Global Warming? Global Cooling? Who knows...

The only thing the scientists know for sure: IT WILL GET COOLER, THEN IT WILL GET WARMER, THEN IT WILL GET COOLER AGAIN, THEN IT WILL GET WARMER AGAIN, ....


http://en.wikipedia.org/wiki/Holocene_climatic_optimum

The Holocene Climate Optimum was a warm period during roughly the interval 9,000 to 5,000 years B.P.


The Holocene Climate Optimum warm event consisted of increases of up to 4 °C near the North Pole (in one study, winter warming of 3 to 9 °C and summer of 2 to 6 °C in northern central Siberia).


This warm period was followed by a gradual decline until about 2,000 years ago.


http://en.wikipedia.org/wiki/Climate_changes_of_535-536

The extreme weather events of 535–536 were the most severe and protracted short-term episodes of cooling in the Northern Hemisphere in the last 2,000 years


http://en.wikipedia.org/wiki/Medieval_warm_period

The Medieval Warm Period (MWP) or Medieval Climate Optimum was a time of warm climate in the North Atlantic region, lasting from about AD 800–1300. It was followed by a cooler period in the North Atlantic termed the Little Ice Age.

Global temperature records taken from ice cores, tree rings, and lake deposits, have shown that, taken globally, the Earth may have been slightly cooler (by 0.03 degrees Celsius) during the 'Medieval Warm Period' than in the early- and mid-20th century


http://en.wikipedia.org/wiki/Little_ice_age

The Little Ice Age (LIA) was a period of cooling that occurred after a warmer era known as the Medieval Warm Period.

Some confine the Little Ice Age to approximately the 16th century to the mid-19th century.[2] It is generally agreed that there were three minima, beginning about 1650, about 1770, and 1850, each separated by intervals of slight warming

Evidence from mountain glaciers does suggest increased glaciation in a number of widely spread regions outside Europe prior to the 20th century, including Alaska, New Zealand and Patagonia. However, the timing of maximum glacial advances in these regions differs considerably, suggesting that they may represent largely independent regional climate changes, not a globally-synchronous increased glaciation. Thus current evidence does not support globally synchronous periods of anomalous cold or warmth over this timeframe, and the conventional terms of "Little Ice Age" and "Medieval Warm Period" appear to have limited utility in describing trends in hemispheric or global mean temperature changes in past centuries.

    Here are a few questions I wrote to ask those stupid uneducated sheeple blindly believing everything told by the establishment.

    You believe in Global Warming theory. Fine, make me believe as well.

    1. Prove to me please that the chart of the average temperature growth in the last 150 years significantly differs from the typical Dansgaard-Oeschger cycle, combined with the typical Mintkovich cycle, taking into account the resonance frequency of the Earth's climate system.

    2. Even if you could prove that, please prove to me that this difference is caused by anthropomorphic factors.

    3. Even if you could prove that as well, please tell me what can we do about it, realistically?

    The Nobel Prize winning U.N. team has admitted to playing loose with facts...and again, yesterday they revealed to be using far less than scientific conclusions, to determine their findings. They now admit they used a students dissertation to "prove" glacial melting trends, and using "eyewitness" reports from unnamed sources as their "evidence".

    It is a farce...and likely criminal. It has given real scientists, shudders at their methods.

    It is not cooling or warming we are discussing now.

    It is all about global FOOLING!


    The Global Fooling

    Noses have turned blue,
    Shivering reigns the street, even November is snowy,
    But people repeat they were taught to:
    “Global Warming, Global Warming…”
    Model consumers, devoted voters…
    They could carry Kerry.

    Say what?

    Look at those charts.



    There is clearly the 100,000 year cycle, and we are at the edge of the next big Ice Age.

    I edited my earlier post.

    http://en.wikipedia.org/wiki/...

    The processes behind the timing and amplitude of these events (as recorded in ice cores) are still UNCLEAR. The pattern in the Southern Hemisphere is DIFFERENT, with slow warming and much smaller temperature fluctuations.

    The events appear to reflect changes in the North Atlantic ocean circulation, PERHAPS triggered by an influx of fresh water (Bond et al.. 1999).

    The events MAY BE caused by an amplification of solar forcings, or by a cause internal to the earth system - either a "binge-purge" cycle of ice sheets accumulating so much mass they become unstable, as postulated for Heinrich events, or an oscillation in deep ocean currents (Maslin et al.. 2001, p25).

    The little ice age of ~400 to 200 years ago has been interpreted as the cold part of a D-O cycle, putting us (even WITHOUT the effects anthropogenic global warming) in a period of WARMING CLIMATE (Bond et al.. 1999).

    Really??????????? But you are absolutely sure that the warming period of the most recent D-O cycle which started around 1850 is actually caused by humankind?????

    You don't have any direct temperature and Solar activity measurements prior to 1850 (the last D-O cycle happened 1700 years ago, of course), but you are absolutely sure that this D-O cycle is different from all the previous ones.

    Even if this D-O cycle is different somehow, where is your proof that humans and not Sun caused that?

    Again, there is 100,000 year cycle, and we are at the edge of the next big Ice Age. Maybe this is the last D-O cycle before sharp decline in temperatures. Maybe it SHOULD be different.

    Dear Neville,

    You mentioned to me some time ago that in your view, the 11-year solar cycle did not influence temperature. There have been numerous attempts by academics to establish a correlation, but each has been shot down on some ground or other. I remember Barrie Pittock was especially dismissive of attempts to correlate solar cycle with temperature.

    Have you tried this approach?

    Load "Mathematica" into your PC and run the following set of instructions –

    data = ReadList[ "c:sydney.txt", Number]
    dataElements = Length[data]
    X = ListPlot[ data, PlotJoined- True];
    fourierTrans = Fourier[data];
    ListPlot[Abs[fourierTrans], PlotJoined - True];
    fitfun1 = Fit[data,{1,x,x^2,x^3,Sin[11 2 Pi x/dataElements],
    Cos[11 2 Pi x/dataElements]},x];
    fittable = Table[N[fitfun1], {x, dataElements}];
    Y = ListPlot[fittable, PlotJoined - True];
    Show[X, Y]

    The reference to "c:sydney.txt" is a suggested pathname for the following set of data - which is Sydney's ...

    Y = ListPlot[fittable, PlotJoined - True];
    Show[X, Y]

    The reference to "c:sydney.txt" is a suggested pathname for the following set of data - which is Sydney's annual mean temperature.

    16. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x.4
    17. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x.1

    17. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x. x x.1
    18.6

    So Far so good. "Mathematica" first plots out the data itself (see Atachment 1)

    The first part of the instruction set lets "mathematica" do a Fourier Transform on the data, ie. searching out the periodicities, if there are any. The result is shown on Attachment 2.

    The transform result shows a sharp spike at the 11 year point (I wonder what is significant about 11 years?). The second part of the instructions now acts upon this observed spike (the Cos 11 bit), to extract it's waveform from the rest of the noise. The result is shown as a waveform in attachment 3, the waves having an 11-year period, with the long-term Sydney warming easily evident.

    Attachment 4 shows the original Sydney data overlaid against the 11-year periodicity.

    It would appear that the solar cycle does indeed affect temperature. (I tried the same run on the CRU global temperature set. Even though CRU must be highly smoothed by the time all the averages are worked out, the 11-year pulse is still there, albeit about half the size of Sydneys).

    Stay cool.

    Yes, my mind is made up. Those are not real scientists. They don't care about the truth but only about government grants. It is stupid to believe anything coming from their mouths. However, you want the whole humankind to change our way of life just because those "scientists" say so?

    I am absolutely sure that the Sun cycles and the orbital movements influence the climate. I am absolutely sure that the Earth had periods of cold climate and warm climate for billions of years.

    You have to persuade me that human influence on the climate is more important now than the Sun.
