Nice try though. Not quite as thorough as the Medieval Warm Period Project, although it will help improve our understanding.
As many people know, human civilization arose during a particularly stable period in the history of the earth – the Holocene, encompassing the 12,000 years since the end of the last ice age. It may have been no accident that civilization burst forth during an era when ice had retreated from some of the most favorable land and when climate, sea level and other conditions had settled down after the turbulence of the ice age.
But they have not entirely settled down. The Holocene does feature some large-scale climate oscillations, including two recent ones — the Medieval Warm Period and the Little Ice Age – that have been the focus of a great deal of discussion and research within mainstream climate science. The Medieval Warm Period, from the 10th to the 13th centuries, is also beloved by climate contrarians. They would like to claim that conditions worldwide were warmer than they are today and that this somehow proves that humans cannot be influencing modern climate.
But evidence has been accumulating for several years that these events and other examples of Holocene climate variability were generally not global in scope. Now, a group of researchers led by Aaron E. Putnam of Columbia University may have come pretty close to nailing the case.
