Global warming led to atmospheric hydrogen sulfide and Permian extinction

95% of all living species disappeared in the Permian extinction. Hydrogen sulfide might have been the cause.

Volcanic eruptions in Siberia 251 million years ago may have started a cascade of events

251,000,000 -- how accurate!

95% of all living species disappeared in the Permian extinction.

But the likes of Janet Reno survived. Where's the justice in nature?

Could be the press release writer's fault.

We had to get rid of those nasty trilobites somehow.

Did you know that Algore discovered hydrogen sulfide? :0)

[YOUGOTIT]

There is no way that a statement like that can be believed. It is a theory, as with the people who believe that the earth turned into a snowball and ended most life or was that another time.

[Buwan]

They had SUVs way back then?

Hydrogen Sulfide: If Siberian gaseous emissions were enough to kill most species, it really ought to lay off the chili.

As the article says: "Finding evidence of green sulfur bacteria would provide evidence for hydrogen sulfide as the cause of the mass extinctions."

It's research in progress, not intended to be believed, but rather examined and weighed.

Let's see if I have this right:

If every country signed the Kyoto Treaty, and we all went back to living in the preindustrial age, nature could still come along and wipe us all out. Is that right?

[snarks_when_bored]

Yep.

This idea that volcanoes near the arctic circle could cause Global Warming ... fascinating ... I wonder ... could it happen again? If we were to find ... let's say ... a chain of volcanoes near Alaska ... that were, you know ... warming the arctic waters ... could that cause Global Warming? Or is this something that only worked 251 million years ago?

There have been many such destructions. They are all believable.

You are being generous. It is not a theory, as theories are based on a lot of testing and observation.

This is a hypothesis, nothing more.

I'm not sure that a link has been posted on FR to the Kyoto Count Up, a page at JunkScience.com. It's pretty interesting:

Those Siberian Trap volcanoes threw truly staggering amounts of ash and chemicals into the atmosphere. If such eruptions happened today, bad stuff could happen again.

[muawiyah]

The volcanic eruptions in Siberia were many times larger than those going on these days. There were also large eruptions in India at a different period of time.

There's a theory that large globules of very hot rock "float" to the surface from time to time, and then break through! Some geologists believe the so-called "super volcanos" sit on top of such globules. Yellowstone is such a place, and if it bubbled through it'd kill us all!

Then there are the rocks that fall from the sky. Some are very small. Some are very large. It happens!

The "snowball" hypothesis left a layer of large gravel in this area. I spent months pulling those rocks out of my lawn when I first bought this house.
