The Tragic Truth About The Permian Mass Extinction

The Permian Extinction was one of the most significant events in the history of our planet, one that took place over thousands, or even millions, of years. Our knowledge of what exactly happened is limited, but growing, and there are various plausible theories about how the extinction transpired. What we do know is the global temperatures fluctuated wildly, and many forms of life failed to adapt before dying out. Other lifeforms succeeded in the new environment, and gave rise to the animals and plants that cover our world today (that includes us, dear human viewer!). This is the tragic truth about the Permian mass extinction.

What are your thoughts on the Permian mass extinction?

I feel like I’m back in school...listening to a phenomenal teacher, delivering an incredible lecture...👍🏻 WOW!!

I am a Geophysics major and this is one of my growing specialties. I saw several errors. One was just a matter of clarity: 20 degrees... 1) you needed to specify Celsius or Fahrenheit. The science community typically states the the temperature rose in a range of 10 to 15 degrees C. If you were taking about Celsius, you would be dead wrong. If you were talking about Fahrenheit, the 18 to 27 degrees would be more accurate. 2) Next the one site in Italy as your source of world covering Acid rain would not be accurate. You have it on a localized area. You need multiple sites to say it is a world wide problem. 3) The site in China as your evidence for glaciation is only one site again. This too could be a regional uplift situation due to an active margin. You need multiple sites to say it is a world effecting event. 4) The idea of a Meteor impact as the main cause has been proposed for years and in every instance it gets shot down due to the duration of the event. The duration, some papers say it took as little as 75, 000 years to complete to as much in other research as a million years for the planet to heat up. 5) Lastly, the super continent did not start breaking up until the Triassic Period. Pangea formed during the Permian and start breaking up towards the end of the Triassic.

Great comment about us getting a do-over and getting it right. Political and economic systems on this planet have become untenable. I fear those systems are so entrenched it will require failures which are evident to everyone to remove them. In the process we'll destroy most of the planet and our species. Additionally we've been taught and have learned to be fearful of one another and create psychological boundaries between us and them. Where's the love, the commonality, the mutual cooperation and appreciation? It's in the kids. After all the weapons have been deployed and the survivors realize the tragic error in being their predecessors have made, we'll have to cooperate just to survive. Then we'll learn the value of one another and the folly of egocentrism, and we can create a lasting society with mutual respect and extreme appreciation for this beautiful home we've been given, Mother Earth.

What a great video! As always, wasn't expecting an educatio but, thank you!

This is a very good summary of the current research. Well done.

The Mesozoic also was warmer than today. We are just at a fraction of the greenhouse gases that contribute to the Permian extinction.

Though more complicated, it seems that the massive amounts of methane gas erupting into the atmosphere would have assured a relatively quick extinction of so many living things that it really deserves the title "The Great Dying". Life on earth seems to have come very close to being wiped out.

in my (extremely inexpert) opinion hyper multiplication of methane producing bacteria makes the most sense. Which was made possible by new mutations in the bacteria, and the Siberian traps acidifying the ocean, and the mass die off of other sea life.

he has a terrific way of speaking, not too fast, clear. Not like some, well done

Praying for the survivors of the Permian era. #RIP

[MsArgentana]

about 12 yrs ago a team of geologist suggejted there was a hunge metheor impact in Siberia, so aggressive the the crust collapsed and the earth core leak out. Afterward a global heating killed all ocean life first and than a long dark winter obscured the skies collapsing the I forgot the title of their video....

[billallen]

Drop the AGW rhetoric and I'm interested. Today is nowhere like the Permian extinction and the worst case scenarios from the UN and the bad climate models are also as insignificant.

The obvious is being Hit by Something.
It covers all the bases, large enough or in a softer spot could easily start volcanic and tectonic cycles.
There's always a sudden stop and that's indication of catastrophism

I feel like I’m back in school..: Listening to some teacher, trying to cram Evolution theory down My throat…

[fenrirgg]

Almost everything died, but life is resilient, just give it a few million years 🙁

[Bullweenkle]

I'm curious what National Geographic has to say about it.

[florendarivera]

The use of words as may have been, could have, perhaps, likely, may have been, suggested, estimated, believed, cast doubts on your supposedly claims as facts. A truth must be beyond reasonable doubt. The use of uncertainty words make the whole claim as false. You must know to draw the line between established facts and speculations.

[friendlyone]

If you imagine a rod going from the most likely Permian asteroid impact to the other side, it would be roughly where the massive volcanism happened -- and where the vibrations from the impact would have concentrated. So the asteroid may have triggered the volcanoes.
Rather than global warming -- the CO2 would have helped plants grow -- global cooling, the ice ages mentioned, would be the most logical result.
Rebounding from ice age cycles would have been difficult.
