Did asteroid fracking cause Earth's worst extinction?

EARTH, 255 million years ago. The curtain is falling on a Lost World fantasy. At its peak, our Palaeozoic planet boasted lush forests packed with 30-metre-tall relatives of the tiny club mosses and horsetails that exist today. Giant 2.5-metre-long millipedes scuttled across the ground, while dragonfly-like insects with wing spans of 70 centimetres flitted through the skies. The seas swarmed with scorpion-like creatures over 2 metres long and predatory fish of 10 metres and more.

Some 252 million years ago, this world was gone – transformed by the most traumatic wave of extinctions life on our planet has ever experienced. The mass killing that ended the age of the dinosaurs 65 million years ago grabs all the headlines, but it snuffed out only three-quarters of plant and animal species. The "Great Dying" – more formally known as the Permian-Triassic or end-Permian extinction – did ...

I dare the republicans to frack the arctic methane deposits.

It is likely a asteroid also caused this extinction event...Did a asteroid dropping into a methane deposit make it far worse?

The Permian–Triassic (P–Tr) extinction event, informally known as the Great Dying,[2] was an extinction event that occurred 252.28 Ma (million years) ago,[3] forming the boundary between the Permian and Triassic geologic periods, as well as the Paleozoic and Mesozoic eras. It is the Earth's most severe known extinction event, with up to 96% of all marine species[4] and 70% of terrestrial vertebrate species becoming extinct.[5] It is the only known mass extinction of insects.[6][7] Some 57% of all families and 83% of all genera became extinct. Because so much biodiversity was lost, the recovery of life on Earth took significantly longer than after any other extinction event,[4] possibly up to 10 million years.[8]
Researchers have variously suggested that there were from one to three distinct pulses, or phases, of extinction.[5][9][10][11] There are several proposed mechanisms for the extinctions; the earlier phase was probably due to gradual environmental change, while the latter phase has been argued to be due to a catastrophic event. Suggested mechanisms for the latter include large or multiple bolide impact events, increased volcanism, coal/gas fires and explosions from the Siberian Traps,[12] and sudden release of methane clathrate from the sea floor; gradual changes include sea-level change, anoxia, increasing aridity, and a shift in ocean circulation driven by climate change.

If it's all the same to you I'll wait for the eye-witness documentary on PBS.

its a recipe for disaster but deniers will say its ok because we can exchange fiat money for it

The only way the doomsayers prophecies can be negated is for all of them to go back to the caves and cause nothing to combust. Not for heat. Not for light. Not for cooking. But that would require sincerity....so they fail to show us by example. All they have is words which, fortunately, don't pollute the atmosphere. Well not until they blog them, at which time countless clouds of various gasses are emitted producing the power for their communicators (cell phones, computers, laptops, tablets and even, may God forgive them, iPads).

It gets weirder and weirder around here as the temperatures dare to defy their high priests...
Did you mqke up that fracking segue all by yourself Matthew?

Nope,

PHd's in their field did.

What does "fracking" have to do with a comet striking the earth and wiping out the dinosaurs?

Fracking, as defined by Hydraulic fracturing - Wikipedia, the free encyclopedia wasn't even known that many millions of years ago.

Please explain.

The PT extinction came very close to wiping out vertabrate life on earth. We know for proxy data that the CH4 and CO2 levels were rapidly increased, and that the O2 levels went down to 11% at that time. Also, we know that the Siberian Traps and coal deposits interacted, in fact there is a rather interesting article in the Journal Geology on the native iron created by that interaction. Given the rapid release of GHGs from that interaction, and the fact that there were clathrates in the ocean, the rapid rise in CH4 at that time was probably a result of the clathrates outgassing from the warming of the atmosphere and oceans from the CH4 from the coal-basalt interaction, and the CO2 from the trap eruptions.

Today, we have a very interesting parrellel as we release CO2 into the air from burning the coal for power, and the clathrates are beginning to outgas in the arctic, and have the potential for outgassing along the east coast of north america as the oceans warm. Our descendents are going to live in very interesting times, indeed.

I imagine paleontologists get pretty lonely and weird when they got no bones to show..
But this is just psycho cries for attention here.. These "PhDs" knew EXACTLY what type of audience was gonna actually fall for this fiction....

An asteroid dropping into fractured tectonics.. Yeah -- that's fracking..

 

[CrusaderFrank]

Clearly, the asteroid must have rushed through our atmosphere and converted the O2 into CO2.

How else to account for the devastation?

 

[percysunshine]

Hey! We have a new propaganda term; "asteroid fracking.''

Soon Big Oil will cause an environment transformation that will wipe out all life on earth. Unless we stop it now.

(Ignore the kinetic energy behind the curtain)

Frank -- you better get busy man. The kooks are destroying themselves faster than we can help.. I'm afraid the fun might be over and we'll need a new batch to play with..
