Let me guess, this is the same as the article submitted last week that said somewhere in Russia a bunch of coal burned out and sent fly ash into the atmosphere and caused a mass extinction event.

*clicks*

"But what originally triggered the spike in carbon dioxide? The leading theory among geologists and paleontologists has to do with widespread, long-lasting volcanic eruptions from the Siberian Traps, a region of Russia whose steplike hills are a result of repeated eruptions of magma."

Ding ding ding! Old news is so exciting!

At this rate we're going to need a "FARK Volcano Thread Bingo" card. Yeah, yeah, Yellowstone Supervolcano, Indonesia, we-need-global-warming-to-fight-the-particle-induced-Ice-Age, EVERYBODY PANIC, tsunami from the collapse of the Canaries.... What the hell, let's throw in Time Cube as the free space.

The big deal here isn't the link to the Siberian Traps eruptions, it's the rate at which the extinction pulse occurred. Prior to the last year, the general consensus was that the end-Permian event may have included several pulses that were a few million years apart. Now, it looks like the big event happened almost instantaneously (geologically speaking).

This is a big shift in interpretation, regardless of what all the political whack-jobs are blabbering on about.

This. The connection between the Siberian Traps and the late Permian extinction has been known for decades. All this article does is report on a PNAS paper that provides more detail on the timeline.

There is a second part to this. And a third.
The theory goes, the Siberian Traps caused the big extinction event in the Permian.
The hot spot that caused the Siberian Traps went silent and moved relatively speaking to the spot under India, erupting again, making the Deccan Traps, which killed off the dinosaurs.
That's Two, TWO Extinction Events by the same feature ah, ah, ah [/CountVanCount]
Observations and speculation put that same hot spot halfway to Africa around the Seychelles. Others dismiss that, saying we would have seen something in the plate boundary between Africa and India by now if that was the case.  The Deccan Traps event doesn't precisely fit the timing for the K/T extinction, but does fit CAGW theory, as does the Siberian Traps.

lolwut?

The generally accepted theory is that thee Chicxulub impact had the majority effect on the K-T extinction. There were other events that may have exacerbated the effect is all.
 
2014-02-11 10:00:39 AM  
I've always kind of hoped that scientists would discover that the Permian extinction was actually due Wilkes Land impact...but it's looking more and more that the Siberian Traps were the likely culprit.  Call me a sucker for the classic and more cliche' meteorite stories.

It is a weird corrilation between metrior strikes and large volcanization events.  Why not both?

That's one of the postulations regarding large impacts, that they could trigger volcanic events on the opposite side of the Earth. There just isn't a lot of evidence to support or overturn it yet.

While the current consensus is that the Chicxulub event did cause the K-Pg extinction (aka the K-T), there is credible evidence to support the Deccan traps theory. In particular the fact that most cretaceous fossils are found just below the iridium layer (believed to be the signature of the Chicxulub impact). This would indicate that the extinction begun before the impact.

Personally I believe both the Deccan traps and the Chicxulub impact were contributing factors.

WHY NOT BOTH?
Plate reconstructions for the Permian-Triassic boundary place the putative crater directly antipodal to the Siberian Traps,

Impact set the volcanos off
together they screwed with everything

cracks me up when I read explanations that imply that there is only one answer, when multiple causes are probable

both of these events leading to warming oceans also probably caused methane hydrates to melt further screwing with the big picture

Which is basically what I said. The current evidence supports the impact as the main contributor. He was using CAGW to imply that there is some sort of conspiracy to say that it was only the Deccan traps.

I think the "majority effect" is still under debate. If the cretaceous fossils were at or just above the iridium layer, I think it would be clear that the Chicxulub impact was the major cause. Given that they are below the iridium layer however seems to support the Deccan traps (or some other event) as the major cause, with Chicxulub being the final "nail in the coffin".

I graduated college before the  Alvarez hypothesis was first published.  Imagine if you will other hypothesises postulated before theAlvarez hypothesis was put forth.
As I recall, the volume of the Deccan Traps is sufficient, but the timing is only slightly off.

Cooling. Impacts and eruptions block the sun, decrease surface/ocean temps, and tear-up the food chains.

Kind of like those common ancestor folks. I imagine that there were multiple occasions of abiogenesis, but only one proved very successful, dominated, and subsequently wiped out its competitors. I doubt we will ever find fossil evidence of three billion year old single cell organisms, but that doesn't mean life didn't take many forms when it first manifested.

Obviously this is flawed because earth is 6,000 years old.

Couldn't there be other reasons for the fossils showing up below the layer but not at or above?
