Biggest extinction in history caused by climate-changing meteor
phys.org ^ | 8-1-2013

Posted on 08/05/2013 8:34:44 AM PDT by Renfield

It's well known that the dinosaurs were wiped out 66 million years ago when a meteor hit what is now southern Mexico but evidence is accumulating that the biggest extinction of all, 252.3m years ago, at the end of the Permian period, was also triggered by an impact that changed the climate.

While the idea that an impact caused the Permian extinction has been around for a while, what's been missing is a suitable crater to confirm it. Associate Professor Eric Tohver of the University of Western Australia's School of Earth and Environment believes he has found the impact crater which reveals though the trigger was the same, the details are significantly different.

Last year Dr Tohver redated an impact structure that straddles the border of the states of Mato Grosso and Goiás in Brazil, called the Araguainha crater, to 254.7m years, with a margin of error of plus or minus 2.5m years. Previous estimates had suggested Araguainha was 10m years younger, but Dr Tohver has put it within geological distance of the extinction date....

Well, all we need to do is pass a law banning Climate-Changing Meteors. Problem solved.

And, not to split hairs, but it would be a "Climate Changing Meteorite", but I'd not expect a 'journalist' to know to difference.

Deep time is a lie. That so many supposed conservatives believe this is pathetic.

There is no hard evidence to confirm deep time (millions of years.)

The T-rexes were driving SUVs named “Meteors”

Please step away from the computer, find and destroy any school records you have which falsely indicate that you are capable of any math beyond Obama-level White House drivel, and then apply for an Obamaphone.

I can’t imagine earth is much older than 15,000 years. I won’t get into all the specifics about it right now, but I also think the flood had something to do with mass killing off of animals heh.

he’s right, earth isn’t that old, and everything they use for dating is pure fraud, or pure guesswork. People become vain in their beliefs and refuse to believe the truth. That’s in God’s word.

So in order to be conservative you have to believe in absolute 7 day creation and roughly 10k year old Earth?

I thought conservatism was political view, not religious belief.

From the article:

Dr Tohver believes the explosion of methane released into the atmosphere would have resulted in instant global warming, making things too hot for much of the planet's animal life.

Dr. Tohver neglects to mention that the kinetic energy alone from the impact probably immediately heated the atmosphere to many hundreds of degrees and set most of the planet on fire, in favor of trying to get press by hawking the current media darling - large scale methane release.

I am comfortable as a Conservative who does not know just how long one of God’s days was.

One of his days could be 500,000,000 of our years.

Why are you folks so fixated on time. God exists outside of time and even in this universe it’s flexible and variable.

Or do you oppose Relativity on Biblical grounds too.

redated an impact structure that straddles the border of the states of Mato Grosso and Goiás in Brazil, called the Araguainha crater, to 254.7m years...(due to) ...refinements in geochronological techniques (parentheses mine)

If this were a low-information publication, I might not expect to be enlightened on what these refined geochronological techniques were, specifically. But here we have phys.org glossing over them as though they were somehow now axiomatic. Inquiring minds want to know. How were the old dates obtained, and how were these refined dates obtained? It's kinda important. Meanwhile, I don't think any of these speculations account for massive burials in silt, worldwide. However, the Biblical flood does.

One time I saw Ringo Starr at a bus stop in Gillete, Wyoming.

By the time you see the Meteor, it is too late!
