YD impact debate update

At http://cosmictusk.com we have a couple of stories on what is an ongoing debate - have scientists found evidence of a cosmic connection with the advent of the Younger Dryas or can the anomalies be explained by terrestrial based events. There is a critique of a paper by Pinter and Scott that claims carbon spherules of the type found in the black mat layer can also be found in forest fire incidents and therefore do not prove a cosmic origin for them.

Anasazi

At www.sciencedaily.com/releases/2010/06/100609122842.htm June 10th ... a connection has been made between La Nina sea surface temperatures in the central Pacific Ocean and drought in western Europe and the SW region of North America and Mexico, in a paper published by Geophysical Research Letters. El Nino's affect weather systems, it is thought - and therefore so too must La Nina's.

Target: Earth

Member John Plaxton recommends Target: Earth, by Allen O Kelly and Frank Dachille, Pensacola Engraving Co: 1953 a book that was published at around the time of Velikovsky. It appears to be unavailable through Amazon so any member with more information, or a brief write-up of the contents, is welcome to get in touch via news [at] sis-group [dot] org [dot] uk

Cosmic Tusk update

At www.cosmictusk.com/deep-time-impact-induced-volcanism-a-colloquy is an exchange between Hermann Burchard and Han Kloosterman - with George Howard in the middle. Han calls Veilkovsky a 'scholar' rather than a 'scientist' and physicist Peter Warlow, a Velikovskian who came up with the tippetop theory, a valid model. Warlow was supposedly debunked by Slabinski and his paper was uncritically accepted - especially by Leroy Ellenberger (known to both Burchard and Kloosterman).

Comet Disintegration

At www.cosmictusk.com 'Smoke linked to Gun: Napier upheld by Nesvorny and Jenniskens on the Zodiacal Cloud' - George Howard has a pop at Richard Kerr of Science Magazine. The Zodiacal cloud, the consensus theory said, originated in colliding asteroids from the asteroid belt. Now Kerr, after reading Nesvorny and Jenniskens accepts an origin in comets - but blatantly avoids mentioning the Napier hypothesis and therefore ignores the implications. This seems to have riled George.

Ignimbrites

At http://sites.google.com/site/dragonstormproject/ is a blog devoted to a comet firestorm that contributed to the YD cooling event and faunal extinctions 13,000 years ago. He especially targets what is known as Ignimbrite geological formations found in the Chihuahua desert of northern Mexico - which he calls 'fire cloud rock'. They have the look of wet fast flowing concrete or lumpy mud in satellite images.

Zodiacal Glow

At www.physorg.com/print190569543.html ... Nesvorny and Jennisken in The Astrophysical Journal attribute the glow that straddles the night time zodiac in the eastern sky as sunlight scattered on dust particles - from  comets. More than 85 per cent of the dust, they say, originated from short period comets - not asteroids. In addition, snow in Antarctica is laced with micro-meteorites and 80 to 90 per cent of this comes from the same source.

YD impact; increasingly looks unlikely - or does it?

Starting on a positive note but with no idea if he is describing reality or not, we may begin with http://craterhunter.wordpress.com April 10th and a post with the title (see right hand menu on web page) 'The North East impact zone and the destruction of the Laurentide ice sheet' ...

Accessible Articles via links on Cosmic Tusk

At www.cosmictusk.com April 9th ... there is an article on the YD boundary event and it's impact on Arizona, published in Proceedings of the National Academy of Sciences. Many sites in Arizona have evidence of the Clovis culture which apparently thrived in the centuries immediately before the Younger Dryas period. A raft of large animals became extinct at the boundary, the dividing line being a thin black layer in the geology (they are below but not above the black layer).

Morrison locking horns on the Tusk

Over at George Howard's site, www.cosmictusk.com April 8th there is a response by Burchard to NASA scientist David Morrison who is critical of the YD boundary event as postulated by Firestone and West et al. With the WISE mission ongoing upstairs this might not be the wisest of moments to claim there is no evidence of impacts or inter-actions between space and the atmosphere of the earth as recently as 12,000 years ago. However, Morrison is not in that mould.
