Deforestation of Europe.

Humans have transformed Europe's landscapes since the establishment of the first agricultural societies in the mid-Holocene. In this study the group of Prof. Kaplan Jed Oliver (Atmosphere Regolith Vegetation - ARVE) created a very high resolution, annually resolved time series of anthropogenic deforestation in Europe over the past three millennia and provide reasonable estimations of deforestation in Europe. They simulate extensive European deforestation at 1000 BC, implying that past attempts to quantify anthropogenic perturbation of the Holocene carbon cycle may have greatly underestimated early human impact on the climate system.
