"What's going on? Well, the Arctic gets just as many hours of sunlight
as anywhere else on Earth - in fact, just a tad more. The reason the
Arctic is cold is that the Sun never gets very high above the horizon,
so its light always hits the ground at an oblique angle.. "

The idea of variable inclination of the Earth to the Sun and
subsequently inclination of solar radiation as the main cause of Artic
conditions is incredible in this day and age when it is possible to
look down at the region andf the planet from space.
An intelligent astronomer begins with a basic fact -at the Equator
there is no variation in inclination and daylight/darkness remains
constant through the annual orbital cycle of the Earth.The observed
hemispherical differences of apparent variation in inclination leading
to seasonal variations in daylight/darkness where they become extrem
at the geographical pole is due to the orbital motion of the Earth
rather than the pseudo-dynamic of variable axial tilt.
It is actually possible to see from space that the solar radiation/
orbital shadow boundary changes against fixed axial orientation
leading to the important working principle that the main cause for
Polar conditions relies on the length of time a location spends in
the orbital shadow of the Earth allied with local oceanographic and
other factors,the inclination of solar radiation being among minor
causes.
The new astronomy is actually looking down at the Earth from space and
drawing accurate working principles for climatological,geological and
many other purposes _
