Science of dating events using ice

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.

Without the supernatural, there is no basis for logical, orderly laws of nature.

In its original form science simply meant “knowledge.” Now, the denial of supernatural events limits the depth of understanding that science can have and the types of questions science can ask.

In addition, no permission is required from the rights-holder(s) for educational uses. 1301–1995 has been extracted from three Law Dome ice cores (East Antarctica). Signals from 20 eruptions are preserved in the record, including those of two unknown eruptions with acid deposition beginning in A. The latter modulates atmospheric inter-basin freshwater transport across Central America, which changes the freshwater budget in the North Atlantic and thus the circulation.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.Although the effects of the Dansgaard–Oeschger events are largely constrained to ice cores taken from Greenland, if only the most recent 50,000 years from the GISP2 core are examined, the variation of the trigger is ±12% (±2% in the 5 most recent events, whose dates are probably most precise).However the older parts of the GISP2 core do not show this regularity, nor do the same events in the GRIP core.

The comparable climate cyclicity during the Holocene is referred to as Bond events.
