Well, the first one at least is utter BS. Yellowstone erupts on average every 600,000 years or so. There was one in Indonesia about 74,000 years ago. We don't have mass extinctions every 600,000 years, and we didn't have one 74,000 years ago. That eruption in Siberia hundreds of millions of years ago was more than just a supervolcano. Sure, Yellowstone going off could wreck our civilization and kill tens of millions of people, especially in the US, but a mass extinction? No.

Well, Toba was theorized to have led to the extinction of Homo erectus, so it's not exactly a minor problem, but yes, you are correct, there was no mass extinction.

Well, I think we're also confusing the singular event with the reason for their claim of mass extinction. Let@ls not forget that the singular event is just the beginning. It's surviving the mini ice age that'll be the issue.

/I don't think it'll be an extinction event for humans.
// a lot will die

Large igneous provinces/basalt floods =/= "supervolcanoes". The former is effusive, while the latter is popularized to be explosive. There is evidence of explosivity (tuff, pyroclastic rocks, etc) in the Siberian traps (when the traps first erupted, and were dying out), but not remotely enough to indicate "supervolcanoes" in the sense evoked by the article. The Siberian traps were a basalt flood.

Calling the Siberian traps a "supervolcano" is somewhat akin to claiming Kilauea is going to explode and kill everyone on Hawaii. Wrong kind of volcanic activity.

Besides, the popular theory (last I read) is the Wilkes Land impact was what triggered the Siberian traps, and together those two events formed the backbone of the P-Tr extinction. Just like the Chixculub impact is theorized to have triggered the Deccan traps, and together formed the backbone of the K-T extinction. The impact pushed magma into the upper mantle and crust at the antipodal point, forming a plume, consequently a hotspot and then a basalt flood.

Gawker is in and of itself, proof we are headed for mass extinction.

"In recent fossil records, from the past 50,000 years, we can easily see a steep decline in species diversity. The Earth was recently home to many species of so-called megafauna, from mastodons and giant wallabies, to giant sloths, and today they are entirely gone. When you see an entire category of creatures wink out that quickly (in geological time), it suggests more than just typical extinction patterns."

But... but.... climate change is to blame for this, it can`t be something heading our way for 50,000 years!

yeah... I got to that part and basically let the whole article slide back out of my head. Conditioned response to being peddled things I suppose.

None of those was a "sign" of an imminent mass extinction, they were all different ways it could happen, some of which are dubious at best as others have pointed out.
 
2012-10-14 04:47:13 PM
We have a significant advantage that may stop our extinction: we have the power of abstract thought. No other animal has this at all. We will be able to find ways for our ultimate survival. Sure, we may mostly be wiped out, but our best thinkers will find ways to save a few of us.

Given humans intolerance of different points of view, their bigotry, their aggressive nature, their unwillingness, to live with the planet instead of taking it over, and their egos, would it really be so bad from the perspective of the planet if human life were extinguished? Just asking.

He forgot the most likely scenario - one nutjob acquires and uses a nuclear weapon, causing the U.S. to go nuclear against the nutcase and then Russia retaliates with nukes against us because they back said nutjob. Goes untill it is all gone and the bacteria inherit the earth.

This just in: Invasive species are invasive.

I've been thinking on this. Is there really a reason to fight invasive species? Aren't the invasions just evolution in action. If the climate is changing, doesn't it make sense to allow plants and animals that thrive in such climates to be there so that when the others die off there is something there?

I find it fascinating that they claim increasing acidity leads to less calcium, rather than less calcium leading to higher acidity.

chemistry... how does it work?

That article is poorly written but the excess CO2 in the air gets absorbed by the ocean water to produce carbonic acid which in turn dissolves or prevents the building of shells by many animals. You'd better hurry up and go see the Great Barrier Reef before it disappears.

There are political, biological, economic factors that could be extinction starters too.

Some of the vaccine resistant diseases like TB and EBOLA scare the crap out of me and for good reason.

Iran looks like it's trying to start WW3

and the world economy could still collapse.

If you've ever had a bedbug infestation, you'd already know the answer to this is "fark yes"

Just because we cannot stop the natural spread of invasive species doesn't mean we shouldn't try and prevent actively spreading them.

Bedbugs or Republicans. Both are annoying, invasive, blood sucking, extremely hard to eradicate parasites.
