Younger Dryas
The eruption was discussed as a possible cause for the Younger Dryas, a period of global cooling near the end of the last glacial maximum that appeared to coincide with the time of the Laacher See eruption. However, an improved dating of the onset of the Younger Dryas in Europe, published in 2021, showed that it began about 200 years after the eruption, ruling it out as a potential cause.
