Mongolian Melting Glaciers
One of the byproducts of climate change is that previously inaccessible artifacts of history can meet fresh air for the first time in millenniums. One reason that artifacts trapped in ice are crucial to researchers is that the ice naturally preserves objects, which means even organic artifacts such as campfires and meals are available to historians.
For example, after a significant portion of a Mongolian glacier melted away, scientists found everyday objects such as ropes made from twined animal fur. These discoveries give us a better idea of how the earliest human societies operated in unforgiving climates, such as the Mongolian steppes. Another classic example of the treasure of information well preserved through glacial preservation!
