It is important to take the declination into account when one is closer to the poles because declination varies more as a function of longitude and not the latitude. In North America, if one goes toward the east coast, the declination increases to the west. If one goes to the west coast, the declination increases to the east.
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.
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. felicity knows whats up<3
As you get closer to the poles, the angle of declination, which is the angle between magnetic north and true north, tends to increase. This is because the magnetic field lines converge toward the poles, causing the magnetic north to deviate more significantly from true north. Near the poles, the declination can become quite large, and in some locations, it can even reach 90 degrees, where magnetic north aligns almost directly overhead.
The angle between the geographic and magnetic poles extends more towards the east, as you move to the north. The magnetic pole is actually near Greenland.

Variation in the Earth's magnetic field: The outer core of the Earth is in constant motion, leading to changes in the magnetic field over time, causing magnetic declination. Local magnetic anomalies: Presence of magnetic minerals or man-made structures in the vicinity can distort the Earth's magnetic field, affecting the accuracy of the compass reading. Distance from magnetic poles: The closer one is to the magnetic poles, the greater the magnetic declination due to the convergence of field lines.
The sun's rays will strike land closer to both poles at a shallow angle, and lose much of its heat.

The hole in the ozone layer happen to be closer to the poles. It is because the ozone depletion occurs in very low temperatures which can only be obtained at the poles.
The closer you are to the poles, the greater the change.
