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

$l a t i t u \mathrm{de} \pm {35}^{o}$ from the present range

$l a t i t u \mathrm{de} \pm {23.4}^{o}$

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

N

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