Here's something interesting and recent;

In a recent article in a science publication, it was reported that 
there is weakening in the Atlantic Meridional Overturning Circulation,
which may be raising a lot of speculation about abrupt cooling.

It is said the last Ice Age wasn't one huge `freeze', but dozens of 
times in which temperatures abruptly rose and fell, which caused 
various ecological changes.

Ice cores from Greenland and Antarctica show that these sudden changes,
occurring every 1500 years or so were not synchronized with one another
in the two hemispheres; when the Northern would go cold, the Southern would
warm, and visa versa. Scientists believe what caused this seesaw effect
in changes to a sort of conveyer belt of ocean currents known as the 
`Atlantic Meridional Overturning Circulation (AMOC), which today drive the
Gulf Stream. They bring warm surface waters north and take deeper cold
waters south. They then weaken suddenly, almost stopping, just before an
abrupt climate change is about to occur, according to researchers report 
in Science. In a matter of decades temperatures in the North went down,
while those in the South rose.

AMOC slowdowns have long been suspected as the cause of the climate swings
during the last Ice Age, which ran from around 110,000 years ago, to about
15,000 years ago.

Man's modern recorded history didn't even start back that far (15,000 years).

The last Ice Age started with rapid climate oscillations the origin of which
remain unknown. But were most pronounced during marine isotope stage 3 (MIS3),
wh
which was the glacial period of 25 to 60 thousand years ago.

There is other information contained in this article....however it is withheld
due to the possibility that it may seen by `some' to be `occult, supernatural
or mythological', and, therefore, cannot see the light of day in this echo.
