Description :
Vegetation apparently responded in concert with fluctuating climatic and glacial episodes. Climate did not support the development of structurally closed forest until the cool and humid late Holocene. With reactivation of glaciers during recent milennia, vegetation has been altered by a series of stadial and interstadial events. Current interglacial climate trends appear to involve a shifting pattern in the duration and intensity of seasonal atmospheric circulation centers over the North Pacific Ocean. Climatic-gacial forcing recorded in these studies is attributed to changes in solar radiation, among other factors.
