Settled Science: Asteroid Ended Dinosaurs

From an unquestioning Reuters:

It’s official: An asteroid wiped out the dinosaurs

By Kate Kelland, Health And Science Correspondent Thu Mar 4

LONDON (Reuters) – A giant asteroid smashing into Earth is the only plausible explanation for the extinction of the dinosaurs, a global scientific team said on Thursday, hoping to settle a row that has divided experts for decades.

A panel of 41 scientists from across the world reviewed 20 years’ worth of research to try to confirm the cause of the so-called Cretaceous-Tertiary (KT) extinction, which created a "hellish environment" around 65 million years ago and wiped out more than half of all species on the planet

The new study, conducted by scientists from Europe, the United States, Mexico, Canada and Japan and published in the journal Science, found that a 15-kilometre (9 miles) wide asteroid slamming into Earth at Chicxulub in what is now Mexico was the culprit.

"We now have great confidence that an asteroid was the cause of the KT extinction. This triggered large-scale fires, earthquakes measuring more than 10 on the Richter scale, and continental landslides, which created tsunamis," said Joanna Morgan of Imperial College London, a co-author of the review.

The asteroid is thought to have hit Earth with a force a billion times more powerful than the atomic bomb at Hiroshima.

Morgan said the "final nail in the coffin for the dinosaurs" came when blasted material flew into the atmosphere, shrouding the planet in darkness, causing a global winter and "killing off many species that couldn’t adapt to this hellish environment."

Scientists working on the study analyzed the work of paleontologists, geochemists, climate modelers, geophysicists and sedimentologists who have been collecting evidence about the KT extinction over the last 20 years.

Geological records show the event that triggered the dinosaurs’ demise rapidly destroyed marine and land ecosystems, they said, and the asteroid hit "is the only plausible explanation for this."

Peter Schulte of the University of Erlangen in Germany, a lead author on the study, said fossil records clearly show a mass extinction about 65.5 million years ago — a time now known as the K-Pg boundary…

Gareth Collins, another co-author from Imperial College, said the asteroid impact created a "hellish day" that signaled the end of the 160-million-year reign of the dinosaurs, but also turned out to be a great day for mammals.

"The KT extinction was a pivotal moment in Earth’s history, which ultimately paved the way for humans to become the dominant species on Earth," he wrote in a commentary on the study.

This is all well and good, but we won’t be completely convinced until those all-knowing scientists at the United Nations officially weigh in.

Still, you have to wonder what “new great day” for some other species are we blocking by not destroying the world with nuclear weapons or man-made global warming?

It sounds like oppression to us.

    I would have agreed with the supposition but now that it’s “settled” I begin to wonder….

      I would tend to agree, however, there is no regime change to be ushered in by the Asteroid theory. That is unique to the religion of global warming and socialism.

    “A panel of 41 scientists ”

    Science by committee.

    Governance by fiat.

    Bizarro world to the bizarroth power.

  3. BannedbytheTaliban says:

    Like all articles in the MSM of scientific content, this article shows no evidence/data what-so-ever. The only thing reported is peoples’ interpretation and several iterations of “no other possible explanation.” Of course if they gave some actual data then the casual reader may be able to form their own opinions and they just couldn’t have that. Conformity of opinion above all else, sadly socialism is all too prevalent in the scientific community.

    Here is a link to the actual article if anybody is interested:

    I get it now, asteroids cause global warming.

    This week.

    Next week it will be something else that is “official” and “settled science”, that wiped out the dinosaurs.

    It’s like the old weather saw. Don’t like the weather (settled science)? Wait a few minutes…it will change.

    Question…If this asteroid was so selective on which creatures it knocked off…How? Why? Where did they live that only half the world’s living creatures died and the other half lived?

    And, prey tell where are all these remains?

    So a delicate little mammal or say…humingbird…was somehow immune?

    What about the elephants? Alligators and lizards. And a host of other “modern dinosaurs”.

    Aren’t we always being told how they are really present day dinosaurs? How did they manage to make it past the dinosaur specific killing asteroid? I have a million more questions…but I’m sure with a little double talk and science fiction it can all be easily explained.

    Sorry…just ain’t convinced.
