Researchers Study Europe’s Oldest Lakes to Map Climate Change of 1.36 Million Years

Investigating sediment cores from the bedding of Europe’s oldest lake, an international group of scientists has created a detailed climate early part of the north-central Mediterranean longing back to 1.36 million years and showed the climate mechanism that has pushed the winter rainfall in the area.

The scientists, together with Dr. Alexander Francke from the University of Wollongong (UOW), drilled into the bedding of Lake Ohrid, which lies on the border of North Macedonia and Albania and is considered to be the oldest lake in Europe. The study was directed by Associate Professor Bernd Wagner from the University of Cologne and Dr. Hendrik Vogel from the University of Bern.

The results of their investigation are published within the scientific journal Nature.

By providing an unusual perception of the elements which have propelled the Mediterranean region’s climate earlier, the data they amassed will help scientists to model extra accurately the region’s future climate following global warming.

The drilling came about in water 245 meters deep and reached a maximum depth of 568 meters into the sediment. The analysis revealed that Lake Ohrid first established 1.36 million years in the past and has existed repeatedly since then. The great sediment succession enabled the researchers to reconstruct climate over the complete history of the lake in fine detail.

Geochemical data and the pollen file present that winter rainfall increased within the north-central Mediterranean area throughout warm, interglacial periods. Throughout these intervals, climate model simulations point out increased cyclogenesis (the event and strengthening of the low-pressure regions within the environment) over the Mediterranean Sea during summer and late autumn leading to considerably higher winter rainfall.
