Well to be honest Europe in General is a pretty bad Idea, with Russia wanting to be stronk again I wouldn't want to do anything near there for any Long Term Periods of time.
As for locations:
>Tasmania
>Northern Alaska near the town of dead horse
>British Columbia
>New England area
Though Greenland seems like a better Idea because of all the Mining industry starting out there, and there are plans for developing the region but people need manpower to do it.
For example using the rubble rock from mining being dumped into the sea eventually expanding the coast and allowing for more flat fields that can sustain crops or grass which would help stimulate the ecosystem.
