Cold Shocks

Per an ongoing literary project, we submit the following historical correspondences:

The current Holocene Interglacial began c. 14,400 YBP (years-before-present), i.e. about BC 12,400. This coincided with the close approach --orbital perihelion-- of the Sun's obscure brown-dwarf binary companion, a Jupiter-size object in eccentric 3,600-year orbit perpendicular to the solar system's plane-of-the-ecliptic. This "Dark Destroyer," so called by ancient Sumer's "portent astronomers," next intercepted the solar system c. 10,800 YBP (BC 8800). In this case, rather than ending an Ice Age (probably by cooling oceans to reduce evaporation inland) the Destroyer precipitated a 1,500-year post-glacial "cold shock," the Younger Dryas-- not a climatic but an extra-solar event due to comet/meteor impacts per disruptions of the solar system's enveloping Oort Cloud.

From 10,800 YBP, this Younger Dryas reset the Holocene's interglacial clock to zero as of 12,300 YBP (BC 10,300). Given an interglacial period's median 12,250-year duration [min. 11,500 years plus max. 13,000 years, i.e. total 24,500 divided by two], the Holocene epoch was accordingly due to end about AD 1950 [12,250-12,300 = -50 years from AD 2000 (present)].

Combining astronomical cycles with climatological patterns, we find that AD 1950 correlates with the Destroyer's projected re-appearance c. AD 2000 [four 3,600-year cycles equal 14,400 YBP, so that the present represents a turning-point]. This implies that a cyclical termination of the Holocene Interglacial from c. AD 1950, i.e. impending re-glaciation, may be amplified by astronomical disruptions involving cloud-cover, geophysical events, impacts, as in BC 8800 (10,800 YBP).

Should this occur, an abrupt glacial "cold shock" could persist for nigh 100,000 years. No-one then or now will have anything to say about it.
