Unless we can agree to time scale and scope, even in some general way, it is very hard to discuss.
Can you lay out your time s ale and scope so we can compare ideas?

Do you see the ridiculousness of that thinking?

But isn't story telling the fundamental human trait? At least going back to cave paintings many thousand years ago, humans always tell stories, about past present and future. Predictions are just a human way of telling stories
Here’s the question: Could some version of extinction or near-extinction overcome humanity, thanks to climate change — and possibly incredibly fast? Similar things have happened in the past. Fifty-five million years ago, a five degree Celsius rise in average global temperatures seems to have occurred in just 13 years, according to a study published in the October 2013 issue of the Proceedings of the National Academy of Sciences.
Atmospheric and marine scientist Ira Leifer is particularly concerned about the changing rainfall patterns a recently leaked IPCC draft report suggested for our future: “When I look at what the models predicted for a 4C world, I see very little rain over vast swaths of populations. If Spain becomes like Algeria, where do all the Spaniards get the water to survive? We have parts of the world which have high populations which have high rainfall and crops that exist there, and when that rainfall and those crops go away and the country starts looking more like some of North Africa, what keeps the people alive?”
The IPCC report suggests that we can expect a generalized shifting of global rain patterns further north, robbing areas that now get plentiful rain of future water supplies. History shows us that when food supplies collapse, wars begin, while famine and disease spread. All of these things, scientists now fear, could happen on an unprecedented scale, especially given the interconnected nature of the global economy.
“Some scientists are indicating we should make plans to adapt to a 4C world,” Leifer comments. “While prudent, one wonders what portion of the living population now could adapt to such a world, and my view is that it’s just a few thousand people [seeking refuge] in the Arctic or Antarctica.”
“All the evidence points to a locked-in 3.5 to 5 degree C global temperature rise above the 1850 ‘norm’ by mid-century, possibly much sooner. This guarantees a positive feedback, already underway, leading to 4.5 to 6 or more degrees above ‘norm’ and that is a level lethal to life. This is partly due to the fact that humans have to eat and plants can’t adapt fast enough to make that possible for the seven to nine billion of us — so we’ll die.”
There are some possibilities that are deliberately left out of the IPCC projections, because we simply don’t have enough data yet to model them. Jason Box, a visiting scholar at the Byrd Polar Research Center told me in an email interview that: “The scary elephant in the closet is terrestrial and oceanic methane release triggered by warming.” The IPCC projections don’t include the possibility — some scientists say likelihood — that huge quantities of methane will be released from thawing permafrost and undersea methane hydrate reserves. Box said that the threshhold “when humans lose control of potential management of the problem, may be sooner than expected.”
The head of the IPCC, Rajendra Pachauri, speaks for the scientific consensus when he says that time is fast running out to avoid the catastrophic collapse of the natural systems on which human life depends. What he recently told a group of climate scientist could be the most chilling headline of all for the U.N. report:
"We have five minutes before midnight."
It seems to be widely assumed that humans can adapt to any amount of warming, on the basis that humans live in such a wide variety of climates now. We show that when examined in terms of the peak value of the wet-bulb temperature (Tw), which ultimately governs the possibility of transfer of metabolic heat to the environment, the worlds present-day climates are far less variable than one might think based on mean temperature. A warming of only a few degrees will cause large parts of the globe to experience peak Tw values that never occur today; 7C would begin to create zones of uninhabitability due to unsurvivable peak heat stresses (periods when the shedding of metabolic heat is thermodynamically impossible); and 10C would expand such zones far enough to encompass a majority of today's population. It is unknown how much of our present 7- 10C cushion we can live without before experiencing significant problems, making it difficult to draw conclusions about more modest climate changes, but the limits themselves rest squarely on basic thermodynamics.
If everyone really looked hard and unblinkingly at the true, raw facts of what horrors our lifestyle is creating and will produce, that would on the one hand be a step toward a kind unflinching honesty sorely lacking in our culture, and on the other hand would likely be sufficient in some cases to prompt deep changes in many peoples lifestyles and perhaps prompt other effective actions (and non-actions).
A small, very spoiled child might go through her day smashing things and always refusing to even look at the damages and harms she has caused to people and things. I think we ought to hold ourselves to ever so slightly moral standards than such utterly spoiled children and at least look at the damage we've inflicted on the world and its inhabitants.

I would compare predictions with real data. For example,

Given this, I think a "fixed position" would involve assuming that economic output will keep rising indefinitely. But that can only happen if resource availability is significantly reversed.

Correct. Which is the opposite. Polarities are like love affairs. Because we have this denial still resilient in those who take this fixed position that economic growth will rise indefinitely, we can find plenty just the polar opposite who see themselves as truth warriors by taking the fixed position that we are going extinct. This is a dance of sorts.
