Airbursts/impacts by a fragmented comet or asteroid have been proposed at the Younger Dryas onset (12.80 ± 0.15 ka) based on identification of an assemblage of impact-related proxies, including microspherules, nanodiamonds, and iridium. Distributed across four continents at the Younger Dryas boundary (YDB), spherule peaks have been independently confirmed [...] Cosmic Airbursts – Impacts Leave High Temperature Melt Products at Younger Dryas by George Howard [...]
The Bos is Back! Bos Mum on Mars Update: Coma Just Dust… Elenin: Sliding Spring backing off a bit….. Elenin: Probability of Mars Impact 1-120 or so These media scientists are just too much. Below is bad astronomer Phil Plait validating the Napier Astronomical Model for the Younger Dryas Impact(s) and refuting The Bos’ [...]
As far as disputes over ancient impacts are concerned, the hostility that has greeted evidence for the Chiemgau Impacts is exceeded only by that received by the Younger Dryas Boundary hypothesis. But like the YDB team the Germans have soldiered on and continue to publish more detailed evidence to an increasingly quiet room: [...] But why not France, Bos!? The news release
Independent investigators have failed to confirm the reports of enhanced concentrations of spherules and platinum-group elements in YD boundary sediments. Boslough, Surovell et al., January 30, 2013, Arguments and Evidence Against a Younger Dryas Impact Event
Interhemispheric evidence of a cosmic impact [...] Obviously, this whole “salting” thing from The Bos has got me hopping mad — and for good reason. By implying that the sites were “salted,” The Bos raises the issue of fraud or conspiracy surrounding the modern date he got on his YDB carbon spherule from Gainey, Michigan. But there’s a problem with that [...]
iPaper_embed(’106210252′, ‘key-2i68bycjgm0wdjsmqc1j’, ’600′, ’450′); Working on getting the paper. [Update: Got it above} This appears to be the long hoped for independent, intentional, blind, professional and reproducible confirmation of the original 2007 findings of the Younger Dryas Boundary team. Independent evaluation of conflicting microspherule results from different investigations of the Younger Dryas [...] I came across a well-researched and informative blog today summing up the recent findings and YDB science to date. I was so impressed by Abby Tabor’s post at Science Works Now, “New Evidence for Climate-Changing Cosmic Impact,” I have added a permanent link to her on the side-bar. Tabor it seems was driven — shudder — [...] |
