What scenario would exist if the Earh north pole was only 1 degree tilt?after complete precession?

Answer 1

Very interesting question. Nobody really knows the true answer since we do not know of a planet of similar composition and orbital position to ours that doesn't have a rotational tilt like our planet. As it is, earth has a 23 degree axial tilt which gives us our seasons. Without this tilt it would definately be much hotter at the equator, and much colder at the poles... It is quite possible that without our planet's axial tilt life would have had a much harder time expanding over the globe as it did. If the poles were kept cold long enough it is possible that the polar ice sheets would extend south/north far enough to create a snowball earth which would make life all but impossible for anything but the hardiest micro-organisms.

Anyway... I'm just giving my best guess, which is all anyone can really do. I think we should be thankful that we have our axial tilt, as it keeps the climate relatively moderate for much of the globe.

Answer 2

There would be very little difference between the seasons.

Answer 3

It would be like the spring or vernal equinox every day.
