Climate: studies on Lake Ohrid, increasingly extreme seasons

The sediment of the oldest lake in Europe was examined

(ANSA) - PISA, SEPTEMBER 3 - Recent studies on core drillings and pollens in Lake Ohrid, the oldest in Europe, between Albania and Macedonia, lead a pool of scholars from some Italian universities to conclude that the seasons will be more and more extreme, with hot and dry summers, and greater autumn instability due to heavy rainfall especially between September and December. This could be the future climate trend in the Mediterranean basin, due to global warming emerging from the study of the sediments of Lake Ohrid. The study is conducted by an international consortium led by Bernd Wagner, professor at the University of Cologne (Germany) and coordinated by Giovanni Zanchetta, University of Pisa (Italy). "The forecasts based on the physical-mathematical climate models in the Mediterranean basin after the occurrence of global warming - says Zanchetta - are characterized by wide uncertainties especially about the rainfall trend on which the water availability for over 450 million people depends. To better understand the possible future scenarios it is, therefore, necessary to investigate into the past climate and Lake Ohrid is a mine of useful information about the evolution of the climate in the Mediterranean basin in the last million and a half years".
