Climate Change Deniers Herald the Melt on Mars

(Facetious) Congratulations to National Geographic  for having turned up another apparently credible climate change denier tucked in a far corner of the world.

Admittedly, NatGeo reports that Russian astronomer Habibullo Abdussamatov is "completely at odds with the mainstream scientific opinion" when he argues that a recent melting on Martian icecaps proves that global warming is caused by the sun's rays. But Abdusssamatov gets the headline, while the overwhelming majority of credible astronomers are relegated to the second page of the NatGeo website.

It is yet another example of the media's preoccupation with lonely (sometimes looney) voices. No wonder the public remains convinced that the scientific community is still locked in a legitimate debate over climate change. When a journalistic institution like National Geographic is this careless in presenting the science, how can casual observers hope to make informed conclusions?

What's next?

"Denier" Label

Johan, you use the term "IPCC dogma". Is there any difference? You are also trying to belittle your opponent. I'm surprised that you don't see that.

Actually, I too found Richard a bit quick to dismiss this guy as a crank, wihtout evidence either way... But that shouldn't distract from this post's main point, which does demonstrate a legitimate issue--the popular press not putting this guy's views in their proper context, and thus potentially (ok: probably) lending far too much credence to something that amounts so far to just a pet theory.

Anyway, it puts the lie to the deniers' thesis that the mainstream media loves AGW. No, like Hollywood, what it loves is a "maverick". The mavericks once tended to be on the AGW side, now it's the reverse...

It also puts the lie to the deniers' thesis that AGW theory is all about getting attention and thus grant money. Who do you think would have more to gain financially by appealing to the popular press? Someone in a marginal position who is not taken seriously by the journals? Or someone who claims that "the debate is over"?

Grant Money

I'm not aware of any climate scientist ... pro or con ... who has claimed that the debate is over or the science settled. That statement "... the science is settled ..." first appeared in (I believe) a New York Times article when the first IPCC report was issued and it was a reporter, not a scientist, who made it.

The overwhelmingly largest contributor to climate research is government and governments react to public opinion. Witness Steven Harper's or George Bush's recent "conversions".

The ones with the most to gain are therefore those who can convince the public that there is a serious (critical, catastrophic, world-ending, etc.) threat facing us. More money is urgently needed NOW if it is to be averted. The ones that are, as you say, in marginal and ignored positions and who say that the problem is minor or cannot be addressed other than by adaptation will get no money.

the science is settled

BCH, if by "the science is settled", you mean a 100% perfect knowledge of everything relating to the climate, then you're right: no scientist is saying that. But that's a red herring often put forward by the "skeptics". The real issue is and has always been: is there enough compelling evidence to take action. It's not a matter of certainty, but a of risk assessment. While fairly obvious, this concept is too subtle to be included in what passes off as "debate" in this issue.

Anyway, plenty of scientists have said that it's time to take action, as you'll find here. There's little in this release that would suggest a bonanza for climate researchers, certainly nothing that would justify them risking their credibility should this climate thing be an ill-though-out hoax. In short, there's no money trail that I can see, leading from a suggestion that "the time is ripe for action".

In fact, the only money trail I can see is the one running from those who say that the bigger picture is unknown, and needs to be studied a lot more before there's a case for taking action. I'm not saying that this is in fact their motivation, just that the logic of grant funding leads to the "skeptics", not the "consensus".

I'd like to stress that this is not about "certainty", but risk assessment. Of course we shouldn't act too soon, but it's equally obvious that we shouldn't act too late, either. As with all important things in life, at a certain point we NEED to make a decision, and that's usually before we're 100% certain. The term Skepticism is often used incorrectly. Some "skeptics" are just avoiding making a proper analysis and taking a difficult decision. Others are using the term to conceal various prejudices, or use it as a shield to hide behind as they take potshots at supposed "environmentalists" or "loony lefties". Skepticism is a process, not a position.

Global Warming

First a couple of quotes “There is no such thing as consensus science. If it's consensus, it isn't science. If it's science, it isn't consensus. Period.” Michael Crichton “Science is not democratic: even if the majority of the scientific establishment subscribes to a particular view, this does not automatically make it right.” Martin Livermore, Cambridge, UK "Skepticism is the first step toward truth" Denis Diderot philosopher I have a few questions ... If you really, really believe anthropogenic atmospheric CO2 is the cause of the fraction of a degree Celsius global warming since 1860, then explain to me the following 1. Why was the earth in a cooling cycle between 1940 and 1980 whilst CO2 levels were soaring? Remember, in 1975, when the Church Of Latter Day Alarmists was warning of a coming ice age? 2. Why has the global mean temperature peaked in 1998 and actually dropped slightly since then whilst CO2 levels were soaring? Could it be that we are now entering a new cooling cycle, or maybe even a new ice age? 3. Why did the global mean temperature not start rising until at least 1910 despite rising CO2 levels since at least 1750? 4. Why does the graph of global mean temperature since about 1860, bear absolutely no relation to steadily increasing levels of CO2? Could it be that there is NO CAUSAL RELATIONSHIP? Regards

There is a causal relationship

Bonzo said "Why does the graph of global mean temperature since about 1860, bear absolutely no relation to steadily increasing levels of CO2? Could it be that there is NO CAUSAL RELATIONSHIP?"

But you are wrong Bonzo, there is a causal relationship between increasing CO2 concentrations and retention of IR radiation. There seems to be a believe out there that this IR retention thing is something invented by climatologists. In fact, it is basic physical chemistry and was first identified over 100 years ago. So if the hundreds of thousands of climate scientists are part of an "AGW conspiracy" so are the much higher numbers of physicists and chemists who would have to be part of the conspiracy too. I don't see any of them coming out and saying the CO2 does not absorb IR radiation at certain critical wavelengths.

Causality

Bit if a bait and switch there Ian. The observation was about the CO2-Temperature correlation. Not CO2-IR absorption.

No one disputes that CO2 absorbs re-radiated IR at certain frequencies. Given that fact and the conclusion from AGW theory that CO2 is the dominant driver for global warming, why does the temperature of the atmosphere over the last 100 years not track the rising CO2 concentration?

Lots of explanations have been proposed; aerosols masking the heating; ocean heat storage; natural delays beause the atmosphere doesn't react instantaneously; land use changes; CO2 really isn't all that important; etc.

Fact is ... we have some untested (and largly untestable) hypotheses but no one really knows. Why is that so hard to say?

Not a bait and switch

BCH, you said that there was no causal relationship between increased levels of CO2 and global temperature. This is not true since there is a proven scientific reason that increasing CO2 concentrations lead to increased temperature (the IR absorption by CO2)

Maybe you meant something different by "causal relationship" than is commonly understood. If so please explain what you meant by "no causal relationship".

As for temperature not directly following CO2 concentrations, all climate scientists are in agreement that CO2 is not the only driver of climate. Other factors, contrary to what AGW deniers always claim, are factored in. Their contributions are known with pretty good accuracy (except for aerosols) and they can only account for minor changes in global temperature.

Causality

I didn't utter (or type) the phrase "no causal relationship". I did acknowledge that CO2-IR absorption is a well recognized physical process. What I did say was that there is no firm explanation for why temperature and CO2 concentration do not track over the 20th century.

The "other factors" is really the problem. According to chapter 2 of the IPCC Fourth Assessment report, the current level of scientific understanding is

CO2 and other Trace GHGs High

Ozone Medium

Stratospheric water vapor Low

Land Surface Albedo Very Low

Aerosol Direct Effect Low

Aerosol Indirect & Clouds Low

Contrail Cirrus Low

Solar Medium

So we have confidence that we have a firm grasp of only one of eight possible drivers; a moderate understanding of two more and, as I interpret it, no useful predictive ability for over 60% of the factors that may affect climate.

Note further that the list may not even be complete. Water vapor and recent observations about cosmic rays are not even on the list. Recent research out of Denmark and Sweden may also indicate that we don't know as much about the solar contribution as the "Medium" rating would suggest.

Far from "pretty good accuracy", their contributions are only approximated. Not only is their magnitude not known with any confidence but we cannot even be sure of the sign of their contribution in some cases.

You did type it

I get annoyed when people say one thing then when they are criticized for it they deny it. You typed, "Could it be that there is NO CAUSAL RELATIONSHIP". Now you can twist meanings but the majority of people reading that would take it that you are trying to deny that there is a causal relationship.

As for the other forcing factors, you are either misunderstanding what the IPCC said or again are trying to distort what they said. These forcings are not well quantified but they are known to be of small consequence. How do we know that? Well the models only fit when they are given a small role. Now don't start saying that "computer models are useless" because you would be completely wrong. The reason that we can be so sure on what is causing global warming is that model predictions are only able to accurately (don't believe what the AGW deniers are saying) describe the changes when these forcings are of a low order of magnitude.

The cosmic ray theory has been shown to be wrong so your arguments just don't stand up to critical review (after all, that is what science is about).

So tell me, since you do not accept the science as agreed by the IPCC, just what do you think is causing this unprecedented rate of temperature increase. Come on, you must have thought about it so please let us all know what all the scientists have missed.

Annoyed ...

Apparently not annoyed enough to go back and actually read my (i.e. BCH) post. I believe that Bonzo is the one that typed it.

Subject to typos, and I've just checked, that comes from the IPCC chart in Chapter 2 and it is accurate. I typed everything in their chart and didn't change anything. As to interpretation ... what part of 'Low Scientific Understanding' is giving you a problem? It seems to be you that is unaccepting of the "science behind IPCC".

I've been doing computer stuff for decades ... a lot of it modeling. Sorry to break it to you but models are not reality and they are not even data. Your comment is telling though.

By making adjustments to factors that they admit to not understanding they managed to produce the result that they wanted. I do notice that the one parameter that they didn't change was radiative forcing associated with doubling CO2 to values that are more in line with what real experiments indicate that they are. If they had they could also have replicated the history they were trying to match. Of course, if they did that then CO2 wouldn't be such a big deal and we can't have that, can we?

Cosmic ray theory has been disproven? Really? In what paper? At the moment it is just the subject of two papers by Nir Shaviv and Jan Vizier demonstrating a link between climate and cosmic rays over long geological time periods. To my knowledge, no one else has completed any research on the topic and certainly haven't refuted it.

To quote from my earlier post, no one (pro or con) has a clear and fact-based explanation for why CO2 and 20th century temperatures don't track ... lots of guesses but no facts. Was that something else that you didn't quite get around to reading?

One turnip is just like another

"Apparently not annoyed enough to go back and actually read my (i.e. BCH) post. I believe that Bonzo is the one that typed it".

When you are wading through a field of turnips one just looks like another. If you people want to be treated in a non-prejudicial manner then read up on some science first before you start telling all reputable scientists that they are wrong and you know better.

As for Shaviv's and Veizer's papers then I suggest you read the comments on realclimate.org. There is more than just a hint of scientific malfeasance associated with those two's work.

http://www.realclimate.org/index.php/archives/2005/05/on-veizers-celestial-climate-driver/

http://www.realclimate.org/index.php/archives/2005/01/peer-review-a-necessary-but-not-sufficient-condition/

You also said "to quote from my earlier post, no one (pro or con) has a clear and fact-based explanation for why CO2 and 20th century temperatures don't track ... lots of guesses but no facts. Was that something else that you didn't quite get around to reading"?

Well try reading some scientific papers (start with the various AR's from IPCC) and you will find that you are wrong. The factors you mention have been looked at and have been relegated to only minor factors in the recent unprecedented rise in global temperatures. As I mentioned previously, the models fit the actual temperature measurements, both looking forward and looking backwards (from about 1988).

Realclimate ...

Thank you Ian. I read the Realclimate posts some time ago.

The first one is a well-reasoned critique of a Veizer paper that is not the same one as the Shaviv/Veizer paper that I referenced. I agree with Realclimate that the paper they are describing has some serious issues to be addressed.

The second seems to be an attack by Michael Mann on virtually everyone including Shaviv, Veizer, Pat Michaels, Willie Soon, Ross McKitrick, Chris de Frietas and Fred Singer. His comments specific to the Shaviv/Veizer paper were derived from criticisms published by Rahmstorf et al. and responded to by Shaviv in the same journal.

Both the criticisms leveled by Rahmstorf et al. and the responses by Shaviv are extremely technical and are beyond the scope of this site (or my mastery of the details of astrophysics which is where much of the discussion takes place). All this is as it should be. Shaviv's proposal presents a significant change in perspective and other scientists are trying to pick it apart which is exactly what they are supposed to do.

At best, the cosmic ray / global warming link must be regarded as tentative and subject to further investigation.

The problem is that there is no correlation

BCH, cosmic rays are an interesting area of study. Unfortunately, there is no correlation between cosmic ray flux and temperature change over the last 100 years or so. There may be a correlation on a cycle of aprox 500 million years but that is not the timescale that is of interest in AGW.

If you have data that proves me wrong please present it.

As for the 11-year solar cycles well there is no discernible corresponding change in temperatures for that either.

Nigel Weiss, a prominent solar astrophysicist from the UK has looked at solar forcings and puts the amount of temperature change associated with solar changes in the past 100 years or more at about 0.2 degrees C. This is about what others have found for changes during the MWP and LIA thus solar forcing can be put forward as probably the main cause of these slight changes in background temperature change. However, the recent warming experienced over the past 100 years is much larger and is occurring at a much faster rate. The only factor that seems to fit the situation is the forcing by GHG's, CO2 in particular.

The dip around the middle of the last century is due to aerosols. All of this is well documented and accepted except by the small band of deniers who you keep quoting. That is why I get so annoyed. Start reading whole papers, not cut and paste highlights or improper interpretations coming from climatefraudit et al.

It’s all out there if you will just make the effort.

No correlation ...

Yes Ian. I know. I'm the one who told you that there is no indication of changes in cosmic ray intensity.

I've read Dr. Weiss's work among many others and the "consensus" (can I use that word?) seems to be that solar influences can account for some but not all of the warming of the 20th century.

Aerosols are the presumed culprit for the 1950-1980 cooling, based primarily on the fact that you can make the models work if you include them. Since there was no consistent monitoring of how much aerosols there were globally during that period, we are not able to back up the presumption of aerosol effects with data.

You might want to know that the "deniers" that I have been quoting are the IPCC Technical Report, Dr. James Hansen (the father of Global Warming), RealClimate and The National Academy of Sciences. Not a Ball or Michaels in the bunch.

It’s all out there if you will just make the effort.

BCH, the following graph

BCH, the following graph displays the causes of warming. Solar (and other natural variations) is only minuscule in its attribution to global warming. In fact, one can nearly cancel out all natural factors (or at least bring it down to 0.1 C of response) and say that human activities have caused the vast majority of the warming over the last century-and-a-half.

FOS is more of the fossil

FOS is more of the fossil fuel industry-funded hogwash and have no climate scientists with any real peer-reviewed publication history regarding climate change. They are a PR group, not a science group. Anyone who uses them as a scientific source rather than the IPCC, AAAS, NAS, Royal Society, CRU, NCAR/UCAR, or even NOAA are fools who have bought into far-fetched garbage similar to ideas like "aliens increase the level of gravity on Earth" or "the planet has been cooling since 1998."

The Graph ...

Thank you Stephen ... Yes, I've seen that one (or ones very like it.)

In essence the way that is derived is to program a GCM with likely values for all the forcings (the graph in the lower right on the same page) and then tune them until you get a history match. Pretty much standard modeling practice.

Ideally, you would like to be able then to go out into the real world, measure all those things, and confirm that what you put into the model is supported by real world data.

That's where all the controversy lies. Because we are dealing with an historical time period (i.e. the 20th century) the ways we have to measure things like aerosols, cloud cover, land use changes, surface albedo, solar activity, etc. are indirect at best and plain guess work at worst. That is not to say that the assumptions were wrong ... its just that we can't confirm from real-world data that they were right.

Even more critical to our understanding of model outputs is the question "Can we assume that the factors that worked for the 20th century will continue to work for the 21st?"

Just one example of some of the difficulties is Dr. James Hansen's modeling work where he used the assumption that oceans would warm as a result of AGW ... and sure enough, they did warm from the mid-eighties to about 2002. Then along came a study by Lyman etal saying that the oceans cooled between 2003 and 2005.

Now what? Is that just a temporary jitter in the trend? Is the assumption of ocean warming wrong? What (if anything) does it mean for model-generated predictions of future climate states?

You said the Lyman et al.

You said the Lyman et al. paper showed a cooling in the oceans. They actually said a cooling in the UPPER ocean.

The paper includes a map of observed temperature decreases in the upper ocean on page 11. Many of the areas in blue (areas with decreases in temperature) correlate well with the areas of the ocean over which tropical cyclones are spawned or perpetuated over warmer water.

As the years 2003 to 2005 featured alarmingly high tropical cyclone seasons, it can be said that it is likely that these tropical cyclones were a principal cause of the temperature reduction in the upper ocean as tropical cyclones take significant quantities of heat from the upper oceans to survive and intensify.

Cyclone cooling ...

I hadn't heard that theory before.

Hope someone does a paper on it.

Note however that "upper ocean" translates to the top 750 meters with evidence of it going much deeper (see page 5 of the report). That's a long way down for surface phenomena to have much effect.

The other issue I would wonder about is if tropical cyclones are sufficiently large or long lasting that they could account for a general cooling trend lasting (for the study period) two years.

The final "unknown" is that Lyman concludes that there has been a net heat loss 3.2 * 10^23 Joules. That's a lot of energy and it must have gone somewhere. Did it heat the atmosphere? Was it re-radiated to space?

All unknowns and nobody has the answers ... yet.

How much energy was "used up" melting the ice?

BCH said: "The final "unknown" is that Lyman concludes that there has been a net heat loss 3.2 * 10^23 Joules. That's a lot of energy and it must have gone somewhere. Did it heat the atmosphere? Was it re-radiated to space?"

I wonder how much of that energy loss has gone into melting the extra ice that appears to melting these days.

Anyone with any ideas or references?

Ice Melt ...

Interesting thought ...

It would have to have heated the atmosphere first and that in turn melted the ice because the cooling of the oceans, and therefore the heating of something else, does not appear in areas where there is ice cover.

The real problem with the ocean cooling is that AGW theory says that increasing CO2 heats the atmosphere and then the warmer atmosphere heats the ocean by convective heat transfer.

We know that CO2 is increasing but if the oceans are cooling, something must be broke in the middle. The Stefan-Boltzmann law, suitably modified for albedo and emissivity, says that CO2 must have the heating effect so that part probably isn't broken. The uncertainty that remains is that the presumed radiative forcing for CO2 heating used in most models is about 2.5 Watts/square meter. This is starting to look like numbers of about half that may be more appropriate.

Once again ... more research is needed.

Cherry picking at best

BCH, cherry picking is not part of the scientiic method. One must read all of a report and all of the many other reports, both pro and con before one can draw conclusions. Not all reports are correct, but science does a good job of weeding out the wrong stuff from the correct ones.

There is a very good example of how a very good scientist (Nobel Prize winner in chemistry) can have a paper published in a highly regarded journal (PNAS) and be completely wrong. I refer to the paper in PNAS which shows conclusively that DNA consists of a "triple helix". As just about everyone knows, DNA is a "double helix". So, quoting one paper in the multitude of papers (and cherry picking of single sentences) is not the way science works. Any graduate student using these tactics would not have his thesis approved, in fact it would probably be called academic fraud.

Cherry Picking ...

I guess we have a choice. Quote what seems to be the relevant part of a scientific paper or just make blanket assertions as to our beliefs with minimal or no attributions.

I have chosen the first of these. I "cherry-pick" only in the sense that it is impractical or impossible to post entire papers so I must quote something less.

Where did you get the notion that academic standards applicable for a graduate thesis should apply to, or are appropriate for, the discussions that go on here?

Liked the way that you slipped in "academic fraud". A little implication of malfeasance is always good where there is no actual evidence of it.

What does Linus Pauling have to do with anything?

... and he won two Nobel prizes.

There is a problem with your cherry picking

BCH, when you cherry pick statements and papers which disagree with the scientific consensus (and don't try and tell me that there is no consensus) and support the mutterings of a fringe band of non-scientists you are stepping outside the boundaries of how science operates. Of course you and your supporters are free to think what you want. What you are not free to do is to distort that which has been found to be the best scientific explanation. If you and the others can come up with some facts and data to back your case then we would get into a true scientific discussion. However, the only facts you can bring to the table are the cherry picks that in many cases do not say or prove what you try to make them out as saying.

As for the comment about graduate students, graduate school is, or should be, a training ground not for just scientific endeavours but moral and ethical ones as well. The conduct of science must be performed in a completely honest and ethical manner. Honesty in science is much more appreciated than scientific ability in many cases and science frauds are dealt with very seriously when they are exposed (Korean stem cell researcher). The reason for this is that if dishonesty was rampant in science we would not know whether a paper that was published in the peer reviewed scientific literature was true or not. It would be very easy for a scientist to write a completely passable paper using made up data. The peer review cannot differentiate between an honest publication and a fictitious one, only on the competence of the experimental method and whether or not the interpretation of data and the drawing of conclusions reflect what was found. Of course, if the work were important it would eventually be repeated and found to be not true. However, the majority of scientific work is never repeated since it would be difficult to publish something that already exists in the literature.

An example is a student who was working on the immunology of grafts. For a while, he convinced people he was working with, that he had a successful treatment to allow a white rat to accept an allo-graph from a black rat (it should be rejected) However, one day someone discovered that the black grafts were actually stains on the white fur put on with a black felt tip marker. The irony was that the student had top academic marks and had been accepted into a prestigious medical school for an MD degree. His career was in tatters before it even started.

As for my comments about Pauling and his “triple helix”, that was to show that the idea of two sides (two chains versus three) to any scientific argument is false. The scientific consensus has said that there is a “double helix” and that is what is accepted. See the analogy with AGW yet, BCH?

Outside the boundaries ...

I infer that "stepping outside the boundaries" equates to "not blindly accepting the proclamations of IPCC et al". Guilty as charged. Science to me is about impartially examining evidence and following where it leads ... regardless of who made the evidence available. Apparently for you, the quality of science is determined by who paid for the research or what personal opinions they have expressed. You are of course, entitled to that approach but it's not my understanding of how science works.

Of course there is a consensus. It is that we have very low scientific understanding of most of the factors that may potentially affect climate.

Why are you nattering on about graduate school? I've yet to see a thesis advisor that would say "He screwed up the science but we'll give him the degree because he got the moral and ethical issues right." Wake up. Scientific training is about the science.

Your example of the fraudulent stem cell researcher is telling. From what I remember of the story, he had a firm belief in the theory that stem cells were the answer to curing many ailments and it was therefore in the best interests of all concerned that research confirmed that. He got the "morals and ethics" right. That moral and ethical high-ground led him to pervert the science and he got caught at it. I repeat ... ITS ABOUT THE SCIENCE!

OK. Pauling was wrong and Watson and Crick were right. So? At the time there was no general knowledge about DNA. It was considered a curious molecule found in the cell nucleus that wasn't a protein that's constantly being created and consumed. It just seemed to "be there" with no clear purpose. There was certainly nothing resembling a consensus or even an informed opinion of its structure.

The consensus that the continents don't move, disease was caused by bad blood, cleanliness wasn't important in surgery, luminiferous aether, the earth is flat, the sun goes around the earth, etc., etc. were all wrong. Why should we automatically trust consensus?

Consensus

A few apt quotes ... “There is no such thing as consensus science. If it's consensus, it isn't science. If it's science, it isn't consensus. Period.” Michael Crichton “Science is not democratic: even if the majority of the scientific establishment subscribes to a particular view, this does not automatically make it right.” Martin Livermore, Cambridge, UK “To shut down debate is unscientific. Science progresses by observation and deduction, by setting up hypotheses and testing them. Allowing one view to be pushed forward with no dissent sets a precedent that will stifle innovative thinking. Whatever Al Gore may believe, there is an even more inconvenient truth: he could be wrong.” Martin Livermore "So, we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have." Professor Stephen Schneider, global warming guru at Stanford University Regards Bonzo

Bonzo, if you do not believe

Bonzo, if you do not believe that consensus can be achieved in science, then you must believe that there is no consensus on the existence of the force of gravity.

So, do you think we should reopen the case of the existence of gravity? Do you think we should allow those with different views to speak on this matter? (Maybe we should, then we would be able to identify the crackpots.)

Do you think we should discuss the attribution of the force of gravity? Who knows? Some people may disagree that it originates from the core. Some "innovative thinkers" may believe it is pressure exerted remotely by aliens who live on another planet.

Gravity ...

Unfortunately, Steve ol' buddy, gravity is a far from settled issue.

Scientists are now attempting to investigate a phenomenom called quantum gravity, negative gravity (i.e. dark energy) and gravitational effects associated with the mysterious dark matter.

Some guy, name of A. Einstein, proposed a theory that gravity is not a force at all. It is a curvature in space-time. That theory, called General Relativity, was in defiance of the "consensus" at the time.

Just as were the germ theory (Pasteur), antiseptics (Lister), evolution (Darwin), plate tectonics (Wegner), Smallpox (Jenner), neutron stars (Chandrasekhar).

Consensus doesn't have a very good track record. Even more to the point, nowhere in the scientific method, is there room for, or value placed on, achieving consensus. Claiming "consensus" is too often an attempt to cut off debate or refuse to examine evidence by pretending that all the answers are already known.

Not only is that unfounded for something like gravity, it is just plain ludicrous for something like climate science where the "consensus" is that we don't understand most of the mechanisms that govern it.

Crichton as a science source?

Bonzo, in case you found yourself in the wrong half of the library when you picked up Crichton's book it is found in the FICTION half of the library not the science section.

And it is complete nonsense to say that there is no consensus in science. How do you think things get into textbooks? They become accepted as representing the true state of the matter. Everything you read in textbooks, as opposed to the science literature, is consensus based.

There are many areas of science where no consensus has been reached and spirited debate occurs. However, the arguments put forward in these debates is science based not some irrational scribblings in a science fiction book.

Do you and other AGW deniers not see how silly you appear when all you have for support is a work of fiction?

Chrichton

Michael Chrichton appears to be quite a cluey and clever fellow as the following attests. Are your qualifications anywhere near as good? Michael Crichton is a writer and filmmaker, best known as the author of Jurassic Park and the creator of ER. His most recent novel, Next, about genetics and law, was published in December 2006. Crichton graduated summa cum laude from Harvard College, received his MD from Harvard Medical School, and was a postdoctoral fellow at the Salk Institute for Biological Studies, researching public policy with Jacob Bronowski. He has taught courses in anthropology at Cambridge University and writing at MIT. Crichton's 2004 bestseller, State of Fear, acknowledged the world was growing warmer, but challenged extreme anthropogenic warming scenarios. He predicted future warming at 0.8 degrees C. (His conclusions have been widely misstated.) Crichton's interest in computer modeling goes back forty years. His multiple-discriminant analysis of Egyptian crania, carried out on an IBM 7090 computer at Harvard, was published in the Papers of the Peabody Museum in 1966. His technical publications include a study of host factors in pituitary chromophobe adenoma, in Metabolism, and an essay on medical obfuscation in the New England Journal of Medicine. Repeat consensus is NOT science. Science does not run by ballot. The acid test for a hypothesis is whether or not it describes reality, not whether the majority of scientists or whoever vote for it. The very fact that a consensus is touted to verify anthropogenic global warming indicates that the hypothesis is not verified and has many uncertainties associated with it. Nobody, for example, says that there is a consensus that the sun will rise tomorrow. The sun will still rise even if 100% of scientists say it won't. Consensus has no place in science! Regards Bonzo “There is no such thing as consensus science. If it's consensus, it isn't science. If it's science, it isn't consensus. Period.” Michael Crichton “Science is not democratic: even if the majority of the scientific establishment subscribes to a particular view, this does not automatically make it right.” Martin Livermore, Cambridge, UK

I'm no climate expert.

I'm no climate expert. However, I'd wager that I have more qualifications in climate science that Crichton (having done an undergraduate honours thesis on an aspect of climatology and am planning to do a masters thesis on an aspect of Arctic climatology this fall).

I don't doubt that Crichton has high scientific credentials. (I knew he is an MD and has some extensive biological training. You didn't have to repeat this for me.) However, being an MD or having a Ph.D. in biology does not qualify one to consider themself as an expert in climate science. His numerous projects in anthropology do not qualify him to consider himself a climate expert. It's like a paleontologist considering themself to be an expert in nuclear physics. Complete rubbish!

Bonzo, why do you rely so often on Crichton instead of qualified climate scientists (i.e. climate experts) for your information on climatology? Is it that it would contradict your unfounded view that the planet is not warming or that it is not largely the result of greenhouse gas-emitting human activities? Are you trying to fit the square block into the round hole but it won't go in?

Global Warming

I think you guys will find this interesting, the link is http://solarscience.msfc.nasa.gov/SunspotCycle.shtml The Maunder Minimum Early records of sunspots indicate that the Sun went through a period of inactivity in the late 17th century. Very few sunspots were seen on the Sun from about 1645 to 1715 (38 kb JPEG image). Although the observations were not as extensive as in later years, the Sun was in fact well observed during this time and this lack of sunspots is well documented. This period of solar inactivity also corresponds to a climatic period called the "Little Ice Age" when rivers that are normally ice-free froze and snow fields remained year-round at lower altitudes. There is evidence that the Sun has had similar periods of inactivity in the more distant past. The connection between solar activity and terrestrial climate is an area of on-going research. Regards Bonzo "So, we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have." Professor Stephen Schneider, global warming guru at Stanford University

Global warming

Quote ... “Once a particular notion becomes conventional wisdom, evidence and stories confirming that conventional wisdom are easily accepted, and published - and reported in the media. Those that contradict the prevailing views have a much harder time getting a hearing.” Ronald Bailey, Reason Magazine You guys, aside from plain denial, have not properly addressed my basic questions ... 1. Why did the global mean temperature not respond to rising anthropogenic CO2 levels (which would have begun to rise about 1750) until about 1910? The global mean temperature was actually on a slight downtrend until 1910. 2. Why did the planet experience cooling from 1940 until about 1980 despite soaring CO2 levels? 3. The global temperature graph is nothing like a steadily increasing value. This alone should alert us to the possibility that there is NO CAUSAL RELATIONSHIP. I believe that the recent global warming (less than one degree Celsius since 1860!) has plateaued from 1998 onward. This is consistent with a peak in solar activity in July 2001 as indicated by a peak in sunspot activity. The sun's activity level is now waning, so we should start to see a global cooling trend from now on. More apt quotes follow ... "Unless we announce disasters, no one will listen" Sir John Houghton, first chairman of IPCC “The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary. “ H. L Mencken “The urge to save humanity is almost always only a false face for the urge to rule it.” H. L. Mencken

You didn't read the link I

You didn't read the link I gave you above. Go read it.

"At the moment it is just

"At the moment it is just the subject of two papers by Nir Shaviv and Jan Vizier demonstrating a link between climate and cosmic rays over long geological time periods."

If this is true, then it is as you said: "over long geological time periods," i.e. millennia-scale, not short periods like a century or so, which is what we are really concerned about. If this is true, then Shaviv's and Vizier's research is irrelevant.

Irrelevant ...

Your probably right. The recent time frame doesn't seem to compute because there has been little change in cosmic ray levels over the last 50 years or so (i.e. the time frame over which they have been measured.) As the saying goes "more research is needed."

Or to quote Dr. Einstein

If we knew what we were doing, it wouldn't be called research, would it?

'The recent time frame

'The recent time frame doesn't seem to compute because there has been little change in cosmic ray levels over the last 50 years or so (i.e. the time frame over which they have been measured.) As the saying goes "more research is needed."'

If "there has been little change in cosmic ray levels over the last 50 years or so", then it follows that cosmic rays have little or no role in the current warming and can be struck off the list of possible causes. Therefore, more research into cosmic rays and their impact on the current warming period is not needed.

That is not to say that more research into cosmic rays is not needed at all. The need to increase scientific knowledge implies that research must be done on as many issues as possible. However, in the realm of climate change, research into cosmic rays is one of the last things that needs to be done.

More research ...

Here's where there is still an unknown and a potential climate impact.

The referenced paper went into more detail than I did. It determined that these climate effects were predominately caused by relatively low energy cosmic rays that cause the formation of cloud condensation nucleii. Low energy cosmic rays are partially blocked by the solar wind and do not penetrate the atmosphere.

Higher energy rays do not cause the same kind of condensation nucleii and are relatively unaffected by the solar wind (i.e. they get through the atmosphere regardless of what the sun is doing.)

The solar observatory at the University of Colorado measures total cosmic ray flux but does not discriminate the distribution of cosmic ray energies.

The "further research" is therefore directed toward determining if the historical record supports the notion that low energy cosmic rays have varied with climate. There is also an experiment being conducted at CERN to verify or refute the connection between cosmic rays and cloud formation.

Sorry about all the techie stuff. Others have reprimanded me because "this is not a science site." ... oh well ...

Bonzo

Bonzo, the earth is a very complicated ecosystem. Here's your answers.

... Settled ... Part 3

I think we are more or less on the same page on some of the issues ... in different books on others.

Risk Assessment That one's really tricky. To properly assess risk you need to have some confidence that you can anticipate the consequences of taking (or not taking) some action. That seems to be the core of the disagreement. The AGW proponents view CO2 emission reduction programs as absolutely mandatory regardless of whatever downside they may entail.

While I don't disagree with the notion of reducing emissions (CO2 or anything else), I have more than a few doubts about what effect that will have on climate. Everything I've seen suggests that the answer is "minimal to undetectable". So even if we accept that the need to take action has been demonstrated ... are quixotic but very expensive programs that won't do anything about the problem really the answer?

The Money Trail Here we are in different books because you can't have it both ways. If, as portrayed on this site, the skeptics are really a rag-tag bunch of contrarians consisting of retired academics who do no research then they are clearly not looking for research funds. Or if they are, who would give them any?

I have little interest in accusing either supporters or opponents of AGW of dishonesty or crass commercial motives. I believe that both groups are primarily honest scientists attempting to determine the truth as best they can. Granted, there are some who have gone over to the dark side and actively promote the politicization of science but they tend to be fairly obvious and their proclaimations are to be taken with a very large grain of salt.

BCH -- you've got it

Oh darn, you let it slip away. Let's back up to: "if ... the skeptics are really ... retired academics who do no research then they are clearly not looking for research funds." That's exactly the problem. They are not looking for research funds. They are looking for PR funds. A lot of them aren't even scientists (look at the list of the sixty for a few examples).

Unlike some of the other 'consensus supporters' (e.g, VJ, below), I don't think that what the DSF does is entirely different from what the MANY ExxonMobil-supported groups do (although I still side with DSF as a matter of values). But that's not the point. The point is that the real researchers are not against the consensus. Okay, Dick Lindzen is a real researcher, but he's the exception that proves the rule. And even he has done no work that actually discredits the consensus view.

Recently one of the National Post's deniers (from a series they did on dissenting scientists) joined a conversation on desmog -- Richard Tol's position was that the attribution of recent warming to anthropogenic GHG emissions in the recent IPCC SPM (>90% likelihood) was understated. He thought >99% would be more appropriate (see at bottom, Saturday Feb 10 on this thread http://www.desmogblog.com/national-post-misrepresenting-climate-change-denial). I don't know what Richard Tol's motivations are and, like you, I don't care to spend much effort on it. But it doesn't take a clairvoyant to understand what the National Post was trying to do. Hint: they weren't trying to scare up funds for scientific research.

Got it ... but lost it

Good comments Steve.

I frankly don't have much appetite for this sort of trolling into people's financing or motivations. I do try to distinguish between the Op-Ed opinionizing and the technical papers that are published by working scientists. For that reason, although I do read them, I tend to put Steven Milloy and Al Gore (for example) in much the same position in the debate. Both of them quote science that supports their preconceived views and conveniently ignore what does not support those views.

That said, it would be naive to assume that all published science is good science. There have certainly been examples of publications where the standard of scientific practice was later shown to be faulty and even downright fraudulent. To really gain some understanding of the state of affairs it is necessary to make a conscious effort to dispense with your natural prejudices (and we all have them) and make a serious attempt to separate science from spin.

You state that "... real researchers are not against the consensus ..." but you do allow an exception for Linzden.

Now we are back to the definition thing. What consensus would that be? The globe is warming? You're correct ... they all agree. CO2 is increasing? Agree again. CO2 is contributing to warming? No argument. CO2 is the primary or dominant contributor to warming? Oops ... just hit a roadblock. Most of the papers that I've seen acknowledge that CO2 is a contributor but they are very careful to include the disclaimer that so are aerosols, clouds, solar, land use changes and a host of other factors. They are also careful to state that, although CO2 contributes, the extent of that contribution and it's future state are subject to a lot of uncertainty.

Even more to the point however is that science does not function like politics (or at least, it isn't supposed to.) Consensus is not the measure of whether or not a piece of scientific research is an accurate description of how nature works. That is determined by other scientists ("skeptics" if you will) examining the science and being able to replicate the results. MBH98's hockey stick was certainly in agreement with the consensus but ultimately it was bad science because it failed the reproducability test.

WHY aren't we interested in

WHY aren't we interested in deniers' motivation? This is a critical mistake. The deniers are dangerous and need to be stopped. Discovering their motivation serves two purposes: 1) It helps create an argument to refute their claims 2) It can help put doubt in the mind of those who may listen to them For example, assuming that most deniers are afraid that combatting GW will result in higher taxes, you can refute that concern by explaining how GW can be combatted at a reasonable cost. Also, if high taxes are the pure reason someone denies that GW exists, you can point out to the undecided audience that the motivation is pure selfish greed. This would make all following claims less credible.

Clarifying "Consensus"

As I see it, the distinction here is one of "applied" vs "pure" science. Fact is, in highlighting this (anthropogenic) problem, which probably needs an anthropogenic response, climate science is moving from the realm of pure science to applied. It's no longer an ivory-tower pursuit: findings have consequences.

And when it's a question of real-world action, then a different standard applies. ALL the applied sciences operate solely on the principle of consensus. How could a doctor function without accepting a body of accumulated wisdom from biologists and medical researchers--in other words, (mostly) trusting the AMA and others to come to a consensus about the most likely causes of disease, or the best treatments, etc. Ditto civil engineering, architecture... And yet all of these fields, especially medicine, continue to be updated, improved, and even proven wrong at times.

If your doctors tells you "I think I'll wait until ALL the science is in before I reach a diagnosis", fire your doctor.

Doctors

ALL the applied sciences operate solely on the principle of consensus.

I think that you have it backwards. Consensus exists because the principles and techniques have been demonstrated to work as advertised in the real world. It is that demonstration of practical functionality that drives applied science ... not the fact that everyone agrees with it.

That is quite different than a consensus which says that we have a low level of scientific understanding for two-thirds of the factors that may influence climate but we think this is what's going on. Viewed realistically, the consensus is more an agreement on how little we know rather than how much.

You're correct in that the medical profession doesn't wait for all the science to be in but they definitely do all the testing that they can before they attempt treatment (despite what you see on "House".) Their rule is "First ... do no harm."

A young relative of mine (2 months old) was recently diagnosed with a mysterious heart condition. Possible solutions included open heart surgery and a heart transplant. In the end they gave her some medication to control tachicardia and waited. She is now fine and exhibits no symptoms of the problem.

I mention all this because we have the same problem with global warming. The "cure" (i.e. draconian programs for fossil fuel reduction) may be worse than the disease and, from all indications, won't cure it. Realistically, we can cut out dependence on fossil fuels only by developing energy sources to replace them. Ours is an energy-intensive society and the notion that we can just turn the clock back to some mythical bucolic existence when fossil fuels were a minor part of our lives is just foolish. I also believe that such programs will fail because people who want to save the planet now will change their tune when they are freezing in the dark and paying through the nose to do it.

BCH, let's be consistent

BCH, I rather appreciate your efforts here, but I want to register a complaint. You're smart enough to recognize that the consensus science position is not that "all climate change occurs due to CO2." Why don't you also recognize that reducing CO2 emissions can occur by degree? I'm not sure, but I might agree that there would be a lot of negative socio-economic effects of reducing emissions VERY QUICKLY. But it's not like the people who think we should reduce emissions all want draconian regulations. I shouldn't speak for others, but we want SOME regulations. We want to slow down the titanic before it hits the iceberg. If the ship started tearing apart first, I'm quite sure the regulations could be relaxed a bit. In your words, "people who want to save the planet now will change their tune when they are freezing in the dark." They'll change their minds long before that. Thinking about where your argument is coming from, I don't see how you can consider that a bad thing?

Regulations ...

Steve ... I agree. We definitely do need to have plans in place to mitigate environmental impacts (including but not restricted to CO2).

What I was reacting to was proposals like Study puts cost of meeting Kyoto climate-change targets at $100 billion. That's only a newspaper article and not the actual study but it is illustrative of the kind of thinking that's out there. It even got the math wrong. It's not $20/week/family ... you would need $43/week/family or about $2300/year to collect this much money. Even worse, since it is a CO2-specific proposal, it will probably have no detectable effect on climate and will divert bales of money away from a lot of other areas where that much money would really make a difference.

As I've said in other posts here, if we are really serious about this we need multi-decadal plans to come up with alternatives to fossil fuels. Just attempting to mitigate the effects of using them but still continuing to do so will get us nowhere.

BCH, for your money trail,

BCH, for your money trail, go to the front page of DeSmogBlog and look at the section called "Who are the Sixty?" For instance, today's entry includes this quote:

"...Along with the report was a letter of endorsement signed by numerous representatives of various organizations, including 6 that have recieved a total of $2.32 million in donations from ExxonMobil over the last three years..."

You see, who needs research funding when ExxonMobil will pay you to go around giving talks and spouting nonsense? You want a money trail; check out all of the entries in "Who are the Sixty?"

About the climate cover-up

About the climate cover-up

Democracy is utterly dependant upon an electorate that is accurately informed. In promoting climate change denial (and often denying their responsibility for doing so) industry has done more than endanger the environment. It has undermined democracy.

There is a vast difference between putting forth a point of view, honestly held, and intentionally sowing the seeds of confusion. Free speech does not include the right to deceive. Deception is not a point of view. And the right to disagree does not include a right to intentionally subvert the public awareness.

Although all public relations professionals are bound by a duty to not knowingly mislead the public, some have executed comprehensive campaigns of misinformation on behalf of industry clients on issues ranging from tobacco and asbestos to seat belts.

Lately, these fringe players have turned their efforts to creating confusion about climate change. This PR campaign could not be accomplished without the compliance of media as well as the assent and participation of leaders in government and business.
