Rate of change in the Ordovician extinction

[elektra]

LOL Damn, with every post, you demonstrate that you are a fool. An abstract is a summation of the paper. The main body outlines the methodology and evidence. Obviously you have never bothered to read peer reviewed scientific papers.

An abstract could summarize the paper or it may not. Unless you can present the paper you have no way of knowing.

Carry on old crock. I got to punch out.

I am at SpaceX inspecting rockets

 

[Old Rocks]

No, I do not. But the scientists that wrote the paper do.

Cool story.
What was the fastest rate per decade in the P-T extinction?
How about the fastest rate per century in the P-T extinction?
The fastest rate per millennium in the P-T extinction?

According to the scientists who wrote that paper, of course.

Well now;

Abstract​

The Late Ordovician mass extinction (LOME) included two phases (I and II) of high species turnover that have been hypothetically linked to the Hirnantian glaciation and subsequent rapid warming, respectively. However, the timing and tempo of the LOME remain uncertain, which hinders our understanding of the feedback between the LOME and paleoclimatic change. Here, we present high-precision radioisotopic dates for the Ordovician-Silurian transition in South China that reveal the LOME began at 442.76 + 0.35/−0.22 million years ago, with the two phases lasting for 0.34 + 0.46/−0.34 and 0.06 + 0.31/−0.06 million years, respectively. The rapid switch from icehouse to greenhouse conditions, along with the higher mean rate of temperature change during LOME II, resulted in a much higher mean extinction rate during LOME II than I (71.6% versus 8.4% species loss per 100 thousand years, respectively), implying that the rate of climate change was a primary control on the tempo of the LOME.

That paper is open, so you can read the whole paper. Really, you can read the whole paper. Maybe you would actually dare do that?

 

[westwall]

Now Westie, you have repeatedly proven yourself a fool. Dr. James Hansen is one of the most respected atmospheric physicists in the world. And you are what? A science denier, a posier who apparently cannot read real scientists papers.

He was off by over 100% you retard.

Try again.

I don't see any proper comparison to your claimed one decade of warming.

Well perhaps someday you may learn to read a scientific paper with a degree of understanding.

So, per usual you have nothing.

Very disappointing. I was hoping after your long absence (jail?) you would have actually learned something.

Hansen, J., D. Johnson, A. Lacis, S. Lebedeff, P. Lee, D. Rind, and G. Russell, 1981: Climate impact of increasing atmospheric carbon dioxide. Science, 213, 957-966, doi:10.1126/science.213.4511.957.

The global temperature rose 0.2°C between the middle 1960s and 1980, yielding a warming of 0.4°C in the past century. This temperature increase is consistent with the calculated effect due to measured increases of atmospheric carbon dioxide. Variations of volcanic aerosols and possibly solar luminosity appear to be primary causes of observed fluctuations about the mean trend of increasing temperature. It is shown that the anthropogenic carbon dioxide warming should emerge from the noise level of natural climate variability by the end of the century, and there is a high probability of warming in the 1980s. Potential effects on climate in the 21st century include the creation of drought-prone regions in North America and central Asia as part of a shifting of climatic zones, erosion of the West Antarctic ice sheet with a consequent worldwide rise in sea level, and opening of the fabled Northwest Passage.

The Northwest Passage first opened in 2007. In 2016, a 1000 passenger luxury cruise ship transited the Passage. We have seen increased droughts in drought prone area, as well as increased melting in West Antarctica. But you say this is not happening? My, what a liar you continue to be. Who pays you for that kind of shit? After all, every Scientific Society in the world that is involved in geology says you are full of shit.

"Potential", "could", "suggests". Notice how these frauds never use anything but weasel words?

J. Tuzo Wilson said "you will find transverse faults, this is how you will find them, and this is what they will look like."

Notice the difference?

The northwest passage was open in the late 1700's too. They just didn't have a reason to traverse it.

A sailing boat was able to sail 300 miles further south, towards the South Pole in the 1850's than you can today.

How come?

And I am on Mars, inspecting Musk's Mars Station. LOL

I know it pisses you off. I am here working on rockets for Elon Musk. I can actually say I have worked on the industrial chemical plant used to make solar panels and wind mills. I have worked on geothermal fossil and nuclear plants. Nuclear submarines.

It does not take much to call you out, all you do is copy and paste with zero understanding of what you posted. Then you argue as if you understand what you posted.

Here you make claims about studies but you dont post or even read the study. You have a belief nothing more

 

[ding]

LOL Sure nothing special, except it is going right off the chart. And the normal variations are not going to make it go down. And the increased heat will create a rapidly changing and very energetic climate. Such as we are seeing right now.

It isn't. It's no different than any other climate fluctuation which the geologic record is full of.

That's amazing considering how ignorant you are of the planet's climate record. It's pretty crazy that you didn't know the planet transitioned from a greenhouse state to an ice house state over the last 50 million years or that CO2 lagged temperature by 1000 years.

 

[ReinyDays]

Warming rate for the period in the opening post was 12.2 C per 100,000 years. That would be 1.22 c for 10,000 years. 0.122 for 1000 years. 0.0122 for 100 years. Simple math. But you could not do it?

How are you measuring tenths of degrees from 400 million years ago? ... I didn't think uranium's alpha emissions were proportional to temperature ... care to explain ... a link is fine ...

 

[Toddsterpatriot]

Well perhaps someday you may learn to read a scientific paper with a degree of understanding.

If you have any paper that shows the rate of warming per decade
during the Late Ordovician mass extinction (LOME), you should definitely
post it here to highlight my misunderstanding.

 

[Sunsettommy]

I see that Old Rockhead is continuing his lies about this which I destroyed recently which he ignored even though they are well known and recorded.

The Northwest Passage first opened in 2007. In 2016, a 1000 passenger luxury cruise ship transited the Passage. We have seen increased droughts in drought prone area, as well as increased melting in West Antarctica. But you say this is not happening? My, what a liar you continue to be.

I destroyed his lies at Post #63 LINK and at POST #80 LINK

Everything I challenge old crock ding-a-ling you come to his defense. Ding-a-ling must be old crock or in love.

I challenged old crock to post a study, ding-a-ling butts in and posts colored pics.

Sorry ding-a-ling. A colored line that is 2 or 3 inches long is not a study.

You aren't helping opposition to AGW by denying data from the geologic record, dummy.

What is even more amazing is your pictures do not prove what you think.

Post the study the pics came from ding-a-ling so we can have a real discussion.
