Science of dating events using ice Futanari gratis chat dating
Although naturalistic science claims to be neutral and unbiased, it starts with this bias.
Making a distinction between operational (observational) science and historical (origins) science helps us to understand the limitations of these naturalistic presuppositions in science.
The comparable climate cyclicity during the Holocene is referred to as Bond events.
The best evidence for Dansgaard–Oeschger events remains in the Greenland ice cores, which only go back to the end of the last interglacial, the Eemian interglacial.

They further suggest the existence of a window of AMOC bistability ('sweet spot' for abrupt climate changes) associated with ice volume and atmospheric CO2, accounting for the occurrences of D-O type events under intermediate glacial conditions in the late Pleistocene.
Unfortunately, current ice core records from Greenland extend only through the last most recent glacial period so direct evidence of D-O events in earlier glacial periods from Greenland ice is unavailable.
However, work by Stephen Barker and colleagues has shown that the existing Greenland record can be reconstructed by deriving the Antarctic ice core record.
The mean observed stratospheric transport and deposition time to Law Dome from the eruption site is 1.5 years (σ = 0.6 years) from 11 well-dated eruptions. This event is also observed in other ice core records and is attributed to the volcano Kuwae, with an eruption date in the range A. 1455.9–1459.9 if all sources of error are considered.
