Recent archeological discoveries on the Viking settlements in Greenland, along with various historical records, disprove the theory of man-made global warming. This information is of utmost importance as Congress considers sweeping legislation intended to combat global warming supposedly caused by human activity.
The Vikings settled Greenland in the 980's AD. Archeologists estimate that three to five thousand Scandinavians lived in three main settlements there at the height of the colonies' success. Over 400 farms in Greenland have been excavated along with the remains of eleven or more churches.
The colony was so successful that in 1126 a Catholic diocese was founded at Garðar, Greenland (now Igaliku). The Catholic Church sent several Bishops and a number of priests to Greenland to serve the congregations there.
The Greenland settlements at that time could be successful because the climate was far warmer than today. Archeological excavations have revealed extensive birch woodlands with birch trees up to 6 meters high in the area around the inner parts of the Tunuliarfik and Aniaaq fjords, the central area of the Eastern settlement. Excavations and various written records have also shown that the hills grew lush grass and willow brush. This vegetation was due to the Medieval Climate Optimum, an extended period of warm climate that made Viking-style life in Greenland feasible.
