Which increased navigational risk occurred for Viking longships attempting westward transits to Greenland?

💡 Explanation

As far north as Greenland the declination increases, causing reduced magnetic compass effectiveness because the magnetic north differs significantly from true north producing increasing errors; therefore navigation using traditional tools risked drifting off course from Greenland rather than the other options.
