Climate change facilitated the early colonization of the Azores Archipelago during medieval times
We use a diverse set of lake and landscape proxy indicators to characterize initial human occupation and its impacts on the Azores Archipelago. The occupation of these islands began between 700 and 850 CE, 700 years earlier than suggested by documentary sources. These early occupations caused widespread ecological and landscape disturbance and raise doubts about the islands' presumed pristine nature during Portuguese arrival. The earliest explorers arrived at the end of the early Middle Ages, when temperatures were higher than average, and the westerly winds were weaker, facilitating arrivals ...
