You will not find a more fervent believer in Earth's changing climate than I.
Not only have I seen it constantly change through my lifetime but I've read the results of ice and lake bottom cores which tell the story of an ever changing atmospheric temperature and chemical composition over tens and even hundreds of thousands of years.
As shown in the image above, there are cycles evident in historical climate data which show mean global temperature variations of fully +/- 3oC through recent human history. This data can be matched up with similar cycles found in the study of tree-ring growth, geomagnetic excursions recorded in rock formations, archaeology plus the cycles of our Sun to create a fascinating picture of Earth's history. (More on the above image after 'Eric The Red')
You know that old saying, “History repeats”? It's true for many aspects of our world, the Sun, our outer planets, distant star systems and our galaxy as a whole.
This is fascinating stuff yet it is not generally taught to students or seen on television. I believe that to be a crime because all of the scientific data made available over the years has been paid for by your tax dollars.
Those who have collected, assembled and published that data are certainly aware of the cyclical nature of everything they study, which means that their failure to disseminate publicly owned natural science (and in some noted instances even try to make historical climate-related events disappear from the record), must be questioned.
This then raises the very important issue of an uniformed public being taught to sacrifice their lifestyles and even their livelihoods in a vain effort to stop something called, 'Climate Change.'
It is precisely this lack of education that has resulted in the state we find ourselves in today, where very few people outside of the scientific community and government know of our 'climate history' and even fewer know of the effect that recurring novae and even Solar cycles have on our Earth and surrounding planets.
Yet EVERYBODY is talking about 'Climate Change'.
Therefore I must ask the question;
If the interests of most people don't include Earth or space sciences then what, to them is a 'Climate Change', and one which might be stopped?
Eric The Red
Rather than waiting for an answer, permit me to go back in time to the era of Vikings and their settlements of Greenland and what is now Western Europe and Eastern Canada. This appears to be a history known to many people and of some interest given the popularity of Viking-era television, although you would not want to base your history thesis on the theatrics.
Several questions have plagued me about Viking history since my first hearing of it as a young student, but the addition of historical climate data into archaeological timelines has relieved me of that burden. I have employed 'inter-disciplinary study' to put historical events into context.
Why did the people we know as Vikings seem to appear on distant coastlines and then disappear almost as quickly? Assuming that the Vikings did not just fall from the sky before they started sailing about, what was the impetus for their exploration and expansion, and is it related to their disappearance from history less than four centuries after they set out?
Also, given what the Island looks like today, who in their right mind would call it Greenland?
I offer this excerpt from a well written article by S Jay Porter who has used inter-disciplinary study to place many aspects of Viking-era history into context:
“In 891 AD. Eric The Red set off from Iceland with a few followers to explore a land to the west which they had probably spotted some time before while sailing out in their longboats, and then returned three years later with about 500 fellow Vikings. At first they settled on the south-east coast, close to the tip of this new land and then, as the population grew, created a further settlement to the south-west. They called their new home ‘Greenland’.
It has been said that this name was a ‘spin’, a publicity stunt to entice more Vikings to come to join the new settlers, but this would have been pointless if it had been impossible for them to survive. They must at least have been able to create their own dwellings, build their own fires, make their own clothes and above all, grow their own food. The settlers might have been able to trade such things as polar bear-skins and fox furs for iron and other necessities on occasional trips to Europe, but their compatriots in Denmark and Iceland would have been neither able nor willing to row their longboats out each month with groceries.
At present, the temperatures in Greenland range from a maximum of 7C in July to -9C in January. This is too cold for grain such as wheat and even rye to grow and ripen in the short summer of such northern latitudes. Nor are sheep and cattle happy at those temperatures. Hill sheep might be able to nibble away at moss and short grass, but cattle need lush meadows and hay to fatten and live through a winter. Solid wood is needed for building, boat building and warmth, but only bushes and such weak trees as birch now grow in Greenland.
In 1991, two caribou hunters stumbled over a log on a snowy Greenland riverbank, an unusual event because Greenland is now above the treeline. Over the past century, further archaeological investigations found frozen sheep droppings, a cow barn, bones from pigs, sheep and goats and remains of rye, barley and wheat all of which indicate that the Vikings had large farmsteads with ample pastures.
The Greenlanders obviously prospered, because from the number of farms in both settlements, whose 400 or so stone ruins still dot the landscape, archaeologists guess that the population may have risen to a peak of about five thousand. They also built a cathedral and churches with graves which means that the soil must have been soft enough to dig, but these graves are now well below the permafrost.
There is also a story in ‘Landnamabok, the Icelandic Book of Settlements, which tells of a man who swam across his local fjord to fetch a sheep for a feast in honour of his cousin, the founder of Greenland, Erick the Red. Studies of Channel swimmers show that 10C would be the lowest temperature that a man would be able to endure for such a swim, but the average August temperature of water in the fjords along the southern Greenland coast now rarely exceeds 6C.
The water at that time must therefore have been at least 4C warmer and probably more than that which means that the summer temperatures (for the air) in the fjords in southern Greenland would then have been 13C-14C, as compared with the present temperatures mentioned above.
It follows that temperatures must have been higher than those of today’s during that first settlement of Greenland which lasted from approximately 900 until the mid-1400s AD, when these settlements died out. There is no written explanation for this sudden demise but climate scientists have discovered that Iceland, like the rest of Europe, was gripped by a rapid and centuries-long drop in temperature, known as the Little Ice Age.
And in a recent study, William D’Andrea and Yongsong Huang of Brown University, Providence RI have traced the variability of the Greenland climate over a period of 5,600 years when previous inhabitants were also subjected to rapid warm and cold swings in temperatures.”

NOAA Greenland Ice Core Temperature - Title Image
In 2004 the United States National Oceanic and Atmospheric Association (NOAA) published historical temperature data taken from ice cores on Greenland which show rapid and wide atmospheric temperature variations over the past 10,500 years. It, along with a host of historical temperature and climate data can be found here.
Overlaying the temperature curve (title picture) are highlights of human development and the rise and fall of races and civilizations.
At that point on the temperature curve which represents the last 250-years of human history is shown 'The Mann Hockey Stick', which is the tiny window of atmospheric history upon which post-normal science has based its future CO2 and Global Warming predictions.
What Our Future Holds
If the United States National Oceanic and Atmospheric Association and a host of other academic and government organizations around the world believe that our climate changes, then so must I.
Another belief which normal science holds through the laws of physics and real world observation, is that warm air can hold more moisture than cold air. Post-normal science believes, without proof that the opposite is true and that the world will burn up should our mean global temperature rise a few degrees.
Here is a link to results of a paper released in 1999 which studied ice cores drilled into the ice over Lake Vostok on the continent of Antartica. These graphs plot mean atmospheric temperature and CO2 concentrations back 400,000 years and they display an amazing temperature cycle repeating every 90,000 to 140,000 years. In fact they are indicative of what we know at the 100,000 year Glacial Cycle.
Looking at those graphs and the patterns they present, it is not hard to recognize the direction in which our climate is headed as we enter a new glacial cycle.

“All across the world, in every kind of environment and region known to man, increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real. Not only is it real, it's here, and its effects are giving rise to a frighteningly new global phenomenon: the man-made natural disaster.”
BARACK OBAMA – speech April 03, 2006
“The good news is we know what to do. The good news is, we have everything we need now to respond to the challenge of global warming. We have all the technologies we need, more are being developed, and as they become available and become more affordable when produced in scale, they will make it easier to respond. But we should not wait, we cannot wait, we must not wait.”
