Archaeologists have published a new paper in New Scientist that confirms what previous research has shown: numerous periods during recent history have been as warm as or warmer than the present.
The paper, “Climate change has revealed a huge haul of ancient arrows in Norway,” discusses the findings of researchers from the Universities of Cambridge, Oslo, and Bergen.
The researchers discovered a “treasure trove” of arrows, arrowheads, clothing, and other artifacts, recently uncovered by receding ice in a mountainous region of southern Norway.
The oldest arrows and artifacts date from around 4100 BC. The youngest artifacts date from approximately AD 1300, at the end of the Medieval Warm Period.
Because present temperatures are only now exposing some of the artifacts were deposited when no ice covered the ground, temperatures were clearly warmer during the many periods when artifacts were deposited.
Along with the arrows and other artifacts, the researchers found nearly 300 specimens of reindeer antler and bone exposed by receding ice.
Because reindeer presently frequent the area, the archaeologists say they are confident the area has served as an important hunting ground, off and on, for millennia.
The fact that artifacts were found from several different periods separated by hundreds and thousands of years in time indicates the ice and snow in the region has expanded and receded several times over the current interglacial period.
