One of my greatest issues with a human-driven ‘global warming’ theory is that there are a variety of objective, historical climatic warming and cooling events that couldn’t possibly be human influenced because industrialization just didn’t exist then.
In his revolutionary climatological book, “The Chilling Stars”, Henrik Svensmark points out this obvious issue as he fights for recognition of his exciting natural-driven climate theory against ‘global warming’ alarmists that require a human-driven component to protect their professional, financial, and political ambitions:
“The Medieval Warm Period and the Little Ice Age were an embarrassment for those who, in recent years, wished to play down the natural variations in climate that occurred before the Industrial Revolution. A widely publicised but now discredited graph of temperatures, produced in 1998 by Michael Mann of the University of Massachusetts and his colleagues, tried to iron out the variations. Lampooned as the hockey stick, Mann’s graph showed the world remaining almost uniformly cool through most of the past 1000 years until 1800. Then temperatures began to climb towards unprecedented highs in the late 20th century- so making the toe of the hockey stick and the supposed onset of an unprecedented episode of man-made global warming.”

So is this a subjective battle of who ever can rally the largest media megaphone or numbers for their climate opinion? No. We have to have objective, physical evidence to figure out the one, scientific truth of what really happened. The above quote is important because it comments on a very interesting discovery in the recent warming (and still not even as warm as the recent Medieval Warm Period) of 2003 in Europe. During that hot summer, a couple hiking up in the Swiss Alps found a bark quiver that scientists were amazed to discover was 4,700 years old! Why should we care? Well, Svensmark notes:
“The hiking couple had unwittingly rediscovered a long-forgotten short-cut for travellers and traders across the barrier of the Swiss Alps. To keep treasure-hunters away, the find remained a secret for two years while archaeologists scoured the area of the melt-back and analysed the finds. By the end of 2005 they had some 300 items- from the Neolithic Era, the Bronze Age, the Roman period and medieval times.”
Global warming theory proponents would say “Look! All these things were exposed to warn us of our imminent man-made doom!” Instead, real scientists noted the various period items were clustered in warm intervals when the pass of Schnidejoch was open, offering a short passage to and from the fertile Rhone valley south of the Alps. These physical pieces of history indicate that the climate had reached levels at least as warm as the current temperatures several times in the past for these physical items to accumulate in the Schnidejoch Pass. There were no Neolithic or Roman SUV’s or overly-flatulent animals spewing greenhouse gases that can be blamed for the multiple warmings and coolings that opened and then froze/closed this advantageous travel route. This is real evidence tied to the real world we can understand- unlike theoretical models and speculations that underlie the human-driven ‘global warming’ theory.
This one instance of hard, scientific evidence alone creates a massive hole in the current junk-science of human-driven ‘global warming’.
