The paper presents unique data of plutonium (241)Pu study in seabirds from northern Eurasia, permanently or temporally living at the southern Baltic Sea coast. Together, ten marine birds species were examined, as follows: three species that permanently reside at the southern Baltic, four species of wintering birds, and three species of migrating birds; 366 samples were analyzed. The obtained re...

Aggregate annual discharge from the six largest Arctic-draining Eurasian rivers achieved an all-time record high in 2007, accentuating a long-term upward trend that argues for intensification of the Arctic hydrologic cycle. This record discharge was due in part to strong positive anomalies in late winter snow water equivalent across much of northern Eurasia. These anomalies arose in response to...

An examination of the Northern Hemisphere winter surface temperature patterns after the 12 largest volcanic eruptions from 1883-1992 shows warming over Eurasia and North America and cooling over the Middie East which are significant at the 95% level. This pattern is found in the first winter after tropical eruptions, in the first or second winter after midlatitude ruptions, and in the second wi...

The initial expansion of anatomically modern humans (AMH) occurred during a hyperarid event in Africa that occurred 135-75 ka. Large-scale AMH spread in northern Eurasia started during the Middle Weichselian glacial maximum, and proceeded during the subsequent mild interstadial (60-40 ka ago). This expansion which encompassed the polar regions and southern Siberia proceeded at a remarkably rapi...
