Below are two similiar versions of the Book of Enoch. Don't the following chapters sound like they might be describing what happens when a pole shift took place with the growing seasons for crops and fruit being backward and the moon not appearing in the sky when it is supposed to because the geological poles of Earth are reversed? It would also look like the stars in the skies had altered their orbits because it wouldn't look like they were in the sky where they used to be. Also Jesus told us that during the great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be except the days be shortened, there should be no flesh save: but for the elect's sake those days shall be shortened.
Book 3 - Astronomy
Chapter 80 http://www.ancienttexts.org/library/ethiopian/enoch/3astron/acenter.htm#80
1 And in those days the angel Uriel answered and said to me: Behold, I have shown thee everything, Enoch, and I have revealed everything to thee that thou shouldst see this sun and this moon, and the leaders of the stars of the heaven and all those who turn them, their tasks and times and departures.
2 And in the days of the sinners the years
shall be shortened,
And their seed shall be tardy on their lands and fields,
And all things on the earth shall alter,
And shall not appear in their time:
And the rain shall be kept back
And the heaven shall withhold (it).
3 And in those times the fruits of the earth
shall be backward,
And shall not grow in their time,
And the fruits of the trees shall be withheld in their time.
4 And the moon shall alter her order,
And not appear at her time.
5And in those days the sun shall be seen and
he shall journey in the evening on the extremity of the great chariot
in the west
And shall shine more brightly than accords with the order of light.
6 And many chiefs of the stars shall
transgress the order (prescribed).
And these shall alter their orbits and tasks,
And not appear at the seasons prescribed to them.
7 And the whole order of the stars shall be
concealed from the sinners,
And the thoughts of those on the earth shall err concerning them,
And they shall be altered from all their ways,
Yea, they shall err and take them to be gods.
8 And evil shall be multiplied upon them,
And punishment shall come upon them So as to destroy all.

1In those days Uriel answered and said to me, Behold, I have showed you all things, O Enoch;
2And all things have I revealed to you. You see the sun, the moon, and those which conduct the stars of heaven, which cause all their operations, seasons, and arrivals to return.
3In the days of sinners the years shall be shortened.
4Their seed shall be backward in their prolific soil; and everything done on earth shall be subverted, and disappear in its season. The rain shall be restrained, and heaven shall stand still.
5In those days the fruits of the earth shall be late, and not flourish in their season; and in their season the fruits of the trees shall be withholden.
6The moon shall change its laws, and not be seen at its proper period. But in those days shall heaven be seen; and barrenness shall take place in the borders of the great chariots in the west. Heaven shall shine more than when illuminated by the orders of light; while many chiefs among the stars of authority shall err, perverting their ways and works.
7Those shall not appear in their season, who commanded them, and all the classes of the stars shall be shut up against sinners.
8The thoughts of those who dwell on the earth shall transgress within them; and they shall be perverted in all their ways.
9They shall transgress, and think themselves (85) gods; while evil shall be multiplied among them.
(85) Themselves. Or, "them" i.e., the chiefs among the stars (vs. 6) (Knibb, p. 186).
10And punishment shall come upon them, so that all of them shall be destroyed.
The Book of Enoch (Ethiopian)
Book 1: Watchers
http://www.ancienttexts.org/library/ethiopian/enoch/1watchers/watchers.htm
Chapter 1
1 The words of the blessing of Enoch,
wherewith he blessed the elect and righteous, who will be
2 living in the day of tribulation, when all
the wicked and godless are to be removed. And he took up his parable
and said -Enoch a righteous man, whose eyes were opened by God, saw the
vision of the Holy One in the heavens, which the angels showed me, and
from them I heard everything, and from them I understood as I saw, but
not for this generation, but for a remote one which is for to come.
3 Concerning the elect I said, and took up my parable
concerning them: The Holy Great One will come
forth from His dwelling,
4 And the eternal God will tread upon the
earth, (even) on Mount Sinai,
[And appear from His camp]
And appear in the strength of His might from the heaven of heavens.
5 And all shall be smitten with fear
And the Watchers shall quake,
And great fear and trembling shall seize them unto the ends of the
earth.
6 And the high mountains shall be shaken,
And the high hills shall be made low,
And shall melt like wax before the flame
7 And the earth shall be wholly rent in
sunder,
And all that is upon the earth shall perish,
And there shall be a judgement upon all (men).
8 But with the righteous He will make peace.
And will protect the elect,
And mercy shall be upon them.
And they shall all belong to God,
And they shall be prospered,
And they shall all be blessed.
And He will help them all,
And light shall appear unto them,
And He will make peace with them'.
9 And behold! He cometh with ten thousands
of His holy ones
To execute judgement upon all,
And to destroy all the ungodly:
And to convict all flesh
Of all the works of their ungodliness which they have ungodly
committed,
And of all the hard things which ungodly sinners have spoken against
Him.
The Book of Enoch -- Chapter 1
http://www.johnpratt.com/items/docs/enoch.html#01
1The word of the blessing of Enoch, how he blessed the elect and the righteous, who were to exist in the time of trouble; rejecting all the wicked and ungodly. Enoch, a righteous man, who was (1) with God, answered and spoke, while his eyes were open, and while he saw a holy vision in the heavens. This the angels showed me.
(1) N.B. The italicized words supply a gap in the text.
2From them I heard all things, and understood what I saw; that which will not take place in this generation, but in a generation which is to succeed at a distant period, on account of the elect.
3Upon their account I spoke and conversed with him, who will go forth from his habitation, the Holy and Mighty One, the God of the world:
4Who will hereafter tread upon Mount Sinai; appear with his hosts; and be manifested in the strength of his power from heaven.
5All shall be afraid, and the Watchers be terrified.
6Great fear and trembling shall seize them, even to the ends of the earth. The lofty mountains shall be troubled, and the exalted hills depressed, melting like a honeycomb in the flame. The earth shall be immerged, and all things which are in it perish; while judgment shall come upon all, even upon all the righteous:
7But to them shall he give peace: he shall preserve the elect, and towards them exercise clemency.
8Then shall all belong to God; be happy and blessed; and the splendour of the Godhead shall illuminate them.
Chapter 2
1Behold, he comes with ten thousands of his saints, to execute judgment upon them, and destroy the wicked, and reprove all the carnal for everything which the sinful and ungodly have done, and committed against him. (2)
