Catastrophism news

Younger Dryas watershed

This is really basic geology but I'm placing it under the catastrophism banner as it has a bearing on the recent hypothesis of a comet impact at the Younger Dryas boundary - now, in light of a paper by Bill Napier, regarded as the Earth encountering a Taurid stream of material rather than an impact event as such. At http://geology.gsapubs.org/content/38/4/383.short?rss=1&amp%3bssource=mfr ... 'What Caused the Younger Dryas Cold Event?' doi:10.1130/focus042012.1v38no4page383-4 and actually explores the route of the meltwater during the Younger Dryas.

The Mystery Interval

At http://geology.gsapubs.org/content/early/2012/08/08/G33279.1.abstract ... is an abstract of a paper published August 2012 in Geology journal, 'Seasonal Laurentide Ice Sheet melting during the Mystery Interval, 17.5-14.5ka' and begins by saying the last deglaciation (the end of the last Ice Age) was interrupted by two stadials (cold episodes).

a 1560s lightning bolt

At http://cosmictusk.com/kobres-on-16th-century-se-american-impacts/ ... Bob Kobres reports on some interesting events. For example, the town of Thunderbolt in Georgia was named from the translation of a native word for the area when an unusual lightning bolt had formed a spring which tasted of iron and sulphur.

Droughts in Egypt

This is at http://phys.org/print264333845.html ... evidence of the end of Old Kingdom drought as recorded in the Ipuwer Papyrus (first intermediate period) has been found in pollen and charcoal preserved in buried sediments from the Nile delta. Several major drought episodes have been found, corresponding not just to low Nile levels but to precise setbacks in the civilisation of Egypt. The paper is published in the journal Geology (July, 2012) and the sediment core goes back to around 5000BC.

Elephants eating habits

This can be found at www.phenomenica.com/2012/07/african-elephants-are-picky-eaters/ ... which is interesting as the same may have applied to mammoths. Elephants don't eat just anything but selectively choose what species they consume and which woody parts they find palatable. Elephants prefer the bark, stem and roots of plants and shrubs, or trees, rather than the foliage or fruit. Where might that leave the eating habits of mammoths in a frozen world?

Chinese riddle

In Shorter Science and Civilisation in China:2, an abridgement by Colin A Roman of Joseph Needham's original 1981 text, we have on page 84 ...

'In ancient times Kung Kung (one of the legendary rebels) strove with Chuan Hsi (one of the legendary emperors) for the Empire.

Angered he smote the Unrotating Mountain, Heavens pillars broke, the bounds with Earth were ruptured, Heaven leaned over to the north west, hence the Sun, Moon, stars and planets shifted, and Earth became empty to the south east'

The Younger Dryas boundar event - the dispute in a nutshell

At http://blog.mysciencework.com/en/2012/06/19/new-evidence-for-climate-cha... .... is an overview of the YDB event hypothesis and its detractors - and the nature of the dispute between those who favour a cosmic impact of some kind and those who are opposed to such an idea, preferring the ocean circulation hypothesis. Note that the idea of solar activity, or a downsizing of solar activity, is not part of the debate - here, at least.

Russians on the Younger Dryas

At http://elpub.wdcb.ru/journals/rjes/v09/2007ES000250/2.shtml ...The Russian Journal of Earth Sciences (2007) had an article, 'Long term solar activity variations in the Pleistocene and their connection with abrupt climate change' ... it is interesting that as the role of co2 is increasingly seen to be much less potent than the doomsayers alleged that some scientists are looking to the Sun to explain the dips and peaks in temperature as apparent from ocean sediment cores and isotopes in ice cores etc.

The Younger Dryas Boundary event ... can it survive?

At http://wattsupwiththat.com/2012/06/19/the-intriguing-problem-of-the-youn... ... there is an excellent posting by Don Easterbrook, a geologist from Western Washington University, on the Younger Dryas event, the periods preceding and following it, and temperature fluctuations within it. A lot of this is actually a bit of an eye opener - and the latest research. As the years have progressed a considerable amount of data has accumulated on glacial advance and retreat, especially when it comes to Scandinavia where the research has been intense.

Mammoth die-off

At www.phenomenica.com/2012/06/mammoth-graveyard-uncovered-in-serbia/ is just the latest report on the discovery of mammoth remains from around the northern hemisphere - this time in Serbia. They are regularly encountered in the UK during construction work - and just as regularly not reported to the authorities. The same thing goes on everywhere. Geologists and Paleontologists poking around slows down commercial enterprise, whether a housing scheme or major road building. Only the odd discovery is reported to the local museum, council, or relevant government department.
