What mass extinction event would that be? Surely not the one that is a computer model of all the species we don't know that are dying?

"Earth Is Not in the Midst of a Sixth Mass Extinction
“As scientists we have a responsibility to be accurate about such comparisons.” "

"At the annual meeting of the Geological Society of America, Smithsonian paleontologist Doug Erwin took the podium to address a ballroom full of geologists on the dynamics of mass extinctions and power grid failures—which, he claimed, unfold in the same way."

"Erwin is one of the world’s experts on the End-Permian mass extinction, an unthinkable volcanic nightmare that nearly ended life on earth 252 million years ago."

"Surely our Anthropocene extinction can confidently take its place next to the juggernauts of deep time—the Ordovician, Devonian, Permian, Triassic and Cretaceous extinctions.

Erwin says no. He thinks it’s junk science.

“Many of those making facile comparisons between the current situation and past mass extinctions don’t have a clue about the difference in the nature of the data, much less how truly awful the mass extinctions recorded in the marine fossil record actually were,” he wrote me in an email. “It is absolutely critical to recognize that I am NOT claiming that humans haven’t done great damage to marine and terrestrial [ecosystems], nor that many extinctions have not occurred and more will certainly occur in the near future. But I do think that as scientists we have a responsibility to be accurate about such comparisons.”

"Passenger pigeons all but serve as the mascot of the “sixth mass extinction,” their extirpation an ecological tragedy on a massive scale, and proof that humans are a geologically destructive force to be reckoned with.

“So then you ask: in a non-archaeological context, how many fossil passenger pigeons are there? How many records are there of fossil passenger pigeons?”

“Not many?” I offered.
 “Two,” he said.
“So here’s an incredibly abundant bird that we wiped out. But if you look in the fossil record, you wouldn’t even know that they were there.” "

The one that your own evidence refers to Lee. Did you read it before copying and pasting?

Yes petal. You do understand the difference between an extinction event and a mass extinction event?

Probably not.

And that goes back to the dawn of Human history. As in NOT a modern phenomenon.

BigP wrote on Apr 19^th, 2019 at 11:33am:


Yes. And extinctions happen without interference from humans.

But back to my previous post seeing as people don't seem to have read the article --

" “So you can ask, ‘Okay, well, how many geographically widespread, abundant, durably skeletonized marine taxa have gone extinct thus far?’ And the answer is, pretty close to zero,” Erwin pointed out. In fact, of the best-assessed groups of modern animals—like stony corals, amphibians, birds and mammals—somewhere between 0 and 1 percent of species have gone extinct in recent human history. By comparison, the hellscape of End-Permian mass extinction claimed upwards of 90 percent of all species on earth."

Poor Barney shows he doesn't know the difference either.

Have you got an idea of scale yet?

You do realise the Anthropocene is not even a real epoch? A term made up by alarmists and rejected.

"Since then, Anthropocene has gained widespread attention amid increasing concerns of global warming, but the International Commission on Stratigraphy, which is the global body charged with naming geological eras, has rejected the proposal."

Poor Will Steffen and Co.

Define "lots".

So 0-1% is a mass extinction event?

That was the original claim.

Nope. You signally failed to read the article about the paleo scientist who insists it is NOT a mass extinction event. You decided to put your own spin on it.

You made the claim. Own it. Don't blame others for your own shortcomings.

Poor freediver shows he doesn't have cognitive function.

That is from the original article which was unquoted. But I did provide a link.

freediver wrote on Apr 19^th, 2019 at 1:13pm:


Where have I said that? I have said it has large error bars.

freediver wrote on Apr 19^th, 2019 at 1:13pm:


Yes. But in the words of the expert it is NOT a mass extinction event. It may never be. What qualifications does Will Steffen hold in paleo data? Or anybody else you want to cite?

freediver wrote on Apr 19^th, 2019 at 1:13pm:


Yes part of the 0-1%.
