Confirmed meteor asteroid or comet impacts in Holocene

(Or least it is more or less confirmed by geologists; some of these could alternatively be caused by huge volcanic eruptions)
(This theory may show that geological data may point to a cycle of a global event that recurs periodically every 3000-5000 years, bringing next global event somewhere in the next few years or decades)


Holocene meteor impacts:

Also disruption in climate (tree-ring data) at 1628 BC, 1159 BC, 208 BC (small event), 44 BC (small event), 536 AD (worldwide climatic anomalies and atmospheric dust), 829 AD (impact in Atlantic ocean: Mayans disappeared from lowlands; climatic anomalies)

207 BC and 536 BC
http://www.astronomy.com/asy/default.aspx?c=a&id=2519 and http://www3.interscience.wiley.com/journal/118807403/abstract clear evidence for a land impact in Northern Europe of a fragmented cosmic body, during the time of Celts. Dust ejected caused climatic aberrations. Crater in Chiemgau, Germany, 1 km wide comet fragmented leaving many craters in a field of about 60 x 30 km wide, of which the biggest crater is 370 m wide. Probably occurred in 207 BC, as there is evidence of debris falling from the sky from Roman authors. In 536 BC, some attribute the climatic disruption to Tambora eruption, others to a air explosion of a 500 m wide comet. The effect lasted about 20 years of worldwide disruption.

~2200 BC (supposed 2194 BC) in Iraq coast (now dry) at the time at about 10 m deep in sea, near Sumerian civilization. The event caused at least regional tsunamis. The bolide was around 100-300 m diameter and left a 3-4 km diameter crater, now a lake. This was a 200-750 megaton impact, depending if it was a asteroid or a comet. It probably caused some minor climatic impact.

Here they refer again the Iraq impact and 2354 disruption and that two Argentine craters also date somewhere in the last 5000 years ago. Benny Peiser, a anthropologist states that there are about a dozen of craters dating from the past 10000 years.

FLOOD 1
Possibly impact with significant climatic disruption at 2354 BC (until 2345 BC), possibly linked to a comet impact and consequent flood. There is research by Marie-Agnès Courty describing a air-blast explosion over northern Syria.
These fragments are possibly linked to a fragmentation of a giant comet, which gave origin to comet Encke which crossed Earth about 7500 BC and 2500 BC.

FLOOD 2
~2800 BC ( supposed 10 May 2807 BC) in Indian ocean, produced a ocean impact and a large-scale tsunami of at least about 200 m high that impacted and left many geological formations along the eastern African coast and mainly in Madagascar and Australian coast. It left the Burckle Crater, 30 km wide, 1500 km southeast of Madagascar in deep ocean at 4 km depth. This impact should have produced at least some worldwide flooding, temporary darkness and hurricane-force winds. Examples of coastal evidence from the giant tsunami include the Fenambosy chevron in Madagascar. About 30 000 megaton impact. Still lower than the 100000 megaton threshold for global catastrophe (10-20 km wide crater); but some suggest that this threshold could be higher. Which puts these Holocene impacts as only regional disaster with some but small global impact, despite worldwide flooding.

~ 3200 BC (supposed 29 June 3123 BC) in Kofles, Austria and recorded by ancient Sumerians in a cuneiform clay tablet found about 150 years ago. It left only a giant landslide, 500 m thick and 5 km diameter impact region, in the mountains of Alps. The asteroid should have impacted at a very low angle and clipped a mountain called Gamskogel, above the town of Längenfeld, about 11 km southeast from Kofles. The asteroid was about 1 km and crossed first the skies of Greece and Albania and then partially exploded in air and in the valley due to its very low angle of impact (14 000 megaton explosion!). It then projected a huge dust cloud then rose high in the atmosphere falling into the direction of Egypt and Syria (500 megaton). It probably caused very large and widespread regional damage and some climatic change.

Climatic disruption (tree-ring data) at 3195 BC
Another source puts it at circa 3150 BC http://www.geocities.com/syzygywjp/Catastrophe.html
In this source, they suggest a Mediterranean impact. Maybe the theories in 3195 BC, 3123 BC, 3114 BC Mayan date and 3150 BC are all the same event.

FLOOD 3
Climatic disruption circa 6000 BC (8k event), black sea flood (6200 BC - 5600 BC or as early as 5000 BC), 6145 BC shows a sharp sea level increase
http://news.bbc.co.uk/2/hi/europe/923400.stm

FLOOD 4
7900 BC - 7500 BC (7911 BC had abnormal volcanic activity, Autumn 7640 BC is Tollman impact theory, 7545 BC is accordingly to a source another possible date for cosmic impact)
The most probable date was really 7640 BC which shows myth and geological evidence pointing to a rather severe worldwide disaster. It was probably a comet fragmented into seven pieces that crash into ocean sites triggering worldwide flooding.

Climatic disruption end of circa 9700 BC - 9530 BC (Younger Dryas)
Or 9792 BC in some sources.

Circa 10900 BC (caused Younger Dryas) A comet exploded over land above the North American ice sheets, now Michigan, bringing a big climatic shift and mass extinction. The fireball and dealy winds were probably extended across a big part of North America. Possibly, the sudden freezing caused by ejected material lead to the rapid extinction of Siberian mammoth.

EVIDENCE OF A CYCLE, BRINGING NEXT EVENT, IN NEAR FUTURE!

Curiously we found the following recurrence of two cycles of possible meteor strikes:
3500 years and 1500 years (major cycle 5000 years)
Both are separated by 1200-1500 years apart.
Each cycle is separated by 3300-3650 years apart.
Both added together give the near 5125 years of Mayan cycle.

Events1 and Events2
10900BC (confirmed) and 9700BC
7911-7640BC (3000-3300y later, confirmed) and 6400BC/5600BC (3300y later)
5200-4370BC and 3123BC/2807BC/2354BC/2194BC (3277 to 3246y later, confirmed several)
1628BC/1159BC and 207BC/ 536AC/829AC/1159AC (3659 years later, 3636 years later, 3513 years later)

We solely don't have evidence of disruption in 5200-4300 BC period.
If we continue the cycle, the next swarm of impacts would come between now and 2200 BC, with most probability of activity mainly centered between now and 2031.
For instance, even if there is small cycles of 1500 and 3600 years, there is a significant one of nearly 5000 years (7640 BC, 2807 BC, 2026) that could be linked to Comet Encke or Taurid meteor complex intersection with Earth orbit.

Alternative theory: Possible pole shifts (given a 3657 year cycle):
Near future: North pole could move to Alaska, Eastern Siberia or somewhere in northern Pacific ocean. Europe and Greenland should warm.
1628 BC North pole moves to current position; Thera, regional tsunami, Jewish exodus and some climatic changes
5285 BC North pole moves to Greenland. Evidences of landslides in Storegga, Norway, in several places in Australia: Black sea flood
8942 BC North pole moves to East Siberian Sea, Arctic Siberia. Europe warms (ice age ends in Europe), Siberia freezes, great mammoth die-off. Extinctions in North America. This is when Ice Age ends.
12 599 BC North poles moves to Scandinavia. Ice age ends in North America!!
16 256 BC North pole moves to North America. Europe becomes also glaciated. But Alaska and Siberia are warmer.
19 913 BC Ends the peak of Ice Age. But Europe is still glaciated.
23 570 BC

Compared these impacts to the well known Tunguska impact in morning of 10 June 1908, in a remote forest in Siberia, which was a meteor of about 10-30 m diameter. The explosion is about 15 megaton and about 8 km in air (large atomic bomb was 50 megaton, the Japanese bombings were less than 0.1), limit for atomic explosions is 2000 megaton). A normal earthquake is about 1-1000 megaton, the big ones about 1000 megaton, but the Asiatic earthquake was about 100 000 megaton! Volcanoes are also about 20-500 megaton explosions, but Toba, the largest volcanic in past millions years, was about 1000 megaton. A meteor impact 2 km wide should cause about 1000 000 megaton explosion. All of these were bigger than the Meteor Crater impact caused by a 50 m meteor which caused a 1 km wide crater and 20-40 megaton impact, about 50 000 years ago.
