Ancient Climates and the Modern Cult of Climate Change

How I became interested in the climate change debate:

In the year 2000, I was for a while in Newfoundland and Labrador. I had a couple of weeks free, and decided to take my son to see the 1000 year anniversary of the settlement at L'anse Aux Meadows, at the very tip of the Island of Newfoundland, Canada's Eastern most Province.
Today the park, archaeological zone, and reconstructions of the settlement are very remote, but easy enough to reach for a determined North American traveller. I say that because my European friends think a 30 minute drive or bus ride is a vast distance - and this takes several hours from the ferry port in the south, or 14+ hours from the Provincial capital of St John's. But it a beautiful scenic drive past Fjords and mountain lined coasts on a modern Highway called 'the Viking Route' or 'Sea to Sky Highway'. Eventually you end up in St Anthony's, a small , but full service, town on the top of the Island on the coast known as 'Iceberg Alley', which as the name implies is a great place to view Icebergs in the summer, as they drift by and break up off the coastline.
The adventure would have been wonderful if it had just been about the natural beauty of the place, but being a life-long student of medieval history, I found it to be a wonderful experience to visit the ONLY confirmed site dating to the middle ages in Canada.
Once there I immersed myself in the 'Sagas', or Norse tales of the first landings, colonization, and eventual abandonment/dissolution of the settlements in Newfoundland and Greenland. These are fantastic sounding stories, but backed up by real data. The data consists not just of archaeological finds, but of genetic traces in the native populations of these regions.
One of the aspects that struck me the hardest about these Sagas is the way the land is described in them in contrast to what it is like now. These tales tell of wild fruits growing, including grapes (one region was known a 'Vinland' for exactly that reason), abundant woodlands, and very different types of sea life. These too have left traces. But today, and for hundreds of years, this land is much different. In is a grassy plain, spotted here and there with small forests of stunted pines. Only the moose and the squirrels remain - along with a very hearty bread of fishermen.
So, what happened prior to the year 1000 AD that created a warmer climate in the Northern Hemisphere? I have heard all sorts of stuff, most of it based on pseudo science and conjecture.
What we actually have is an enigma. A cycle presents itself that is evident throughout the historical record. The world warms and it cools. Sometimes the changes seem to be global. In other cases it seems to be regional.
What is evident about the changes we see today is not the causes or end results. We are almost as much in the dark on these important questions as the Norse were.
What is truly apparent is the modern astrologers, known as climate scientists, know the shift is coming. Like some ancient skryer or star-priest who knows an eclipse is approaching, they USE that change to their advantage by pretending to know the reason WHY and how to appease the angry Sun god. Just as the ancient seer was a tool for the people in power, so is our modern scientific community. Just as the ancients required, they seek the blood of infants and innocents and heavy taxes on the common man. We must 'sacrifice' in order to save 'the earth'. Only today they call the sacrifice 'abortion', 'euthanasia', 'eugenics', 'population control' or the ever popular 'bioethics'.

I will sum it up with a verse that says it all, from the good Book:

"The thing that hath been, it is that which shall be; and that which is done is that which shall be done: and there is no new thing under the sun."
Ecclesiastes 1:9
