”If you are in the slightest doubt about what the climate change alarmists are trying to get us to do –and pay for — you should read this book.” –Dr. Peter Walsh, Geologist, London, England

”This book clearly shows that carbon dioxide is our friend. We should be producing more of it.” –Aert Driessen, Geologist, Canberra, Australia

”The real science of global warming and climate change, which is explained in this book, will leave you scratching your head and asking what all the fuss is about why we have to tax a gas that we breathe out and also use to make fizzy drinks, and how we got ourselves into this contentious political position… and that is also explained.

If you are beginning to have misgivings about the extreme language and alarmist predictions on global warming and extreme weather events coming from the IPCC and kindred environmental groups, then this book is for you. It is easy to read (the lead author is not a scientist) but, that said, he has chosen two eminent scientists of international standing as co-authors. The strength of this book lies with the way that it explains the science; indeed the lead author has been described elsewhere as ”the great explainer” on the basis of previous books, mainly on economics and marketing.

Descriptions of follies in bygone years stemming from hasty and wrong interpretations of scientific data, and sometimes even data manipulation, feel familiar and form an intriguing backdrop to the global warming folly. I refer, inter alia, to the banning of DDT to control malaria (1972) on the basis (without evidence) that it killed birds and was linked to cancer (both untrue). In 2006 the World Health Organization (WHO) came to its senses and supported a partial reintroduction of DDT (for spraying indoors but not before the preventable deaths of 50 million people, mostly children. Other follies cited include a purported link between measles vaccinations and autism (1998, untrue, and it led to a terrible measles outbreak in Wales in 2011), Professor Paul Ehrlich’s prediction that the world would experience mass starvation in the 1970s and ’80s (that never happened but did lead to China s one-child policy), and the Club of Rome’s predictions that the world would run out of mineral resources (still waiting). All these follies, including the folly of ‘stopping climate change’ get their traction and momentum from sensationalized reporting by mainstream media and opportunistic politicians that see votes in large sections of an unquestioning populace.

The book also explains how, as an inhabitant of the Solar System, Earth’s climate is influenced mainly by our Sun, and that should come as no surprise. Indeed the book clearly shows that carbon dioxide is our friend and we should be producing more of it.” Aert Driessen, Geologist, Canberra, Australia –Reviews

The strength of this book lies in the way that it explains in simple ways the complex science of many disciplines — atmospheric physics, astronomy, meteorology, geology, and more. It is well illustrated and referenced. And what this science shows, backed by much compelling evidence, some irrefutable, is that carbon dioxide has very little to do with climate change, in either direction (hotter or colder). The book also explains how, as an inhabitant of the Solar System, Earth’s climate is influenced mainly by our Sun, and that should come as no surprise. Indeed the book clearly shows that carbon dioxide is our friend and we should be producing more of it.” –Aert Driessen, Geologist, Canberra, Australia

”This book should be compulsory reading for everyone seriously interested in the Earth s future global warming alarmists included.” –Wyss Yim, Professor of Earth Sciences, Hong Kong

”…Should be issued for use by every teacher of any science classes from Grade 7 to the first years of college.’ ‘–Gary Sharp, Professor, Center for Climate/Ocean Resources, California –Reviews

About the Author

About Face! is the product of two scientists and an economist. The scientists are Madhav Khandekar in Canada and Cliff Ollier in Australia, plus economist Arthur Middleton Hughes in the USA. Carbon Dioxide (CO2) is essential to all life on earth. It is plant food. We believe that the more CO2 there is in the atmosphere the bigger and better plants will grow all over the world. Three million people die each year because the prices of food are too high for them. We want to increase CO2 in the atmosphere and reduce world malnutrition.

  1. The book also explains how, as an inhabitant of the Solar System, Earth’s climate is influenced mainly by our Sun, and that should come as no surprise.

    But are changes to earth’s climate influenced mainly by our Sun?

    Are we so desperate to get rid of dodgy science that we’ll clasp to our breasts any other dodgy science that comes along?

    Is it still OK to say, “We don’t know?”

    • Ask those dodgy folks that run greenhouses for a living. They use devices to increase CO2 in, well, inside the greenhouses. Seems plants consume so much of the stuff in the greenhouses there’s simply not enough to keep them fed without pumping it in. I’ve read they even have greenhouses in every clilmate on Earth. Saying you don’t know would be very good for some.

      Oh, and it’s all been “political” for the Greens, not “dodgy” else we’d have put the alarmist up in the attic with all those crazy aunts and uncles.

      • Yes, and then ask those same good folks how much longer they leave turning on the heating at night in the CO2 enhanced greenhouses vs the non-enhanced. If your experience is the same as mine, they’ll tell you they turn it on in both at the same time.

        This is the closest thing we have to a real-world experiment, and despite CO2 levels 3 times greater than background, it can’t even trap more heat in a proper greenhouse.

    • If you can think of another source of energy like the sun, but unseen, then carry o n your belief but if the sun is the only major input then it is the major influence.

      • Earth’s climate is influenced mainly by our Sun but are changes to Earth’s climate is influenced mainly by our Sun?

        The sun doesn’t change that much. It needs an amplification mechanism (Svensmark, maybe?) but we haven’t evidence that there is an amplification mechanism.

        Let’s be sceptical about everything.

      • @johnmarshall

        You forgot about outputs, which is precisely what the greenhouse effect is alleged to inhibit. Energy added to the system is inputs less outputs…

      • The world has warmed since the little Ice Age. There’s lots of historical evidence for that.

        It just hasn’t warmed as predicted by the climate models under the forcing of the known CO2 emissions.

        I’m sceptical about the entire temperature record being entirely wrong. Measurements are real.

      • To claim that we have temperature records for hundreds of years, which are accurate to within tenths of a degree is complete nonsense. Even to within ±2ºF is highly questionable.

        “Measurements are real” means modern, empirical measurements. That is the only reliable metric. They show a small fluctuation of only about 0.7ºC over the past century and a half. That is hardly something to worry about. Rather, we should be very glad it is such a tiny fluctuation.

        And CO2? That beneficial trace gas has risen from 3 parts in 10,000, to only 4 parts in 10,000 over the same century and a half. It is insane to deconstruct our Western carbon-fueled civilization on the basis of those minuscule numbers. The people promoting the ‘carbon’ scare are either self-serving rent-seekers, or insane lemmings along for the ride over the cliff. Reasonable people should send them both packing.

    • ‘Is it still OK to say, “We don’t know?”’*
      It’s not just okay, it’s essential. Thanks for the reminder.

      ‘Are we so desperate to get rid of dodgy science that we’ll clasp to our breasts any other dodgy science that comes along?’
      Depends on whom you mean by ‘we’. Not Anthony, not you and me, not the majority of sceptics, not the majority of STEM educated CAGW faithful.
      Yes, apparently, the individuals who wrote this book.* Yes, some individuals who read this blog. The same as with every blog. There’s some people here because of their understanding of politics, some from their understanding of religion, some from misunderstanding of science, some from ignorance, some from curiosity, some from superstition, Anthony’s generous commentating policy lets almost all comment be heard, including that from the wildly wrong. This is a good thing.
      It’s error alone that needs censorship, the truth can stand on its own. It’s why you can’t trust Tamino’s blog. However plausible his posts, you are never able to tell if there is some counter-argument that utterly destroys his claims that he isn’t letting you see.
      Anthony’s drawing the book to our attention is also a good thing. It’s interesting in its own right that there is a popular accessible book, endorsed by some scientists, that runs counter to the current narrative. This book may be the first time some people encounter the idea that Thermaggeddon is not necessarily inevitable. Not everything in the book is wrong. While Warmistas will decry the whole book on the basis of any single error, we should decry error, but endorse what’s right.

      * Nevertheless, that is not to say that we know nothing.
      That the sun is the major influence on Earth’s temperatures is self-evident. That variations in the sun’s output cause variations in the Earth’s Climate looks to be an obvious corollary, until you attach numbers to it.
      We do know about Milankovic cycles, solar flares, Global Climactic Optima, and much more.

      ** I haven’t read the book. I don’t know for a fact it contains any errors. However, I haven’t seen that the authors of the book provide anything new related to solar climate dynamics. I’ve already dismissed most ‘solar climate theories’ on the basis the numbers don’t stack up.
      (I’m grateful to Willis Eisenbach for significant contributions to my understanding here. I have not yet dismissed Dr David Evans contribution, though I’m sceptical. I haven’t completely read it yet, let alone understood all of it, nor taken a reasoned stance on it.)

      • Thank you for the input
        I was, perhaps, too harsh in my critique.

        It just does seem to me that sometimes, “Anything but CO2″ is proclaimed.
        When it should be “Anything more reasonable than CO2 including random unknowns”.

        And I don’t rule out solar variations being the unknowns… but they are not known to be the unknowns (yet).

    • I don’t see anything wrong with the statement that the sun is a prominent factor in in our climate. As you point out, this is not the same as saying that the sun is responsible for the warming since the little ice age. It is essentially meaningless in that context, but not “dodgy.”

    • Is it still OK to say, “We don’t know?”

      It is more than ok. It is correct. It is respecting the Scientific Process.

    • @Peter Grace

      I post a number of press releases from alarmists that are also rubbish. Doing so gives everyone a chance to investigate and dissect it.

      • Speaking of rubbish, Peter Grace tries to resurrect the old “ocean acidification” canard.

        Mr. Grace needs to do a search, and read the extensive debunking of that false alarm right here, in articles posted in the last couple of years. David Middleton did an especially thorough deconstruction of that nonsense.

        CO2 has been up to twenty times higher in the geologic past, without the claimed “ocean acidification”. That is due to the oceans’ immense buffering capacity. Grace needs to get up to speed on the subject.

      • You said “I post a number of press releases from alarmists that are also rubbish. Doing so gives everyone a chance to investigate and dissect it.”

        Thank you! Your not being afraid to present opposing/”somewhat oppposing” viewpoints is EXACTLY why I started coming to your site- and EXACTLY why I am hooked. That, and the fact that you manage to keep the conversations intellectual (unlike the ridiculous comments being made on most the MSM sites). Your commentors are lively and intelligent (much helped by the choice in topics) – ALWAYS worth reading! I’m beyond grateful!

    • “….You know it’s rubbish.” Oh really! See this graph from the Warmists at SkS. Geologically we are currently at the low end of co2 in our atmosphere.

      • @Peter Grace,

        Your baseless assertion has zero value. Really, you know nothing. All you are doing is attempting another head fake. That is no longer effective.

        The rise in CO2 has been, on balance, a net benefit to the biosphere, causing no global harm — thus, it is literally ‘harmless’.

        And as Jimbo has posted, the added CO2 has brought about an 11% greening of the planet. So it is also beneficial.

        Your alarmist attempts to scare the public are just like the little lying boy who cried “Wolf!” After a while, you lose credibility.

        There is no wolf. And there never was.

    • Here is something interesting for you Peter Grace. As you say it really is all rubbish.

      Impact of CO2 fertilization on maximum foliage cover across the globe’s warm, arid environments

      Satellite observations reveal a greening of the globe over recent decades. The role in this greening of the “CO2 fertilization” effect—the enhancement of photosynthesis due to rising CO2 levels—is yet to be established. The direct CO2 effect on vegetation should be most clearly expressed in warm, arid environments where water is the dominant limit to vegetation growth. Using gas exchange theory, we predict that the 14% increase in atmospheric CO2 (1982–2010) led to a 5 to 10% increase in green foliage cover in warm, arid environments. Satellite observations, analyzed to remove the effect of variations in precipitation, show that cover across these environments has increased by 11%. Our results confirm that the anticipated CO2 fertilization effect is occurring alongside ongoing anthropogenic perturbations to the carbon cycle and that the fertilization effect is now a significant land surface process.

      A Global Assessment of Long-Term Greening and Browning Trends in Pasture Lands Using the GIMMS LAI3g Dataset

      Our results suggest that degradation of pasture lands is not a globally widespread phenomenon and, consistent with much of the terrestrial biosphere, there have been widespread increases in pasture productivity over the last 30 years.

      Analysis of trends in fused AVHRR and MODIS NDVI data for 1982–2006: Indication for a CO2 fertilization effect in global vegetation

      …..The effect of climate variations and CO2 fertilization on the land CO2 sink, as manifested in the RVI, is explored with the Carnegie Ames Stanford Assimilation (CASA) model. Climate (temperature and precipitation) and CO2 fertilization each explain approximately 40% of the observed global trend in NDVI for 1982–2006……

      The causes, effects and challenges of Sahelian droughts: a critical review
      …….However, this study hypothesizes that the increase in CO2 might be responsible for the increase in greening and rainfall observed. This can be explained by an increased aerial fertilization effect of CO2 that triggers plant productivity and water management efficiency through reduced transpiration. Also, the increase greening can be attributed to rural–urban migration which reduces the pressure of the population on the land…….

      A model-based constraint on CO2 fertilisation
      Using output from a 671-member ensemble of transient GENIE simulations, we build an emulator of the change in atmospheric CO2 concentration change since the preindustrial period. We use this emulator to sample the 28-dimensional input parameter space. A Bayesian calibration of the emulator output suggests that the increase in gross primary productivity (GPP) in response to a doubling of CO2 from preindustrial values is very likely (90% confidence) to exceed 20%, with a most likely value of 40–60%. It is important to note that we do not represent all of the possible contributing mechanisms to the terrestrial sink. The missing processes are subsumed into our calibration of CO2 fertilisation, which therefore represents the combined effect of CO2 fertilisation and additional missing processes.

      • Michael you know full well why it’s rubbish, however for those who are new to this issue I’ll give a brief explanation.

        The earth has an energy I/O imbalance. It’s measurable via the ERB satellites.

        It’s a matter of settled science that CO2 traps long wave radiation reflected from the earth’s surface and reradiates it, much of it back onto to the earth’s surface.

        GHGs make life possible on earth and CO2 is a significant GHG.

        GHGs also make life impossible on Earth’s closest neighbour, Venus. It’s atmosphere is mostly CO2. Its fairly constant surface temp is upwards of 450 degrees C. The green house effect has made Venus the hottest planet in our solar system.

        Increasing the CO2 in the Earth’s atmosphere will continue to increase plant growth – that’s happening right now – but it will also increase surface and water temperatures triggering rapid positive feedback from multiple sources.

        We know that releasing additional CO2 has the potential to be catastrophic.

      • It is widely accepted that CO2 is a greenhouse gas. However, the catastrophic extent of this effect is not clear at all from the available evidence. It is still perfectly possible to maintain that CO2 is, on balance, beneficial.

      • Michael Palmer,

        The only thing that is ‘rubbish’ is the attempted demonization of CO2 — a trace gas that is every bit as essential to life on earth as H2O.

      • @ Michael Palmer
        I omitted to mention ocean acidification. Even Greg Hunt the Australian federal Minister for the Environment who is an AGW skeptic and who had carriage of the legislation to end carbon pricing in Australia acknowledges the dangers that acidification poses to the food chain. Do you know of any good science being done that refutes
        1. That CO2 dissolved in the oceans lowers their pH?
        2. That this increase in acidity endangers calcifying organisms which in turn could then endanger the food chain ?

      • Peter – the same answer applies. In principle, yes, adding CO2 to the oceans should lower their pH. However, this effect is not even measurable yet. If the incremental CO2 causes more calcium to stay in solution, this will raise the pH again. All that is going to happen is a slight shift in some chemical equilibria.

        It should be possible to determine the severity of this potential problem in laboratory models without too much trouble. Has this been done? I haven’t read about it.

      • I agree with Peter Grace right up to his innumerate, hand-waving, foolish pseudo-comparison “…GHGs also make life impossible on Earth’s closest neighbour, Venus”. At that point we rapidly part company.
        Venus’s atmosphere is 96.5% CO2. Earth’s atmosphere is 0.04% CO2. The ratios are absurdly different. It’s no more sensible than suggesting that since bathwater temperature of 96.5 degrees C would kill you, then bathwater above 0.04 degrees Centigrade is bad for you.
        That’s also ignoring other serious differences.
        Venus has 92 bars of atmospheric pressure at the surface. Crucially, it also has 1.93 times the Solar Energy input that Earth does, an amount that without GHG’s would still give it a temperature of 500K.
        Likewise, when it comes to the acidification of the oceans (“Nobody really thinks it will actually become acidic” said Senator Tim Wirth, demonstrating profound ignorance of his electorate.) The articles cited by David Middleton demonstrate to the satisfaction of every reasonable person that the anxiety is irrational.

      • @Leo Morgan I was not using Venus as a “this is what the Earth will look like” device. I was using it as an explanation of GHGs.
        How do you support you claim that without GHGs Venus would still be a hot planet ?

        Wouldn’t the Venus nights, sans atmosphere, be as cold as a witch’s tit ?

  2. This is basically a book that cover most of the stuff that should be tought/learned in late primary school (7th- grade), some even earlier. At least it used to, when I was at that age during late 1970’s …

  3. A few decades ago when we first encountered the thermageddon gospel, I wrote a reaction in a local paper on my work. I too, was concerned with CO2. The other way around though. Seeing the massive limestone mountains and rock formation, all based on CaCO3 (calcium Carbonate) and coal deep in the crust, It occurred to me that these were quite a (semi-) permanent sink in the carbon cycle.

    Any cycle dies when something stops it in midair and I envisoned that in so many hundred of million years, all carbon would be either in limestone or in coal in the crust. Only volcanism would be a vector to return some of the carbon back to the global cycle but it seemed not enough. The gradual loss of useful carbon would diminish life on earth and obviously the very low CO2 values in the Pleistocene supported this idea.

    So I concluded that mankind was doing a great service to the living planet by returning much of the lost carbon in fossil fuels back to the global carbon cycle.

    However nobody seemed to understand.

      • This is seriously unserious stuff. I know that no site can control crazy postings but there is too much of this stuff on WUWT

      • Not sure what Mr. Grace was commenting on, but, the post by Sun Spot looks pretty “unserious.” Symbiotic relationship with a planet? And then too, what might “re-carbonization” refer to?

  4. Have read Cliff Ollier’s geo views many times over the years, he’s not afraid to tell it as it is, and there’s so much to tell which rarely gets a clear voice. Thanks cliff.

  5. This one is sure to get the likely suspect’s knickers in a wad. It will start with personal attacks on the authors, no doubt.

    • Not really. Ol’ Pete above is waving his arms like one of those giant plastic air men at a car wash. Not one useful rebuttal, no examples, just arm waving. I’m surprised he’s not using all caps to yell at everybody. As if his opinion is useful in a scientific discussion. CO2 is good.

  6. The scare of increased CO2 creating a Venus like runaway temperature increase began in a big way with Jim Hansen of NASA. He oversaw the probe to Venus and predicts our oceans will boil away as ‘may’ have happened on Venus. Of course Venus is extremely closer to the sun. Some scientists maintain the first extintion of life on Earth, about 95%, was caused by massive release of CO2 from huge eruptions in the now Siberian region. However, even if we were to continue using coal for another 5 centuries IMHO I doubt the level of CO2 would dupicate any thing like Venus or the extinction event.

    • Temperature on Venus is little to do with distance to the sun. It’s the weight of that atmosphere that is the cause of the temperature.

      • No, it isn’t the weight of the atmosphere that causes that temperature.
        If it was, I’d just get a pile of rock that weighed as much as a column of Venus’s atmosphere, connect it to a thermocouple, and generate energy ever after.
        While you can generate heat by compressing something from less dense to more dense, it doesn’t keep on generating heat thereafter.

    • Neville,

      Numerous sources -google Venus Vicky Hanssen (irony)- show that the surface of Venus has been extremely hot in the past, like 1000Kelvin while it’s only about 740K now. Wouldn’t that suggest that there may have been another heating mechanism for Venus other than runaway greenhouse effect?

      • Empirical data alone rules out the possibility of a “run-away” greenhouse effect (RAGHE) due to CO2. See the graph above posted by “Jimbo August 27, 2014 at 7:30 am” He cunningly chose to source it from SkS, but the data source from which they grabbed it is well the well respected “Geocarb III.” The late Carboniferous levels are 16 times current levels. Since there no RAGHE then, nor did one occur Mesozoic when CO2 reached about five time current levels, there is no possibility of such an outcome now either, QED.

      • Duster, the IPCC rules out the runaway greenhouse effect on Earth as does one of the IPCC insiders.

        “Some thresholds that all would consider dangerous have no support in the literature as having a non-negligible chance of occurring. For instance, a “runaway greenhouse effect” —analogous to Venus–appears to have virtually no chance of being induced by anthropogenic activities…..”


        Sir John Houghton
        Atmospheric physicist
        Lead editor of first three IPCC reports
        There is no possibility of such runaway greenhouse conditions occurring on the Earth.”

        [Full paper paywalled]

    • I am not sure that Jim Hansen started the runaway greenhouse effect. I think that it was started by Carl Sagan in his disputes with Immanuel Velikovsky. To recap for those who are unaware, IM considered Venus a new addition to the solar system, having been ejected from Jupiter, and hence retaining much of the heat that Jupiter’s core would have. CS borrowed the work of Rupert Wildt, who predicted that Venus would have a raised temperature, possibly as much as 100C, on the basis of greenhouse, and declared that the raised temperature of Venus was entirely due to greenhouse, and that if we increased the CO2 content of the earth’s atmosphere we would be in danger of an uncontrollable runaway greenhouse effect, and end up like Venus.

      A question (actually, several) for those interested – if all coal, oil and gas were burnt and the resulting CO2 retained in the atmosphere, and if all the CO2 contained in the chalk, limestone and marble were returned to the atmosphere, what would then be the quantity of CO2 in the atmosphere? As much as Venus’s? Half? Double? Would we then risk a runaway GE? Could we manage to burn all that carbon, and release all that CO2?

      • Does anybody know what the RAGHE threshold is deemed to be, and should we be using Venus’ RAGHE as the exemplar?
        Venus appears to have a reasonably constant temperature so I’m guessing that the CO2 levels have not changed much during man’s short observation of the planet.
        Could it be that (grabbing a figure from the air) 500ppm, consequent albedo loss and hydrate release could tip our planet into a cooler RAGHE with just a 5C warming? If not why not?

  7. Err… China had starvation problems up to the 80s, until they losened their idiodic production plan policy.

    • Mao in China allowed the deaths of about 50million people…when there was enough food to feed all. That was in the 50’s.

  8. The pendulum of understanding swings into outlier territory in direct reaction to the opposite outlier. Each extreme proclaiming the stupidity of the other, not recognizing themselves in the mirror of reflection. Silly.

    • I had exactly the same thought a couple times in the last days. Maybe it’s the new format. The challenge has always been to stay sane when the whole world goes crazy.

  9. Considering that the most important parameter to population control is wealth, increasing CO2 and at the same time extract the energy to build more advanced societies must be priority #1. The CO2 reduction madness that the current agenda tries to impose will not only lead (if it succeeds) lower agricultural productivity but also to continued population growth and eventually starvation.

  10. I can think of several family members who should definitely read it. I doubt they would, though.
    The Warmist memeplex is a powerful one. I yearn for the day they realize they’ve been duped. Sadly, that day is probably a few years away yet. Climate is still a taboo subject.

  11. M Courtney says
    “The sun doesn’t change that much.”

    TSI doesn’t change much but the components of TSI do. If a recipe for biscuits didn’t differentiate between flour, sugar, and baking powder; merely referring to them all as white powder, that’d be a recipe for some bad biscuits.

    Also, it’s not just the variation in the sun’s energy but the variation in the sun’s energy introduction into earth’s system. Energy from the sun applied to the Northern Hemisphere has different effects with respect to near surface temperature than the same energy applied to the Southern Hemisphere.

    • Good points.
      But it isn’t proven yet.

      My position isn’t as hard on solar effects – powerful or irrelevant – as the article implies is the position of the authors of this book.

      This stupid threaded reply system means that comments and so nuance are lost. I’m struggling to keep up and so keep getting drawn in left, right and centre.
      I hate these threaded comments.

      • It’s a little early to throw the baby out with the bathwater Mr. Courtney. I recently reset up my computer front page. It took me a week to realize I liked the new set up better. Let’s give this new front page for WUWT a fair shot. Jo Nova site uses threaded comments very successfully.

  12. It is estimated that life has been sustained on Earth for about 4 billion plus years, some say 4.5 billion. A remarkably stable ecosystem. This in spite of the concern some show for temperature “anomalies” of fractions of a degree or even several degrees over long periods of time. History shows that life has flourished in the warmer times, while in the colder times, not so much. Much time is spent in climate “science” swatting at mosquitoes with ridiculous statistical masturbation sledge hammers and inventing mosquitoes where none exist. Much of it to pump up egos and, of course, to make, or steal, money.

  13. Thanks for the news. I hope this book gets read.
    I abhor the idea of CO2 as a pollutant, making all living creatures polluters per se, and consumers of pollution. This makes pollution a meaningless word.
    Regarding the Sun, I think Svensmark is right and his experimental data shows it.
    It looks like the Total Solar Iradiance is the energy flow, quite constant, and the magnetic field does the modulation of cosmic rays that seed clouds.

  14. What! The book is only available in paperback with no kindle\ebook version. These guys are obviously tree haters and i’d guess that the supply chain (making paper, printing and shipping) contributes carbon to the atmosphere too

  15. So far we have much data (both in the natural environment as well as in Green Houses) that shows the increase in CO2 has been beneficial and none that it has been bad. To say that increases in CO2 being beneficial is far from Rubbish based on the data we have so far.

  16. Not too much news to me but I am very pleased the new book seems to be getting noticed.
    Anyway this what I have been saying for a number of years now. One does not need a PhD to figure these things out, a little empirical data goes a long way.

    A concentration of about 1,000ppmv would be beneficial to life on earth, this being the concentration that Glass House growers prefer,*cWuzeO4qmDVbgA_/Greenhouses.CarbonDioxideInGreenhouses.pdf
    Our exhaled breath is about 4500ppmv
    Up to 5000ppmv is acceptable for work places (American Conference of Governmental Industrial Hygienists.).
    Up to 3000ppmv for residences (Canadian exposure guideline for residential buildings)”
    Medical oxygen has between 10,000 ppmv and 20,000 ppmv in it.

    (Look up Oxygen medical and note it has up to 20% CO2 added (20,000 ppmv))

    Furthermore, some scientists credit the extra CO2 in our atmosphere as the reason for our increased food production.

      “The last time carbon dioxide levels were apparently as high as they are today “” and were sustained at those levels “” global temperatures were 5 to 10 degrees Fahrenheit higher than they are today, the sea level was approximately 75 to 120 feet higher than today, there was no permanent sea ice cap in the Arctic and very little ice on Antarctica and Greenland,” said the paper’s lead author, Aradhna Tripati, a UCLA assistant professor in the department of Earth and space sciences and the department of atmospheric and oceanic sciences.

      “Carbon dioxide is a potent greenhouse gas, and geological observations that we now have for the last 20 million years lend strong support to the idea that carbon dioxide is an important agent for driving climate change throughout Earth’s history,” she said.

      • “carbon dioxide is an important agent for driving climate change throughout Earth’s history”

        Contrarians believe that CO2 rises in response to warming oceans, after a 800-year lag.

      • Peter Grace,

        Have you ever heard of a coincidental correlation? CO2 is not a measurable cause of changing temperature; it is the result of changing temperature.

  17. @Peter Grace
    “Venus. It’s atmosphere is mostly CO2. Its fairly constant surface temp is upwards of 450 degrees C. The green house effect has made Venus the hottest planet in our solar system.”

    The fact that Venus sits much closer to the sun has probably nothing to do with the higher surface temperatures.

    • Peter Grace:

      I am interested in planet Earth and not Venus.

      Nobody disputes that carbon dioxide (CO2) is a greenhouse gas (GHG) but of itself that does NOT suggest an increase to atmospheric CO2 concentration will have a discernible effect on the Earth’s complex – and water-dominated – climate system.

      To date there is no evidence – none, zilch, nada – that increases to atmospheric CO2 concentration since the industrial revolution have had any effect on the Earth’s climate. Three decades of research conducted worldwide at a cost of over US$5 billion per year has failed to find any such evidence. In the 1990s Ben Santer claimed to have found such evidence but it was soon discovered that his so-called “fingerprint” was a result of his having selected a short sequence from part of a data set.

      Please publish any evidence you have for a discernible effect of increased atmospheric CO2 concentration on the Earth’s climate since the industrial revolution. Your publication would certainly obtain at least two Nobel Prizes.


  18. John,

    That is entirely too sensible, and it leaves no room for crazies to blame CO2.

    On another thread I was told that Venus is hot because of its high albedo. So, it reflects a lot of energy away — but that makes it hotter? Alarmists don’t think things through before putting their brains in gear. Really, if Peter Grace is any indication, they have no brains.

  19. A reminder of what G S Callendar wrote as the conclusion of his famous 1938 paper on carbon dioxide and warming:

    “It may be said that the combustion of fossil fuel, whether it be peat from the surface or oil from 10,000 feet below, is likely to prove beneficial to mankind in several ways, besides the provision of heat and power. For instance, the above mentioned small increases of mean temperature would be important at the northern margin of cultivation, and the growth of favourably situated plants is directly proportional to the carbon dioxide pressure. In any case, the return of the deadly glaciers should be delayed indefinitely.”

    Looking at the new book on Amazon, I see they have included the last bit of this quote and the fact that Callendar thought CO2 beneficial.
