Great Dying’: Biggest ever mass extinction triggered by global warming leaving animals unable to bre

Holy crap! OK now I'm scared and I'm getting on the AGW bandwagon!

"Study highlights potential for similar event resulting from man-made climate change, scientists say"
"Lessons from the Great Dying have major implications for the fate of today’s warming world, say the US scientists."
"If greenhouse gas emissions continue unchecked, ocean warming could reach 20 per cent of the level experienced in the late Permian by 2100, they point out.

By the year 2300 it could reach between 35 and 50 per cent of the Great Dying extreme."

Oh wait. Once you dig into this and discount the sensational headline and opening comments it's just more BS meant to scare you into thinking the "right way" The reality is we couldn't duplicate this event if we tried. What this does prove is the earth itself is capable of violent extremes that have in the past led to catastrophic climate events and it will again and will overwhelm in tiny contribution man has made to climate.

"The new study published in the Scientific Reports journal, claims the extinction was triggered by the release of more than 200 billion gallons of molten lava over a stretch of land called the Siberian Traps."

"Scientists found spikes in the amount of nickel – an element formed by volcanic magma – in rocks dating from the period also known as the Great Permian Extinction in countries around the globe, including China, Israel and Hungary."
"At the same time, explosive interactions of the magma with older coal deposits could have released large amounts of carbon dioxide and methane, two greenhouse gases, which would explain the intense global warming recorded in the oceans and on land at the time of the mass extinctions.


"But it was the huge volume of sulphur dioxide and carbon dioxide released into the atmosphere that caused the planet to become close to uninhabitable. First Earth cooled by a few degrees before warming it by about 14 degrees Fahrenheit and triggering acid rain.

Michael Rampino, New York University geologist and the paper’s senior author, said: “The Siberian volcanic eruptions and related massive intrusions of nickel-rich magmas into the Earth’s crust apparently emitted nickel-rich volatiles into the atmosphere, where they were distributed globally."

"The catastrophic rise in seawater acidity is thought to have been caused by the continual eruption of super-volcanoes, releasing vast amounts of carbon dioxide"

The Great Dying: Earth's biggest mass extinction 'caused by Siberian volcanoes' 250 million years ago

That is the actual article title and has nothing to do with AGW....what was your point?

 

Study highlights potential for similar event resulting from man-made climate change, scientists say"

Get it now?

 

I have been exposed to other presentations of this event and it is pretty good evidence that CO2 does, in fact , cause the temperature of the earth to rise over time.

 

Though CO2 certainly played a role the Sulfur Dioxide likely played a larger one.

 

Yup...I get it now...Hyperbolic BS.

 

A role in the acid rain but not so much in the greenhouse effect. SO2 is not a greenhouse gas but a precursor to sulfuric acid .

 

And when vegetation dies en mass CO2 becomes a larger problem and herbivores starve....which leads to dead carnivores.

 

Yes it is hyperbolic BS that this past event has any relation to man's C02 contribution today and that's what I was pointing out.

 

Lot's of folks say that the CO2/ΔºC for the Permian Epoch proves that CO2 makes temps. go up, but maybe y'all can show me what I'm having trouble finding. Here's the record (from Geologic Global Climate Changes:


What we got is that before the Permian Epoch CO2 levels had been way higher than they are today and temperatures fell. During the Permian Epoch CO2 fell more --and then the world heated up 10ºC. This all ended and cooling began only when CO2 finally rose.

Are we talking about the same Permian Epoch? Someone explain why this whole story isn't crazy. Something else is the fact that the Permian 10ºC temp rise took place over 45 million years; that's 0.2 millionths of a degree per year instead of the current 0.005ºC per year rise that folks are pointing to now.

 

If you placed your hand on a hot stove two years ago it has no relation to today. But if the stove is hot you will still get burnt. A gas guage on a truck has no effect on how much gas is in your tank. You can blame the guage but the truck wont go until you put gas in the tank. Co2 makes it warmer and the only solution is to reduce the Co2 in the atmosphere. You can blame the guage if you like...but.

 

So??

Don't confuse poor journalism with good science

 

What was the solar output during this period? What was the earths position within the Milankovitch cycles? What was the volcanic activity like? How much limestone was exposed by geologic events? What was the albedo of the planet?

BTW The citations from that AstroTurf site are about 16 years out of dat

 

How do you know?

I though the current stance was that the current change was all natural and if so does it not follow that what has happened in the past could happen now?

https://phys.org/news/2013-03-link-co2-mass-extinctions-species.html

 

History is always important to put current events into context. To follow through on your gas guage parable and history dismissal, your gas guage says empty but history shows it says empty when half full so there is no need to panic and look for the first overpriced gas station to fill up.

 

As I said it could happen now and likely will in the future which will negate anything and everything man has done. Main point though is trying to link what man is doing now to a historical catastrophic event is dishonest and as another poster said "hyperbolic BS" .

 

Never said anything about panic. Science shows us that CO2 in the atmosphere causes the earth to warm and burning over 700 million tons of coal a year along with millions of barrels of oil being burnt with the added effect of clearcutting millions of acres of forest and the loss of carbon into the atmosphere caused by tilling is bound to add up. Not to mention the obscene waste of building materials and resources. Hell...I could burn waste wood from one business and be warm all winter. The business sells tractors.

 

Actually it doesn't. Earth has had far more C02 in the atmosphere than today and been cooler than today.

Exactly! We all need to understand that the earth's average climate is overwhelmingly a product of solar activity. Atmospheric constituents have little impact and humans were not even around for most of the story.

 

That was not the actual article title. Why would you claim that?

This is a direct cut and paste from the Independent.

‘Great Dying’: Biggest ever mass extinction triggered by global warming leaving animals unable to breathe​

 

The link hidden in the middle does indeed say that...silly me I used the other link at the bottom where they usually are.

 

It was hidden. But whatever.

 

Maybe the Liberals can tell us: Why should we care about mass extinctions?

Isn't that just opening up the way for greater diversity of other animals to live in that habitat? The fact that we should care about one type of animal more than another sounds racist.

If one type of animal can't compete with another, I say we let them die.

 

So, what change in solar activity explains the current climate change?

 

Where do you start?

Because it is not just bout animals?

Because the ecology is a complex web that has inter reliances that can cause mass collapse, because I like eating regularly and if we have a mass extinction say bye bye to a guaranteed food supply?
