Description
Frank Sirocko and eight co-authors read a lake sediment core layer by layer to watch Europe dry out at the start of the last ice age. Their 2026 study uses yearly layers from a filled crater lake at Hoher List in Germany's Eifel hills. The warm Eemian age was ending, and its mixed forest, rich in silver fir, stood on the shore.
The collapse came in pulses. A first dry pulse lasted about 250 years, followed by 750 years of forest recovery. A second pulse ran at least 750 years, then a shorter boreal phase. A third pulse brought falling lake levels, grassland spread, and cold summers. The fir vanished and fires grew common within years at each turn. The whole shift took at least 2,700 years, yet each drying struck within decades.
