Beginn der Kleinen Eiszeit

Eine neue Untersuchung etwa zum Beginn des Spörerminiums:

Die 1430er Dekade scheint die kälteste Zeit des Milleniums gewesen zu sein.
CP - Abstract - The 1430s: a cold period of extraordinary internal climate variability during the early Spörer Minimum with social and economic impacts in north-western and central Europe

"One decade in the 15th century was the most miserable, bitterly cold winter for hundreds of years, causing famine and disease across Europe, an international group of researchers has found. Using multiple lines of evidence from different scientific disciplines, the scientists have managed to reconstruct this ancient climate change to learn how Medieval Europeans dealt with the ravages of the cold on their food supply — and how we can learn from their mistakes.

In a new study out today in the journal Climate of the Past, the research team, led by Chantal Camenisch at the University of Bern, Switzerland, investigated a curiously cold period from 1430-1440. Camenisch, an historian, discovered when looking through historical records that numerous references were made to wine frozen in bottles in Scotland, to frozen lakes and rivers in central Europe, and to extreme cold even as far south as Italy. This find intrigued Camenisch, since cold temperatures in the 1450s are well known, but this earlier time period was a bit of a mystery. “I realized that there was something extraordinary going on regarding the climate during the 1430s,” she says."
