Abstract

Palaeoclimatic characteristics based on paleogeographic reconstructions for the optimumsof the Holocene and the last interglacial appear to be close in estimated range of globalwarming to those expected in the current century according to IPCC (scenario A1B). Reconstructionsof the state of environmental components in Northern Eurasia under given seasonaland annual temperature and precipitations allowed developing scenarios of expected changes inecosystems within individual landscape zones. Regions of most probable appearance of instabilityin ecosystems are mostly confined to northern lowlands (permafrost degradation), plains inthe southern East European Plain (accelerated erosion) and southern mountains (mudflows,landslides, etc.).

Keywords: palaeoclimates, global warming, ecosystems, prognosis, relief-forming processes, Northern Eurasia
