Climate Craziness of the Week – Mann's 'climate interpreter' claims 450 PPM CO2 will turn humans back into 'hunter-gatherers'

mann-psuHoly crap on a cracker! This Q&A with Michael Mann at some blog nobody has ever heard of called “Down with Tyranny” leaves me wondering, what is he smoking? I think the self imposed “climate interpreter” title needs some work.

-by Gaius Publius

One of my hats is as a climate interpreter to the interested lay person. I have something of a science background and can read the papers “in the original.” Another hat is as an occasional interviewer for Virtually Speaking. This month the two hats merged on the same head, and I got to interview the “Hockey Stick graph” climate scientist, Dr. Michael Mann. – See more at: http://downwithtyranny.blogspot.com/2014/10/michael-mann-on-climate-theres-very.html#sthash.y25kBteI.dpuf

[QUESTION] What level of CO2 is reasonable?

[ANSWER] Most still think that 350 ppm (parts per million) CO2 is what’s needed to keep us at the upper end of Holocene (era of civilized human culture) temperatures. For contrast, the ice ages averaged about 180 ppm CO2 at the bottom, and pre-industrial (pre-1750) concentrations were about 280 ppm CO2. Pre-industrial temperatures were at the bottom of the Holocene (post–ice age) temperature range, so there’s some headroom above that 280 ppm number. How much exactly? No one knows.

It looks like we’re headed for a IPCC-“safe” 450 ppm CO2 unless we stop. Not safe, IMO; nor in Dr. Mann’s. For starters, this “450 ppm” measures CO2 only, not other GHGs like methane and nitrous oxide. The effective ppm in “CO2 equivalent” with those other added GHGs is higher if only CO2 is at 450.

It’s roughly thought that the original ice sheet formations of 35 million years ago, which gave us modern Antarctic, Greenland and Arctic ice, occurred in a cooling environment that crossed below CO2 concentrations in the range of 550-400 ppm or so.

First, that’s a wide range. Second, that’s no indication of what will happen going the other direction, where the warming tipping points are. Hansen writes, correctly IMO, that real climate sensitivity depends on (a) the starting point (i.e., how near we are to tipping points), and (b) the direction (effect of warming of X amount is not necessarily correlated to the effect of cooling of that same amount).

Nevertheless, the massive uncertainty, plus the world-historical consequences, gives most of us pause. Me, I think 450 ppm CO2 is ultimately a death sentence for civilized humans. Back to life as hunter-gatherers for our third- or fourth-generation descendants. And if worldwide social chaos takes over before we stop, the process could run to conclusion, which, the old IPCC A1FI scenario says, tops out at +7°C warming.

On Mann:

“First, he’s actually good on the politics, better than most. But second, I wanted to get his thoughts regarding next steps. For me the key, core messages are — Stop Now… Zero Carbon “Budget” … Free Market Solutions Won’t Work. He surprised me in agreeing with the third point, and I hope he carries that message to the public going forward. He was already mainly on board on the first two, but I wanted to hear him say so for the record, since I hadn’t encountered his public comment on this. “

In recent decades the biosphere has been greening for some odd reason. World food production has recently been reported to be at record levels for some odd reason. Greenhouse growers typically recommend 1,000ppm for some odd reason. Finally, where is the worsening trend in extreme weather? It seems the more co2 we pump out the better things get!

Dr. Mann is actually right, just not quite the way in which he envisions it. When the earth reaches 450 ppm Co2 and the world sees that it has resulted in a boon for the bio-diversity of the planet, they will hunt and gather all the CAGW alarmists and demand their money back.

Randy, I’m guessing those are also the ones that have thought things through and know that without animal husbandry and agriculture, the earth would only support a small fraction of the current population. What could go wrong (they should be asking themselves)?
About month 2 or 3 or 4, when every bush and tree has been picked over and every bit of wild game has been taken, they will have to compete against the other hunter-gatherers for whatever is left. They better be prepared to eliminate the competition before the competition eliminates them.

Yes they do without external inputs a hunter gather society optimize it population on the land, the human population exceeds the lands carrying capacity human self correct the population adjust( that was a nice way of saying humans starve.) If the climate changes the human population will either expand or contract depending on the direction of the climate change, if the climate changes to much the wrong direction a hunter gatherer population will go extinct. I think the earth carrying capacity for hunter gather human population is less than a million, it could be large but I certain it would not exceed a hundred million. No we do not want to go back to those times, and I doubt 450 PPm of CO2 would cause that to happen most intelligent people would expect the opposite, of intelligent and Dr Mann are light years apart.

High Priests, medicine men, and shamans interpret “Signs from the Gods” for the common people (and if they value their heads, they slant the interpretation in favor of their rulers.) Since science is now incomprehensible to the common man (because our educational system has been subverted) media talking heads interpret it for us. Unfortunately for them, the “common man” isn’t as stupid as they’d like to believe.

It’s the form you put your climate code in that can be run through climate compiler down to the climate assembler and hence readable at one end by humans and the other by machines.

Permian had a 30 million year low of CO2 similar to our current 20 million year low. In between there was 250 million year period with 1000-2000 PPM and life flourished (with exception of those nasty asteroids).
450 is now bad? We should stay at 280-300 and wait for the next ice age to drop it below 150 and kill most land animals, including us? No I’m quite happy with increasing yields and CO2 climbing up to 600+ PPM.

Oh, you really do not want to know how often these people mention that feudalism is an appropriate model for the future. Herman Daly does it in his for the common good book. In the conclusion of my book I point to a deeply disturbing 2006 Club of Rome report published in Poland that metions feudalism as well. It’s not the moats or knight’s gear either. It’s the ability of political power to dictate what people can or cannot do.
The point I wanted to make though goes to the virtual reality modeling and gaming in the classroom and Next Generation Science Standards for K-12 in the US. They are all falsely teaching that the climate is a closed system. That what goes in must shift the ‘equilibrium’ somewhere. It’s not true, but students are to taught falsehoods so they will be primed to act from instinct and emotion and not facts.

Speaking of Plato, a good way to describe what is really going on in education as well as the Mann-led vision of CAGW is that we are all to think we are experiencing reality even though we are actually in a stage-managed cave looking at contrived shadows.
Mann yelps or sues when people try to call out that we are looking at mere shadows. We are supposed to accept the consensus that either is not acute enough to distinguish shadows from reality or has gotten lucrative financing to proclaim a certain truth without looking.
Here’s to continuing to perceive accurately instead of using the vision assigned.

I find it hard to believe that CACA advocates actually believe that falling CO2 caused Oligocene glaciation rather than the isolation of Antarctica by deep channels beneath the Southern Ocean, & that GHG levels falling farther caused NH glaciations in the Pleistocene, instead of the interruption of north equatorial currents by the closure of the Central American Seaway. CO2 levels are an effect of colder climate, not the main cause.

That will never happen or it’s game over. Off hand I can’t think of a counter-argument that they can use without abandoning their current position.

“….trees actually started to show a sharp decline in temperatures…..”
Tree rings don’t show temperature, what is your source for this? Tree ring may correlate with temperature if other factors are removed.
“1960 a period the alarmists are largely basing their AGW hypothesis on the trees actually started to show a sharp decline in temperatures.”
…but we know the temperatures were rising so this is nonsense. This is why tree rings dont “show temperature” as you put it.

Wow! I would have thought that the Malthusian theory was dead. Have these scientists ever heard of technology?

Malthus and carrying capacity has little or nothing to do with CAGW. We are burning fossil fuels. That means they will someday decline. That does not mean IPCC is right. And the soft limit shoe that pinches worst by 2050 is food calories. Liquid tranportation fuel is the other. Neither closely tied to CAGW.Study it out. Read my books, check the logic and footnotes, then counter. I may not be right. But bring substance, not religious opinion, to the debate. And heck, I am mostly on your side of the core argument!

rud: Have you never heard of methane hydrate? This will generate plenty of liquid carbon-based fuel, and it is virtually everywhere. It will provide plenty of liquid fuel.Natural gas is already being turned into diesel fuel, although the current low prices mean there is no rush to bring it to market. Given 40 years of development , methane hydrate will do the same.
As for the food calorie pinch by 2050 , this assumes an attempt to distribute all available calories equitably among the world’s population. Sadly, the population growth in many parts of the planet will be self limiting either through starvation, war, or famine. It is unlikely that the first world will be impacted significantly. It has ever been thus and likely always will be so. Unfortunately as we are seeing in Africa with Ebola, our best efforts and intentions cannot save everyone.

Hogwash. CO2 temperature sensitivity is far less than advertised. For every doubling of CO2 concentration we can expect a 0.2C temperature increase over ocean thanks to the strong regulatory effect of clouds. Over land we can expect an increase of 0.4 to 2C dependent on the propensities to generate clouds. CO2 also increases vegetation (feed the hungry) and stabilizes the environment. As I had said:
What then is this “Carbon Pollution”?

Its not the CO2 level that will turn us into hunters & gatherers, (what are left of us), but the economic chaos caused by attempted mitigation. Any even casual economist will agree that we are setting up to destroy our economies.
Did I read that the UK is expecting power outages this winter? With economic collapse caused by artificially induced energy price rises, we will experience food shortages next. And I am not talking about third world countries!

So I’m using wood, gas and electric to warm my house this fall. I’m worried about winter. We all got spoiled with all those mild winters (where I live). Our mild little September is officially over.

“I think 450 ppm CO2 is ultimately a death sentence for civilized humans. Dr. Mann says 405 ppm CO2 … ”
Duh … Hey, maybe they can be encouraged to off themselves if it gets to that level?
I have three items of CO2 monitoring equipment, an AZ7755 portable for quick on-site checks, a CO2 datalogger, and an older desktop meter, now rarely used. It has no data-logging but has a nice alarm to spook the uninformed. All are calibrated to 400 ppm. I tend to check that these are working properly at this time of year, because there are local triggers that make the task a bit more interesting. 450 ppm? Yep. got that last week for several daylight hours. Minor bushfire 2.3km upwind. Outdoor daylight readings around 400-410 early part of the day, increasing to 420+ late afternoon if airflow is off the Coral Sea. It always increases to 420+ after dark when photosynthesis shuts down. Indoors, we run the AC fairly light (to keep the bills down) so 1100 is the norm. Kitchen usually around 1400 unless the toast catches fire. Can’t see how 1000 ppm would be a problem. On the other hand, I might be unusual.

So, what da Mann is sayin’ is that an increase of approximately 0.08C of global warming is sufficient to completely destroy modern civilization and basically put us back into the Stone Age….
Yeah, right, Mann… sure it will…
Mann is barking mad… For 500+ million of years (Cambrian to Cretaceous), land and sea life THRIVED at CO2 levels ranging from 1000~7000ppm, and somehow the laws of physics, logic and reason suddenly cease to exist, because….. what, warmunists need more CAGW grant funding and governments lust for more power?

I hope you find these helpful. Again, I just want to put the basics in your brain — no reason to learn more than needed.”
All answers are mine. “mine” refers to Gaius Publius, although the text is a bit messy so I can’t tell for sure.

“Many were increasingly of the opinion that they’d all made a big mistake in coming down from the trees in the first place.”
Still in stiches over that one, and that was way before the idyllic hollowscene. The hollowscene really has little to recommend it except that is an INTERrglacial. Early Hominins probably descended from the trees just about 3.5 mya when it began to seriously chill out and CO2 may have been at roughly current levels.
It should be remembered that the initial Antarctic glaciation about 30mya was a temporary affair with CO2 levels very high and janky, maybe over 550 ppm.
This may actually be a new climate “forcing” that mikee has discovered and and if 450 (a mere 52 away/) forces a hunter gathering lifestyle, perhaps 550 will force us back up the trees?

As a new climate crisis skeptic myself, I eagerly read and enjoyed the book, although I thought the ‘bad guys’ were a little to hard to believe.

However, they do not want us to know that the planet only supported around 7 million humans 10,000 years ago. Oh dear, 99.9% of us will be surplus to requirements.

So he has to carry on with odd stories and warm-mongering of all sort. He hasn’t the guts to admit his manipulations. He is the living example of the old proverb „If you lie, stick to it, come hell or high water.“ Unfortunately, floods are getting fewer, but the alternative seems to be worth talking about.

The Left will turn humans into hunter gatherers just ask the Russians……..or the Chinese.

Lol, spoken with no sense of irony. It is precisely the mitigation policies if implemented to the full extent that would send humans back to hunter gatherers.

“For contrast, the ice ages averaged about 180 ppm CO2 at the bottom, and pre-industrial (pre-1750) concentrations were about 280 ppm CO2. Pre-industrial temperatures were at the bottom of the Holocene (post–ice age) temperature range, so there’s some headroom above that 280 ppm number. How much exactly? No one knows.”
Cherry pick, not? A skeptic might have written about CO2 levels being thousands of ppm in the past. So there’s some headroom above 45 0ppm. Quite a lot actually.

“…that’s no indication of what will happen going the other direction, where the warming tipping points are. Hansen writes, correctly IMO, that real climate sensitivity depends on (a) the starting point (i.e., how near we are to tipping points),…”

Let’s see if I get this right: In order to calculate the tipping point we need to figure out the ‘real climate sensitivity’ – which is best done when you are near to the tipping point – which you can calculate by…..

Hansen and his pals are rent seeking on every level: Circular arguments, redefinition of terms, control of data, fear mongering and of course a deep seated need for other people’s money. Did Sens. Wirth and Gore have any idea of the disservice they were doing by starting their bit of theater back in 1988?

Prof. Mann is a world class shark jumper already. Perhaps now he is working on a comedy career?

As someone who was educated and trained in the hard sciences, it’s just extremely difficult for me to believe that the difference between 3 parts in 10,000 and 5 parts in 10,000 can make that big of a difference in the amount of radiation absorbed and turned to heat. This isn’t like a chemical titration between an acid and base where there’s an immediate tipping point. An even if it were, there’s plenty of other factors that would serve as buffers.

Hunting and gathering mean he has to ditch his platform shoes. Hard to stalk in those.

Assuming CO2 is responsible for 100% of the warming (a really bad assumption, but let’s go with it for the moment), going from 280ppm to 400ppm has caused the earth to warm by about 0.7C. Now Mikey tells us that if we go another 50ppm to 450ppm, civilization is going to end?????

It’s called stop tyranny but says free market solutions aren’t the answer, tyranny is.
My irony meter just fell off the wall.

You know what “free market solutions won’t work” means?
It means: human freedom won’t work. “Free market” is used as a euphemism by statists for YOUR freedom to your own life.

The comprehensive failure of government the world over and its putative democracies will turn the trick long before climate change gets undressed.

200 PPM would make us hunter-gatherers, 100PPM …. and we all die.

“Mann’s ‘climate interpreter’ claims 450 PPM CO2 will turn humans back into ‘hunter-gatherers’
If anyone had doubt that the team wasn’t part of a world-wide group studying and reporting genuine science for human progressive interest and not political motivated pseudoscience environmental agenda, this was it.
CO2 changes in the planets atmosphere naturally are the effect caused by the climate mechanisms equilibrium movement. Cause and effect can not lead to being both the same equal positive feedback’s or the planet would have always been inhabitable. The cause would increase the effect and effect increase the cause in a viscous circle.(the planet has never shown this occur with CO2 always lagging behind temperature) The large increases in CO2 have had very little/ no noticeable influence on climate recently. The alarmists have been trying to trick the public that the previous atmospheric effect of changing climate is more concern than the cause. Just because one variable changes with another doesn’t mean both are proportional in either direction.
It colds outside so we put thicker/more layers of clothes on to keep us warm. Putting these extra layers of clothes on didn’t cause it get cold outside. Putting further layers of clothes on won’t continue it to cool outside either. So why should increasing the effect cause more warming, when the cause was responsible for it it the first place like the example just mentioned? Well it’s a greenhouse gas so some slight warming should be expected, but the biggest mistake is in thinking that changing the effect is bigger than changing the cause. The alarmist have tried to promote this pseudoscience, which has never been shown by the planet Earth.
Adding further 50 ppm CO2 will have a much smaller influence on global temperatures than the increase since the 1860’s. In a way I wish there could be a 150 ppm increase in just 5 years to show that it will make hardly any difference and end once for all this pseudoscience speculation.

True. Also, you wouldn’t survive.

This implies that it was warmer in the past than the current temperatures, therefore there is no unprecedented warming!! At least not yet.
