Did Climate Change Affect the Hudson Valley, AD 800-1300?

In the Hudson Valley, archaeological sites dating to the period AD 1000-1300 appear to be scarce, or at least relatively invisible to archaeologists.  This trend had been noted, for example, by former New York State Archaeologist Robert E. Funk (1976), and has continued to hold through the era of more recent archaeological research and Cultural Resource Management studies.  Could the Medieval Warm Period have affected Hudson Valley Native American populations in some significant way, such as causing population decline, out-migration, or a reorganization of settlement patterns?
