Rm section

I tooko this out:

While much of the most blatant evidence of the Piora Oscillation relates to cold and flooding, the effects of the period were multifarious, and included a few centuries of general drought in East Africa.^[1]

The quoted ref [1] says 4000 BP, which doesn't fit in with the claimed PO timing, and certainly can't be *caused* by the PO William M. Connolley (talk) 12:00, 9 October 2009 (UTC)[reply]

Wrong times

Note that the 5300 cal. BP, given in Magny/Haas, correspond to 3350 cal. BC, and thus contradict the former here given time span. I corrected it to more up-to-date views.2A02:8108:9640:AC3:5019:39F1:6412:EAD0 (talk) 06:14, 30 August 2020 (UTC)[reply]

Temperature graph (of Rhode)

I removed the graph because it is by far to rough as being of service to detect a relation to the alleged Piora oscillation.2A02:8108:9640:AC3:7127:2BCA:7529:7DB7 (talk) 10:06, 17 February 2022 (UTC)[reply]

Hair-rasing phantasy

I deleted the phantasy sentence "Other authorities associate the Piora Oscillation with other comparable events, like the 8.2 kiloyear event, that recur in climate history, as part of a larger 1500-year climate cycle." with no "other authorities" named.2A02:8108:9640:AC3:7127:2BCA:7529:7DB7 (talk) 10:10, 17 February 2022 (UTC)[reply]

NO AGREEMENT about a "Piora Oscillation"

The whole article is pure self-contradicting nonsense, given the self-contradicting sources. I know all literature from alpine researchers and not two of them agree unless copied from each other. Most trustworthy is Maligny, because around -3'350 and ONLY there, a sharp decline in temperatures appears in many climatic proxies, as e.g., Greenland icecores, Alpine treelines, or tree-Ring studies. See my graph at Holocen climate.HJJHolm (talk) 15:31, 2 March 2024 (UTC)[reply]

Miscitation

The cited - an higly reliable -"Magny, Michel; Haas, Jean Nicolas (2004). 'A major widespread climatic change around 5300 cal. yr BP at the time of the Alpine Iceman' " does in no way support the times originally noted here. Instead Magny agrees with the graph of Hans J. Holm of the holocene climate in the North-Atlantic-Realm (see Holocen in both the alpine treeline and the treering widths. HJJHolm (talk) 08:51, 22 September 2024 (UTC)[reply]
