when you are close to the magnetic north pole, the declination will be so variable and unpredicatable that a magnetic compass becomes all but useless. You also need to consider the effect of local magnetic anomalies and polar wandering.

Yes, it is important to take declination into account when closer to the poles because the magnetic field is more inclined there, leading to larger variations in declination. Failing to adjust for declination can result in errors in navigation and orientation.
The sun's rays will strike land closer to both poles at a shallow angle, and lose much of its heat.
