That was very interesting.  I think I sensed the gist of it, but quite a bit of it went right over my head with nary a look back  :oops: :lol:

Changing subjects abruptly, a couple of days ago I saw a seemingly serious piece about sun spots and their relation to temperatures here on earth.  I would have posted it here, but I was on the road at a computer which wasn't mine and didn't have the time at the moment.   

Anyway, I have been keeping an eye out for the sunspot hypothesis for a while now.  I have seen articles which stated that Mars's temperatures have increased proportionately to earth's temperatures, which suggests a non-terrestrial cause of earth's variations i.e. the sun.  The article the other day said that something very unusual had happened with the sun spots-- there were none for a certain amount of time and said that data seems to correlate this with prior cooling periods on the earth.   Of all the people I know you are amongst the few likely to be aware of or able to track this down.    If your readings bring it to your attention, would you be so kind as to bring it here and offer your comments?

TIA,
Marc

Sun Makes History: First Spotless Month in a Century

Drop in solar activity has potential effect for climate on earth.

The sun has reached a milestone not seen for nearly 100 years: an entire month has passed without a single visible sunspot being noted.

The event is significant as many climatologists now believe solar magnetic activity – which determines the number of sunspots -- is an influencing factor for climate on earth.

According to data from Mount Wilson Observatory, UCLA, more than an entire month has passed without a spot. The last time such an event occurred was June of 1913. Sunspot data has been collected since 1749.

When the sun is active, it's not uncommon to see sunspot numbers of 100 or more in a single month.  Every 11 years, activity slows, and numbers briefly drop to near-zero.   Normally sunspots return very quickly, as a new cycle begins.

But this year -- which corresponds to the start of Solar Cycle 24 -- has been extraordinarily long and quiet, with the first seven months averaging a sunspot number of only 3. August followed with none at all. The astonishing rapid drop of the past year has defied predictions, and caught nearly all astronomers by surprise.

In 2005, a pair of astronomers from the National Solar Observatory (NSO) in Tucson attempted to publish a paper in the journal Science. The pair looked at minute spectroscopic and magnetic changes in the sun. By extrapolating forward, they reached the startling result that, within 10 years, sunspots would vanish entirely. At the time, the sun was very active. Most of their peers laughed at what they considered an unsubstantiated conclusion.

The journal ultimately rejected the paper as being too controversial.

The paper's lead author, William Livingston, tells DailyTech that, while the refusal may have been justified at the time, recent data fits his theory well. He says he will be "secretly pleased" if his predictions come to pass.

But will the rest of us? In the past 1000 years, three previous such events -- the Dalton, Maunder, and Spörer Minimums, have all led to rapid cooling. One was large enough to be called a "mini ice age". For a society dependent on agriculture, cold is more damaging than heat. The growing season shortens, yields drop, and the occurrence of crop-destroying frosts increases.

Meteorologist Anthony Watts, who runs a climate data auditing site, tells DailyTech the sunspot numbers are another indication the "sun's dynamo" is idling. According to Watts, the effect of sunspots on TSI (total solar irradiance) is negligible, but the reduction in the solar magnetosphere affects cloud formation here on Earth, which in turn modulates climate.

This theory was originally proposed by physicist Henrik Svensmark, who has published a number of scientific papers on the subject. Last year Svensmark's "SKY" experiment claimed to have proven that galactic cosmic rays -- which the sun's magnetic field partially shields the Earth from -- increase the formation of molecular clusters that promote cloud growth. Svensmark, who recently published a book on the theory, says the relationship is a larger factor in climate change than greenhouse gases.

Solar physicist Ilya Usoskin of the University of Oulu, Finland, tells DailyTech the correlation between cosmic rays and terrestrial cloud cover is more complex than "more rays equals more clouds". Usoskin, who notes the sun has been more active since 1940 than at any point in the past 11 centuries, says the effects are most important at certain latitudes and altitudes which control climate. He says the relationship needs more study before we can understand it fully.

Other researchers have proposed solar effects on other terrestrial processes besides cloud formation. The sunspot cycle has strong effects on irradiance in certain wavelengths such as the far ultraviolet, which affects ozone production. Natural production of isotopes such as C-14 is also tied to solar activity. The overall effects on climate are still poorly understood.

What is incontrovertible, though, is that ice ages have occurred before. And no scientist, even the most skeptical, is prepared to say it won't happen again.

Article Update, Sep 1 2008.  After this story was published, the NOAA reversed their previous decision on a tiny speck seen Aug 21, which gives their version of the August data a half-point.  Other observation centers such as Mount Wilson Observatory are still reporting a spotless month.  So depending on which center you believe, August was a record for either a full century, or only 50 years.

Guinness,  Thanks for the excellent post from Wm Briggs. I wasn't aware of his work. Just looking at the graph it is easy to see how any (crooked) statistician could measure temperature from a trough in the late 1800s or a peak in the early 1600s and (falsely) declare significant amounts of warming or cooling over an extended period.  They not only filter the data statistically, but they also tweak the actual temp data collected with secret algorithms that are written and changed by mortals with biases.

By my calculation, the sea level at the beach in Florida or southern California goes up and down more in a day than it does in a century.  I'm glad that scientists study it all and offer their judgments, but not on my dime.

The 'consensus' on climate change is a catastrophe in itself
By Christopher Brooker
Last Updated: 12:01am BST 31/08/2008

As the estimated cost of measures proposed by politicians to "combat global warming" soars ever higher – such as the International Energy Council's $45 trillion – "fighting climate change" has become the single most expensive item on the world's political agenda.

As Senators Obama and McCain vie with the leaders of the European Union to promise 50, 60, even 80 per cent cuts in "carbon emissions", it is clear that to realise even half their imaginary targets would necessitate a dramatic change in how we all live, and a drastic reduction in living standards.

All this makes it rather important to know just why our politicians have come to believe that global warming is the most serious challenge confronting mankind, and just how reliable is the evidence for the theory on which their policies are based.

By far the most influential player in putting climate change at the top of the global agenda has been the UN's Intergovernmental Panel on Climate Change (IPCC), set up in 1988, not least on the initiative of the Thatcher government. (This was why the first chairman of its scientific working group was Sir John Houghton, then the head of the UK's Meteorological Office.)

Through a succession of reports and international conferences, it was the IPCC which led to the 1997 Kyoto Protocol, soon to have an even more ambitious successor, to be agreed in Copenhagen next year.

The common view of the IPCC is that it consists of 2,500 of the world's leading scientists who, after carefully weighing all the evidence, have arrived at a "consensus" that world temperatures are rising disastrously, and that the only plausible cause has been rising levels of CO2 and other man-made greenhouse gases.

In fact, as has become ever more apparent over the past 20 years –not least thanks to the evidence of a succession of scientists who have participated in the IPCC itself – the reality of this curious body could scarcely be more different.

It is not so much a scientific as a political organisation. Its brief has never been to look dispassionately at all the evidence for man-made global warming: it has always taken this as an accepted fact.

Indeed only a comparatively small part of its reports are concerned with the science of climate change at all. The greater part must start by accepting the official line, and are concerned only with assessing the impact of warming and what should be done about it.

In reality the IPCC's agenda has always been tightly controlled by the small group of officials at its head. As one recent study has shown, of the 53 contributors to the key Chapter 9 of the latest report dealing with the basic science (most of them British and American, and 10 of them associated with the Hadley Centre, part of the UK Met Office), 37 belong to a closely related network of academics who are all active promoters of the official warming thesis.

It is on the projections of their computer models that all the IPCC's predictions of future warming are based.

The final step in the process is that, before each report is published, a "Summary for Policymakers" is drafted by those at the top of the IPCC, to which governments can make input.

It is this which makes headlines in the media, and which all too frequently eliminates the more carefully qualified findings of contributors to the report itself.

The idea that the IPCC represents any kind of genuine scientific "consensus" is a complete fiction. A

gain and again there have been examples of how evidence has been manipulated to promote the official line, the most glaring instance being the notorious "hockey stick".

Initially the advocates of global warming had one huge problem. Evidence from all over the world indicated that the earth was hotter 1,000 years ago than it is today.

This was so generally accepted that the first two IPCC reports included a graph, based on work by Sir John Houghton himself, showing that temperatures were higher in what is known as the Mediaeval Warming period than they were in the 1990s.

The trouble was that this blew a mighty hole in the thesis that warming was caused only by recent man-made CO2.

Then in 1999 an obscure young US physicist, Michael Mann, came up with a new graph like nothing seen before.

Instead of the familiar rises and falls in temperature over the past 1,000 years, the line ran virtually flat, only curving up dramatically at the end in a hockey-stick shape to show recent decades as easily the hottest on record.

This was just what the IPCC wanted, The Mediaeval Warming had simply been wiped from the record.

When its next report came along in 2001, Mann's graph was given top billing, appearing right at the top of page one of the Summary for Policymakers and five more times in the report proper.

But then two Canadian computer analysts, Steve McIntyre and Ross McKitrick, got to work on how Mann had arrived at his graph.

When, with great difficulty, they eventually persuaded Mann to hand over his data, it turned out he had built into his programme an algorithm which would produce a hockey stick shape whatever data were fed into it.

Even numbers from the phonebook would come out looking like a hockey stick.

By the time of its latest report, last year, the IPCC had an even greater problem. Far from continuing to rise in line with rising CO2, as its computer models predicted they should, global temperatures since the abnormally hot year of 1998 had flattened out at a lower level and were even falling – a trend confirmed by Nasa's satellite readings over the past 18 months.

So pronounced has this been that even scientists supporting the warmist thesis now concede that, due to changes in ocean currents, we can expect a decade or more of "cooling", before the "underlying warming trend" reappears.

The point is that none of this was predicted by the computer models on which the IPCC relies.

Among the ever-growing mountain of informed criticism of the IPCC's methods, a detailed study by an Australian analyst John McLean (to find it, Google "Prejudiced authors, prejudiced findings") shows just how incestuously linked are most of the core group of academics whose models underpin everything the IPCC wishes us to believe about global warming.

The significance of the past year is not just that the vaunted "consensus" on the forces driving our climate has been blown apart as never before, but that a new "counter-consensus" has been emerging among thousands of scientists across the world, given expression in last March's Manhattan Declaration by the so-called Non-Governmental Panel on Climate Change.

This wholly repudiates the IPCC process, showing how its computer models are hopelessly biased, based on unreliable data and programmed to ignore many of the genuine drivers of climate change, from variations in solar activity to those cyclical shifts in ocean currents.

As it was put by Roger Cohen, a senior US physicist formerly involved with the IPCC process, who long accepted its orthodoxy: "I was appalled at how flimsy the case is. I was also appalled at the behaviour of many of those who helped produce the IPCC reports and by many of those who promote it.

"In particular I am referring to the arrogance, the activities aimed at shutting down debate; the outright fabrications; the mindless defence of bogus science; and the politicisation of the IPCC process and the science process itself."

Yet it is at just this moment, when the IPCC's house of cards is crumbling, that the politicians of the Western world are using it to propose steps that can only damage our way of life beyond recognition.

It really is time for that "counter-consensus" to be taken seriously.
