Exploring abrupt climate change induced by comets and asteroids during human history

Greenland icebergs may have triggered Younger Dryas

Hiawatha?

December 7, 2018

This paper from five years ago seems consistent with the Hiawatha Impact Crater. Some 13,000 years ago, as the last Ice Age seemed to lose its cold grip on the Earth, the temperature suddenly plunged again. Up to now, scientists believed that the Younger Dryas cold reversal was caused by great amounts of Canadian meltwater […]

A year later, not a word on Alaska paper in Nature with evidence for repeated cataclysm

December 3, 2018

It’s hard to be cynical enough in this game. I noted today that “Science Communicators,” a recently discussed poorly adapting subspecies, have yet to mention this blockbuster paper in Nature Reports one year ago. Specifically, there is credible preliminary evidence contained by the bucketful that there was a catastrophe prior to the Younger Dryas Impact that […]

The Hiawatha Crater and Global Warming politics

Science communicators give tongue to cats

November 30, 2018

In addition to the recent history of the earth, its animals, and mankind, the Hiawatha Crater discovery may have something else to teach us. The Tusk finds the real-time sociological implications of the crater as fascinating and instructive as the feature itself. I’m obsessed by what the new information reveals about the motivations and perspective […]

Sweatman and Coombs lay odds on Gobekli Tepe and the Younger Dryas comet

November 28, 2018

Martin Sweatman, like The Bos, is a betting man. But in this instance I want his side of the wager. Today Sweatman published a masterpiece of original, rational statical analysis reporting a series of planetary catastrophes as recorded by our elders in ancient symbols in cave art and carved rock. The historic rejection of ancient animal […]

Cosmic impact destroys lost city of the Levant in 1700 BC

November 22, 2018

DENVER — A superheated blast from the skies obliterated cities and farming settlements north of the Dead Sea around 3,700 years ago, preliminary findings suggest. Radiocarbon dating and unearthed minerals that instantly crystallized at high temperatures indicate that a massive airburst caused by a meteor that exploded in the atmosphere instantaneously destroyed civilization in a 25-kilometer-wide […]

Tusk takes Mark Boslough up on Younger Dryas crater probability challenge

November 18, 2018

Who knew? The Bos is a betting man. The recently retired federal scientist, global warming enthusiast, and unsuccessful Republican candidate for the New Mexico State Senate, tweeted his interest in a wager this week concerning the likelihood that the Hiawatha impact in Greenland would have occurred recently enough to cause the Younger Dryas climate crash, […]

Tusk on Hiawatha

A recurring thread as things develop in the short term

November 17, 2018

What a week. The announcement of the Hiawatha Crater is hands down the most important development in the eight year history of the Tusk. Lest I remind you, when your blog’s tagline is “Exploring abrupt climate change induced by comets and asteroids during human history”, and Science publishes a feature article titled: Ice Age Impact: […]

Intrigue at Science

Blockbuster Science story reporter Voosen dishes on Twitter

November 16, 2018

Speaking of journals, this paper spent a long time gestating, passing through more than a dozen reviewers, I believe, who skimmed away the informed speculation. Was that partly due to the possible Younger Dryas tie? Probably. As a coauthor put it, they faced an unfairly high bar. — Paul Voosen (@voooos) November 15, 2018

First Younger Dryas Impact Crater Found: Greenland

In the morning this old world wont be the same

November 14, 2018

Bos Bet… Voosen article in Science Magazine Seven Ages Daily Mail National Geographic BBC NYT MSN Oh, happy day! The Tusk heard about this discovery confidentially in March but the following nine months were characterized by an uncertain confidence this day would truly come. We had published evidence for a decade, and knew a climate […]

Central Europeans confirm Laacher See volcanic eruption preceded cosmic impact at Younger Dryas start

October 4, 2018

See another blockbuster confirmation of the Younger Dryas cosmic impact below. I keep a pretty close eye on our subject but had no idea such intricate, original and thorough work was underway in the Czech Republic. Gunther Kleteschka has appeared on several YDB papers, but has clearly been busy in his own laboratory collecting entirely […]

Wally Broecker says a cosmic impact caused the Younger Dryas

"Although I don’t for a minute believe that this impact did in the mammoths and the Clovis people, I do think that it triggered the YD"    

July 24, 2018

What a significant and pleasing development. Wally Broecker has endorsed a cosmic impact as the cause of the Younger Dryas cold period.  Broecker is a father of modern climate science (and pictured above with the Tusk at my heaviest in 2009). This is more than just another log on the intellectual fire of the Younger Dryas […]

Science News questions science

July 12, 2018

I was about ten when my mom bought a Science News subscription for the Tusk. Week after week the thin, frequent, small format publication filled my desk, and ultimately the floor of my room. The rush of science coverage came so quickly I sometimes felt guilty as a little guy for not reading every article. […]

Chandra Wickramasinghe on the NASA Mars announcement

Panspermia increasingly vindicated

June 7, 2018

The Tusk is honored to maintain a digital acquaintance with distinguished Professor Chandra Wickramasinghe, who in the 1970’s with Sir Fred Hoyle established — and to my mind proved — the theory of Panspermia. We had been corresponding concerning the jaw dropping recent genetic study, when NASA announced today’s press conference. I asked Dr. C […]

A friend of the Comet Research Group\YDB team just sent around an announcement of the following discovery: https://phys.org/news/2018-05-gene-survey-reveals-facets-evolution.html A large-scale genetic comparison has discovered that 90% of […]

Tusk on Seven Ages Podcast

Seven Ages Audio Journal

May 20, 2018

I had a blast last week joining the hosts of my favorite new podcast: Seven Ages Audio Journal. Like the Tusk, veteran podcaster Micah Hanks and his science bros Jason Pentrail and James Waldo attempt the difficult balance between hard science, responsible speculation and perhaps some entertainment. I think they recognized me as a “fellow […]

An Overview from Dr. Martin Sweatman

April 22, 2018

A friend sent me this paper from Dr. Martin Sweatman who gained international notoriety last year with a previous journal article linking the world’s most ancient temple, Gobekli Tepe in Turkey, with the Younger Dryas Impact. The Tusk enjoyed that paper and was pleased to see Sweatman make a second contribution to our field; this […]

Black Mat in Turkey

Asia

March 23, 2018

This week Rick Firestone shared a little known 2009 paper with the Tusk and some others. I was unaware of it and enjoyed reading it. The authors find a unique spike in fire at Akgol, Turkey ~13,000 years ago which they attribute to a horrendous inferno in a marsh, of all places. They cite Firestone […]
