Creationism and ice core dating

But that is an assumption, a (deistic or atheistic) religious belief. The last paragraph I quoted says the assumption of “absolute uniformity” carries no method by which it can be confirmed…but that simply is not the case.

I do not intend this article as a personal attack on him, of course; it’s just a very good example of a really serious flaw in the creationist paradigm.

Here’s what jumped out at me from his article: that we observe today on average per year [emphasis mine].

If the ice core chronologies can be extended further into the past with accuracy equal to that of the NEEM NS1 core, the effects of volcanic forcing and climate more generally on past civilisations can be improved.

For example, we know that Hekla had two massive eruptions in the past, probably in the 12 century BC, but we do not know exactly when, or what effect they may have had on climate and society.

Figure 1: New ice core timescale of Greenland ice core NEEM NS1 (top) and Antarctica ice cores (bottom), and the effects of their forcing on a climate reconstruction from a small selection of tree rings (middle) (Sigl et al., 2015). For example, 15 of the 16 coldest summers between 500 BC and AD 1000 follow immediately after volcanic events, four of which are found shortly after the largest volcanic events in the record.

It also confirms that the so-called “AD 536 event” was a two-stage event, with two large eruptions, a Northern hemisphere eruption in AD 536, and tropical eruption in AD 540, causing over a decade of poor climate and hardship on human civilisation.

We do not yet know the cause of the so called 4.2 kya event (from 2200-1900 BC), which was a period of altered climate which may have led to the collapse of the Egyptian Old Kingdom, and/or the rise of the Akkadian Empire.
