Thucydides said:
PHD's are experts in their own fields, so I would listen to a space scientist talking about space, not climate.
This little piece by Thuc. is probably the only intelligent statement in this thread in the last few months.
It's unfortunate that most here, including Thuc. himself, don't take it to heart and draw the proper derivative conclusion from it, which is then that
PhD's in climatology are the ones we should listen to on matters of climate science.
Those of us that have been convinced of the scientific reality of Climate Change (meaning here that there is a major and rapid shift about to occur in the planet's climate, that is almost certainly caused by recent human activity in the last hundred years, and will have profound effects on human society, perhaps even existence) DO have climatologists (PhD's and above in climatology) on our side. It is called the IPCC report on Climate Change. The single largest ever peer reviewed scientific consensus.
No one denies the existence of that report, nor that its conclusion is that which I expressed above in parenthesis. So it is up to those not convinced in these pages to provide
scientific evidence from
climatologists to the contrary as reported in
proper scientific peer reviewed papers. Not from pseudo-scientists in other fields, not from social scientists and other forms of lobbyists/Government issues think-thank, nor bloggers or other op-ed sources.
On that basis, let's review Thuc's latest offering:
Thucydides said:
Kilo. while you can play the same moving goal posts game as other AGW alarmists, the historical record is clear and unequivocal. Unless you can demonstrate that the Vikings were busy driving to their conquests in SUV's (and idling outside of the cities they sacked) there is no explanation involving human agency to explain the archeological remains of croft farms in Greenland or the records of Scottish vintners in that period. Or are you a history denier?
I suppose you also expect us to believe that the Little Ice Age is also some sort of hoax as well?
Real science starts with observations, and observations like Vikings were doing a type of farming in Greenland that is not possible today fly directly in the face of the climate change alarmists. The other predicted effects of warmer temperatures, like agricultural distress or violent storms are also not supported in the historical record (indeed the population during the European Warm Period was growing due to better harvests, and there are historical records from parishes to prove this as well), but we are expected to believe that a similar amount of warming that the Vikings experienced is going to create a global disaster for us.
Yes, Thuc. science
starts with observations, but it doesn't stop there and then go right away into a simplistic pseudo-social-sciences battle of false logic such as : "it rained yesterday, so we are not in a drought" or "it was cold two winters ago, so the planet is not warming", or "there were only ten hurricanes last year as opposed to an average of twelve, so the predicted increase in hurricane frequencies is wrong". What science does is collect a large number of data, collate, plot and analyze them then identify trends, identify potential causes for the observed trends, postulate relationship between the various causes and the effects observed, from that develop theories, verify if the theories can be validated or invalidated by their application to past data, and if so if they properly predict future situations.
For instance, we now know, through science, that until about 10,000 years ago, monsoon rains fell in what is now the Sahara desert, making it green and lush for most of the year and causing a wide variety of human and other animal life to flourish there. That, and your Little Ice Age, and the European Warm period you described have been scientifically proven to be the result of variations in the Earth's orbit around the sun, and in its spin axle and in sun activity changes. However, those variations and there effects are known facts that were incorporated and are taken into consideration by the climatologists models that led them to conclude in the existence of Global Warming.
So, your reference to them and their historical existence is irrelevant to the science, which has already taken note of it and incorporated it in its conclusion.
Let's now turn to your alleged supporting evidence,
using here the tools of proper peer-reviewed social science research:
Thucydides said:
And of course NASA also has this observation about climate change:
http://news.yahoo.com/nasa-data-blow-gaping-hold-global-warming-alarmism-192334971.html
Can you remind us which oil companies pay NASA scientists again?
First of all, it is simply a lie that NASA "has this observation". You refer to an article, in Forbes.com, which is an Op-Ed piece by one James M. Taylor. Forbes is not a NASA magazine, nor even a scientific publication; Mr. Taylor, who is not a scientist at all (as we will see a little further on), has no connection to NASA whatsoever, and nowhere in the article is there any reference to an actual statement, official or not, of a NASA representative, to the effect stated in the title. Bluntly put, Mr. Taylor's opinion piece does not report NASA's position in any way, form or shape.
Second, as indicated, I call Mr. Taylor's piece an "opinion". Why? Because he himself presents it as such ( https://www.heartland.org/james-m-taylor-jd ).
But moving on to the third point, If as you stated above Thuc, you listen to PhD's in a given field as the proper expert (my starting point in this post), then what field is Mr. Taylor from? See the link above to his employment with the Heartland institute: He is a "Jd" - meaning he has completed his law degree - he is a lawyer but doesn't present himself as such, probably because he is not a member of any Bar and has never practiced. HAs he other qualifications? Yes, he has a bachelor's degree. In what, we don't know. He states that "received his bachelor's degree from Dartmouth College where he studied atmospheric science and majored in government. So the major is in government studies. The statement that he "studied atmospheric science" however is unqualified and can stand for the fact that he took a basic low level course in that subject as one of his elective. None of this makes him an expert in anything.
Then we have to look at where he comes to us from: The Heartland institute. Who are these people? Well, THEY claim to be " a 31-year-old national nonprofit research organization
dedicated to finding and promoting ideas that empower people." Their mission statement is: "Mission: Its mission is to discover, develop, and promote
free-market solutions to social and economic problems." (source: https://www.heartland.org/about)
See any reference there to peer reviewed climatology science? I don't. And a quick review of their "expert" panel of collaborators indicate an organization that is 99% made up of business administration professors, law professors and other jurists, government affairs professors and economists. This is NOT a scientific (in the sense of "hard" sciences) organization at all.
Turning now to Mr. Taylor's opinion, I find it to be a sophisticated piece of falsity by unwarranted association. First of all, the constant reference to data from NASA and NOAC is presented to make one believe that it is contradicting in itself the whole Global Warming science and that the scientist who put out the paper basically rejected the validity of the IPCC models and "blew them out", which is completely false: They never reach that conclusion in their paper (I have attached the paper for reference for any one who cares, as I did to read it and try to understand it). Then Mr. Taylor refer to the "press release" of the University to support HIS own view of what he wants them to mean, not the scientist's view.
What are the scientist's real conclusions then? The current models generally used by scientists part of the IPCC review hypothesized that the dissipation of heat in the upper atmosphere from any given warming event would not begin until the maximum of the event is reached and would cease when the minima of the warming event is reached. The article in this case compares various such models with the observed data from a system located ON a NASA satellite during the last ten years and concludes that there is a time lag between the observed data and the models' predictions of heat dissipation, such that dissipation actually begin to occur before the maxima and continues for some times after the minima is reached. As a result, the scientists conclude that it
might be that there is a greater amount of dissipation from warming event than currently predicted, so
it might be that the upper atmosphere of the planet
may not warm up as fast as the models predict.
At no point do the scientist: (1) reject the current overall models; (2) conclude in any way that their research contradicts Global Warming; or that (3) the current models are "alarmists" and there is in fact no danger/Global Warming.
They do conclude, however, that after 20 years of research and modelling, it remains difficult to distinguish from one another the contributions of the various factors influencing climate change and that their research does not permit better distinguishing, which remains elusive.
What those scientists have down is taken data as observed and shown that, for one of the aspects of the modelling, it currently does not match
in timing and
may not match in total amount either. Now, other scientists will review this research and either confirm it or prove it incorrect and will then work to develop better potential explanations, refine the model accordingly and adjust the results predicted as a consequence.
This is all in the future, probably by many decades, and may ultimately mean no change, little change or big change in the ultimate conclusion. Right now, no one can know for sure, other than the fact that the rest of the modelling is unchanged and the overall observed results continue to pan according to the current state of research. Anyone who expands this to mean that Global Warming has been debunked is an idiot with no understanding whatsoever of the scientific method.
