If you seek an indication that something is terribly wrong with science look no further. In 2012 brave citizen of Miami Cory Boehne noted that just south of the Port of Miami ship channel, less than two miles from downtown Miami Beach in 30′ of water, was the unmistakable signature of a cosmic collision: A […]

…the impactor would have encountered the atmosphere at velocities of approximately 20-50 km/s, and the released energy of the airburst would have been comparable to or greater than any known nuclear explosion. From Wikipedia: The structure was identified on the basis of Landsat imagery in 1985.[2] It is located between the Manupari and Madidi Rivers.[3] […]

I’ve previously posted my frustration with the silence concerning the presumably on-going research to characterize and date this extraordinarily young impact crater in Greenland. I’ll put that rant aside, and repeat the establishment line here (unchanged since the discovery): The cosmic impact crater creating, climate changing, 5-mile deep, 19-mile wide, bowl of molten rock is somewhere […]

As regulars know, this is the 2nd communication this week from living scientific martyr Dr. Chanda Wickramasinghe to the Tusk, and this one is perhaps the more pressing. Chandra’s note below, shared first on the Tusk, is to the prestigious medical journal The Lancet and a technical communication concerning the increasingly global scourge of Coronavirus. […]

The Tusk has a flip-side fascination to my obsession with cosmic impact and extinctions: Life on earth and how it got here. Looking into the life story makes a nice yen to the yang of the death story. So I have been fortunate over the years to develop a digital acquaintance and enjoy occasional correspondence […]

I made a bad mistake on a great podcast Friday night. I accused Andrew Scott and a gaggle of other Younger Dryas Impact critics of sub-par work in their 2010 paper investigating carbon spherules, they DID use Transmission Electron Microscopes, and I flat out said they used only Optical Microscopes. Thankfully, since I brought the […]

Fourteen months ago the Tusk could not have been happier. Science Magazine not only addressed the Younger Dryas Hypothesis for the first time in a decade, but did so in a lavish, well-written article. The article accompanied the announcement of what seemed could be the long sought ‘smoking gun’ of the YDIH: A massive crater […]

You would think the Tusk and Marc Young’s effort to develop an easily accessible, comprehensive bibliography of all peer-reviewed literature concerning the Younger Dryas Impact Hypothesis would prove a pretty uncontroversial matter. Indeed the effort might be appreciated by anyone interested in the subject, regardless of their support for the published evidence of global cataclysm […]

Well, maybe it’s not really a “thang,” yet. But the Tusk is having some popular fun on Twitter tweeting photographs of the iconic, but relatively unknown, Younger Dryas Black Mat. I think many people interested in our subject have some sense that a clearly visible, multi-continent-wide, destruction layer exists, but many others certainly do not […]

Point Counter Point

The science publishing and peer-review process gets a lot of grief, often for good reason. Many fruitful areas of paradigm changing research languish outside the major journals and never pass from the gatekeepers to the printing press. But thankfully the YDIH, despite the controversy and “robust” debate, appears regularly in the world’s top earth science […]

It is fun to see curious and smart people across the planet learn of our theory, and add content to the internet that allows rational consideration of the Younger Dryas Impact Hypothesis. In a well produced effort, this cat provides some informed science communication. Despite disagreeing with the Tusk on a point or two, it […]

I can’t quite recall where I first heard of Summer Praetorious, but she is a respected professional in our area of inquiry. So I was intrigued today to see Summer post a pic of a collection of rather odd materials from a Younger Dryas marine core sample. Mighty cool. Cheers to Summer for sharing the […]

Sharma, 2013 This week is “abstract reveal” week for the enormous annual conference of the American Geophysical Union (AGU) held each December (See Tusk at 2009 AGU). So each year around this time I search the AGU website for any coming presentations concerning the Younger Dryas and cosmic impact. Fall Meeting 2019 San Fran turned […]

Tireless Aussie Marc Young has done it again. During his summer holiday Marc has managed to link every YDIH peer-reviewed journal article directly from the bibliography spreadsheet. My idea to have a slick “accordion file” of all the papers at the bottom of the page was simply ahead of its time, and this is a […]

The Cosmic Tusk has had the good fortune to join several podcasts in the last couple of years to discuss the Younger Dryas Impact Hypothesis. I am a HUGE podcast fan, and unlike TV, narrow subject fiends like myself stand a chance to get on the air. The experience of speaking on our subject, instead […]

Welcome to the permanent host page for the most comprehensive bibliography of scientific literature concerning the Younger Dryas Impact Hypothesis. The bibliography was compiled in a collaboration between the Tusk and Mr. Marc Young, an Australian Archaeology & Enviro-Sci undergrad who performed most of the meticulous work. Significantly, this page will include not only the […]
