagine it blocking the Gulf Stream, thus making Europe cooler. What do you think?
Southern Greenland would have a really nice climate.
edit: I think 30 degrees farther south would give more interesting results though. Nuuk would be borderline subtropical/tropical, probably with substantial year round precipitation. The southern tip would have a mild tropical rainforest climate.
North America and Eurasia would probably be joined. Britain would probably have a more continental climate with much colder winters and slightly warmer summers. The south of Greenland would have a nice climate and the northern part would be as cold as much of Canada. Not sure if I'd like this world, Britain would defo be a hellish continental climate!
Cold air reaches here from Canada already so if Greenland was further south it would be almost arctic here.
The easternmost part of Greenland would be 400 miles from here I think.

The climate at the southern tip at 40N would probably be similar to Brest, France (oceanic but still cool due to the still cold labrador current that would bring down ice from the arctic ocean.
Greenland in this location would make places like London a lot colder and London's averages would probably drop by about 5C in the winter making winters there more on par with NYC and summers a little bit warmer.
Climate of Western Europe wouldn't change very much. If anything, it would be closer to the one of the Pacific Northwest. There will always be the jet stream and the Icelandic low (this one maybe enhanced). The distance between Greenland and Mainland Europe would still be relatively large, and Greenland itself may be 'disapointingly' oceanic.
Then again, when landmasses which are covered by ice are 'displaced' in these hypothetical threads, we need more information. If Greenland was magically moved right now, then it would experience a fast loss of ice which would put tons of fresh water into the ocean, causing a massive disruption of the global climate until the flow ended and the stability is restored. If Greenland in a more southern location was the default situation, the ice cap would not exist (only some glaciers around the highest peaks), the global sea level would be 6-7 metres up and the sunk inland Greenland would be above sea level.
It would shift the DC area down to FLA which would be shifted down to the equator. Most of South America from Brazil down would be antarctic as would be Australia. So much for global worming. Antarctica would be above the antarctic circle and would start to melt as would the arctic circle.
What if Hong Kong was at the bottom of the Grand Canyon?
Off topic? No, it is as relavent as the OP; both fantasy.
The inland parts (42-44N) would be extremely continental - 27C summers, -5C winters....
