If humans continue to pump greenhouse gases at our current rate, “we have no reason to think it wouldn’t cause a similar type of extinction," said Curtis Deutsch, a UW professor and author of the research.
More than two-thirds of life on earth died off some 252 million years ago, in the largest mass extinction event in Earth’s history.
Researchers have long suspected that volcanic eruptions triggered “the Great Dying,” as the end of the Permian geologic period is sometimes called, but exactly how so many creatures died has been something of a mystery.
Now scientists at the University of Washington and Stanford believe their models reveal how so many animals were killed, and they see frightening parallels in the path our planet is on today.
Models of the effects of volcanic greenhouse-gas releases showed the earth warming dramatically and oxygen disappearing from its oceans, leaving many marine animals unable to breathe.
The researchers tested the model’s results against fossil-record patterns from the time of the extinction and found they correlated closely.
“The study tells us what’s at the end of the road if we let climate [change] keep going. The further we go, the more species we’re likely to lose,” Deutsch said. “That’s frightening. The loss of species is irreversible.”

Earth is going to get hit by a Comet again?
Maybe it will land on Seattle and we can be done with these nuts.
They’re acknowledging that humans were not responsible.
The buffoonery that passes for a university professor ‘pseudo-scientist’ these days seems to be willing to overlook a lot of things to push an agenda based on fiction and models. Suhprize suhprize..
Agenda Uber Alles.
“we have no reason to think it wouldn’t cause a similar type of extinction,”
These “scientists” have given up on anything actually scientific.
Yes, frightening perfect parallels. I look out my window right now and see animals falling dead to the ground, unable to breath. The oceans are full of asphyxiated marine life bobbing on the surface as far as the eye can see.
Oh wait, none of that is happening. Yet, it's exactly the same.
Was it cause by cave men?
Wow, so much to mock in this anti-science propaganda.
1. They claim rising CO2 caused an extinction event and it was due to natural causes, but rising CO2 now is not. And the science that supports this is??
2. Use of non-validated models? Does not get more anti-science than this nonsense. Use of non-validated models equals no information about anything regardless of what the model says.
3. And the definite science on extinction events is? Oh, they are still theories or hypotheses? So we have a hypothesis, an unvalidated model, unexplained naturally occurring CO2 equals humans are baaaddd.
The Rat party hates STEM, is anti-science and anti-religion, but is pro-witch and pro-communist. Both of which are provable nonsense.
The conditions are that the Earth is hurtling though space and there are asteroids and comets floating around in our path.
Where do they get these idiots? How much formal education do you need to get that stupid?
So how long is this gonna take? Will we all die a quick death, a slow death or will we adapt?
Me I figure I’ll just adjust my thermostat as needed.
And unicorns fly out of Bill Nye's butt.
Yeah, but we have trouble getting the numbers correct after a natural disaster. So exactly how does he come up with this claim? Also, man was not the cause of that occurrence, if it actually happened, and won't be if his warning proves correct. Needless to say, I am highly skeptical of his "models" just as I am of all the other "models" that have proven themselves to be as wrong as can be. Yawn.
Redistribution of Wealth is the thing that will save the Earth and everything on it ,LOL
Who knows; they might yet discover a giant SUV driven by sapient Tyrannosaurus rexes.
Aye, it's fooked that we are.
Let's have a drink and grill up all the meat then.
Well, before all that happened you had to see the SUV's driving around during the Permian.
Poor animals their feet could reach the pedals but their arms were to short to reach the steering wheels. The rest is history.
“Grad students, today’s assignment is to design a model for global extinction using only today’s temperature, humidity and pressure as inputs. Then retroactively correlate it to yield a similar extinction climate 252 million years ago.”
