Another Alarmists Sacred Cow Bites the Dust

[SSDD]

Consensus is a synonym for majority opinion. The consensus in science has certainly been more often correct than anything you've been working with.

Sorry guy...guess you are as ignorant of history as you are of everything else...in matters of science, especially relatively new areas of science, the consensus has been wrong almost 100 percent of the time. Perhaps when the glassy eyed cultists are swept from the playing field, and 20 or so years pass in an effort to undo the damage that they have done to science and some actual research gets done...repeatable research in which the data and methods aren't hidden from the public...then perhaps the view will at least offer up a closer match to reality...and blatant data manipulation won't be necessary to give the appearance of something that isn't there.

REALLY?!?!? That would mean there have been NO scientific advances over whatever time period you're actually pretending to talk about. Care to explain?

Really? Where the fuck did you get that one?

The Permian–Triassic (P–Tr) extinction event, colloquially known as the Great Dying,[2] the End Permian or the Great Permian Extinction,[3][4] occurred about 252 Ma (million years) ago,[5] forming the boundary between the Permian and Triassic geologic periods, as well as the Paleozoic and Mesozoic eras. It is the Earth's most severe known extinction event, with up to 96% of all marine species[6][7] and 70% of terrestrial vertebrate species becoming extinct.[8] It is the only known mass extinction of insects.[9][10] Some 57% of all families and 83% of all genera became extinct. Because so much biodiversity was lost, the recovery of life on Earth took significantly longer than after any other extinction event,[6] possibly up to 10 million years,[11] although studies in Bear Lake County near the Idaho city of Paris showed a quick and dynamic rebound in a marine ecosystem, illustrating the remarkable resiliency of life.[12]

There is evidence for one to three distinct pulses, or phases, of extinction.[8][13][14][15] Suggested mechanisms for the latter include one or more large meteor impact events, massive volcanism such as that of the Siberian Traps, and the ensuing coal or gas fires and explosions,[16] and a runaway greenhouse effect triggered by sudden release of methane from the sea floor due to methane clathrate dissociation or methane-producing microbes known as methanogens;[17] possible contributing gradual changes include sea-level change, increasing anoxia, increasing aridity, and a shift in ocean circulation driven by climate change.

Where I see NOTHING in the way of a fucking ice age you fool.

Crick, there is some evidence of a brief, tens of thousands of years, very cold period during the worst of the Siberian Trapps eruption. So, yes, there could have been a die off from that. But that cold period would not have resulted in the massive marine die off. And the isotopic proxies all say that there was a very hot and long period when the GHGs put up by the Trapps and the coal seams the Trapps came into contact with, created enough heat to trigger a massive release of CH4 from clathrates.

For as long as I have been here, the PT extinction has been periodically held up as an example of a run away greenhouse effect killing off most of the life on the planet. Thinking people know this isn't true as the atmospheric CO2 levels had previously been much higher than they were during the period of transition between the Permian and the Triassic periods without any such run away greenhouse effect, but then aren't thinkers...they are alarmists...

Here are some examples of statements made on this board regarding the PT extinction event...and there have been many...

Now there are a many more papers confirming the very rapid rise during the PT Extinction Event. Very easy to find, just use Google Scholar, and put in "Evidence for the increase of GHGs during the PT Extinction Event". What a shame that an old millwright has to teach this to a supposedly educated man.

There are a number of times in the geological history of the earth that a waming became selfsustaining, the PT extinction was just one of them.

The record of the Milankovic Cycles show that. The longer geological record shows that rapidly adding GHGs to the atmosphere creates a very rapid warming, and that very rapid warming creates extinction events. PT event, as well as others.

Lordy, lordy, faux geologist, you are one dumb fuck. PT Extinction.

Anyway, somehow in today's bitterly partisan scientific environment, some actual science slipped past the gatekeepers, and it seems that that PT extinction wasn't due to a run away greenhouse effect, and very high temperatures at all....it was due to an ice age. All thinking people know that cold is the real killer.. Life on earth has always flourished during periods of warmth exceeding the present by a wide margin...cold, on the other hand makes life very hard...but then again, alarmists aren't thinkers...they are political hacks who will say whatever they think is necessary to scare people who don't agree with them whether it makes sense or not.

Cold extermination: One of greatest mass extinctions was due to an ice age and not to Earth's warming

The Earth has known several mass extinctions over the course of its history. One of the most important happened at the Permian-Triassic boundary 250 million years ago. Over 95% of marine species disappeared and, up until now, scientists have linked this extinction to a significant rise in Earth temperatures. But researchers have now discovered that this extinction took place during a short ice age which preceded the global climate warming. It's the first time that the various stages of a mass extinction have been accurately understood and that scientists have been able to assess the major role played by volcanic explosions in these climate processes.


Ice age, not warming, explains Permian-Triassic extinction event

Ice age, not warming, explains Permian-Triassic extinction event
The ice age lasted just 80,000 years, but the extreme cold was enough to kill off the majority of marine species.

Precise U–Pb age constraints for end-Triassic mass extinction, its correlation to volcanism and Hettangian post-extinction recovery

There is actual physical evidence for a global ice age. There has never been one iota of physical evidence to support the idea that run away heat caused it. The only place that it ever existed was in the fevered imaginations of global warming fanatics.

Once again, you are a liar, or you don't know much about geology.

Nickel, life and the end-Permian extinction

Some modern members of the prokaryote Archaea that decompose organic matter to produce methane have a metabolism that depends on Ni, one genus being Methanosarcina that converts acetate to methane by a process known as acetoclastic methanogenesis. Methanosarcina acquired this highly efficient metabolic pathway probably though a sideways gene transfer from Bacteria of the class Clostridia; a process now acknowledged as playing a major role in the evolution of many aspects of prokaryote biology, including resistance to drugs among pathogens. Molecular-clock studies of the Methanosarcina genome are consistent with this Archaea appearing at about the time of the Late Permian. A burst of nickel ‘fertilisation’ of the oceans may have resulted in huge production of atmospheric methane. Being a greenhouse gas much more powerful than CO2, methane in such volumes would very rapidly have led to global warming. Before the Siberian Traps began to be erupted nickel would only have been sufficiently abundant to support this kind of methanogen around ocean-floor hydrothermal springs. Spread globally by eruption plumes, nickel throughout the oceans would have allowed Methanosarcina or its like to thrive everywhere with disastrous consequences. Other geochemical processes, such as the oxidation of methane in seawater, would have spread the influence of the biosphere-lithosphere ‘conspiracy’. Methane oxidation would have removed oxygen from the oceans to create anoxia that, in turn, would have encouraged other microorganisms that reduce sulfate ions to sulfide and thereby produce toxic hydrogen sulfide. That gas once in the atmosphere would have parlayed an oceanic ‘kill mechanism’’ into one fatal for land animals.

A very interesting article. And, like virtually every article I have read that has been published in the last two decades, the primary cause of the PT extinction was the very warm period created by the GHGs released that cause the clathrates to release the methane into the atmosphere. "Extinctions", by Norman MacLeod is a very good source on this subject.

You folks have been claiming that there was sort of a silent majority of climate scientists who knew that the world wasn't really getting warmer and that there's no such thing as the greenhouse effect and that most climate scientists are criminal frauds who've been lying en masse for many years now and have manufactured this whole mess.

You've told us that when Trump got elected, all that would come to a stop. The money funding climate research that demanded findings support AGW would dry up overnight and the real science would finally come to the fore.

Well, I know Trump has only been in power for, what, 51 days. But can you show us any signs that what you said would happen is starting to happen? Are the real scientists starting to speak up yet? Are any of these enormous hoaxes starting to crumble? Well? Anything?

 

[polarbear]

What's to be spoken out ?
The Google trend shows that nobody cares any more about climate change. There was a little spike after Scott Pruitt was confirmed and shortly after zilch, world-wide.

To my surprise the same trend in Germany,
Trump's budget made it quite clear, no more money will be wasted on climate change.
So who should pay for these scientists to come forward and speak out knowing nobody cares any more.?

 

[polarbear]

You can see the same disproportionate numbers in the youtube views.
The omygod climate change videos have waaaay less views than videos like these:

 

[Crick]

Are you actually suggesting that You Tube views and Google searches accurately represents the opinions of climate scientists?
