Warmer than today for most of the last 10,000 years

GISP Greenland Ice Core Data shows that it has been warmer than today for almost all of the past 10,000 years.

Not only warmer, it shows that temperatures have been declining – in a zig-zag fashion – for several thousand years.

Here’s a different view using the same data:

  1. It’s such a revealing graph. When you know that an interglacial cycle is just about this long..yes..the “Little Ice Age that Dr. Abdussamatov is warning about, to start around 2014 just seems more likely to be the 70,000 year glaciation cycle that Professor Vladimir Paar warned may start about the same time slot give or take a couple years.

  2. John,

    another way of looking at the data is that the system experienced a major perturbation and is now settling back down.

    • I agree because, if you think in terms of long time spans, the average temperatures in the last 500 kyears have been much lower than now and the whole interglacial periods look more like local perturbations of the general trend.

  3. I agree John, I wounder if the temp pretty well flat lined at a colder then average temp. like this, right before the last ice age. Guess with low sunspot count (Might be blank sun tomorrow) if get some large scale volcanoes then we go into an ice age. Scary!

  4. Well, during Roman Empire there was wine production in UK and turtles in Denmark thus indicating higher temperatures than today

  5. Thanks to Leon for the chart
    Looking at the chart I noticed a very interesting (approximate) date.
    See the chart here http://i1237.photobucket.com/albums/ff474/PhilippinoBob/Untitled-2.jpg
    I am not a religious man, I used to work as a technical stock market analyst and I was amazed by this incredible coincidence. It is a fairly rare occurrence because it is a harbinger of a new trend.
    In this case, the cooling trend. Notice the following two unsuccessful temperature peaks.
    Now, let me ask you fellows here: do you believe in coincidences?… because I don’t!

  6. Let me add this as well.
    By using the technical analysis I arrive to a hypothetical conclusion that temperatures will drop down to -34C.
    That is only 2 degrees drop but a drop that will be like anything we’ve ever experienced!
    Here is the the hypothetical -2C drop on the chart.
    This chart is for Greenland and not for more southern regions, therefore it will play out differently in those regions. However, no matter how you look at it, a drop up-north will affect south as well. So be prepared!

  7. In some immortal words from the film Carry On Cleo:
    Julius Caesar; “It’s supposed to be the Season Of The Golden Breezes”
    Mark Anthony; “More like the Season Of The Brazen Monkeys”
    I say this because it is colder than normal here (even for Britain)… and guess what!
    My employer has deemed fit to give me my fortnight summer leave wc 23rd April this year!!
    I wish the AGM-hot-air-spouters were right, at least then I might get some decent weather for my summer hols…

  8. Great chart !

    I used to argue like crazy long ago (back in the late 1990’s thru about 2005) about global cooling on weather.com chat boards. (they are long gone now)
    We had some great discussions and arguments. Some went ugly which nearly had me banned – including easternusweather.com at one point, LOL. Back then, mostly before 2003, almost everybody, it seemed, was on the global warming bandwagon and I insisted that this theory was just plain wrong.
    However, I noticed after 2003 I had far fewer arguments against global cooling then before that time. Wish I could have presented this very useful temperature chart and website (iceagenow.com) to them in the late 90’s ! They would have been surprised !!

    • I myself used to be a “believer” in GW, and AGW, until about 2005, but there was an important drop in temperature in 2006 and all those predictions about increased storms everywhere, tornadoes, etc., that didn’t happened that year and 2007, 2008, etc. made me review my belief.
      GW has only one basic problem: it doesn’t match the facts.

  9. So it was those evil Minoans releasing all that co2 that caused global warming back then. Well we know what happened to them. Ah well, its all Greek to me.
    But seriously I am glad to see that despite the best efforts of the agw crowd these events could not be erased from the geologic record. It will be interesting to see how they try and spin this.

    • It’s impressive how this smooth downward parabola fits the ice core data so well.
      It suggests that we’re going back now to where it was some 12,000 years ago: another Ice Age, and this is not the only data suggesting the end of the present interglacial.

  10. It’s interesting to see that at the end of the minoan warm period we have the ‘Dark age’ one of the most severe civilisation collapse ever. They even lost writing! It’s also interesting to see that at the end of the roman warm period we have… another so called ‘Dark age’. And at the end of mediaval warm period… starvation, pandemia, and other joy of colling.

    Nevertheless warmist are telling us that Warm is bad…

  11. I believe that levels of CO2 in the atmoshere have absolutely no effect on the climate. It is my opinion that what is really behind climate changes, warming or cooling, is fluctuation in the amount of COSMIC RAY INDUCTION, bringing on ups and downs in the amount of volcanic activity. Although it is not the present day fashion to do so, nevertheless for entirely scientific reasons, I hold to the HOLLOW EARTH THEORY. Often people do not want to believe that stars and planets are hollow because they cannot understand where volcanic activity is coming from. In their mind if the Earth is hollow then where is the volcanic activity coming from they ask. Well in my opinion the crust of the hollow Earth is no more than 50 kilometers thick. That crust is being hotted up by COSMIC RAY INDUCTION, which is also the driving force for gravity and magnetism too. I see volcanic activity as being a typical electronic phenomenon. Static charge building up in the crust, which then sporadically releases the accumulated energy as the charge over comes the natural electronic resistence of the crust, thus bang, volcanic activity. Thus in my understanding there is no such a thing as a dead volcano. Extinct volcano’s do not exist. I am told that every planet in our solar system has been getting warmer over the past decade. How can we explain this ? Only if we accept that global warming is as a consequence of the increase in the amount of Cosmic Ray energy penetrating the solar system. Increasing because of the collapse of the heliospheric bubble, brought on by fewer sun spots. So that the temperature variations found in the Greenland Ice Cores is probably a very good record of Cosmic Ray fluctuations too. In my opinion the existence of plate tectonics is very clear proof that the Earth is obviously hollow. Also crustal displacement, as proposed by Albert Einstein and Professor Hapgood, is therefore even more likely than ever they thought it to be.

  12. Are we sure that Greenland was in its present position all those millenia ago? Continents do drift around.Does anyone know for sure where Greenland was at the time these temperatures were said to have ocurred ? There was talk of iceball earth.

  13. Sorry about my silly comment,above,about continental drift.I recollected reading that the fact that fossils of tropical animals had been found far north,(I recollect in Finland,)but that this did not prove todays Finland once had a tropical climate,the reason being that the piece of the earths crust that we now call Finland was once much further south.But of course continental drift is negligible over 10,000 years so my comment was silly. I should have looked at the time scale more closely.Stupid.Sorry.

  14. We are also due for a “Bond event” which happens every 1 470 years or so. The last one was around 540 AD (Dark ages), the previous one ended the Minoan warm period.
