NAS Findings on Al Gore's Facts: Late 20th Century Warming

[Skyhunter]

Ah we're getting in the name calling stage and seeing the fallacy density increasing remarkedly with several other type of red herrings, like the doubling CO2 thinghy. I wonder when Godwins law kicks in.

You are the one who said:

5. Carbon dioxide is the strongest greenhouse gas and is the primary driver for climate changes.

That’s most definitely false. It is not, and I have showed that many times in the Earth science threads. The effect is minor, not something to worry about.

Besides I was not name calling. I am a Leprechaun. :tongue:

How nice to quote Michael Mann on his blog in Dec 2004 and demonstrate that he taught you all, how to use the ad hominem:

But keep them coming please. Nice material for the courts of justice in due time. We will not forget it when it's time to clean out this mess.

That is not ad hominem, that is disclosure.

So where did you get that record from, from 1000AD to 2000AD? Or are you meaning the record of the 19th century where the skill of the corrollation r2 is not exceeding 0,00?

The observed temperature record is what is used to calibrate proxy evidence.

http://www.realclimate.org/index.php/archives/2006/11/strawmen-on-greenland/#more-374

Proxy records (ice cores, ocean sediments etc.) that are related to climate (in some imperfectly known way, but with non-climatic 'noise') go back further. But they need to be calibrated to the instrumental record in order to be used quantitatively. Given that proxy records don't always extend to the present (due to collection dates, collection method, the physics or biology of the specific proxy) and that it is important to retain some instrumental data for validation of any calibration, there are only ~60-100 years of record left for the calibration - making it very difficult to assess how well the low frequency component (a few decades or longer) is represented (and much of the recent attention to recent proxy reconstructions really relates to exactly this point, rather than technical arguments about data processing). Of course, proxy records can also be usefully combined in a qualitative ways that don't require calibration (such as Osborn and Briffa, 2006).

Please be so kind and show where it is proven that the temperature reconstruction after removal of the Bristlecone pines still produces hockeysticks. After all if the reconstruction is robust, the removal of one proxy should not lead to strong abbarations.

It has not been to my knowledge. If you remove the bristlecones, you have a warmer MWP.

Again I ask, why remove the proxy evidence that most closely matches the instrumental record?

The reproduction of the work of others is one of the cornerstones of science. So what is the problem? Obviously, when there is no science then there is a problem.

That should be the job of independant scientists, not industry representatives.

Finally about


Whilst it was observed by Graybill and Idso (Graybill, D.A., and S.B. Idso, (1993). Global Biogeochemical Cycles, 7, 81-95.) that the remarkable accelerated growth in the Sierra Nevada as of 1850 could not be attributed to local climate changes, hence it was attributed to anthropogenic CO2 fertilization. You will find the source quoted over and over again. Personally I'm thinking of increased air pollution due to the use of coal with SOx/NOx type of fertilizers. But that's all forgotten now. Everything is caused by global warming of course

So you are now attacking the source that you were just using to attack the hockey stick?

Talk about a red herring.

[Edit]
Actually this entire thread is a red herring. Even if MM05 is the gospel on the MWP, it has little bearing on what is happening today.

The observed temperature record is what is used to calibrate proxy evidence.

And any icea what it means when the r2=0.0 in that process?

That should be the job of independant scientists, not industry representatives.

What difference does it make if the math is debunked by ***fill in the same vicious villain here***. If you don't trust it, check the checker. And that is what both NAS North and Wegman did independently and both reported that those alleged industry representatives were right that the hockeystick was based on nothing.

Meanwhile, perhaps it's an idea to reflect a bit about what is happerning here. your continuous ad homs and red herrings might give the readers here some idea about your priorities. Science truth, or winning a fight at all costs.

Andre your accusations of ad hominem attacks are ironic since you are the one whose argumentative style is to attack the opposition at the personal level (e.g. "Al Gore's own Facts?"). AFAICS you are a conspiracy theorist who believe nobody can disagree with you unless they are paid off. Your determination to argue about the hockey stick two years after everybody else declared a wash and moved on shows where you are coming from.

Check again, the opening post was not an attack against the person. I was neither discussing his past behavior nor question his motives to do what he does. Again, I merely showed that within a few sentences from affirming the importance of facts, he offended against it already. That's not an ad hominem. Why is that so difficult?

Your determination to argue about the hockey stick two years after everybody else declared a wash and moved on shows where you are coming from.

It's not that easy. The hockey stick has been declared a fraud by insiders. I linked to that. Both the NAS report and the Wegman report were filed this year confirmed that the math was plain wrong. But the whole world fell for the no-brainer, when the hockeystick showed up prominently in the http://www.ipcc.ch/pub/spm22-01.pdf . A fraud? So how about those who want to cover that up as soon as possible? We are not moving on, we will correct what went wrong, at least for historical purposes when in 2030 our children and grandchildren are analyzing what put them in the renewable energy misery and the economic energy bankrupcy while suffering from the next little ice age aka Landscheidt solar minimum.

Found all the appropriate elements here in this expose:

http://ff.org/centers/csspp/library/co2weekly/20061201_02/20061201_03.html

Particulary interesting:

Richard Lindzen opines that three claims which have widespread scientific support - global mean temperature has increased by about one degree since the end of the 19 th century; levels of CO2 in the atmosphere have increased by about 30% during the same period; and CO2 should contribute to future warming - neither constitute support for alarm nor establish man's responsibility for the warming that has already occurred.

This responsibility is also thrown back into question by some researchers in Canada, especially by Ian Clark, a Professor of Hydrogeology and Paleoclimatology at the University of Ottawa. Indeed, these researchers believe that global warming is mainly the consequence of a more intense solar activity. They have shown, in particular, that global warming and cooling cycles match with the solar cycle with a small lag.(1)

According to Richard Lindzen, alarmists are trumpeting "model results that we know must be wrong." Still worse, they are trumpeting "catastrophes that could not happen even if the models were right as justifying costly policies to try to prevent global warming."

As Claude Allègre who observes that "the ecology of helpless protest has become a very profitable business for some people", Lindzen specifies that the success of climate alarmism can be gauged in terms of the increased federal spending in the US on climate research: this spending rocketed from a few hundred million of dollars before 1990 to 1.7 billion dollars today.

It is not easy to stand up against that which locks contemporary climate science in alarmism. One must be a former minister and one of the most honoured French scientists - Mr. Allègre is a Crafoord laureate, was awarded the Wollaston Medal, and is also recipient of the Gold Medal of the CNRS - in order to dare fly in the face of taboos and not give into fear and intimidation.

Other persons have also had this courage. Thus, in the early 90's, the American journalist Ted Koppel (a 42-year veteran of ABC News)(2) deemed publicly inappropriate a request made by Al Gore, then Vice President of the US, to get involved in a witch-hunt to discredit anti-alarmist scientists.

We live in very interesting times.

Just to make sure about the science of climate:


Khilyuk, L.F., and G. V. Chilingar. 2006. On global forces of nature driving the Earth’s climate. Are humans involved? Environmental Geology, 50, 899–910.

Abstract
The authors identify and describe the following global forces of nature driving the Earth’s climate: (1) solar radiation as a dominant external energy supplier to the Earth, (2) outgassing as a major supplier of gases to the World Ocean and the atmosphere, and, possibly, (3) microbial activities generating and consuming atmospheric gases at the interface of lithosphere and atmosphere. The writers provide quantitative estimates of the scope and extent of their corresponding effects on the Earth’s climate. Quantitative comparison of the scope and extent of the forces of nature and anthropogenic influences on the Earth’s climate is especially important at the time of broad-scale public debates on current global warming. The writers show that the human-induced climatic changes are negligible.

Some comments here.

 

[ND3G]

Andre, while I applaud your quest for hard proof one way or the other I for one do not need to have every single detail hammered out before I find myself compelled to act.

You can happily argue the merits of one theory over that theory till the cows come home but those of us willing to act will simply work around you.

Is pollution causing global warming? Probably

Would it matter even if it wasn't? Not in the slightest

No matter how you slice it, pollution is bad for the environment. So any attempt to reduce pollution can only be seen as a positive.

Do we really need a domesday scenario before people are willing to act?

Quote: Humans may be responsible for less than 0.01°C (of approximately 0.56°C (1°F) total average atmospheric heating during the last century)”.

Ok, so let's do everything in our power to stop that 0.01°C increase we are causing. Even if things are not as bad as some people may say, they are still anything but good...

 

[Andre]

I for one do not need to have every single detail hammered out before I find myself compelled to act.

From your reaction ND3G, I'm afraid that I failed to make my point. I'll give it another try.

What is "Action"? As long as an observed situation is in concurrence with the desired state, nothing needs to happen. However when things go wrong and need to be corrected, a natural cognitive feedback loop can be distinghued, which can be described in four steps: Observation, Orientation, Decision and Action. This "OODA loop" has been described by late John Boyd, also a colleague fighter pilot. Nowadays, people devote PhD theses to these ideas, like http://www.d-n-i.net/osinga/science_and_strategy.htm . Now the point is: for winning a conflict from an enemy one should optimize ones own OODA loop while attempting to disrupt the OODA loop of the adversary. History has proven over and over that this far outweights numbers and force potential.

But this is not exclusively fighter pilot business in conflict situations, this feedback loop applies to virtually everything what we do: We don't like it, so we do something. We react with an OODA loop (even this post is the result of such a loop). And the point is we need to do that loop as quickly and as accurately as possible. When you think it all over, it's like alsmost resembling science.

Now here the climate kicks in. We observe changing climates and a lot of proxy readings, we analyse that CO2 has something to do with it. We decide that we should curb emissions and we act by going to Kyoto. But where is the accuracy? The culprit is the analysis part.

The first analysis pertained to Arrhenius and the greenhouse gas effect theory but quantitatively he made an error of a factor 4. This was recognised later but anyway. We had also observed modern temperatures going up momentarily in the 1980-1990 time frame and CO2 going up. Then the ice cores came with the CO2 and isotope spikes (alleged temperature spikes) of the Pleistocene, which was analysed as flickering climates CO2 causing temperature changes. "Ten degrees within a decade!" . So we analyse that we are in big trouble and we need to decide to do something quickly or else fry. But how to get this decision endorsed in the international policy arena with agenda's and conflicts of interest? One really needs to carry a very big stick to get the action going? Would that be the reason why people started to spindoctor observations like the hockeystick or work out demagoguery tactics like "the debate is over"? Apparantly all to enforce the decision and projected action?

However, then gradually more and more observations of the ice age came in, especially CO2 lagging the isotopes. Also many reports of greater climate variability in other era that were not in correlation with CO2 and it was analysed that climate was much more complicated than that. Things like nett positive water vapour feedback were invented but could never be shown to exist so, despite heroinic attemps of Brian Soden et al. From a pure scientific point of view, there is very little left of the original analysis of a strong relationship between CO2 and temperature (that is if you want to look and not to ignore). Only the models still seem to believe in it.

And here is where things are screwed up, the rigidized OODA loop, not reacting anymore on changes in the observations and analysis and that's where I am fighting against, for the record of course, since it's chanceless anyway.

But if your OODA loop is wrong you're bound to screw up the reality which you wanted to correct to the desired situation and my personal OODA loop says that we should try and prevent that.
