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.

Younger Dryas Boundary event debunked once again

At ... a new study, by the US Geological Survey, claims it has found evidence that elevated levels or iridium, magnetic spherules and titanomagnetic grains, usually thought to be impact markers, have a more than likely terrestrial origin. No comet broke up over North America, they say, but we might ask, is this the kind of evidence we might expect of uniformitarian orthodoxy repudiating the YDB event mainly as it does not equate with their belief system as regards the past history of the Earth, or is this serious scientific scepticism.

Latest on the Younger Dryas boundary event

In Pleistocene Coalition News 4:2 April, 2012, George Howard has a piece on the Carolina Bays and the YDB event. The Bays consist of tens of thousands of shallow, symetrical, elliptical depressions. Some have become ponds and lakes but most are just boggy or have dried out and are common to the eastern seaboard zone of the US but also occur as far west as Nebraska and Kansas. He describes how he first encountered them - as a young researcher working for a local politician who was fascinated by them.

Did volcanic activity trigger the Little Ice Age?

This post can be found at is taken from the blog of Roger Pielke Sr and refers to a paper in the Geophysical Review Letters 39, L02708, doi:10.1029/2011 GL050168 by Miller et al. Miller and pals claim a half century of volcanism initiated a chill lasting half a millennium - is this possible?

Carolina Bays (and similar geological features)

At ... Michael Davias is placing a date around 40,000 years ago on the Carolina Bay formation. George Howard makes the point that no single explanation as yet accounts for all the observed characteristics of the Bays.
