Tree Ring Studies Confirm Global Cooling

Contributed by Chriss Street. Specialist in corporate reorganizations and turnarounds, former Chairman of two NYSE listed companies. His latest book, The Third Way, describes how to achieve management excellence and financial reward by moving organizations from Conflict and Confrontation to Leadership and Cooperation. He lives in Newport Beach, CA.
The prestigious Nature Journal recently published a major climate change study named Orbital Forcing Of Tree-Ring Data that proves through analysis of over 2000 years of tree ring evidence that current climate models substantially underestimated ancient Northern Europe temperatures levels during the Roman and Medieval Periods. The fact that temperatures have trended down for the last two centuries debunks theories that anthropogenic (man-made) global-warming is caused by a rising CO2 gas levels associated with industrial burning of âfossil fuels.â
Researchers from Germany, Finland, Scotland, and Switzerland examined tree-ring density profiles in trees from Finnish Lapland. In this extremely cold environment, trees often collapse into one of the numerous lakes, where they remain well preserved for thousands of years. The international team was able to conduct high reliability calculations of tree ring density from the cold water preserved Scandinavian pine trees, which correlate very closely with annual summer temperature patterns.
