Question

If the axial tilt of earth were 35 degrees, would polar regions be habitable for human life?

Answer 1

Yes! On a small scale. The population in northern Norway (latitude `75^0 N` might increase. The conditions near North Pole will become what they are now at `75^O N`

Explanation:

The tilt `35^o` instead of `23.4^o` means that the annual range for the

angle (to the vertical) of incidence of light rays, from the Sun, would

increase to

`latitude+-35^o` from the present range

`latitude +-23.4^o`

If the angle of incidence `> 90^o` on a day, the Sun will be below

the horizon,, for the whole day, and there will be no sunlight

for the day.

Now, this happens tor latitudes > 66.6^o N, at winter

solstice ( about Dec 21).

When the tilt increases to `35^o`, this limit will go up to #> 78.4^o

In view of all these points, the answer is given.
