INTRO: The most severe droughts in the ancient Eastern Mediterranean arose when multiple natural climate cycles coincided, according to a new study from Stockholm University published in Science Advances. The findings shed new light on the climate conditions surrounding the Late Bronze Age collapse and may help improve understanding of future drought risks in a warming world.
“Rather than being caused by a single climatic event, we found that the most extreme droughts emerged when natural climate cycles operating over different timescales coincided. This helps explain why the drought associated with the Late Bronze Age collapse were so severe”, says Katherine Power, PhD student, Department of Physical Geography, Stockholm University, and first author of the study.
Severe droughts and widespread societal collapse
Around 3,200 years ago, many of the great civilizations of the Eastern Mediterranean, including the Mycenaeans, Minoans and Hittite Empire, experienced widespread societal collapse. Although severe droughts have long been linked to this period, the climatic processes behind these events remain uncertain. To investigate this, Katherine Power and Qiong Zhang, professor in paleoclimate modelling, Department of Physical Geography, Stockholm University and co-author of the study, used a state-of-the-art climate model to reconstruct the evolution of the Mediterranean climate over the past 8,000 years.
“Our results show that the region underwent a gradual drying trend over thousands of years, driven by slow changes in Earth’s orbit. Superimposed on this long-term trend we also found shorter-term fluctuations in the Atlantic Ocean and atmosphere”, says Katherine Power... (MORE - details)
