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#

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.

Yes, the polar regions would probably be habitable for human life if Earth's axial tilt were 35 degrees; however, this would mean that seasonal temperature variations would be more severe than they are now, at roughly 23.5 degrees. The habitability would depend on a number of factors, including atmospheric conditions, resource availability, and adaptation strategies.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
