Russians on the Younger Dryas

At ...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 ... 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 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.

Even more on the YDB event

There is some good stuff to read on the Younger Dryas boundary event at ... a piece written by Rodney Chilton, author and catastrophist, followed  by some excellent comments and terrific links - including a link to a pdf article by Anthony Perratt et al. The comments do come to a kind of conclusion - the jury is out. The impact theory has a major problem - why did temperatures switch suddenly at the end of the YD period, rising very quickly by 10 degrees.

YDB event ... it's still kicking up the dust

At there is a report on a story from Knight Science Journalism Tracker - big media has ignored a PNAS paper on a comet blast even thought the authors worked mainly on grants from the National Science Foundation. The latest paper at PNAS is large, unmissable and has 18 authors yet mainstream media is obsessed with unscientific environmentalist shindigs and political maneoverings at the upcoming Rio bean feast.

Did the Earth turn upside down?

At ... Okanagan is not an Irish surname but a hot dry, and yes, sunny part of Canada very popular with tourists and pensioners. It is a desirable place to live, a huge lake with lots of lakeside properties and ospreys sitting on the telegraph poles. What Okanagan has to do with Velikovsky is anyones guess - but Velikovsky's ideas are alive and kicking in this part of Canada (presumably via a retiree).

Dust levels in the Little Ice Age

At ... Tall Bloke's Talkshop continues to raise some very interesting issues, going to subjects other blogs do not venture, or avoid. In this post, Tim Channon looks at a paper in Quaternary Science Reviews at which was published in volume 30 issue 25-26, in 2011.

YDB boundary bang is still alive and kicking

At SIS we are aware of the Ussello Horizon because of Han Kloosterman who has written and given talks that include mention of Ussello (in his native Netherlands) over many years.

Younger Dryas boundary event again

Dennis Cox at 'A Catastrophe of Comets' - is all about the hypothetical Younger Dryas boundary event - in this instance, in Mexico and California. A core drilling is now underway in a lake in northern California that may shine light on the period, but the main research of the core into lake sediments is designed to find evidence and predict how flora and fauna coped in the past with major abrupt climate change.

Spherules and Impacts

We are assured by the US Geological Society that spherules in black mats have nothing to do with impacts at the Younger Dryas Boundary but a few days later we have this new paper in Nature (April 25th) - see It seems that asteroid/ comet impacts are okay as long as they happened billions of years ago. Jay Melosh focussed on spherules embedded in layers of rock that are said to have been vapourised during an impact collision with the Earth. It expanded as a giant vapour plume that rose into the atmosphere.
