Nemesis @ 434, Your link asks, "What if BECCS isn’t up to the task?" and shows pretty conclusively BECCS isn't up to the task. And of course we also know CCS certainly isn't up to the task, and probably never will be. Most people think it is impossible from the physics POV. At best an expensive and minor help. Certainly not scaleable. But I would ask you why people are even still working on CCS and BECCS when BCCS is already proven to work and already scaleable? "If all farmland was a net sink rather than a net source for CO2, atmospheric CO2 levels would fall at the same time as farm productivity and watershed function improved. This would solve the vast majority of our food production, environmental and human health ‘problems’." Dr. Christine Jones That's based on Dr Jones work and multiple 10 year case studies to back it up done on real world working farms and ranches at scale. There is no cost to it either. ALL the farmers in the case studies made MORE profits not less as soil carbon rose approx 5-20 T CO2/ha/yr. My guess is that CCS and BECCS are simply funded by the merchants of doubt as a way to misdirect and obfuscate people away from what is already well known, namely: “Yes, agriculture done improperly can definitely be a problem, but agriculture done in a proper way is an important solution to environmental issues including climate change, water issues, and biodiversity.”-Rattan Lal

nigelj:
There’s a good book on this “The Moral Arc” by Michael Shermer...The book “Behave” by Robert Sapolski touches on the issues as well.
Yeah, I linked to Steven Pinker's The Better Angels of Our Nature, but you'd need to click on the link to know that ;^).
Looking just at the economics and wealth distribution, this is far more complicated. Hunter gatherers were moderately egalitarian, then farming widened the income and social gaps as society became larger and more specialised, and became a natural feature persisting for a lengthy time and peaking in the industrial revolution.
It's complicated enough, and verifiable data scanty enough, that the range of humanity's probable futures includes both extinction, and continued population growth accompanied by extinction of all other species but domesticates and synanthropes.
Bit of a roller coaster.
That's a vivid metaphor, and apt to an extent. One global ecological trend that's been relentlessly positive for at least 10,000 years, however, is human population growth.

Mal Adapted 413, You wouldn’t be trying to say, perhaps, “people are monkeys”??
Oh my, no. Primates yes, monkeys no - the Hominidae apparently separated from other catarrhines in the early Miocene. Homo sapiens sapiens is the last surviving species of the hominid genus Homo. By genome match, our nearest extant relatives are in the genus Pan, chimpanzees and bonobos. Like every species, however, H. s. sapiens has unique adaptations.

Has anyone had a chance to read and comment on the very recent article "The application of machine learning for evaluating anthropogenic versus natural climate change" by John Abbot and Jennifer Marohasy in GeoResJ at http://www.sciencedirect.com/science/article/pii/S2214242817300426#! Seems they concluded the Equilibrium Climate Sensitivity (ECS) to be approximately 0.6 °C.

BPL I do hope your work in astronomy is much better than your gullibility over Assange et al. (sheesh) logical fallacies might be compelling for the gullible believer but they don;t = facts evidence nor the truth. seriously, take a chill pill. You're swimming in an ocean of biased disinformation and apparently don;t even realise it. This is bordering on 9/11 truther/birther/alien abduction bs. Seriously, it is.

Kevin ... "I don’t want to have to interpret your posts…" while assuming I must be the only cause of the problem? Aha. You seemed to work out I mentioned steve keen ok .... and why. Not only don't I try too hard, frankly I do not 'try' at all. :-))) https://www.youtube.com/watch?v=BQ4yd2W50No

428 Kevin McKinney, umm, ok. "it" = "the vexed topic of transition to a sustainable world" as per: "I have already stated my position on that topic on a number of occasions. Basically it isn’t going to happen voluntarily nor by planned intent. iow not going to happen "voluntarily" nor via a "plan"

418: "While most here would not hold a belief in Karma maybe some do get the truism of “What goes around, comes around” …. eventually? ;-)" Unfortunately this is a logical fallacy, invented to make people believe we live in a just world where good things happen to good people and vice versa. The reality is completely different, sometimes decent people get the hand of God down on them and evil people go unpunished for their crimes. In my experience it seems to be one of the favourite fallacies of those of right wing political leaning. https://youarenotsosmart.com/2010/06/07/the-just-world-fallacy/

Kevin McKinney, dear fellow, why ask a grasshopper how to learn to live like an ant? Anywho... Hopefully you read the article on EROI posted prior to this. Nothing new to you, I hope, but a confirmation of the fall of the House of Growth, including the silly decouplibg discussed here, as well as other silly things. Sadly, they did not address ERO*E*I. Ah, well. Gift horses. I haven't been dwelling on energy for a long while so EROI and EROEI slipped my mind amidst all the techgrowthiness going on here. It's an excellent short answer for the issue. I've fallen into the habit of just noting resource limits because, well, it's the same darned thing. I'll just leave this here as shorthand for my statement on why what is cannot continue to be and trust you can recall all the more detailed and nuanced points I might make. Well, then, what to do? Said issues of resources will bring down capitalism and big gov even if we do nothing to facilitate their fall, but it is hardly ideal to put on a blindfold and jump into unknown space. Managed descent is required. The problem is the solution: Falling EROEI/E percapita? Don't need energy, or need far less. Simplify. Don't trust Inc's or gov? Local energy. Distributed energy. Which resilience aka regenerative systems require, anyway. Don't trust Big Ag? Little ag aka distributed ag aka regenerative ag aka localized ag. Which is what we should do, anyway as in the previous graph. Etc. Simplify. How, exactly? If top down ain't working, try bottom up. Do the above things by starting small. Start with food and water. Grow, capture, store. Make a council for your little slice of heaven. Learn to do egalitarian. Learn to do Commons. Teach others as reality imposes itself on their little brains. Learn permaculture and/or other restorative approaches. Learn to define sustainability correctly: Endlessly repeatable barring acts of god or universe. Accept nothing less in principle and only the solution for each problem that gets meaningfully closest to this in practice. Remember: Sometimes the solution is to just not solve the problem and merely let go. Do same for city/region, bio-regon. If you have food, water, shelter, all else can be sorted out amongst yourselves. Let EROI/EROEI/RESOURCE DEPLETION/CLIMATE do their dirtiest and just watch the Titanic sink from your comfy little lifeboat. Out of time. *Maybe* more later.
