So on the one hand a group of posters (let's drop the nomenclature for now) who are constantly citing scientific studies, while on the other hand you have a group of posters that just state their biases, and make unsupported accusations to the other group of (ironically) confirmation bias, when they are not simply making unsupported 'arguments from incredulity.' http://rationalwiki.org/wiki/Argument_from_incredulity
I'm pretty sure that, in other contexts, since you are a pretty sharp fellow, you would say that it was the first group of posters who had the edge on the latter group (unless the latter group can come up with a broad set of studies that either disprove the those of the first group, or that come up with alternative findings).
I have, in fact, posted articles that go against a 'doomer' perspective, if you will. When there was good evidence that the Greenland Ice Sheet might be melting a little LESS quickly than thought, I posted that, iirc. I actually would love to find hundreds of articles that say everything is going to be fine, or that feedbacks are never likely to kick in, or that previous studies were too dire and it looks like things are much less bad than predicted.
But pretty much all I can find say the opposite.
If you can find a bunch of legitimate articles that that show that the icecaps aren't melting or that global temperatures aren't increasing or that past extinctions (which showed CO2 increases much slower than today's) didn't wipe out most life on the planet....
IF you can find a number of legit articles from legit sources like this, please, please post them.
I for one will be ecstatically delighted.
But if you can't, then you can't accuse us of selection bias or confirmations bias, you should apologize to us for falsely accusing us of the same, and you should...cease and desist.
Have a nice day!
(It should be pointed out that, in my case at least, I hardly represent the doomiest voice available, even among academics/scientists. Guy McPherson famously has said that total human extinction is inevitable within, what is it now, 16 years? I certainly don't make anything close to that claim.)

Much of our information on past climates comes from the composition of sediments and the shells of marine organisms, which take up chemical substances from seawater as they grow. Because seawater chemistry is partly controlled by temperature, sediments and fossil shells retain a signature of the ambient temperatures under which they formed. Such signatures tell us that during the PETM, temperatures rose rapidly over approximately 6,000 years, and then gradually cooled to near-background levels over the next 150,000–200,000 years. Warming was not uniform across the globe: sea surface temperatures increased by ~6 °C at high latitudes and ~4 °C at low latitudes, and deep-water temperatures increased by ~8 °C at high latitudes and ~6 °C at low latitudes. On land, temperatures increased by ~5 °C in the middle latitudes and by ~3 °C near the equator. Evidence for changes in precipitation is mixed: some studies show a dryer climate during the peak warmth of the PETM, whereas others suggest that rainfall increased. This may demonstrate that the impact of warming on precipitation patterns was localized, with different regions showing a range of effects.
Mammals underwent profound evolutionary and biogeographic changes at the Paleocene–Eocene boundary. Three groups that incorporate many modern mammal species appeared suddenly at this time: Artiodactyla, which includes deer, camels and cows; Perissodactyla, which includes horses and rhinoceroses; and Primates, which includes monkeys, gorillas and humans. These groups probably originated in Asia and then rapidly dispersed to Europe and North America, all within the space of a few thousand years. It seems likely that movement between continents occurred over high-latitude land bridges (such as Greenland or the currently submerged land bridge under the Bering Strait), which only became warm enough to access during the PETM. A number of more ancient Paleocene mammals also went extinct at this time.
The best-known record of mammalian evolution throughout this interval, and indeed for much of the Cenozoic, comes from the Western Interior of North America. In the Bighorn and Clarks Fork basins of Wyoming (Fig. 3), sediments that were deposited on ancient flood plains record in great detail environmental change across the PETM. Mammal fossils recovered from this interval not only show the rapid first appearances of the artiodactyls, perissodactyls and primates in this region, but also demonstrate that some types of mammal became smaller during the PETM. Fossils of the now-extinct ground-dwelling herbivores Ectocion and Copecion from the PETM interval are reconstructed as approximately half the weight of those before and after it, and several other mammal groups that survived the PETM show the same pattern. The earliest members of the artiodactyls, perissodactyls and primates were also much smaller than their immediate descendants. Elevated atmospheric carbon dioxide concentrations have been shown in laboratory experiments to reduce leaf digestibility and nutritional value for herbivores, which results in slower growth rates. The higher concentration of atmospheric greenhouse gases during the PETM therefore seems like a better explanation for mammalian dwarfing than the increase in temperature itself.

This paragraph I wrote needs repeating. We see the damage we have wrought and so dreadfully misinterpret our vulnerability. Our planet is not in peril. We are.
When any species is in overshoot and approaches collapse it becomes the most vulnerable component in the eco system, this is not true for just humans. It is an ecological reality. As an example. When moose or deer or lemmings experience a popualtion explosion and go into overshoot they severely deplete their preferred forage and then mill through lesser forage virtually stripping the under story of forests. At the peak of overshoot one looks at the forest under story and sees all the damage the moose have done and all the plant species under stress. It looks like these plant species are the ones endangered not the thousands of moose in overshoot. This is where we are now with human overshoot. We are focussing on all the natural ecosystems that we have put under stress and see them all as vulnerable. It can't possibly be the 8 billion humans, so abundant, are vulnerable after all the damage and hubris we have caused. But we get this narrative all wrong. The minute consequences start correcting human overshoot, from that moment native ecosystems start to heal. The minute the moose population collapses the forest starts to regenerate. Within 10 years the forest under story is once again lush. As a first step in explaining this new orientation you have to recognize that a species in overshoot standing before a collapse is the most vulnerable component in the ecosystem. Always has been. Always will be.

Why we have such a complex dynamic being reduced to sweeping visions of doom? The sub culture of doom warriors here browse the internet and copy and paste links and claim to be learned and objective. They sit down every day and search exactly those topics and studies that reinforce their already fixed opinions, in fact they start to specifically search only the most extreme positions because their fixed positions of our civilization spiraling down the toilet has to seek out ever more dramatic forecasts and predictions.
These folks are like clams. They are isolated in their cyber shells, they are filter feeders, they filter out the most extreme positions and eject these sweeping visions of doom out of their anal sphincters and spew these excretions all over this site in the form of link after link of guaranteed, bonified and certain doom and extinction coming our way.
A peak behind the cyber wall reveals their true identity

Except that for many decades "minute consequences" did not "[correct] human overshoot."

Also, I think the default view is not doom but the opposite, which in turn requires acting like clams.

Sooo, you are equating imagined "...possibilities and explored pathways..." as evidence.
Apparently we have such different ideas of what constitutes such a basic word as 'evidence' that I'm not really sure that further useful communication is possible? What other very basic words do you have your own 'unorthodox' definitions of? Perhaps you've been living out in the woods a bit too long??
Do I need to present evidence about a yet unknown outcome?

I don't need to actually plot this out in a graph. I can feel it, intuitively. Every time I pick up more doomy news (which I do without even having to go looking for it), those adjectives keep showing up. So if this keeps up, then we're already in the dreaded AGW feedback loop and for some stupid reason scientists won't start leading the gunsight ahead of the target, so to speak. But I am. I'm not sure I can bring myself to believe ultra-short-term doom ala Cid, but I have a palpable sense of acceleration.
I don't have nearly the same sense of urgency with fossil fuel depletion, which is why I am not really in sync with the remaining hardcore peak-oil doomers.

I have from the beginning spoken of possibilities and explored pathways.
But measuring the use of words like "Ever more "faster than" and "warmer than" and "dryer than" expected."is not a valid way to determine the truth. You may be just consuming a media buzz where a theme is deliberately pushed forward and they are using repetition to convince you.

Not if it is used by the scientists themselves especially in the research they do.
You try to conflate far to much in that scrambled statement.
Yes if reporters are using the terms, and NOT reporting the scientists use of the terms you have a claim.
However when the scientists are using the terms, even if the reporting of the scientific usage of the terms is by the media, your point then is simply, a talking point of denial.
Even scientist are often guilty of using hype to promote their work as it leads to funding.

Not in the research papers they write that have already been funded.
Still pushing that talking point instead of trying to deal with the ACTUAL SCIENCE.
